Problems solved by technology

[0003] The flight speed of a stratospheric airship is generally about ten meters per second. In the thin stratosphere environment, it is almost impossible to control the yaw of the airship through the tail rudder surface at low speed, which also affects the yaw of the stratospheric airship. Control brings considerable difficulty

Abstract

The present invention relates to a system, method and airship for yaw control of a stratospheric airship, said system comprising: a power propulsion device installed on the airship for providing propulsion power for the airship and forming a propulsion tail during the propulsion process flow area; the rotating empennage device is installed on the airship and is located in the propulsion wake area, including a rotatable lower empennage, and adjusts the rotation direction and rotation of the lower empennage in real time according to the required yaw moment of the airship Angle, the yaw moment required by the airship is formed in the propulsion wake area, and the yaw control of the airship is performed. The invention improves the efficiency of the yaw control of the stratospheric airship.

Description

technical field [0001] The invention relates to the technical field of airship yaw control, in particular to a system, method and airship for yaw control of a stratospheric airship. Background technique [0002] In the middle latitudes, the stratosphere is located at an altitude of 10km to 50km above the surface, while at the poles, this layer begins at about 8km above the surface. The atmospheric composition of the stratosphere is stable, the airflow flows horizontally, and there are basically no meteorological phenomena such as rain, snow, thunder and electricity; its air density is only 1 / 14 of that near the ground. Due to the altitude range of the stratosphere and its unique climatic conditions, it is the calmest section of the atmosphere, almost unaffected by the weather, and almost never wet. At the same time, the stratosphere has stable meteorological conditions and good electromagnetic conditions. characteristic. The best altitude for stratospheric airships is 18-2...
