According to the deformable multi-rotor airship, an air bag filled with light gas is mounted in a rack, and the air bag can be inflated and deflated with the light gas from a gas tank at any time through an airborne gas pump. The multi-rotor aircraft is high in maneuverability and stable in attitude control, and the air bag can provide extra buoyancy, so that loads of the rotors are reduced, the overall flight efficiency is improved, and the endurance time is prolonged. Air in the air bag can be compressed into the air tank through the air pump, and the size of the air bag is reduced to reduce wind resistance and enhance control capacity. Firstly, additional lift force is provided by adding the air bag, the power consumption of the aircraft is greatly reduced, and the aircraft is suitable for long-time hovering and low-speed cruising. And secondly, the design reserves the flexibility and controllability of the multi-rotor unmanned aerial vehicle, more complex and efficient control can be carried out, and the dynamic response speed of the aircraft is effectively improved. And finally, the air bag capable of inflating and deflating air in real time greatly enhances the environmental adaptability of the aircraft, and can effectively cope with various complex environments in low-altitude scenes.
本发明公开了一种可变形多旋翼飞艇,机架内挂载一个充满轻质气体的气囊,气囊可通过机载的气泵随时从气罐中充放轻质气体。多旋翼飞行器的机动性强,姿态控制稳定,而气囊能够提供额外的浮力,从而减轻旋翼的负载,提高整体飞行效率和续航时间。气囊内气体可以通过气泵压缩至气罐内,气囊体积缩小以减小风阻并增强控制能力。首先,气囊的加入提供了额外的升力,大幅减少飞行器功耗,适用于长时间悬停和低速巡航。其次,该设计保留了多旋翼无人机的灵活性和操控性,能够进行更加复杂且高效的控制,有效提升飞行器动态响应速度。最后,可实时充放气体的气囊大幅增强了飞行器的环境适应能力,能够有效应对低空场景下各种复杂环境。
