Engine Performance and Energy Management for engines with large power off-take EPEM

Important results from the project

Military aviation is undergoing a rapid technological shift where the need for electrical power is constantly increasing. The project has studied how increased power output in the form of electric power affects engine performance and how engine and aircraft systems can be designed to optimize the aircraft´s performance and energy efficiency. The project has provided information on how power output from the low and high pressure shaft affects the engine and its performance in different parts of the flight envelope and in different maneuvers in a typical fighter mission.

Expected long term effects

In a previous project, an engine model adapted for simulations with high power output integrated with a flight performance system has been developed. With this system, we have made studies of how large power outputs from the low and high pressure shaft affect e.g. aircraft performance and fuel consumption. A variable cycle engine variant has been studied in more detail and compared to a more conventional low bypass ratio turbofan engine with respect to engine and aircraft performance.
