Biographical sketch:

Little Mel, the young Missouri sodbuster.
Melville Beardsley was born in Kansas City, Missouri on 10 October, 1913, to George and Ella Whitnel Beardsley. His father and grandfather Beardsley were attorneys. He was the third generation of his family to graduate from the University of Illinois, where he took a degree in mechanical engineering. From childhood he was fascinated with flight, and soon after college he joined the US Army Air Corps as a pilot. By the time World War 2 broke out, he was one of the Army's few experienced pilots and spent the war years as a flight instructor at Hondo Field, Texas.
The Army (and later Air Force) sponsored post-graduate education in aeronautics and management at Georgia Tech and the University of Chicago. He was USAF project officer for aircraft development projects, including Northrup's famous "flying wing."
A biographical article was published in the Kansas City Star newspaper on 3 January, 1960, which describes his involvement in early air-cushion vehicles. The full text of this article follows:
His Air-Cushion Car Is Tried by Army and Marines
Patents of a former Kansas Citian Involve Vehicle That Moves 15 Inches Above Ground -- In School Days Here, a Glider in Garage Caused Worry as "Mel" Beardsley Studied Flight Principles -- Grandson of Former Mayor.
by John Alexander [A Member of The Star's Staff]
YOU'RE driving along in a car that has no wheels. The sensation is
amazingyou have a feeling of floating. You're riding along on a springy
cushion of air. You come to a river and you simply float across the surface of
the water without getting wet. Such a vehicle may be the car of the future, if
the invention of a former Kansas Citian is perfected. He is Melville W.
Beardsley, a grandson of a former mayor of Kansas City, Henry M. Beardsley. His
father was the late George D. Beardsley, lawyer and a United States
commissioner here. The air-cushion car was an inevitable topic of conversation
with Beardsley and Kansas City friends while he was visiting here last week.
One of them asked him: "Mel, how long will it be until we can take one of
those things out on the turnpike?" "We're not quite that far along
with it," Beardsley said. "For one thing, the 'puff' of wind from a
passing car would cause you to veer off to one side."
Tryout by Army.
But Beardsley, pointing out that certain types of airplanes, for example, were
available for special use long before they could be turned over to the public,
said the military was already "very interested" in air-cushion cars.
"We've produced the only vehicles the government has purchased and is
operating," he said. "The Army has one of the vehicles and the
Marines have one and they're giving them a workout to see what their
possibilities might be in combat." For civilian use the possibilities
would be truly startling. No wheels, no tires, no axles or shock absorbers,
brakes, springs or conventional steering mechanisms; no transmissions, no gear
shifting. Not even any highways in the usual heavy-load bearing sense. One
suggestion is that a smooth road surface for air-cushion vehicles could be
prepared for a few hundred dollars a mile! Oddly enough, the public's first
contact with the air-cushion principle has come far ahead of the wheelless car
in the form of a certain kind of vacuum cleaner. On the market for the past two
years, this machine exhausts the air through the bottom in a manner that causes
the cleaning unit, which weighs about fifteen pounds, to skim just above the
floor. Beardsley said the firm of which he was a co-founder, National Research
Associates of College Park, Md., is pioneering another air-cushion use which
may find its innovation in amusement parks.
Scheme for Amusement.
"It will be a 'flying saucer' ride," Beardsley said.
"Space-minded youngsters will love it and it will give grownups an idea
of what is ahead in the way of transportation." A slender man of 46, 5
feet 7 inches tall, Beardsley presents the appearance of an average
good-looking man of brown eyes and thinning black hair. But when he talks about
the prospects of air-cushioned locomotion, the pace of his thinking process is
reflected in judicious choice of words, in a pensive manner of tamping his
pipe, in making freehand pencil sketches of models made and models planned.
This is the thoughtfulness that flew in the face of the Beardsley family's
2-generation tradition of lawyers. It started in his boyhood, while the family
home was at Fifty-eighth street and Pennsylvania avenue. The sight of airplanes
buzzing through the sky fired Mel's youthful imagination. He knew that nothing
in the world would ever be able to compete with the excitement of flying.
Worry for His Mother.
Remembering those days, Beardsley said: "Model planes started me off. I
can't even remember when I began making themI was just a kid in Bryant
school." His mother, Mrs. George D. Beardsley, 407 Ward Parkway, remembers
the worry that filled her mind while Mel was building a glider in the 2-car
garage at their home. "It wasn't two cars in the garage, thoughit was
just a car and the glider," she recalled. "Mel built it with care
he weighed everything that went into it. He was going to take it out in the
country and fly it off a steep hill; that's what worried us." Mel's
father, who died in 1936, often took his son to the airport to watch the
planes. The father's main interest was cars, however, and he encouraged Mel and
his brother, Henry, who lives in Miami, to tinker with jalopies. Mrs. Beardsley
believes that the boys' long summer trips in repaired jalopies saved the day
for Mel he never found time to launch the glider. One of those car trips was
a 7,000-mile saga that included California and New Orleans. "When the boys
parked the car in the back yard after that trip, it just sort of sank down and
collapsed," Mrs. Beardsley said. "We finally had it towed away."
