Allison Model 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995.
Design and development
Allison adopted a reverse airflow engine configuration for the Model 250: although air enters the intake/compression system in the conventional fashion, the compressed air leaving the centrifugal compressor diffuser is ducted rearwards around the turbine system, before being turned through 180 degrees at entry to the combustor. The combustion products expand through the two stage gas generator turbine section, which is connected to the compressor via the HP turbine shafting. The combustion products continue to expand through the two stage power turbine which generates shaft horsepower for the aircraft. A stub shaft connects the power turbine to a compact reduction gearbox, located inboard, between the centrifugal compressor and the exhaust/power turbine system. The exhaust gases then turn through 90 degrees to exit the engine in a radial direction.
