RBCC推进系统总体设计要求评估方法研究

An Analysis Model of System Design Requirements for RBCC Propulsion

为了适应以RBCC为动力的飞行器的总体发展需求,对RBCC推进系统总体设计要求评估方法进行了研究。分别提出了RBCC飞行器总体设计和推进系统总体设计结构矩阵,并分析了其应用范围以及对RBCC推进系统总体设计的指导作用。建立了发动机推力性能设计要求、推进剂质量需求和推进剂冷却性能需求的理论分析方法,实现了RBCC推进系统总体设计要求评估模型,并对空中载机发射的RBCC巡航飞行器进行了推进系统总体设计要求分析。

Under the demand of rapidly developed RBCC-powered vehicle, analysis model for RBCC propulsion system design requirements was investigated. Two Design Structure Matrix （DSM） were proposed separately for vehicle system design and propulsion system design. The applicability of both DSM was analyzed with its instruction for RBCC propulsion system design. Three requirements assessment models were established for engine thrust, propellant mass and coolant capacity, forming the analysis model of system design requirements for RBCC propulsion system, with its application on air-launched RBCC-powered cruise vehicle.
