PZL-130 Orlik
The PZL 130 Orlik ((英語:Eaglet)) is a Polish turboprop, single engine, two seat trainer.
==Development and design==
The Orlik was designed by PZL Warszawa-Okecie as a trainer for the Polish Air Force, intended as a replacement for its PZL-110 Kolibers. It was also designed to meet the American FAR 23 standard. The project was under the supervision of Andrzej Frydrychewicz, head engineer of PZL Warszawa-Okecie. It was fitted with a low-aspect ratio wing to better simulate the handling characteristics of jet fighters.〔''Air International'' October 1985, pp. 167–170.〕 The aircraft was designed to be powered by a Soviet-designed and built Vedeneyev M14Pm radial engine with the intention of replacing it by a modified Polish built Ivchenko AI-14 engine in production aircraft.〔''Air International'' October 1985, p.170.〕 The first prototype Orlik flew on 12 October 1984, with a second prototype following in December and a third in January 1985.〔
While the Polish Air Force planned to power its Orliks with locally produced radial engines, PZL planned a turboprop powered version, the PZL-130T Turbo Orlik for export purposes.〔''Air International'' October 1985, p.172.〕 The third prototype was therefore re-fitted with a 410 kW (550 shp) Pratt & Whitney PT6A-25P turboprop, flying in this form on 13 July 1986, but was destroyed in a crash in January 1987 while being demonstrated to a representative of the Colombian Air Force.〔Taylor 1988, pp. 195–196.〕 Two further turboprop prototypes followed in 1989 and 1990, powered by a Czech-built 560 kW (750 shp) Walter M-601E and a PT6A-25 as the PZL-130TB and PZL-130TP respectively.〔Lambert 1993, p.246.〕
In 1990, development of the piston-engined Orlik was abandoned, as the Polish built radial engines gave insufficient power, with Polish interest switching to the M-601 powered PZL-130TB.〔
