GYRODYNE YRON-1 ROTORCYCLE<\/h1>\n

\"\"<\/p>\n

\n

The Gyrodyne Rotorcycle was originally designed for the U.S. Navy but was adapted to a Marine Corps requirement for a small one man helicopter that could be used for battlefield observation.\u00a0 The possibility of dropping the Rotorcycle to downed airmen behind enemy lines so that they could fly themselves to safety was also considered.\u00a0 The craft\u2019s first flights occurred in 1955.\u00a0 The program was terminated by 1959 after the Marine Corps determined that the YRON was too heavy and too hard to fly to suit their needs.\u00a0 However the coaxial rotor design, which allows the elimination of a stabilizing tail rotor was of interest to the Navy.\u00a0 This led to the development of the remote controlled QH-50 DASH anti-submarine drone which served for several years on smaller Navy escort ships that could not support a full size helicopter.<\/p>\n<\/div>\n\n\n\n\n\n\n\n\n\n\n
