Study Objective:

Explain processes of energy transformation in aircraft piston and turbine engines and describe in detail a course of thermodynamic state of working gases and fuels during their through-flow in both piston and turbojet engines. Understand a function of flow engines, particularly axial-flow and centrifugal flow compressor and axial-flow turbine and this both from the point of view of internal aero-thermodynamics and also from the point of view of operational characteristics. Understand function of combustion chamber, formation of the air-fuel mixture, combustion and its operational characteristics. Get up design thermal and construction schemes of turbojet engines, their thermal cycles for given design flight operation mode, realize a layout of the air and combustion products passage of the turbojet engine on the main flow streamline and calculate its operational characteristics. Understand the coactions of all of the jet engine construction modules and get oriented in its operation characteristics. Understand operation of the turbojet engine in off design flight regimes and understand the function of automatic control of the turbojet engine.
