A parachute system for aircraft recovery and landing recovery method

Abstract

The invention relates to a parachute system for aircraft recovery and a parachute recovery method, and belongs to the technical field of rocket recovery. When a drag parachute is opened, a hanging point is positioned behind the mass center of an aircraft, so that the stability of the attitude of the aircraft is favorably kept, and the drag parachute is in close contact with the wall surface of a main parachute bay due to the large size of the main parachute; if the exit angle of a main parachute bag is smaller, the main parachute bag is easily clamped in a main parachute cabin to cause failureof opening the main parachute, so that the hanging point of the drag parachute is instantly switched to the front of the aircraft before the main parachute bag exits the cabin, the aircraft is liftedup, a certain angle is created for the exit of the main parachute bag, and smooth exit of the main parachute bag is realized; when the main parachute is opened, the opening force is larger, and if the aircraft with a single hanging point structure is adopted, the aircraft is easy to roll and is wound with a hanging belt of the main parachute, the parachute opening failure is caused, and the horizontal recovery is difficult to realize; and a front hanging point support of the main parachute is fixed in front of the center of mass, and a two rear hanging point supports are fixed behind the center of mass, so that the aircraft can be prevented from being overturned and wound when the main parachute is opened, and the horizontal recovery of the aircraft can be realized.

Description

technical field

[0001] The invention relates to a parachute system for aircraft recovery and a landing recovery method, belonging to the technical field of aircraft recovery. Background technique

[0002] At present, 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...
