15. Flying Platform, 1956

The Hiller Aviation Museum houses some of the most unique flying machines imaginable. One such craft, the Flying Platform, is the prototype developed from National Advisory Committee for Aeronautics (N.A.C.A.) engineer Charles H. Zimmerman's concept known as the "Flying Shoes". Charles Zimmerman, to the amusement of his engineering peers, proved the theory that rotors on the top (i.e. helicopters) are inherently unstable. Zimmerman theorized a person's natural balancing reflexes would suffice in controlling a small flying machine. Charles coined the term "kinesthetic control," similar to riding a bicycle or balancing a surfboard.
Complementing Zimmerman’s "kinesthetic" theories, the Hiller Advanced Research Division (A.R.D.) incorporated a five foot fiberglass round wing, (ducted fan) with twin counter rotating coaxial propellers powered by two 44hp/4000 rpm, four cylinder opposed, two-cycle, Nelson H-59 Engines. The Nelson engine was the first two-cycle engine certified by the FAA for aircraft use. Utilizing the Bernoulli principle, 40% of the vehicle's lift was generated by air moving over the ducted fan's leading edge. The remaining 60% of lift was generated by thrust from the counter rotating propellers.
Hiller Helicopters, on 17 September 1953 signed a contract with the Office of Naval Research's Naval Sciences Division (ONR) to incorporate Alexander Satin's ducted-fan research with Charles Zimmerman's "kinesthetic" theories. The classified project was turned over to the ARD at Hiller Aircraft, and construction began in January 1954. Nine months later the ARD group, working in complete secrecy, delivered the prototype model 1031 Flying Platform. The first free flight of the Flying Platform took place on 27 January 1955, and went in the record books as the first time man had flown a ducted fan vertical take off and landing (VTOL) aircraft. In April of 1955 the veil of secrecy was lifted and all the world wanted a vectored thrust vehicle for their own.
Hiller Helicopters was awarded a U.S. Army contract in 1956 and produced two larger model flying platforms with the Army designation of VZ-1 Pawnee. These vehicles are similar in design but were 8 feet in diameter, 7 feet high, weighted 180lbs empty and the contract required a third Nelson engine installed. The added weight from the third engine severely affected the pilots' ability to use "kinesthetic" movements for directional control. A modified version of the Pawnee, with a longer duct skirt was designated the VZ-1E, and ended its career at Princeton University as a test vehicle for ducted fan research.
Of the six Flying Platforms that were built, the (ONR) vehicle is on exhibit at the Hiller Aviation Museum, and the National Air & Space Museum has a VZ-1 Pawnee that is on loan to the Pima Air & Space Museum. Both platforms may be viewed on line at their respective web-sites. The location of the remaining flying Platforms are unknown. If you have information regarding the disposition or physical location of other Hiller platforms please contact the museum.

"This invention relates generally to ways and means for propelling a person through the air in a controlled flight. More particularly the invention provides a wingless aircraft propelled by thrust reaction and capable of vertical ascent for take off and climbing, hovering in the air, horizontal flight, and vertical descent under such conditions that directional control, and transition from vertical to horizontal flight and vice versa are effected by body movements or balance of the pilot flying the machine."   (A statement from the Patent # 2,953,321)

The 47-year-old Hiller flying platform, the closest design to mimic a magic carpet still captures the public imagination.
16. Sea Shoes, 1962 
The inventor M. W. Hulton demonstrates his sea-shoes and duckfoot propellers on the Grand Union Canal, England.

17. TV Glasses, 1963 
The first set of TV glasses were invented by Hugo Gernsback in 1963. Hugo Gernsback was an Luxembourg American inventor, writer and magazine publisher, best remembered for the first science fiction magazine, Amazing Stories, first published in 1926. His contributions to the genre as publisher were so significant that, along with H.G. Wells and Jules Verne, he is sometimes popularly called “The Father of Science Fiction”.

18. Cat-Mew Machine, 1963
Also in 1963, another Japanese inventor that his Cat-Mew machine--capable of meowing and lighting his eyes every ten minutes. The device for scaring rats and mice and is powered by a two-watt motor.

19. Portable Sauna, 1962
The photograph above, taken in 1962, is the first example of a portable Finnish sauna that we could find. It was included in Life magazine's round-up of 30 dumb inventions. But a quick Google search shows that they haven't gone out of style. In fact, the Finnish Olympic teams reportedly take portable saunas with them when they leave the country for competitions.

20. Mini Television, 1966 
British inventor Clive Sinclair shows off his mini television. Please note the thickness of his glasses.
