... 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 ...

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 ...
