The main goals of the subject are the students knowledge obtaining of the work principles, types, main elements, characteristics and usage areas of air-breathing engines. One of the principle goal is establishment of the corelation among the aircraft types and appropriate propulsion systems in order to achieve given aircraft mission goal in optimal way according to the goal functions and existing constraints.
Students are going to achieve the ability to perform decomposition, to analyse and to make synthesis of the propulsion system together with the aircraft. The student gets the knowledge of different types of air breathing engines, and their main energetic components. The knowledge obtained by student is related to the design and determining of the performance of the appropriate engines needed for engine quality estimation. Gained knowledge enables further student professional development in the field of aircraft propulsion.
Thermodynamic cycles and thrust. Propulsion efficiency and basic engine performances. Propulsion circuit and its basic elements. Ideal ramjet, turbojet, turbojet with afterburner and turboshaft engines, ideal turbofans with separate and common nozzle. Real elements of propulsion circuit: intake and nozzle. Compressor and turbine. Mixer, combustion chamber and afterburner. Working lines of turbojet and turboshaft engines. Engine starting. Engine performances: altitude, speed and throttling. Working envelopes of various engine types. Advanced propulsion types. Contemporary problems in airbreathing propulsion and future trends.
Practical parts of the classes consists of examples, analysis and discussion with the students in the areas that are discussed in theory. Thermodynamic cycles and thrust.
