Abstract

The invention discloses a series hybrid electric aircraft and a control method thereof. The Series hybrid electric aircraft includes a hybrid power system. The hybrid power system includes a power battery, an extended range system and an electrical driving system. The extended range system includes an electric generator and a rotary expansion engine connected with the electric generator and driving the electric generator to generate electricity. The electrical driving system includes a propeller and a driving motor providing driving force for the propeller. The power battery provides power forthe driving motor. The series hybrid electric aircraft of the series hybrid electric aircraft and the control method thereof adopts a series hybrid power system, achieves a design concept of energy saving and environmental protection being a control strategy and a control strategy of whole system power controlling parameters to real-time switch a whole machine, improves the energy demand allocation status of the hybrid power system under different working modes and working conditions, saves energy consumption, reduces environmental pollution and alleviates the energy crisis.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular, the invention relates to a serial hybrid aircraft and a control method thereof. Background technique [0002] With the rapid development of new energy electric vehicles, electric bicycles, electric aircraft and other electric products, the research on the control strategy of electric products has gradually matured, but limited by the development of power battery technology and fast charging technology of charging piles, electric products It is difficult to greatly improve the endurance of electric products, so the hybrid control mode has become the only way to improve the endurance of electric products. At the same time, considering the simplicity of the control strategy, the hybrid system adopts a series type. Combined with the rapid development of the current hybrid aircraft, under the concept of national energy conservation and environmental protection, the control strategy of ...
