[0037] The stratosphere, which is about 20 kilometers above sea level, has great application prospects in the fields of earth observation and communication because its altitude is higher than the general aviation altitude and much lower than the satellite altitude. Therefore, it is very necessary for the floating flight system to achieve long-term flight or long-term residence in the stratosphere within a certain area.

[0038] At present, floating flight systems use aircraft such as stratospheric airships and stratospheric drones, but these aircraft do not have practical capabilities. Based on this, the floating flight system uses superpressure balloons, which can fly for a long time in the stratosphere for dozens to three hundred days. However, due to the characteristics of superpressure balloons that float freely with the wind, they cannot achieve regional residence; and they cannot fly in a specified direction. Even if the flight direction is controlled by propellers, due to the large volume of the superpressure balloon, the wind resistance is also large, and the flight altitude is too high and the atmospheric density is low, resulting in low propeller thrust and efficiency. Relying on propeller thrust to resist balloon wind resistance for a long time requires huge energy, and it is difficult to achieve long-term headwind flight.
