Example Embodiment

[0025] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0026] Such as figure 1 As shown, the one-stage parachute recovery carrier rocket of the present invention is composed of two-stage rockets. One of the sub-stage rockets 100 includes a shell 1, and the inter-stage section 11 of the shell 1 is connected to the second-stage rocket. The tail section 12 of the shell 1 is provided with a power system 2, and a recovery system is provided in the shell 1 of a sub-stage rocket 100. The recovery system includes a deceleration device 4 and a buffer device; specifically, the rocket body structure in this embodiment It consists of fairing, payload bracket, secondary common bottom storage tank, primary and secondary interstage, primary liquid oxygen tank, primary inter-tank s...

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, ...
