газотурбінний двигун, вологовміст, математична модель, осьовий багатоступеневий компресор, Motor vehicles. Aeronautics. Astronautics, TL1-4050

The mathematical model of a turbo-shaft engine with a two-stage gas generator was obtained. This model is based on the multi-stage compressor blade – to - blade description, which makes it possible to evaluate the effect of air humidity on its performances. The characteristics of the axial multistage compressor in the presence of a moist component in the air at the engine entrance and in its absence were compared. The gas turbine engine main parameters were shown in the presence of moisture content. The quantitative estimation was made as well.
