Abstract: The method of load spectrum derivation for trainer engine design is presented. The main steps are: selecting reference aircraft engine, measuring active engine load spectrum, predicting new engine flight mission profiles and drawing up design duty cycles of the new engine’ As a general method, it can be used for other typical engines to certain extent.
