High-altitude balloon with controllable height and controllable track

Abstract

The invention mainly creatively provides a device for controlling a high-altitude balloon to ascend and descend and a method for controlling the track of the high-altitude balloon. A buoyancy unit (1) of the high-altitude balloon is composed of a skin, a force bearing band, a force bearing rope and the like. The size of the buoyancy unit can be changed through a buoyancy unit size adjusting device (2) arranged on the buoyancy unit (1), so that the buoyancy of the high-altitude balloon is changed, and control over ascending and descending of the high-altitude balloon is achieved. According to the differences of wind speeds and wind directions of the stratosphere at different heights, the track of the high-altitude balloon is controlled. A scheme that control over the height and the track of the high-altitude balloon can be achieved without releasing buoyancy lift gas in the high-altitude balloon is provided, and the high-altitude balloon has long-time region lingering capacity.

Description

technical field [0001] The invention relates to the field of general aviation, and can be applied to the lifting control and trajectory control of various high-altitude aerostats. Trajectory control, the whole process does not need to release the floating gas in the aerostat, the system has low power consumption, simple structure, light weight and low cost. Background technique [0002] High-altitude aerostats refer to aircraft that rely on buoyancy to lift into the air and work at altitudes of 18km and above. Due to the unique advantages of resources in the near space altitude of 20-100km from sea level, the development and utilization of near space resources is also the focus of scientists from various countries in recent years, and high-altitude aerostats are a core tool for developing near space resources . As an information platform near space, high-altitude aerostats can make up for the lack of communication means and improve the rapid response capability of space in...

AI Technical Summary

Problems solved by technology

Limited by the amount of buoyant gas and counterweight, the number of height adjustments is also limited, which is not suitable for the height control of long-duration flight of high-altitude balloons

[0004] The flight trajectory control of high-altitude balloons is affected by its large aerodynamic resistance, and it needs to be configured with a larger power plant, which consumes more energy. This is very complicated in engineering implementation, the cost is high, and it will consume more payload weight.
