本文提出了在多管火箭发射装置发射时期与燃气动力干扰(旁泄流、被引射流和反溅流等)有关的脉冲发射效应、起始扰动和二次扰动,论述了火箭燃气射流对多管发射装置的有粘与无粘激波干扰结构流场机理,得到了发射装置迎气型面的压力分布规律,给出了分别由火箭燃气射流动量均化特性模型和气动力模型所算得的发射装置承受燃气冲击力的可靠定量结果。
This paper presents the pulsed emission effect, initial perturbation and secondary perturbation related to gas dynamic disturbances (side discharge, induced jet and back splash flow, etc.) during the launching period of a multi-tube rocket launcher. The effects of rocket gas jet to multi The mechanism of the flow field of the viscous and non-viscous shock wave interfering structure of the tube launcher was obtained. The pressure distribution of the launcher was obtained. The equations of the gas jet momentum averaging model and the aerodynamic model were obtained respectively Launch device to withstand the impact of gas quantitative and reliable results.
