PZL Mielec TS-11 Iskra
|TRAINER, ATTACK, RECON||Virtual Aircraft Museum / Poland / PZL|
Design of the P.Z.L. Mielec TS-11 Iskra (spark) two-seat turbojet-powered primary and advanced trainer began in 1957, being intended as a replacement for the TS-8 Bies two-seat basic trainer. Four prototypes were built, and the first flight of the type was recorded on 5 February 1960. Following type approval during 1961 initial deliveries began in March 1963, and the TS-11 became operational with the Polish air force in 1964. Since that time well over 500 have been built, manufactured not only for use by the nation's air force, but also for export to India, which procured 50. A cantilever mid-wing monoplane of all-metal construction, the TS-11 has retractable tricycle landing gear and is powered by a single turbojet mounted within the fuselage, aft of the cockpit. Early aircraft were powered by the Polish-designed HO-10 turbojet developing 780kg thrust, but from the mid-1960s TS-11s have been powered progressively by the 800kg thrust SO-1, the similarly rated but improved SO-3, or the uprated SO-3W. The Iskra is currently being replaced in Polish air force service by the I-22 Iryda.
