de Havilland DHC-2 Beaver and Turbo Beaver

DESIGN PHILOSOPHY:     Designed to be operated as a "half-ton truck" in Canada's northern bush areas, the Beaver is an extremely versatile aircraft and has been used in a wide variety of roles, both civil and military. It can be converted for use on floats, amphibious gear, skis and wheel/skis, as well as on standard wheels.

Several new concepts were pioneered with the Beaver:

  • STOL (Short Take Off & Landing)  the idea of clearing a 50 ft obstruction in approximately 1,000 ft horizontally for both takeoff and landing
  • All-metal construction (new for "bush" aircraft)
  • Full-span flaps (Single slotted flaps; ailerons "droop" as flaps are extended)
  • "Rubber-in-compression" shock absorbers for the main landing gear

The last 60 aircraft were built as Turbo Beavers, fitted initially with PT6A-6 engines (500 SHP) and later retrofitted with PT6A-20's when production of the -6 ceased. The Turbo Beaver has a 28 inch "plug" in the fuselage ahead of the wing, thereby permitting 7 seats in the cabin instead of 5.
