Device for efficiently obtaining air lift through low-density gas

The invention discloses a device for efficiently obtaining air lift through low-density gas. The device can be used for upgrading lift systems of airships and fire balloons and promoting the large-lift and miniaturization development of the airships and the fire balloons. According to the device, the influence of density parameters on moving fluid pressure intensity changes is emphasized substantially, and the natural quality of the low-density gas is used for easily achieving the airflow density difference between the upper face and the lower face of a rotary part, so that excellent conditions are created for generating lift for the rotary part. When the rotary part rotates at a high speed, the lift is naturally formed. The effect is achieved through cooperative operation of the rotary part, a wind blocking part, an air pressure adjuster, an internal heater, an external heater and other parts. 一种利用低密度气体高效获取空气升力的装置。本发明可升级飞艇和热气球的升力系统，推动飞艇和热气球向大升力、小型化方向发展。本发明的实质是重视密度参数对运动流体压强变化的影响，并利用低密度气体的自然属性轻松实现旋转件上下面的气流密度差，
