Preliminary Design Program for a High Thrust Liquid Rocket-Engine : Components Design for Static Performance Design

대추력 액체로켓엔진 예비설계 프로그램 : 정상성능 설계를 위한 구성품 모델링

In order to build a transient simulation program for a high thrust liquid rocket engine(LRE), a static performance simulation program for components were made. The components were the thrust chamber (combustion chamber and supersonic nozzle), centrifugal pump (impeller and volute casing), impulse turbine, and flow control devices (control valve and orifice). Simplified mathematical models based on classical thermodynamic and inviscid theories were used to remove complexity and enhance the utility of the program. We examined the results of each program qualitatively for validate each component modeling.
