IPE Quero Quero

  This Brazilian single-seater training glider, known in full as the IPE KW 1 b 2 Quero Quero II, is a development of the original KW 1 designed by Ing Kuno Wiedmaier and made its first flight on 1 October 1972. Certification ДальшеMore>>> from the Brazilian CTA in the semi-aerobatic category, with an extension for cloud flying, was awarded in December 1976 and the Quero Quero II was put into production by IPE - Industria Paranaense de Estruturas at Curitiba in the state of Parana. By 31 March 1979 IPE had completed 28 Quero Queros, consisting of one static test and three flying prototypes, a pre-series of four production aircraft, one of which was lost in a non-fatal accident, and all of a second-series batch of 20 Mk IIs, which are now in service with various Brazilian clubs. The Quero Quero is a cantilever high wing monoplane with the same Wortmann wing section as the Scheibe SF-30 Club-Spatz, which it somewhat resembles, and is of wood and Brazilian pine plywood construction. There are spoilers in the wing upper and lower surfaces, and the wing tips are turned down to provide an endplate effect. Landing gear consists of a non-retractable monowheel and a tailwheel, and the pilot sits under a one-piece detachable cockpit canopy.

IPE 02 Nhapecam

  The 02 tandem two-seater, known as the Nhapecam, is the second training sailplane from the Brazilian firm of IPE - Industrie Paranaense de Estruturas at Curitiba, and has been under development for some months; it made its first flight on 24 May 1979. The 02 is a cantilever shoulder wing monoplane with a modified Scheibe SF-30 Club-Spatz wing section; it is rather larger than the Quero Quero II, with a span of 16.60m (54ft 5 1/2 in), a longer, more pointed nose and a lengthened one-piece cockpit canopy under which the two pilots sit. There are spoilers in the wing upper and lower surfaces, and the landing gear consists of a non-retractable monowheel and a tailwheel. A powered version of the 02, the IPE 03, is under development; this has a repositioned low wing and a retractable landing gear, and the 60hp powerplant will probably be one of the Limbach SL 1700 range of four-stroke engines that are fitted to several other types of powered glider. An order for at least 30 IPE 02s for the Brazilian Clubs was confirmed in 1980.
