The D-436TP turbofan features a three-shaft configuration with minimum number of bearing supports. It has a modular design. The transonic fan is of a single-stage type. The low-pressure compressor has six stages, and the high-pressure compressor has seven stages. The engine has an annular combustion chamber.
The lowpressure turbine is single-staged, and the highpressure turbine is three-staged. The engine is equipped with a thrust reverser, an electronichydromechanical control system and universal attachment fittings.
The D-436TP turbofan engine is designed for the Be-200 aircraft. It boasts high reliability ensured by a longtime operating experience of the D-36 engine. It is easy to maintain, and can be operated in sea environment. The engine demonstrates stable operation in spite of sharp air inflow temperature inversions during forest fire-fighting missions. The engine complies with standing and future ICAO noise and emission requirements.
