SZD IS-2 Mucha
The SZD-22 Mucha Standard Standard Class single-seater had its origins in the IS-2 Mucha (or Fly) intermediate single-seater of 1948, which was produced in several versions and used in some numbers by the Polish gliding clubs; the Mucha-ter set up several national records for altitude and distance, and the type achieved several Diamond C flights. The IS-2 Mucha had a single-spar high wing with an aspect ratio of 15, and was fitted with dive brakes and spoilers; the fuselage was of elliptical cross-section. The Mucha-ter was developed into the SZD-12 Mucha 100 of 1953, this single-seater being used for training. It was of all-wood construction, the cantilever high wings having a single main spar and an oblique auxiliary spar, with a plywood-covered leading edge torsion box; air brakes were fitted and the ailerons were aerodynamically and mass balanced. The oval-section fuselage was plywood-covered and the pilot sat under a onepiece Plexiglas canopy. Landing gear consisted of a monowheel and short front and rear skids sprung with rudder pads.
