摘要
随着美国"大力神4"首发全尺寸静态试验发动机PQM-1的失败,固体发动机点火瞬间的流固耦合现象逐渐得到了人们的重视。本文将流固耦合研究现状分为点火燃气流动、药柱变形和实验研究三个方面,综述了国内外的发展现状与趋势。结合我国发展的实际情况,初步探讨了研究固体发动机点火瞬间流固耦合的新方法。
The Fluid-Structure Interactions （FSI） phenomena in solid rocket motor ignition transient taken much more attention with the first prequalification motor （ PQM-1 ） in the Titan IV Solid Rocket Motor exploded during the first full - scale static test firing. In this paper, research actuality and development trend of FSI which are from three parts-ignition gas flow, grain deformation and experiment are summarized at home and abroad. Combined with our national development conditions,the new approach on studying coupled Fluid-Structure in SRM ignition transient are discussed preliminarily.
