The NAVAIRDEVCEN has developed an analytical model of an aircraft internal combustion engine for performance estimation of an integrated propulsion system. The engine model is designed to be integrated to a turbocharger and heat rejection system for performance design studies. The model accepts manifold air conditions, fuel/air ratio, engine delta pressure, crankshaft speed and coolant temperature as inputs to provide output in the form of brake horsepower, fuel flow, exhaust gas temperature and thermal flow rate. The analytical model has demonstrated good correlation with test data throughout a range of engine performance.
