Double-pulse solid rocket motor soft compartment ablation test device

Abstract

The invention discloses a double-pulse solid rocket motor soft partition ablation test device, comprising an end-burning charge cavity, a test-piece ablation cavity, a nozzle cavity and a central cubic connecting body (5); The charge cavity and the specimen ablation cavity are symmetrically installed at both ends of the through hole of the central cubic connecting body (5), and the nozzle cavity is connected to the third hole of the central cubic connecting body (5); the test device The end-burning charge cavity blocking cover (1), the end-burning charge cavity shell (2), the central cubic connecting body (5), the nozzle cavity shell (6), the rear section of the nozzle cavity ( 9) The test piece ablation cavity shell (11) and the test piece ablation cavity cover (14) are made of high-strength 45 steel; The inner lining (7), the inner lining of the rear section of the nozzle cavity (10), and the inner lining of the specimen ablation cavity (12) are all made of EPDM rubber; the throat lining of the nozzle cavity (8) is made of graphite . The invention solves the problem that it is difficult to simulate and observe the working process of the double-pulse engine II pulse soft spacer.

Description

technical field [0001] The invention belongs to the field of experimental research on thermal protection systems of double-pulse motors, in particular to a soft interlayer ablation test device for double-pulse solid rocket motors. Background technique [0002] Solid rocket motors are widely used in various weapon systems because of their simple structure, convenient use, and reliable operation. However, with the gradual development of the aerospace field, the inherent defects of the uninterruptible and adjustable thrust of traditional solid rocket motors have become more and more prominent, especially when compared with the superior controllability of liquid rocket motors. Therefore, the research on the controllability technology of solid rocket motor is particularly important. [0003] After the two-way promotion between modern warfare and missile weapon systems, the latest research achievement of solid rocket motor technology - double pulse solid rocket motor came into be...
