초록

본 논문에서는 MATLAB/Simulink를 기반의 우주왕복선 주엔진(Space Shuttle Main Engine, SSME)의 툴박스 개발을 다루었다. 로켓엔진의 수학적 모델링에는 많은 시간과 신뢰성 확보가 필요하다. 로켓엔진 시뮬레이션 툴박스를 개발하면 이를 해결할 수 있으며 업그레이드와 새로운 엔진 개발의 용이성을 기대할 수 있다. SSME의 수학적 모델링은 7개의 지배방정식을 통해 유도한 32개의 미분방정식을 사용하여 구성하였으며 이를 구성요소 별로 모듈을 구별하여 SSME 시뮬레이션 툴박스를 개발하였다. 성능검증을 위하여 기존 시뮬레이션 결과와 비교하여 검증하였다.

This paper introduces the development of a toolbox for the Space Shuttle Main Engine(SSME) based on MATLAB/Simulink. A mathematical model of rocket engine creation and validation can be a complex process, the development of a rocket engine toolbox simplifies this process, thereby facilitating engine performance optimization as well as new design development. The mathematical modeling of the SSME dealt with in this paper is formed by 32 first-order differential equations derived from seven governing equations. We develop the toolbox for the SSME classifying each module according to the engine components. Further, we confirm the validity of the toolbox by comparing the results of the simulation obtained using the toolbox with those obtained using the original simulation of the engine.
