Description
technical field [0001] The invention belongs to the field of test and research of thermal protection system of double-pulse engine, in particular, it relates to a connection and testing device for ablation test of double-pulse engine. 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 int...
