Abstract

The invention provides a liquid bidirectional pump system and a stratospheric airship attitude adjusting device adopting the same. The liquid bidirectional pump system is provided with a first end anda second end and comprises a gear pump system, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve, wherein the first end of the liquid bidirectional pump system, the first end of the first electromagnetic valve and the first end of the fourth electromagnetic valve are in communication; the second end of the first electromagnetic valve, an inlet of the gear pump system and the first end of the third electromagnetic valve are in communication; the second end of the fourth electromagnetic valve, an outlet of the gear pump system and the first end of the second electromagnetic valve are in communication; and the second end of the third electromagnetic valve, the second end of the second electromagnetic valve and thesecond end of the liquid bidirectional pump system are in communication. The stratospheric airship attitude adjusting device adopting the liquid bidirectional pump system changes the center of mass and the pitching attitude of a stratospheric airship by changing the mass of liquid in an end liquid storage tank.

Description

technical field [0001] The invention relates to the technical field of airships, in particular to a liquid bidirectional pump system and a stratospheric airship attitude adjustment device using the same. Background technique [0002] For general airships, the pitch attitude angle of the airship can be adjusted by controlling the tail rudder surface; or by changing the windward angle of the tail rudder surface, the tail can generate power in the pitch direction to achieve the purpose of adjusting the pitch angle of the airship. [0003] However, due to the low air density in the stratosphere, when designing a stratospheric airship, the tail rudder surface has little rudder effect and increases useless weight when flying at an altitude of 20 kilometers above sea level with an airspeed of less than 20 meters per second. Therefore, the empennage rudder surface should not be used on the stratospheric airship. [0004] In addition, at low altitudes, due to the high air density, t...
