Fixed-point recovery system and method for ballistic reentry satellite reentry capsule

Abstract

The invention relates to a fixed-point recovery system and method for a ballistic reentry satellite reentry capsule. The system comprises a controllable parafoil and a stable landing parachute. The controllable parafoil enables the horizontal movement direction of the reentry capsule to be controllable in the recovery process, so that the reentry capsule can fly towards a preset target landing point, the controllable parafoil can be separated from the reentry capsule, when the height of the reentry capsule is lower than a preset stable landing height, the controllable parafoil is separated from the reentry capsule, meanwhile, the stable landing parachute is pulled out, the stable landing parachute enables the horizontal speed of the reentry capsule to be braked, and the return capsule is driven to be converted into a vertical falling motion state and vertically falls to a preset area with the target falling point as the center. According to the method, the reentry capsule lands in a direction perpendicular to the ground, the reentry capsule can fall in the preset area, rapid searching and rapid loading and transportation can be achieved, and the problems that a reentry landing point is uncontrollable and the distribution area is large are solved.

Description

technical field [0001] The invention relates to a fixed-point recovery system and method for a ballistic reentry satellite return capsule, which can realize the landing point control and non-destructive recovery of a ballistic reentry satellite, and belongs to the field of aerospace aerodynamic deceleration. Background technique [0002] At present, returnable satellites are mainly used as carrying platforms for some scientific experiments such as microgravity and orbital environment. The return capsule of existing returnable satellites has a high landing speed and uncontrollable landing point, which is a one-time use, resulting in high costs for orbital tests. In addition However, due to the uncontrollable landing point, the search work after the satellite lands requires the mobilization of large-scale professional equipment such as helicopters, which also poses obstacles to the application of this type of test platform. [0003] Although the precise control of the landing ...

Problems solved by technology

[0004] The technical problem solved by the present invention is: to overcome the deficiencies in the prior art, to provide a fixed-point recovery system and method for a ballistic re-entry satellite return cabin, to solve the problem that although the return cabin of a traditional ballistic re-entry satellite can use a parafoil To achieve landing point control, there is a problem that the remaining horizontal speed is too high, which may easily cause deformation of the main structure of the return capsule, making it impossible to reuse
