Ellipsoidal mixed umbrella

Abstract

The invention discloses an ellipsoidal mixed parachute which is composed of parafoil canopies, an ellipsoidal parachute canopy, wing ribs, winches, motors, parachute cords and control parachute cords, wherein the ellipsoidal parachute canopy is positioned in the middle of the mixed parachute structure, two sides of the ellipsoidal parachute canopy are respectively connected with the parafoil canopies, the parafoil canopies are in stitching connection with the wing ribs distributed along the span-wise directions of the parafoil canopies to form air chambers, and a plurality of round holes are formed in the wing ribs to enable air to flow so as to guarantee pressure equalization of each air chamber; the upper ends of the parachute cords of the ellipsoidal parachute canopy are connected with the bottom edges of parachute canopy panels, the wing ribs distributed along the span-wise directions in the parafoil canopies at two sides are stitched with upper and lower wing planes, parachute cords are fixed at the stitched parts of the lower wing planes and the wing ribs, and the lower ends of the parachute cords are connected on the winches through metal rings and control belts; and the control parachute cords are connected with the trailing edges of the lower wing planes of the parafoil, two sets of control parachute cords are respectively connected with the winches, and the motors drive the winches to rotate and drive the control parachute cords to pull down the trailing edges to deflect downwards, so as to realize control. The ellipsoidal mixed parachute has good gliding performance and controllability and also has an obvious decelerating effect.

Description

technical field [0001] The invention belongs to the technical field of paragliding, and in particular relates to an ellipsoidal hybrid umbrella. Background technique [0002] As a typical low-altitude gliding aircraft, the ram parafoil can not only be folded and packaged conveniently, is small in size, light in weight, easy to carry and carry, but also has excellent gliding performance, stability and maneuverability. It is currently used in the aerospace field widely. [0003] In the recovery process of the rocket booster, the crossing height is relatively large, the velocity variation range is wide, and the characteristics and motion laws of many atmospheric flows in the atmosphere and stratosphere are quite different. The recovery method usually adopts a multi-stage umbrella recovery system. . Use different umbrellas for different stages of recycling. For example, after entering the atmosphere, the circular parachute is first used to slow down. When the speed drops to t...

AI Technical Summary

Problems solved by technology

[0005] In order to avoid the deficiencies of the prior art, overcome the uncontrollability of a single circular parachute when it works, and the slow speed of parachute opening and deceleration when the parafoil works alone, the present invention proposes an ellipsoidal hybrid parachute
