that was designed and built at the Warsaw University of Technology and also produced by DWLKK in the early 1990s. Total number of 19 gliders were built, including variant PW-2D bis.


Design and development

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. The aircraft is made from composite material, with its control surfaces covered in doped
aircraft fabric covering Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as ar ...

Operational history

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.
