Jancsó-Szokolay M22
The Jancsó-Szokolay M22 was a Hungarian single-seat sailplane first flown in 1937. Twenty were built and the type set several national records. Some remained in service up to about 1953. Design and development In the mid-1930s the MSrE (Műegyetemi Sportrepülő Egyesület) or Aero Club of the Technical University decided to build a sailplane capable of thermal, cross country flights. They began to build a Rhönbussard but Erno Rubik encouraged Endre Jancsó and András Szokolay to design a new, Hungarian aircraft incorporating the Rhönbussard parts already completed. The result was the M22 which flew for the first time on 1 September 1937. The two-part gull wing of the M22 was mounted at mid-fuselage. The central panels were rectangular in plan, occupied about 35% of the span and had 8° of dihedral. The outer panels were trapezoidal apart from rounded tips and had no dihedral. Both panels shared a single spar which, with plywood skinning forward of it around the leading edge, formed a torsion-resistant D-box. The half-wings were joined together within the fuselage. Near the fuselage the plywood extended rearwards to an angled drag strut. The rest of the wing surface was fabric covered. Parallel chord ailerons, mounted on a light
