High-altitude balloon flight direction control system and method

Abstract

The invention relates to a high-altitude balloon flight direction control system and method. The system comprises a high-altitude balloon, a parachute and a nacelle which are connected in sequence, and further comprises a net light device, a net weight device and a control module, and the net light device is connected with the top of the high-altitude balloon, is always in a net light state, obtains position information and corresponding wind speed and direction in real time and sends the position information and wind direction to the control module; the net weight device is connected with thebottom of the nacelle, is always in a net weight state, obtains position information and corresponding wind speed and direction in real time and sends the position information and the wind speed anddirection to the control module; and the control module is used for controlling the flight direction of the high-altitude balloon based on the position information and the corresponding wind speed anddirection of the net weight device and the position information and the corresponding wind speed and direction of the net weight device. According to the invention, the high-altitude balloon can be controlled to select the optimal flight direction and speed in real time, so that the flight path can be optimized, and long-time air parking in a certain range or circuitous flight in a larger range can be realized.

Description

technical field [0001] The invention relates to the technical field of aerostats, in particular to a high-altitude balloon flight direction control system and method. Background technique [0002] High-altitude balloons are unpowered aerostats that fly in the stratosphere, and their lift-off and flight working principles are constructed according to Archimedes' buoyancy law and Newton's second law. After the high-altitude balloon reaches the flight height, it starts to fly with the wind. The direction of the flight depends on the wind direction at this height, and the speed of the flight is basically the same as the wind speed at the height of the balloon. However, for most areas on the earth, the wind speed and wind direction at different heights at the same location are very different, and this difference has certain latitude and seasonal rules. [0003] Taking most mid-latitude regions as an example, in summer and autumn, there is often a strong westerly wind at the low ...
