Problems solved by technology

[0003] Usually, the flexible pipeline in the rocket engine adopts the metal bellows structure as the pipeline compensator. In order to prevent instability, the two ends of the metal bellows are provided with stabilizing rods. This structural design not only makes the structure not compact, but also the rigidity of the rods is low Affects the radial bending, which affects the compensation performance of the pipeline compensator

Abstract

The invention discloses a pipeline compensator with an inner support. The pipeline compensator with the inner support comprises a corrugated pipe body, wherein connecting flanges are fixedly arrangedat two ends of the corrugated pipe body, a bracket is fixedly connected to the inner surface of each connecting flange, connecting rings are fixedly connected to one sides, close to each other, of thetwo brackets, and one ends, close to each other, of the two connecting rings are hooked together. The pipeline compensator with the inner support is compact in structure, good in compensation performance and free of instability.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a pipeline compensator with inner support. Background technique [0002] The pitch, yaw, and roll attitudes of the launch vehicle during flight are achieved by changing the direction of thrust brought about by the liquid rocket engine swinging at a certain angle, which requires the relevant pipelines of the engine to be flexible pipelines to compensate for the The radial bending and axial stretching deformation of the road. [0003] Usually, the flexible pipeline in the rocket engine adopts the metal bellows structure as the pipeline compensator. In order to prevent instability, the two ends of the metal bellows are provided with stabilizing rods. This structural design not only makes the structure not compact, but also the rigidity of the rods is low. It affects the radial bending, thus affecting the compensation performance of the pipeline compensator. Contents of the inv...
