Gyrodyne QH-50

In 1956, Gyrodyne entered the competition to produce a single seat "personal" helicopter for operation off destroyer heli-decks for fleet observation, and for battlefield support, and built ten examples of the XRON-1 for the U.S. Navy. These also had a coaxial rotor layout and a 40hp Nelson H.59 engine - later replaced by a 60hp Porsche. This experiment led to development of the QH-50 unmanned drone versions of the XRON-1 and Gyrodyne delivered over 60 production QH-50Cs for operation from Naval frigates.

I was the project officer on this program at Patuxant River, Naval Air Test Center. To bad it was not a good delivery system for weapons, it was a good flying machine.

Do you have any comments ?
