Description

technical field [0001] The invention relates to the field of aircraft power systems, in particular to a power assembly suitable for solar-powered aircraft and an output control method thereof. Background technique [0002] Aircraft is an instrumental flying object that is manufactured by humans, can fly off the ground, fly in space and is controlled by humans in the atmosphere or in the space outside the atmosphere (space). Most of the existing aircraft use fossil fuels as energy sources. The use of fossil fuels as energy has the following disadvantages: first, fossil fuels are non-renewable energy; second, the burning of fossil fuels will cause environmental pollution; third, the overall weight of the aircraft will become lighter with the burning of fossil fuels, and the center of mass of the aircraft It will also change, which will affect the flight stability of the aircraft, bring difficulties to the design and control of the aircraft, and increase the corresponding rese...

Problems solved by technology

The use of fossil fuels as energy has the following disadvantages: first, fossil fuels are non-renewable energy; second, the burning of fossil fuels will cause environmental pollution; third, the overall weight of the aircraft will become lighter with the burning of fossil fuels, and the center of mass of the aircraft It will also change, which will affect the flight stability of the aircraft, bring difficulties to the design and control of the aircraft, and increase the corresponding research and development costs; fourth, the endurance of the aircraft will be limited by fossil fuels, and the fuel belt will be less. The capacity is shorter and the fuel belt is more, which will increase the overall weight of the aircraft

However, for aircraft that use solar energy as energy, the highest requirement is the efficiency of energy conversion, and the layout of the electric powertrain output used by existing aircraft is relatively single, which cannot meet the maximization of energy conversion efficiency in different flight states , not suitable for the energy conversion requirements of solar aircraft under limited power
