The SZD-26 Wilk (Wolf, SZD standing for Szybowcowy Zakład Doświadczalny, or Experimental Glider Department) was a projected two-seat motor-glider designed in Poland
in 1961. A unique design in many aspects, it never entered serial production.
motor glider
with a pusher propeller and the engine located in the rear of the central nacelle
which also housed the tandem cockpit. The tricycle undercarriage
was designed to retract rearwards into the nacelle, under the cockpit and either side of the engine. The two-bladed propeller was designed to stop when level with the wings to reduce drag with the engine off. Lack of a suitable powerplant stopped further work on the SZD-26 Wilk.
