Canadair CX-131 DYNAVERT

The unique Canadair CL-84 Dynavert was started as a company private venture in response to NATO specification. The NATO requirement provided for a transport, reconnaissance, SAR and ground support aircraft that could take-off vertically, perform short take-off and landings (STOL).

Canadair's response was a relatively conventional appearing design which featured a wing, complete with turboshaft engines powering large 14 ft (4.3 m) diameter rotors, that could be tilted upward through100 degrees. The tailplane and twin vertical stabilizer's also pivoted and the most unconventional feature were horizontally mounted contra-rotating tail rotors.

This overall unique design foreshadowed the much later successful "tiltrotor" designs by Bell / Boeing. However, despite successful VTOL demonstrations by the prototype and by three subsequently improved trial aircraft, the Canadair Dynavert never achieved production status. The aircraft had been accepted by the Canadian Armed Forces for the trials and were also subject to extensive tests by the US Navy and Marine Corps. The Canadair aircraft helped pioneer the feasibility of the "tiltrotor" concept but unfortunately proved to be ahead of its time.
