A nose fan supplied air to the air cushion contained within the peripheral curtain around the 8 ft. diameter platform. Ground Effect Machines are very successful and are used as ferries to carry cars and passengers across the English Channel./nFan Diameter 2 ft Peripheral Diameter 8 ft. Speed 10 mph.../nhttp://www.transchool.lee.army.mil/museum/transportation%20museum/gem2.htm/nTHE PRINCETON GEM Between 1959 and 1962, the Army agree to help fund ongoing testing of a ground effects machine (GEM) which had been developed by Princeton University. At that time the U.S. military had to type-classification for aircushion vehicles, and this became known simply as the Princeton GEM./nThe saucer-shaped GEM was constructed of steel tubing and aluminum ribs and covered with fabric. It was 20 feet in diameter. The aircushion was created by a main vertical-lift engine which drove a horizontally-mounted four-bladed wooden propeller. The propeller drove air downward through a 19 foot nozzle in the saucer's bottom to create a peripheral air curtain. A smaller engine and propeller in the horizontal tailfin provided forward propulsion. Though never produced by the Army, the craft provided a wealth of information about the mechanics of air-cushioned flight.
