固体发动机Φ200mm带喷管整体缠绕壳体的研制

Development of Φ200mm Integral Wound Chamber-Nozzle for Solid Rocket Motor

研制了3台Φ200mm带喷管不等开口整体经统壳体，并成功校验了带喷管壳体整体结构强度，所测壳体的实际爆破压强为11．6～13．0MPa，是设计爆破压强（8．2MP）的1．6～1．6倍。

Three integral wound chamber-nozzle 200mm in diameter with unequal polar openings were developed, and the integral structure strength of chamber-nozzle were successfully tested. The practical burst pressure of chamber case are 11. 6~13. 0MPa, 1. 4~ 1. 6 times the design pressure (8. 2MPa).