Anyway, it came natural to Mel to favor more exciting activities than contracts
and torts, and after his graduation from Southwest high school he sought out
aeronautical courses at the University of Illinois and was graduated in
mechanical engineering in 1935.
Learns to Fly in Army.
With his fresh new diploma in hand, Beardsley did not look for a job. He still
was interested in flying, so he entered Army Air Corps flight training at San
Antonio. "This was the answer to a lifetime ambition," he said.
"It was tough, but it was wonderful. The Army was saving money by not
commissioning us; they just kept us on a year in active duty as flying
cadets." Cadet Beardsley spent his year at Mitchell Field, Long Island.
Then, still fascinated by the technical aspects of flight, he spent a year in
Georgia Tech, Atlanta, as a research assistant in the engineering experiment
station. He stayed on another year as a research fellow and delved into a
project that bore no relation to powered flight. These were studies in
processing flax so it could be worked in the cotton machinery of the South.
After receiving his master's degree in 1939, he had varied experience with
Chrysler and with an Indianapolis firm that was experimenting with a new-type
ignition system. Then, going with the Civil Aeronautics Authority, he was
assigned to the Kansas City office as a power plant specialist. But the war
clouds soon broke, and he was ordered to active duty as a First Lieutenant.
"They sent me back to San Antonio," he recalled. "I was part of
a cadre forming a navigation school. They moved us over to Hondo, Texas, in
1942."
Worked on the Snark.
Later he was assigned to 'the B-32 project at Wright field, Dayton, Ohio, and
in March, 1946, was discharged as a Lieutenant Colonel. For a time he was an
aerodynamics engineer for Northrup aircraft in California, and assisted with
preliminary design studies of the guided missile now known as the Snark. One
thing that annoys Beardsley is criticism of the Air Force for lagging with
space programs. "Years before Sputnik," he said, "we were
considering operations in space, and attempts were made to lay the
technological groundwork for these. But even any use of the word 'space' was
forbidden then by explicit directive from the Defense department." Early
in 1949 Beardsley was tempted away from aerodynamics to help develop a vacuum
process for pre-cooling lettuce. He became vice-president of the concern, with
headquarters at Salinas, California. The cooling method has been employed
widely through the lettuce industry, but Beardsley didn't get a chance to stay
with it. Korea came along, and in June, 1951, he was called back to active
duty. Not that Colonel Beardsley got to Korea. "Here I am, a real
old-timer with the Air Corps; two wars, and never out of the country," he
says. Instead, he was sent back to Wright Field in the Air Research and
Development command. He returned to civilian life as a Colonel in the reserves,
In May, 1958. With another former officer, William H. Alper, he formed the
National Research Associates, Inc., to develop air-cushion equipment. They have
shops in Laurel, Md., with 15 employees and a rustic log-cabin office in a
quiet spot for creative thinking at College Park.
His Air-Cushion Patents.
Beardsley has a half dozen patents in the air-cushion field, mostly in the
research and development stages, and presently sufficiently promising that
their future may be very rewarding. He says the present operation is shoestring
size. Beardsley's invention, known as the peripheral jet system, is one of
three types of air-cushioning methods. The air taken in by four 6-bladed
42-inch fans (on the vehicles under military test) is pumped out through jets
located around the outer edges of the vehicle. The air discharges vertically
downward or slightly toward the interior, giving the benefit of jet reaction
plus the pressure lift caused by nearness to the ground. The test vehicles,
which weigh 950 pounds, can carry a load equal to their weight while floating
along aboveground. Steering is by movable vanes in the main jets. Hot-rodders
would love this: the driver can turn around and around in a "parked"
position. The military test vehicle never gets more than 15 inches above the
surface, and already has shown ability to skitter over rougher terrain than the
developers had expected. Says Beardsley modestly: "This one is still in
the pre-model-T days."
Two Other Types.
The two other types of air-cushion vehicles are air-bearing and plenum chamber.
In the air-bearing type, which requires smooth, highly prepared surfaces, air
is forced out of small openings at extremely high pressure. This would elevate
the vehicle very slightly, perhaps a six-thousandth of an inch. Such a method,
Beardsley said, would be employed by vehicles running on tracks at speeds of
200 to 300 miles an hour. Plenum chamber refers to a space in which the air is
under a pressure higher than it is on the outside. In vehicles of this type
(such as Curtiss-Wright is developing) air is pumped into a chamber under the
vehicle, and pressure builds up enough so that the air flows out all the way
around it. Beardsley believes the air-cushion boat has a great future. His
development prototype, a scow-like vessel 12 feet Long with a 5-foot beam, is
powered by a 5 h.p. outboard motor. The craft is made in such a way that it
rests on an air cushion sealed by contact with the water on both sides and in
front. "It's a real thrill to see this in action," Beardsley said.
"We poke along about six miles an hour until we turn on the pump that
builds up the air cushion. Then suddenly we raise up off the, water and we're
scooting along at 20 miles an hour at no change of engine speed." Mr. and
Mrs. Beardsley have two children, Susan, 13 and John, 10. Mrs. Beardsley, the
former Marie Stimson of Los Angeles, was a niece of the late Henry L. Stimson,
former Secretary of State and Secretary of War.

