The Politechnika Warszawska PW-5 Smyk (Polish: "Little rascal") is a single seater sailplane designed at the Warsaw University of Technology (Polish: "Politechnika Warszawska") and manufactured in Poland. It is a monotype World Class glider.
The PW-5 was designed for, and won a competition held by the International Gliding Commission for a simple, low cost sailplane that would form the basis for a new competition class, the IGC World Class. Unlike other soaring competition classes, the World Class designation would guarantee that all pilots participated on an equal footing, and that pilots could not gain advantage by spending large amounts of money. The PW-5 was unanimously chosen from 42 design proposals in IGC international World Class design competition. In November 1989, the IGC issued a worldwide call for proposals. By February 1990, it had received 84 requests for design specifications from 25 countries. By August 1990, the IGC had received 42 design proposals from 20 countries. In September 1990, after reviewing the proposals, many of which came with models, the IGC recommended that 11 designs from 9 countries proceed to the prototype competition. In October 1992, the IGC inspected and tested 6 prototypes from 5 countries at Oerlinghausen Germany. After further review and collecting manufacturing data, in spring 1993 the IGC declared the PW-5, designed by a faculty/student team at Warsaw University of Technology, the first World Class glider.
The glider was designed at the Faculty of Power and Aeronautical Engineering of the Warsaw University of Technology under the supervision of Roman Świtkiewicz. It was originally built by PZL at its factory in Świdnik and first flew in 1993. By the end of 2000 the new private company PZL-Bielsko1 was established by the original members of the design team from Warsaw University of Technology and the DWLKK company. A new factory at Bielsko produced a modified version of PW-5 glider called B1-PW-5.
