The SZD-22 Mucha Standard (Szybowcowy Zakład Doświadczalny – Glider Experimental Works) was a single-seat aerobatic glider designed and built in Poland from 1957.
Development
Developed especially for the 1958 World Gliding Championships, the SZD-22 Mucha Standard was a direct descendant of the IS-2 Mucha (Fly), from 1948, and SZD-12 Mucha 100, from 1953, with very similar lines and dimensions. The Mucha Standard was designed to the new Standard class rules which discarded the old Olympic 15-15-15 Span, Aspect Ratio, Area rule.[1]
The first flight of the SZD-22 took place at Bielsko with Adam Zientek at the controls on 10 February 1958.[2] It was followed by the second prototype in June 1958. Flight trials were successful, leading to a long production run with six variants, which introduced various modifications.
Built primarily of wood, the SZD-22 had airbrakes in the wings, a streamline cockpit canopy, short nose and tail skids with a single mainwheel. The SZD-22C model replaced the plywood covering of the wings with fabric and some models had provision for water ballast in rubber bags fitted to the wing roots.[1] Most of SZD-22s – 271, were built in ZSLS in Krosno.[2]
Many SZD-22's, mostly SZD-22C models, were exported to the Great Britain, Argentina, Austria, Australia, Belgium, Denmark, Finland, France, Greece, Yugoslavia, Mexico, Norway, West Germany, Switzerland, Sweden, Tunisia, Turkey, USA, Hungary and Italy[1] Adam Witek flew the SZD-22 Mucha Standard to first place in the Standard class at the 1958 World Gliding Championships at Leszno in Poland.[1]
