Canadair CL-84-1/CX-84/CX-131 Dynavert.

The Canadair CL-84 Dynavert, designated by the Canadian Forces as the CX-131, was a V/STOL turbine tiltwing monoplane designed and manufactured by Canadair between 1964 and 1972. Only four of these experimental aircraft were built with three entering flight testing. Two of the CL-84s crashed due to mechanical failures, but there were no fatalities in either of the accidents. Despite the fact that the CL-84 was successful in the experimental and operational trials carried out between 1972 and 1974, none of the prospective customers placed any orders for the type.

The Dynavert vertical take-off and landing (VTOL) aircraft was designed in the mid-1960s with its first roll-out in late 1964. The Dynavert incorporated a unique tilt-wing and was intended to be developed for use as a troop transport, ground support, reconnaissance, and search and rescue. It was able to take off and hover like a helicopter, or operate in conventional level flight at 350 mph. The Dynavert was powered by a pair of Lycoming LTC1K-4C turboprops.

The prototype CL-84 (Serial CF-VTO-X) crashed in 1967; CX-8401 crashed in 1973. There are two survivors: CA&SM, Ottawa, Ontario (Serial No. CX-8402). WCAM (Serial No. CX-8403), Winnipeg, Manitoba. Harold Skaarup web page
