The Politechnika Warszawska PW-2 (English: Warsaw Polytechnic PW-2), also called the PW-2 Gapa, is a Polish lightweight high-wing, strut-braced single-seat, glider that was designed and built at the Warsaw University of Technology and also produced by DWLKK in the early 1990s.[1][2] Total number of 19 gliders were built, including variant PW-2D bis.[3][4][5]

Design and development[edit]
The PW-2 was designed as a lightweight glider of modest performance with an open cockpit. The aircraft was intended to be produced as both a completed aircraft and as a kit for amateur construction.[1]
The aircraft is made from composite material, with its control surfaces covered in doped aircraft fabric covering. Its 11.0 m (36.1 ft) span wing employs an American-designed NACA 4415 airfoil. The maximum glide ratio is 16:1 at 69 km/h (43 mph)[1][6]
Operational history[edit]
In August 2011 five PW-2Ds were registered in the United States with the Federal Aviation Administration. All were in the Experimental - Exhibition/Racing category and all produced in 1992 or 1993.[2]