Beardsley's Early Years in ACV Development:
It's difficult to establish exactly when Mel. Beardsley conceived the air-cushion vehicle, but he worked on a Navy hydrofoil project in southern California about 1950, and this was his first known involvement in marine vehicles. The air-cushion may have been a low-friction boat-hull solution, to which Beardsley added forced air as the missing element for the basic air-cushion vehicle. It is certain than Beardsley and the British inventor Cockerell conceived the air-cushion vehicle independantly. There was no way that they might have known of eachothers work. One may say that "the idea was in the air."
Beardsley's further personal research led to his patents of the early 1950's. After completing another 7 years of military service, Beardsley founded National Research Associates, Inc. (NRA) in College Park and Laurel, Maryland to build practical air-cushion vehicles.

NRA was founded in 1958 by Mel Beardsley and an Air Force colleague, Bill Alper, in College Park, Maryland. He had sunk his inheritance into financing this company, and for five fruitful years, NRA produced a large variety of air-cushion vehicle prototypes at their Laurel shop, and a few civilian and military product lines as well. Alper was the President, while Beardsley, owner of the patents, prefered to concentrate on the creative role. The photos, articles and promotional materials shown below will give an idea of the breadth of their endeavors.

A single seater, stripped. Its shell can be seen in the background. This
model was called "The Flying Saucer."
An early use for a similar single-seater (but not self-propelled, being inflated by blowers below the deck) was a ride at Disneyland in Anaheim, California. Disney licensed the technology from NRA. Below is a photo of that popular ride, and an NRA promotion of a similar ride as imagined by Beardsley and an artist.


In the above center can be seen the GEM-Jr., a single seat prototype for
land-only conveyance. The name GEM is derived from the acronym for
ground-effects machine. The GEM-Jr. is enlarged below.

By 1961, more mature and practical amphibious vehicles had come into production at NRA, as shown and described in the pictures and articles below.

The Aqua-GEM, of which a few dozen were produced and sold.

