The RR500 is a larger derivative of the Rolls-Royce RR300 turboshaft, with the engine core scaled-up for increased power. [1] The basic weight of the engine with accessories is 250 lb (113 kg). The model produces around 500 shp (373 kW) for takeoff and can produce 380 shp (280 kW) in continuous use.
The engine was expected to fly first in mid-2013 on a Van's Aircraft RV-10 testbed, [1] but development ended before the engine was flown. By 2022 PBS Velká Bíteš was offering the TP 100 for sale as the non-certified PBS TP100 Turboprop Engine "for small aircraft and unmanned aerial vehicles".
The turboprop was designed for use on the Let L-410 and the M601 first ran in 1967. It was not suitable for the prototype L-410 and the company developed an upgraded version, the M601A, with a slightly wider diameter.
On July 11, 1989, Saab-Scania A.B. selected the GMA 2100 to power its new Saab 2000, a 50-seat stretch of the Saab 340 turboprop, in a US$500 million deal. [2] In July 1990, Industri Pesawat Terbang Nusantara (IPTN) of Indonesia picked the GMA 2100 as the engine for the twin-engine N-250 regional airliner. [3]
The engine ran about 60 °F (33 °C) hotter than the TPE331-14 in the core. [3] It was Garrett's first free-turbine turboshaft, avoiding the high reduction gear of a single spool turboprop and allowing an easier starting since the gas generator is disengaged from the power turbine. The HP spool turns at 31,500 rpm while the LP spool turns at ...
It will compete with the Pratt & Whitney Canada PT6, produced at 51,000 units and leading the small turboprop market for 50 years, adding to the sub 850 horsepower (630 kW) General Electric H80. It has been selected to power the new Beechcraft Denali single engine turboprop aircraft, seating up to 12 passengers at over 280 knots (520 km/h) for ...
The Navy and Allison signed a formal contract on 2 May 1986, and the first engine to test ran six months after. [7] The T406 is based on the Allison T56 turboprop from the P-3 and the C-130, with the free power turbine of the Allison T701 turboshaft from the defunct Heavy Lift Helicopter program.
