PWS-102 Rekin

The prototype flew in an international contest in 1939 and the first of a projected production series was flown before the start of World War II.

The gull wings of the PWS-102 were high-mounted, with less (5°) inner dihedral than on its predecessor and tapering outwards in both chord and thickness out to fine elliptical tips.

These surfaces occupied essentially all the trailing edge of each wing, with a pair of differential ailerons outboard and a camber-changing flap inboard.

As on the earlier design, the trailing edges of the latter were ahead of the rudder hinge and the elevators were assisted by inboard Flettner tabs.

[3] After its first flight in March 1939 and some small modifications made during an uncompleted development programme, the PWS-102 competed in the ISTUS International Glider Contest held in Lwów in May.
