Abstract

The invention discloses a wind field self-adaptive adjustment device and method for near space aerostat. The device comprises a wind direction measuring module, a flight control computer and an actuating mechanism, wherein the wind direction measuring module is mounted on an aerostat body and is used for measuring the angle difference between the incoming flow direction and the direction of the aerostat body and outputting the angle difference; the flight control computer communicates with the wind direction measuring module, is used for receiving the angle difference, calculates actuation control data required by the aerostat to navigate towards wind according to the angle difference and outputs the actuation control data; the actuating mechanism is mounted on the aerostat body, communicates with the flight control computer, is used for receiving the actuation control data and controls itself according to the actuation control data to enable the course of the aerostat to deflect for a certain angle, so that self-adaptive adjustment of the aerostat navigating towards the wind. Area flight of the near space aerostat can be realized without accurate measurement of the real-time wind direction and wind speed of a wind field.

Description

technical field

[0001] The present invention relates to the field of wind field adaptive control, and more specifically, relates to an adaptive adjustment device and method suitable for heading control of an adjacent space aerostat in a resident mode. Background technique

[0002] The stable atmospheric layered structure in the adjacent space makes it basically free of convective movement in the vertical direction, and there is constant wind in the horizontal direction all year round. According to the above characteristics of near space, people have developed near space aerostats and applied them to mobile Internet communication, sensitive area monitoring, wireless network coverage, land and resource survey, emergency communication in disaster areas, etc. Adjacent space aerostats are different from fixed-wing aircraft. They need to stay in a certain area for a long time, and can rely on their own buoyancy to overcome the effect of gravity to achieve resident air. In additio...
