Abstract

The invention discloses a double-helix inflatable deployment type spinning-stability reduction aircraft. The spinning-stability reduction aircraft comprises a rigid spherical nose cone, an inflatable circular-ring resistance surface, a sectional type diaphragm, a high-pressure gas cylinder, a pressure decompression valve, a guide tube and a cylindrical load box. The double-helix inflatable deployment type spinning-stability reduction aircraft provided by the invention is initially in a collapsed state; and when the aircraft reaches a predetermined rail, the pressure decompression valve is started, the high-pressure gas cylinder in the rigid nose cone starts inflating gas, and two spiral gas-inflating rings sequentially pass through the inner diaphragm to spirally ascend, expand, stretch and form. By virtue of ring slots between adjacent two spiral circular rings which are symmetrical clockwise (or anticlockwise) with a difference of 180 degrees, the structure spins up by virtue of aerodynamic force generated by detour-flow gas, so that the stability problem in a process that an inflatable deployment type reduction aircraft structure flies to enter or re-enter is solved; meanwhile, the resistance area of the structure is greatly improved by virtue of an inflatable deployment part, so that the reduction of the aircraft structure is effectively realized, and recycling of the load box is completed.

Description

technical field [0001] The invention relates to a double-helix inflatable expansion type spin-stabilized deceleration aircraft, which belongs to the field of variable configuration structure design of aerospace vehicles. Background technique [0002] CN104290921A discloses an inflatable deployment aerodynamic damping reducer structure. The inflatable deployment type deceleration aircraft has the disadvantage that it cannot spin itself during flight, cannot achieve spin stability, and is prone to the problem of structural attitude rollover. Contents of the invention [0003] In order to solve the problems of inability to spin itself and unstable attitude during flight in the existing technology of the inflatable deployable deceleration aircraft, the present invention provides a double-helix inflatable deployable spin-stabilized deceleration aircraft. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A double-helix...
