PZL Bielsko SZD-59 Acro is a glider manufactured in Bielsko-Biała near Państwowe Zakłady Lotnicze (PZL, German State Aviation Works).
History and construction
The fuselage of the SZD-59 comes from the PZL Bielsko SZD-48-3 Jantar 3 , as do the wings, which, however , have been shortened for this aerobatic version . To ensure stability for aerobatics, individual components such as the supporting structure and the cross tail were reinforced. For cross-country flights, 150 liters of water can be carried as ballast to increase the wing loading. This means that the glider is fully suitable for aerobatics and can be converted into a long-distance glider in just a few simple steps. The first flight took place on September 9, 1991 and so far two prototypes and 23 production aircraft SZD-59-1 have been built.
