Embodiment Construction

[0028] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown in the figure, the three-dimensional center of mass adjustment structure of the solid rocket motor provided by the present invention includes a support member 1, which is arranged at one end of the rocket motor casing 2; a limiting member 3 is arranged between the supporting member 1 and the rocket motor casing 2. A high and low step is formed between the support member 1 and the counterweight block 4, and the counterweight block 4 has an installation part 5 that cooperates with the support member and the limiting member; the counterweight block 4 is sleeved on the supporting member 1 and the limiting member 2 On the top, the counterweight 4 is connected with the limiter 3 .

[0030] like Figure 5 As shown in the figure, by forming a high and low step between the limiter 3 and the support 1, t...

Abstract

The invention provides a solid rocket engine three-dimensional mass center adjusting structure which comprises a supporting piece arranged at one end of a shell of a rocket engine. A limiting piece is arranged between the supporting piece and the shell of the rocket engine, high and low steps are formed between the limiting piece and the supporting piece, and the balancing weight is provided with a mounting part matched with the supporting piece and the limiting piece; the balancing weight is arranged on the supporting piece and the limiting piece in a sleeving mode, and the balancing weight and the limiting piece are connected together. The problems that in the prior art, the number of balancing weights is large, and each balancing weight needs to be provided with an installation position, so that design and machining are complex are solved. The structure is simple, the design is simple, the influence on the appearance of a product is small, and the requirement for excessive installation positions is omitted; less connection and high reliability are realized; the device is suitable for mass center and mass adjustment in a small range, can achieve small influence on space, and has the advantage of replacement.

Description

technical field [0001] The invention relates to the technical field of rockets, in particular to a three-dimensional center-of-mass adjustment structure of a solid rocket motor. Background technique [0002] When the product is in use, according to the characteristics of use, the requirements for the center of mass of the product structure are put forward. In order to meet the requirements, the structure needs to be adjusted and the center of mass adjustment measures are taken. The traditional method uses counterweights of specific shapes, such as hexahedrons, spheres, rings and other three-dimensional features with few adjustable features, and the installation position is fixed, which is difficult to change, such as figure 1 As shown in the figure, after a product is produced, it needs to be calculated adaptively, and the size and installation position of multiple counterweights need to be redistributed. Once determined, they can no longer be adjusted, and can only be adapt...
