SZD-12 MUCHA 100

The SZD-12 Mucha 100 (Szybowcowy Zakład Doświadczalny - Gider Experimental Works) was a single-seat glider aircraft that was designed and built in Poland from 1953. The SZD-12 Mucha (Fly) 100 was derived from the IS-2 Mucha ter for use by aero clubs throughout Poland. Two hundred and ninety were built with 73 exported to several countries, and an unknown number were licence-built in the Peoples Republic of China (PRC). Constructed from wood/plywood throughout, the Mucha 100 was much improved from the IS-2 Mucha, with smoother surfaces, better aerodynamics and comprehensive instruments and equipment including a KF-18 oxygen system, lighting and instruments for cloud flying. Pilot comfort was improved by slightly reclining the seat back and increasing legroom, and visibility was increased through a larger one-piece cockpit canopy. Schemp-Hirth style airbrakes replaced the DFS style airbrakes of the IS-2, external mass balances fitted to the ailerons cured the tendency to flutter. The wing incidence was reduced to 2° to better align the fuselage with the airflow at higher speeds, reducing drag. Main designer was Władysław Okarmus, constructors were Jan Dyrek and Zbigniew Badura. The prototype was made in ZSLS No.5 in Krosno - it was the only prototype of the SZD design that was not made in the SZD works in Bielsko. Flight trials commenced on 14 November 1953 in Krosno (first flight by Adam Zientek) and soon revealed a dangerous tendency to flutter, in part due to a lack of control surface mass balancing. After balancing of the ailerons and tail surfaces, as well as other improvements, the Mucha 100 was cleared for production as the SZD-12 Mucha 100. Production started in 1954 and 256 were made in ZSLS in Krosno, 14 in Gdańsk and 20 in Wrocław. Further improvements were incorporated into the SZD-12A Mucha 100A, which had the external mass balances replaced by weights in the leading edges of the ailerons forward of the hinges. Another modification which was also applied retrospectively to earlier units was a re-located mainwheel, moved rearwards to reduce the weight on the tailwheel during ground handling. 70 Mucha 100's were exported, mostly to the USSR, DDR, Italy, Switzerland and China in multiple orders; single examples were also exported to Austria, France, Finland and India.