The stylish model (essentially a longer Aqua-GEM) shown above did not make it to production. Two articles about the launch of the Aqua-GEM line appeared in local newspapers. These are reprinted in full below:

Amphibian Vehicle Riding On Air Cushion Is Shown
by Albert Sehlstedt, Jr. [Sun Staff Correspondent]
Bay Ridge, Md., Aug. 2 An amphibian vehicle that can cruise-above the waves,
skim over seaweed and drive up a sandy beach was demonstrated here today by a
Laurel (Md.) company. The craft, called an Aqua Gem, rides on a cushion of air
and moves forward with the thrust of a large propeller mounted above the stern.
Someday the Aqua Gem might be used for family transportation by people who want
to avoid crowded highways. A nearby river could be negotiated easily by this
kind of automobile. This air pressure causes the Aqua Gem to rise a few inches
above the water, Mr. Alper said. The Aqua Gem was designed and built by
National Research Associates, of Whiskey Bottom road, Laurel, a company that
has developed similar vehicles for evaluation by the armed forces.
Civilian Use Possible
Although today's demonstration was primarily for the Maritime Administration,
the Marine Corps and the Office of Naval Research the company believes the
machine could be used profitably for civilian purposes, such as ship-to-shore
transportation and commercial fishing in shallow waters. William H. Alper,
President of National Research Associates, explained how the Aqua Gem works.
Two large fans in the bow of the craft blow air down around the periphery of
the boat's bottom.
Inventor Is Official
The stern-mounted propeller, powered by a 50-horsepower engine, drives the boat
forward. Each fan in the bow is powered by a 20-horsepower engine, according to
M. W. Beardsley, vice president of the company and the inventor of the Aqua
Gem. Five rudders, side by side and directly aft of the stern propeller, guide
the craft. Such air-cushioned vehicles are called ground-effects machines;
hence the word "Gem" in the title of this particular version. In
today's demonstration, Alfred G. Anderson, a company engineer, operated the
boat near the shoreline of this Chesapeake Bay community. Mr. Anderson drove
the boat several hundred yards up and down the water, parallel to the beach.
Then he turned the craft toward the land. The vehicle rode right up on the
sand, coming to a stop only when Anderson cut the engines. Thick seaweed
immediately below the water's surface did not seem to hamper the craft in any
way. Mr. Beardsley said the boat will move in the water without employing the
ground effect or air cushion, but it will move very slowly. When the air
pressure raises the hull out of the water the craft can reach a speed of about
40 miles an hour. The inventor said the Aqua Gem model used today is a
prototype 28 feet long and 9 1/2 feet wide. The water vehicle can carry a load
of 1,500 pounds, he said. Mr. Alper said the company is producing the Aqua Gem.
Twelve of the craft have been sold to industrial users, he said. (end of

