固体发动机喷管与壳体卡环连接结构初步研究

A Preliminary Study of Snap Ring Connecting Configuration Between Solid Motor Nozzle and Case

为探索大型固体火箭发动机喷管与壳体连接用的卡环结构,设计了一套试验研究装置。试验结果表明,该装置设计合理,所得试验结果与理论计算一致性较好,试验是成功的。由此使卡环结构应用于大型固体火箭发动机取得了突破性进展。

A set of testing devices is designed for the preliminary study of snap ring con- necting configuration between the solid motor nozzle and case.Good agreements are found between test results and theoretical calculation.The results have showe that the design is reasonable and this set of testing devices is favorable for the snap ring configuration to be used in large solid rocket motors.
