Abstract
The rapid development of industry results in large energy consumption and a negative impact on the environment. Pollution of the environment caused by conventional energy sources such as petrol leads to increased demand for propulsion systems with higher efficiency and capable of energy-saving and emission reduction. The usage of hybrid technology is expected to improve energy conversion efficiency, reduce energy consumption and environmental pollution. In this paper, the simulation platform for the hybrid unmanned aerial vehicle (UAV) has been built by establishing the subsystem models of the UAV power system. Under the two chosen working conditions, the conventional cruise flight mission and the terrain tracking mission, the power tracking control and Q-Learning method have been used to design the energy management controller for the hybrid UAV. The fuel consumption and pollutant emissions under each working condition were calculated. The results show that the hybrid system can improve the efficiency of the UAV system, reduce the fuel consumption of the UAV, and so reduce the emissions of CO2, NOx, and other pollutants. This contributes to improving of environmental quality, energy-saving, and emission reduction, thereby contributing to the sustainable development of aviation.

Summary
The rapid development of the aviation industry brings great social progress and economic benefits, and brings increasing contentious environmental pollution problems. It has become a common goal for the development of the aviation industry to ensure the development and protection of the environment on which human beings depend [1,2]. The fuel used in conventional aircrafts is mostly the aviation kerosene, which mainly emits carbon dioxide (CO2 ), nitrogen oxides (NOx ), hydrocarbons (Cx Hy ), carbon monoxide (CO), and other pollutants [5,6]. The NOx emitted by aircraft can change the composition of chemical molecules in the atmosphere [10].
