Model-Based Dynamic Performance Simulation of a Microturbine Using Flight Test Data
Microturbines can be used not only in models and education but also to propel UAVs. However, their wider adoption is limited by their relatively low efficiency and durability. Validated simulation models are required to monitor their performance, improve

Optimization of energy and exergy parameters for a conceptual afterburning turbojet engine
In this study, parametric cycle analysis of a conceptual turbojet engine with an afterburner (TJEAB) was conducted at sea level conditions-zero Mach. Based on this analysis, exergetic sustainability parameters of TJEAB were scrutinized for military mode (

Advanced Control of an Electric Fuel-Oil Pump for Small Turbojet Engines
One way to efficiently control the fuel flow of small turbojet engines is to use direct control of the speed of a suitable electric fuel pump, as opposed to using relief valves.

A review of studies on air-breathing turbine engines from an energy–exergy viewpoint [PDF]
Studies show that the analysis of the first law in air propulsion systems alone is not sufficient, and for a complete study of a system, the second law and exergy analysis should also be considered.
