The overall design and technical characteristics of micro turbine engines(MTE) and auxiliary power unit(APU) were analyzed comparatively
and their similarities and differences were summarized.The results show that: the output powers of MTEand APUare equivalent.Moreover
the technologies of such two power systems are similar in terms of the designs or manufacturing of engines and their main components.MTEhas higher performance index
and APUpresents higher reliability
economic efficiency and longer service life through conservative design.So
a technical approach to develop Chinese APUbased on the technology of MTEhas been proposed.
