Air floating aircraft with variable configuration

Abstract

The invention provides an air floating aircraft with a variable configuration, comprising an outer air bag and a configuration changing control device, wherein the outer air bag is filled with a buoyancy working medium; the configuration changing control device is located at the center part of the outer air bag; the configuration changing control device is composed of a coiling stretching arm and a coiling releasing mechanism; the coiling releasing mechanism is used for coiling or releasing the stretching arm to reduce or increase the height of the central part, so as to enlarge or reduce the volume of the outer air bag; when the air floating aircraft lifts off, the configuration changing control device stretches the outer air bag so that the buoyancy is increased to gradually lift the air floating aircraft; when the air floating aircraft descends, the configuration changing control device initiatively folds to reduce the capacity of the outer air bag, so that the buoyancy is reduced to gradually descend the air floating aircraft.

Description

technical field [0001] The invention relates to a variable-configuration floating vehicle, which is a comprehensive platform applicable to communication, investigation, earth observation, early warning, etc. in the adjacent space and stratosphere, and belongs to the technical field of floating vehicles. Background technique [0002] The airborne vehicle is an aircraft with power control and maneuverability based on the principle of Lighter-Than-Air (LTA). On November 21, 1783, the French first invented the hot air balloon, which is the earliest aerostat. In 1852, French engineer Giffard hoisted a 3-horsepower steam engine and propeller under an oval balloon to make the first blimp. In 1898, Earl Zeppelin of Germany designed and manufactured the rigid airship LZ-1 for the first time. This airship uses a skeleton to maintain the shape of the airbag, and uses a piston engine as power, so it has good flight performance and large loading capacity. In 1937, after the "Hindenburg...

AI Technical Summary

Problems solved by technology

Based on the special configuration of the blimp "High-altitude Sentinel", the principle of lift-off is the same as that of a balloon. The shape of the lift-off process is unstable, and the state transition is difficult to control after reaching the pressure altitude.

These aeroplanes all use propellers to generate thrust. At altitudes above 30km, the air is thin and the efficiency of the propellers is very low, and their efficiency matching points are not consistent with those at low altitudes.
