First-child-stage parachuting-recovery carrier rocket

Abstract

The invention relates to a first-child-stage parachuting-recovery carrier rocket. The first-child-stage parachuting-recovery carrier rocket is combined by two stages of rockets and comprises a recovery system arranged in a shell of a first-child-stage rocket, wherein the recovery system comprises a speed reducing device and a buffering device; the speed reducing device is arranged at the position close to the interstage section of the shell and comprises a supporting frame connected with the inner wall of the shell; a parachuting device is arranged on the supporting frame and is used for reducing the speed of the separated first-child-stage rocket in the falling process; the buffering device comprises two buffering airbags, one buffering air bag is arranged at the position close to the interstage section, the other buffering airbag is arranged at the position close to the tail section, and the two buffering airbags are used for buffering the first-child-stage rocket in the landing process. The first-child-stage parachuting-recovery carrier rocket has the advantages that the first-child-stage rocket can land smoothly without damage under the common action of the buffering device and the speed reducing device, so that non-damage recovery of the first-child-stage rocket can be realized, and the first-child-stage rocket can be secondarily utilized, so that the launching cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of space transportation, in particular to a first-stage parachute recovery carrier rocket. Background technique [0002] In the initial stage of launch vehicle development, in order to achieve the goal of smooth launch, all aerospace countries do not consider the manufacturing and launch costs. However, with the development of aerospace technology, various aerospace countries gradually began to consider the issue of launch costs. Low-cost launch has become the key point of the space transportation system. development trend. As the new foreign launch vehicles represented by SpaceX (US Space Exploration Technology Corporation) Falcon series launch vehicles enter the international commercial launch market, the price advantage that my country's Long March series 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, ...

Problems solved by technology

[0003] Among them, during the launching process of a multi-stage rocket, most of the sub-stages are damaged after landing and cannot be reused. Most of them are disposable devices, which adds a great burden to the rocket launch cost. The basis for rocket reuse and cost reduction
