Abstract This chapter handles turbine-based engines (turbojet, turbofan, and turboramjet). This chapter starts with historical prospective and a classification of each engine. Next, thermodynamic and performance analyses for ideal and real cycles are introduced. Turbojet engine was coinvented in the 1930s by British and German activities. Analyses of single and double spools in the presence and absence of afterburner are described. Though rarely used in airliners or military planes in present days, it is still used in micro-turbojets and turbojets powering rockets during sustained flight. Turbofan engines are continuing its superiority for most present commercial airliners and military planes as well as some rockets for sustained flight. Unique classification of the numerous types of this engine based on fan location (forward/aft), bypass ratio (low/high), number of spools (single/double/triple), number of nozzles (single/double), fan/turbine coupling (geared/ungeared), and finally afterburner (present/absent) is given. Analyses for some (not all) types of turbofan are presented. Finally, turboramjet is presented. It is found in two configurations; wraparound or above/under types. Analysis of its single mode or combined mode is precisely defined.
