Embodiment Construction

[0023] A method for recovering a carrier rocket sub-stage of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. The present invention adopts a land landing recovery method of a parachute+airbag, which does not require re-ignition of the engine after the sub-stage is separated. Specific steps are as follows:

[0024] (1) On the premise of simplifying the interface with the overall structure of the first sub-level as much as possible, an installation platform is designed, and the platform is installed between the upper and lower half of the first sub-level inter-level section. Two stabilizer parachutes and their connection and separation mechanisms, two deceleration parachutes and three main parachutes are mainly installed on the platform;

[0025] A buffer airbag is respectively installed in the lower part of the cabin body of the first sub-stage of the launch vehicle and the lower part of the lower part of the...

Abstract

The invention provides a launcher sublevel recovery method. The launcher sublevel recovery method comprises the steps that 1, an installation platform is designed and installed between an upper half section and a lower half section of an inter-level section of a sublevel, two stabilizing parachutes, two deceleration parachutes and three main parachutes are installed on the installation platform, and the lower portion of an inter-level section cabin of a launcher and the lower portion of a rear transition section cabin of the sublevel of the launcher are each provided with a buffering air bag; 2, when the sub-level falls to the parachute-opening height, the two stabilization parachutes are horizontally popped, the sublevel is vertically stabilized under the action of the stabilization parachutes, the stabilization parachutes are separated from the sublevel, the two deceleration parachutes are pulled out by the stabilization parachutes, the deceleration parachutes are inflated to decelerate the sublevel, the upper half section and the lower half section of the inter-level section of the sublevel are separated, the three main parachutes are pulled out during separation, after the main parachutes are pulled straight, the deceleration parachutes carry the upper half section of the inter-level section to enable the upper half section of the inter-level section to be separated from the main parachutes, the sublevel is decelerated steadily under the action of the main parachutes, a hung sling is pulled out from one side wall of the sublevel after the sublevel is decelerated steadily, and vertical hanging of the sublevel is converted into horizontal hanging of the sublevel; 3, the buffering air bags are opened before the sublevel lands, and then recovering is completed.

Description

technical field [0001] The invention relates to a recovery method of a carrier rocket sub-stage. Background technique [0002] In the early stage of launch vehicle development, in order to achieve the goal of smooth launch, all aerospace countries do not care about the cost. With the development of aerospace technology, various aerospace countries have gradually begun to consider the issue of launch costs, and low-cost launches have become the development trend of space transportation systems. [0003] As the new foreign launch vehicles represented by the SpaceX Falcon series of launch vehicles enter the international commercial launch market, the price advantage that my country's Long March series of rockets had in the past no longer exists. In addition, the U.S. United Launch Alliance plans to significantly reduce the current launch price by 2020, and Europe and Japan are also embarking on a new round of work to reduce rocket manufacturing and launch costs. Therefore, my...
