Aircraft engine The two-shaft turbofan aircraft engine consists of a two-stage low-pressure compressor manufactured using "blisk" technology (the blades are made integral with disk), an 8-stage high-pressure compressor, an annular combustion chamber, a single-stage LP turbine and a single-stage HP turbine, and a nozzle. The engine has a bottom-mounted accessory gear box. The engine is designed to power the Yak-130 training aircraft.

Aircraft engine and its modifications The AL-31F aircraft engine is a modular two-shaft turbofan engine consisting of the following main parts: a gas generator (comprising low- and high-pressure compressors and turbines), an annular combustor, an afterburner and a nozzle, an accessory gear box and a control system. The compressor portion includes a 4-stage low-pressure module (with adjustable air flow) and a 9-stage high-pressure module. The engine uses a two-stage (HP and LP) turbine with adjustable...

... two-shaft turbofan engine with thrust vector control and integrated digital control. The engine is installed on Su-35-type aircraft. As for geometry and attachment points on the aircraft, the 117S engine conforms to its predecessors, the AL-31F and AL-31FP engines. This makes it possible to use the 117S engine for upgrading the entire fleet of previously built Su-27-/Su-30-type aircraft, with minor engine nacelle and equipment modifications. Engine performance enhancement has been achieved through the use ...

... speed governor and LP turbine exit temperature limiter, surge, ice and fire detectors. In terms of the key indicators characterizing engine efficiency (thrust-rise rate with Mach number, engine weight-to-power ratio, etc), the RD-33 is among the best engines in its class. It provides rapid acceleration from idle to thrust maximum non-afterburning and afterburning settings. The RD-33 is used in a wide range of altitudes and speeds, provides stable operation under extreme conditions. Owing to its high ...