Produced at Laurel
Jet-Age Boat Tested on Bay
A watercraft geared strictly for the jet age got a workout this week before
both civilian and high ranking service officials at Bay Ridge, Md. The craft is
one of the Aqua GEM line being produced by National Research Associates at
Laurel, Md. Its chief attribute is the fact that, riding entirely on a cushion
of air and propelled by two powerful fans mounted in the stern, it can skim at
high speed over shallow waters, marshes or mud banks. If the water gets too
rough, it even can skim ashore, still supported on its air cushion. It also can
operate as any conventional vessel would, without support from its cushion of
air, but still propelled by the twin fans. Three Models in Line One model was
displayed by National Research at the Chesapeake Boat Show in Baltimore this
spring. Now there are three, the Air Liner, which can carry 10 persons, the Air
Carrier, a cargo craft, and the Air-Sport, for the yachtsman. All are of
futuristic design and each has two 40-horsepower, water-cooled, two-cycle
engines that force air through jets in the hull to raise the boat on its
cushion of air and an 80-horsepower, water-cooled, two-cycle engine that powers
the fans that provide propulsion. The Air Liner is a fully-enclosed hardtop
with center hinged doors, molded fiberglas passenger seats and complete
soundproofing. It is designed for commuters, sightseers and general water taxi
service.
Air Sport a Yacht
The Air Carrier has a cutaway hardtop roof for the crew area, which seats two,
and a cargo space 8 feet wide and 12 feet long. The Air Sport is fitted out as
a yacht with galley that includes a two-burner alcohol stove and sink, head and
foam rubber berths for four. All hulls are 30 feet long with a beam of 9 feet,
6 inches. The armed forces are interested because air-cushioned boats may
provide much speedier landing ,craft than the LCVP's of World War II. National
Research says its models cruise at 40 miles per hour and can do 50. A somewhat
similar craft, the Hydrokeel, made by the Anti-Friction Hull Corp., also of
Laurel, has an $89,000 contract with the Navy. National Research says its boats
differ by being propelled entirely above the surface of the water while others
use propulsion systems that must make contact. National Research also has
designed a 70-passenger, 75 mile-per-hour turbine-powered model which may be
used at the 1964 World's Fair in New York. It envisions providing fairgoers
with a spectacular 10-minute ride from midtown Manhattan right to the Flushing
Meadows fairgrounds. (end of Evening Star article)
The next year seemed full of promise, as indicated in this article:
from the New York Times, June 15, 1962
Craft is Designed for Cushion-Air (sic) Trip to World's Fair
By STACY V. JONES - Special to the New York Times
WASHINGTON, June 15 - A Maryland manufacturer of air cushion vehicles hopes to
build a ferry on which Passengers can glide between Manhattan and the New York
world's fair grounds in 1964 and 1965. A patent for the new craft will be
issued next week. The inventor is Melville W, Beardsley, vice-president of
National Research Associates. Inc., of Laurel, Md. The company has built a
score of vehicles that ride on air, and regards itself as the leading
manufacturer in the field. The proposed ferry has been discussed with world's
fair officials. The manufacturer has also suggested to the Port of New York
Authority the use of air cushion emergency vehicles at the airport.
Next week's patent (No. 3,039,550) covers a new principle called conformal
flow. Under the vehicle is a "plenum chamber" like the inside of an
inverted bathtub. Fans force air downward past baffles and around the inside of
the shell against the water or ground.
Mr. Beardsley invented "peripheral jet" system of air lift eight
years ago. His patent application for this is involved in an interference
action to determine whether he or an English rival was the first inventor. The
other claimant is Christopher S. Cockerell, holder of a British patent for the
Hovercraft.
National Research Associates has built air-lift vehicles for the Army, Marine
Corps and amusement parks, and is now offering three models of its Aqua-GEM for
use over water. Since it can move onto the beach, the craft requires no
mooring. Prices start at $17,500. These "boats that fly" are built
with peripheral jets, which require considerable ducting. Advantages claimed
for the conformal flow design are simplicity and the elimination of the ducts.
The Army Surgeon General is evaluating the National Research Associates
air-cushion litter, of which nine were made under contract. A motor inflates
the litter and lifts it off the ground so that one stretcher-bearer can
maneuver it.
The company was organized in 1958 by Mr. Beardsley and William H. Alper, the
president. It sold stock publicly in 1960. A Denver small business investment
company recently announced an investment of $60,000 in the subsidiary that
makes the Aqua-GEM. One current product is an amusement ride "The
"Flying Saucer" at Disneyland was made inder license from National
Research.

Some military prototypes were developed for the US Army:


An air-cushion litter for transporting wounded soldiers.
Alas, the hoped-for military contracts were not forthcoming, the cash dried up, and NRA closed its doors in 1963.
A patent dispute had developed in the early 1960's to determine who had
first come up with the ACV-hovercraft concept, Cockerell or Beardsley. Many
factors are involved besides mere truth. Beardsley's company was in a
cash-crunch, and his lawyer betrayed him by witholding vital proofs for the
payment of fees. Ultimately Cockerell payed a settlement of $70,000 to
Beardsley for his rights.
Beardsley Air Car Company and Skimmers, Inc.
Mel Beardsley was now without a job, but had a suitcase full of designs. One of the prototypes NRA made also came home with him -- the "Little Skimmer." It was a very basic solo ACV which could get up to a harrowing 15 MPH. It was tricky to master, and took great balance! He established successively two companies in his home, Beardsley Air Car Company and Skimmers, Inc., and set out to see what market there was for sports model ACV's.

Maryland.

Beardsley's son John has less success at getting to speed.
One of the wackier applications was "The Flying Carpet," dreamed up by a carpet manufacturer. This was described in a trade publication below.


