Auxiliary Power Systems an overview ScienceDirect Topics
An MT is a mechanism that uses the flow of a gas to convert thermal energy into mechanical energy. The technology used in the MT is derived from diesel engine turbochargers, aircraft auxiliary power systems, and automotive designs. MTs consist of a compressor, combustor, turbine, and generator, as shown in Fig. 2.3 [6].
