Parameter matching of hybrid coaxial rotors and multi-rotor UAV's power system

With the development of general aviation, UAVs are increasingly used in all areas of our life. However, electric multi-rotor UAV can't achieve long-endurance, large load transport due to battery energy density. And hybrid power system is a perfect solution to this problem. This paper raised a parameter matching method of the UAV's hybrid power system related to the pulling force, required power and flight performance. The UAV's power demand was taken as an entry point for parameter matching, and the match result was based to select power components. The test results of the components performance proved the matching methods' feasibility and accuracy. The structure of hybrid coaxial rotors and multi-rotor UAV is also tested to be achievable.
