Abstract:
Hybrid system is a new form of promotion between traditional aeroengine and full electric propulsion. Firstly, the architectural form, the structure features, the operating principle and development status of the hybrid system are sort out for unmanned aerial vehicle (UAV) requirements. Secondly, four key technologies of hybrid system are extracted and analyzed. Finally, some development trends and suggestions for the technology developments are proposed. The research shows that for the power demand of UAV, within actual technology condition, the hybrid system is an excellent solution given consideration to high efficiency and performance for aviation propulsion, which can truly realize the personalized design of UAV. At the same time, the key technology bottlenecks including overall system design, high efficiency and high work weight ratio electric machinery, integrated energy management and high energy density charge-storage, do exist within the hybrid system yet to be researched and resolved.
