本研究介绍了用于战斧限制性点火试验的厚壁式同心筒发射装置的结构计算。发射装置各组件上的负载源于内部压力、温度和发动机推力。文章根据这些负载确定了各组件的大小并预测了其安全系数。试验用发射筒在推力和压力负载方面采用了安全设计方案。本研究的重点是结构上的热负载 ,因为高热应力可能使上气道下部产生局部弯曲变形。另外 ,在一维流体计算中未计及的局部“过热点”也有可能使结构出现腐蚀或熔化现象 This study describes the structural calculation of a thick-walled concentric cylinder launcher for the Tomahawk’s Axis Limits Ignition Test. The load on each component of the launcher originates from internal pressure, temperature and engine thrust. Based on these loads, the article determines the size of each component and predicts its safety factor. Test launch tube in the thrust and pressure load with a safety design. The focus of this study is structural thermal loading, as high thermal stress may cause local buckling of the upper airway. In addition, local “hot spots” not accounted for in one-dimensional fluid calculations may also cause the structure to corrode or melt
