Allstar SZD-54 Perkoz
glider aircraft
The Allstar SZD-54 Perkoz (English: great crested grebe) is a two-seater, glider for training, aerobatics, cross country flight and cloud flying from the Polish manufacturer Allstar PZL Glider (formerly PZL Bielsko). The sailplane has exchangeable wing tips for either 17.5 or 20 metres (57.4 ft or 65.6 ft) and is manufactured primarily from glass fibre reinforced plastic (GFRP). Without wing extension, it is certified for unlimited aerobatic manoeuvres. For glider training, the short wingspan (17.5 metres) is supplemented with winglets. As a cross-country glider with a 20 metres wing and winglets, the Perkoz has a glider index of 102. The SZD-54-2 Perkoz is the successor of the widely used SZD-50-3 Puchacz trainer, which is part of the SZD family of aircraft.
Design
The SZD-54 was designed in 1991 by Adam Meus as a universal sailplane for flight training and aerobatics, and is certified to European Aviation Safety Agency (EASA) CS22 standards. It is designed as a replacement for the SZD-50-3 Puchacz, a two-seater training glider from 1979, which Adam Meus also led the design.
The sailplane can be purchased with 3 wing configurations: 17.5-metres wingspan with simple wing tips for aerobatics, 17.5-metre wingspan with attached winglets for training flights, and 20-metres wingspan with attached wing tips and winglets for cross-country flights. Despite its fixed landing gear, the SZD-54-2 has a best glide ratio of 42:1 with the 20 metres span wing and offering a glide ratio of 38:1 with the 17.5 metres.