Beardsley also single-handedly built a more advanced model in his home basement, as described in the local newspaper article below:
from The Maryland Gazette, 10 Dec, 1964
'The Little Skimmer' From Fairwinds
Unique Amphibious Vehicle Rides On Cushion Of Air, Goes About 20 MPH
by ARLENE SOUTHERN. An amphibious vehicle that rides on a cushion of air.
No wings, wheels, or boat or such type bottom supporting it is under completion
in Col. Melville W. Beardsley's garage at 40 Windward Drive, Fairwinds, Severna
Park. "The Little Skimmer," as Beardsley calls it, rises about 15
inches off the ground (measuring from the framework to the ground) with a
passenger and travels with equal success over pavement, mud, sand, water, ice,
and rough terrain.
What purpose does a vehicle like "The Little Skimmer" serve? It could
serve a myriad of purposes in transportation and in play, but Beardsley is
concentrating on the latter. He sees these little vehicles as a substitute for
the formerly popular go-carts. They have great possibilities especially because
they are amphibious and give an interesting sensation. Also they are in keeping
with the space age, and seem to be erally intriguing to young and old, said
Beardsley. Because of their great versatility - their potential ability to go
faster than boats and their present ability to ride on both water and land -
Beardsley thinks machines like the "skimmer" will eventually "be
a substantial replacement for popular boating."
For persons who want to get away from the incerased highway traffic or take a
vacation, particularly in the sporting vein, the "skimmer" could
offer a practical alternative. Many places not accessible by boat, car or
plane, are accessible to the "skimmer," because it can travel over
almost any surface.
"The automobile used to be a Sunday afternoon affair too, and look what it
has turned into," said Beardsley, emphasising the "skimmer's"
potential. "
The little Skimmer" works on a principle long under experimentation in
Britain, and also by the armed services and some private companies in the US.
In the "skimmer," air is drawn in from above the vehicle by a fan,
which is placed horizontally beneath the body. This fan directs the air
forcefully under the vehicle and towards the ground, thus producing the
elevation. To provide forward motivation, the air is directed toward the rear
of the vehicle. The body of the "skimmer" is about the size of a
go-cart. From underneath the four corners of the rectangular body, four
aluminum pipes extend outward in an "X" shape to a large oval
framework (also aluminum pipe), surrounding the body. Vinyl coated Nylon
fabric, stretched over the ramework and hanging 15 inches below the framework
when the machine is elevated, confines the airflow to the space immediately
below the skimmer. This enables the "skimmer" to rise and move on a
cushion of air. The nylon fabric which hangs from the framework is called a
"skirt,"and almost touches the ground when the machine is elevated.
The "skimmer" is 11 feet long and eight feet wide. However, Beardsley
has made the vehicle collapsible so that, when taken, apart, no one piece is
longer than five feet. It weights 75 pounds, can easily be carried by two
persons and will fit into the back of a station wagon.
This is not the first "hovering" machine Beardsley has made. In
September he completed the last of three "flying carpets," vehicles
similar to the "skimmer," which hover 15 inches above the ground, and
which he was commissioned to make by the Chemstrand corporation in New York
City. The "flying carpets," are the only vehicles of their kind, to
Beardsley's knowledge. The Chemstrand people covered the vehicles with carpets
made with their fibers and used them for advertising purposes. The "flying
carpet," explained Beardsley, differs from the "skimmer" in that
the latter is more of a vehicle.
The "skimmer" has a definite forward pull and although he has not yet
tested it estimates indicate that it will go over 20 miles per hour. In
contrast, the "flying carpet" has no forward motion, it just hovers
over the ground. Forward movement is slow and is facilitated by the operator
leaning forward. Steering on both the "skimmer" and the "flying
carpet" is by kinesthetic control, that is, by the operator leaning in the
direction he wants to go. Because the vehicle is frictionless, it is slippery
to control. Sharp turns are impossible, because the vehicle would skid. To make
a successful turn, the operator has to get up enough speed in order to make the
air controls more dynamic. Like a bicycle, Beardsley said, balance depends to a
degree on speed. With speed, inertia will take the skimmer through a turn.
One possible disadvantage to the present "skimmer" is that it has
difficulty getting up long hills. Small ditches or bumps in the ground do not
affect its performance, but large and especially long hills require such a
large force of air, that it is difficult for the skimmer to climb them.
A five horsepower, two cycle engine powers the fan. Beardsley makes his own
fans for these machines because he can not find one manufactured that is light
weight, strong and that runs at a high rate of speed. One half gallon tank of
fuel, a mixture of gasoline and lubricating oil, said Beardsley, will run the
"skimmer" for one half hour. And if the "skimmer" runs out
of fuel while on the water, the operator can relax.
The vehicle is equipped with a structure like an air raft that inflates when
the machine starts, stays inflated whether the machine is in operation or not,
until the operator lets the air out.
Right now, Beardsley is considering starting a business with the
"skimmer." Quite a few persons are interested and enthusiastic over
prospects of using the vehicle especially on the water. Some see possibilities
of success in the amusement ride line. Beardsley helped Disneyland develop an
amusement ride using vehicles similar to the "skimmer," but the
vehicles at Disneyland are controlled and powered by fans which blow air up
from the floor, so all of the vehicles could be started and stopped at once.
This is reportedly the most popular ride there, said Beardsley.
If he could produce the "skimmers" in quantity, said Beardsley, he
could sell them for $400 to $450 each. Otherwise, it would cost $800 or $900 to
produce only one. At first, said Beardsley, production would be limited. By
subcontracting persons to make the basic parts and putting the parts together
himself, he probably could produce about four "skimmers" per month.
But the "skimmer" business hasn't started yet.
Presently, Beardsley is a consultant to various companies on the feasibility of
a generation of new products. Most of the testing and work on the
"skimmer" has been done in his garage during his spare time.
"When I operate it outside, it attracts so much attention I can't work.
Children gather around to watch and it even stops traffic," he said. He
might move his work into a shop, Beardsley said.
In 1958, when he was working with National Research Associates, the company
built over 20 man-carrying hovering vehicles, carrying from one to six
passengers. This was more than any other company working for the government had
built at the time. Many larger passenger carrying vehicles operating on the
same principle as Beardsley's vehicles have been constructed by researchers in
Britain and the US. Britain has done extensive research with hopes that these
vehicles might eventualy replace ships.
Two years ago, the British ran a 24 passenger ferry service across the Dee
estuary in Wales with a hovering type vehicle. The trip, which takes two and a
half hours by rail or highway, took 30 minutes in the experimental vehicle,
according to George P. Miller in an article in "Saturday Review,"
Dec. 1, 1962. Hovering or "ground effect" machines, as they are
sometimes called, might also speed up transportation of goods on the
Mississippi River and other internal waterways, wrote Miller. The government is
experimenting with small "ground effect" machines to carry injured
men from combat. Ordinarily would take four men to carry an injured man from
combat on a stretcher. A ground effect machine would only require one operator.

