Abstract:

The principles and performance feature of series and parallel turbo-electric hybrid engines are introduced in this paper. The sources of turbo-electric performance advantage are demonstrated. The key technologies of performance design， control system， electric motor design and heat management are analyzed based on the turbo-electric hybrid system architecture. The development of turbo-electric hybrid propulsion technology will bring disruptive impact on traditional aircraft engine. The original design philosophy of aircraft engine need to be broken through. The propulsion， electric and heat management are integratedly designed and the efficiency of aircraft engine system is further improved.
