Rotating parachute

Abstract

The invention discloses a rotating parachute. The rotating parachute comprises a top panel, a plurality of canopy enclosing panels and a plurality of parachute ropes, wherein the canopy enclosing panels are of a non-isosceles trapezoid block structure; the canopy enclosing panels and trapezoid side edges are in butt joint and are sequentially spliced into an integral body of an annular parachute surface; the two ends of the trapezoid side edges of the canopy enclosing panels are in seam press connection; clearances are formed between the upper and lower canopy enclosing panels in the middle and are adopted as air inlets / exhaust holes; lengths of the upper and lower edges of the canopy enclosing panels are different, so that when the rotating parachute falls in the air, a canopy can be rotated under the action of restoring torque generated when an air current flowing into the canopy through the air inlets is discharged from the exhaust holes; one ends of the parachute ropes are connected with the bottom end of the parachute surface; the other ends of the parachute ropes are combined and are connected with an anti-twisting ring; and the top panel is arranged at the top end of the parachute surface and is arranged at the center of the top of the parachute surface. According to the rotating parachute, structure permeation volume of the rotating parachute can be effectively increased, parachute opening speed of the rotating parachute is increased, reliability of the rotating parachute is improved, the technology is simple, and cost is relatively low.

Description

technical field [0001] The invention belongs to the technical field of deceleration parachute, in particular to a rotating parachute, which is especially suitable for the deceleration attitude adjustment of bullets and high-altitude steady-state scanning. Background technique [0002] In the field of weapons or aviation, most smart weapons and ammunition need to achieve deceleration, attitude adjustment or drive rotation through parachutes. The rotating parachute is a typical device used to achieve deceleration, attitude adjustment or rotation of weapons and ammunition. [0003] Rotating umbrellas are usually composed of irregular canopy panels and umbrella ropes, and are stitched together by two ends of several canopy panels. Or the opening line of defense on it, the length difference of the umbrella rope and other asymmetric structures to realize the reaction torque generated by the exhaust gas in the exhaust port of the rotating umbrella when the rotating umbrella is work...

AI Technical Summary

Problems solved by technology

[0005] However, the rotating umbrella with the above-mentioned structure has a large air flow rate and a slow opening speed, so that the opening reliability of the rotating umbrella is low, and the usability is not high, so it cannot be applied to actual needs.