Little Skimmer, model 2, drawings and specifications. Thankfully, a seat was
added in the finished model.
These small solo vehicles were relatively slow. Rather than add an extra engine and fan facing the rear, as in the larger Aqua-GEM, Beardsley conceived a single-engine, single-fan design which was a forerunner of modern sports hovercraft. His original dated design sketch is shown below.

After some more time and work in his basement-shop, Beardsley completed his first working "Fan-Jet Skimmer" and he and a friend tested it on the Severn, as seen in the photos below.






Financial backing was not found to begin production, but Col. Beardsley sold a few hundred sets of plans for $15 each. By 1967 he gave up on the idea of starting his own ACV empire, and went to work at the Naval Ship Research and Development Laboratory near Annapolis, Maryland. Again he was working on ACV's, an early one of which is shown below on the Severn near the Lab.

The work he performed at the labs was classified, but it is safe to assume that Mel Beardsley had much input on the huge ACV landing craft currently in use by the US Marines.

Col. Beardsley at his desk at the Naval Lab, about 1970.
He retired from the lab in 1980 and moved with his wife Marie to Carmel,
California. In his retirement he invented, tested, and patented the
Beachbuilder system of beach erosion prevention.
Col. Melville Beardsley passed away 26 November, 1998.
Mel Beardsley was an exceptional engineer with a broad-ranging intellect. History will judge if he should be credited as the true inventor of the Air-Cushion Vehicle, aka the Hovercraft. Those of us who were privileged to know the man acknowledge him for being the very finest gentleman in all respects.
I still have a few boxes of material to sift through, so this site may be updated soon!
Thanks for your attention!
