Separate assembly of a parachute, parachute system for aircraft recovery

Abstract

The invention discloses a separation component for a parachute. The separation component comprises a base, two separation turning plates, two rubber isolation pieces, a plurality of spring hinges anda plurality of partition plates, wherein the base is provided with an open cavity; the plurality of partition plates divide the open cavity of the base into a plurality of rope placement grooves usedfor accommodating an external sling or an external parachute cord; the two separation turning plates are connected to the two rubber isolation pieces to form two turning plate components, each turningplate component is connected to the base through the plurality of spring hinges, and the two turning plates integrally serve as a covering cap of the base jointly; and the spring hinges are used forproviding a pre-tightening force for closing of the turning plate components. According to the separation component, no excess material is thrown out in a separation process of the parachute cord or the sling, and the flight safety coefficient is improved. Through a parachute system using the separation component, the horizontal recovery of an aircraft can be realized, and the parachute system belongs to the technical field of rocket recovery.

Description

technical field [0001] The invention relates to a separation component of a parachute and a parachute system used for aircraft recovery, and belongs to the technical field of rocket recovery. Background technique [0002] The recovery of high-speed aircraft has always been a difficult point in engineering. At present, more mature solutions include the horizontal landing recovery of the US space shuttle and the parachute recovery of the X-38 verification aircraft. Especially for small-sized high-speed aircraft, the method of drogue parachute + main parachute is often used. Recycle. However, high-speed aircraft are faced with severe aerodynamic heating during flight, and sometimes the surface temperature is as high as hundreds of degrees Celsius. Ordinary aramid and brocade paracords cannot withstand such an environment. If you want to achieve parachute recovery, you can also meet the requirements of the flight profile , it is necessary to design the retractable separation me...

AI Technical Summary

Problems solved by technology

[0005] Due to the relatively new field, the retractable separation mechanism between the parachute recovery parachute and the cabin is still in its infancy in China, and there is no mature design of a type, and there is even a blank in the integration of the separation component's anti-heat insulation structure

[0006] In addition, rockets and other aerospace vehicles are mostly used for one-time use, the cost remains high, and the launch cycle is long. Realizing the recovery of aircraft is an inevitable way to solve the high cost and long cycle.

At present, there are mainly the following ways to realize the recovery of the aircraft: SpaceX’s Falcon 9 rocket reverses the thrust to slow down and deploys the landing legs to land smoothly. This recovery technology has high requirements for landing attitude control and greatly relies on the development of liquid engine technology. , the technology is very difficult and the cost is very high; the solid booster of the European Ariane-5 launch vehicle is recovered by parachuting, and its lifting point is located at the head of the booster, and it falls on the water in a vertical posture. The impact of landing is relatively large, which can easily cause damage to the structure of rockets and other aerospace vehicles
