The Solid Rocket-Ramjet Engine Thrust Calculation And Experimental Research Of Connected-Pipe Testing

The research of the high-powered solid rocket-ramjet engine has been launched, which is one of the key technologies of the middle-long and supersonic missile project. The determination of solid rocket ramjet thrust and testing method are the important basis of the developing engine.An experimental program evaluating solid rocket-ramjet in NWPU connected-pipe facility is underway. According to the definition and expression of the thrust, as well as the condition derived from them, a method of solid rocket ramjet thrust determination and its program are provided on the basis of engine ground simulation test.In order to determination the thrust, the thrust definition and many control parameters are analyzed discussed, which mass flow rate and flight altitude are involved.It is difficult to measure the flight thrust of solid rocket ramjet directly. It is determined now by calculation with mathematical relationship of the flight thrust to the physical quantities which can be measured directly.The optimization of the software development platform is also analyzed inspect of the solid rocket-ramjet developmental program.The comparison of calculation results with experimental data confirms the reliable of the determination method of the flight thrust.
