Problems solved by technology

The flatness error and angle error of the bonding surface during the processing of the block throat liner will cause a large error accumulation during the throat liner assembly process, which directly affects the gap control of the block throat liner bonding surface, and has a great impact on the final overall assembly of the throat liner. It is very difficult, which brings many difficulties to the precision bonding assembly of large throat liners

Abstract

The invention discloses a special device for precise block bonding of a throat liner of a large solid rocket engine. The throat liner comprises M identical throat liner blocks, all the M throat liner blocks are grouped in a manner that X throat liner blocks form a group, F groups of grouped throat liner blocks are formed, and finally the remaining Y throat liner blocks are used as adjusting throat liner blocks; and the special device comprises a grouped throat liner bonding clamp and an integral throat liner bonding clamp. Large-scale manufacturing of the throat liner of a jet pipe of the solid rocket engine can be realized by utilizing the special device, consisting of the grouping throat liner bonding clamp and the integral throat liner bonding clamp, for precise block bonding of the throat liner, and the manufacturing problem about a large-scale solid rocket engine is solved; and in addition, the precision of the throat liner assembled by the special device is high, and the product design precision requirement is completely met.

Description

technical field [0001] The invention relates to the technical field of precision bonding equipment for throat linings of solid rocket motors, in particular to a special device for blockwise precision bonding of throat linings of large solid rocket motors. Background technique [0002] In aerospace production, it relates to a processing and manufacturing method for a throat liner of a large solid rocket motor. As a key component of a large solid rocket motor (SRM), the throat liner of a large solid rocket motor has the characteristics of large size, complex shape and structure, and ablation resistance. Restricted by the preformed design of throat liner of large solid rocket motor, densification process and large C / C throat liner hot isostatic pressing equipment, it is difficult for solid rocket motor throat liner to carry out overall design and The overall manufacturing shape. In order to meet the development needs of large-scale and super-large-scale solid rocket motors, i...
