One of Allison's most successful projects is the Model 250 turboshaft/turboprop engine family, which was started by the company in the early 1960s, when helicopters started to be powered by turbine, rather than reciprocating, engines. Allison turbine engines were used to power Bell 206 Jet Ranger and Long Ranger helicopters as well as the ...
Early models were powered by a Rolls-Royce-Allison Model 250-C18 gas turbine producing a claimed 320 hp (240 kW) at 52,000 rpm. [3] Unlike some turbojet-powered motorcycles which relied on jet propulsion for thrust, the Y2K Superbike's turboshaft engine drives the rear wheel via a two-speed gearbox and chain and sprocket. The motorcycles are ...

During the 1990s, some Bell 222s were modified with the 222B's engines and 230's Allison 250-C30G engines for improved single engine (engine-out) performance, and redesignated as 222SPs. [6] Bell 430 In 1995 the Bell 430, a stretched 230 (adding another seating row), was launched, with uprated engines and a four-blade main rotor.

The RR300 is the second attempt to develop a lower-rated version of the Model 250, coming 20 years after the 350 shp Allison Model 225 of 1987. [ 2 ] The five-seat Robinson R66 light helicopter features the RR300 as a turboshaft engine, Robinson having originally intended on utilizing the standard Model 250-C20.
Other differences compared with the MD 520N include a new six blade main rotor (the MD 520N has a five blade unit) and an uprated Allison (now Rolls-Royce) Model 250 turboshaft. The prototype was modified to MD 600N standard with a production standard engine and tail boom and flew in November 1995, followed the next month by the first MD 600N ...
