Bionic fish type suspended aerostat for near space

Abstract

The invention provides a bionic fish type suspended aerostat for a near space. The bionic fish type suspended aerostat comprises an outer skin, a tail fin, and one secondary airbag or more than one secondary airbags for inflating air, wherein the outer skin is formed by a plurality of alternatively-connected first rigid ribs and a first flexible rib; the tail fin is formed by a plurality of alternatively-connected second rigid ribs and a plurality of second flexible ribs; a buoyancy working medium is filled in the outer skin; the first rigid ribs and the second rigid ribs are manufactured by using a plurality of layers of Kapton thin films to laminate curing colloid; when the suspended aerostat blasts off until the air in the secondary airbags is discharged out and is in a stable form, the first rigid ribs and the second rigid ribs are cured in a rigid thin-wall shell structure in a space heat radiation condition; and the first flexible rib, the second flexible ribs, and the secondary airbags are made of a high polymer composite thin film material.

Description

technical field [0001] The invention relates to a bionic fish-type near-space aerostat, which is a comprehensive platform applicable to near-space and stratosphere communication, investigation, earth observation, early warning, etc., and belongs to the technical field of aerostats. 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" airship of the Germa...

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.
