Study Objective:

Make clear of principles of aircraft propulsion from the point of view of a thrust production and energy intensity needed for its provision.

Make clear of principles of aircraft engines functioning focused both on engines with periodic and continuous thermal cycles and familiarize students with their construction schemes and operational characteristics.

Make clear of a process of energy transformations within aircraft propulsion units and their internal (combustion and thermal) and external (propulsive) efficiencies.

Make clear of operational characteristics of aircraft propulsion units, throttle characteristics, speed-power and speed ? thrust characteristics, altitudinal ? power and altitudinal ? thrust characteristics.

Familiarize students with importance of the aircraft propulsion disturbance on environment, particularly noise and pollutant emissions generated by engines and ways and measures of their reduction.

Master the basics of aircraft propellers.
