Abstract

A trajectory analysis program is developed using a 3DOF trajectory model for the performance analysis of geostationary launch vehicles by system options. Launch trajectory and the performance of injection at GTO was estimated using this program for several propellant options, engine types, number of engines and the location of launch site. Results of the analysis presents that the possibility of mission accomplishment by several design options using domestic launch sites and the development direction of GEO launch vehicles.

정지궤도 발사체의 시스템 옵션별 성능 해석을 위하여 3자유도 궤적모델을 이용한 궤도 해석 프로그램을 작성하였다. 이 프로그램을 이용하여 추진제의 종류와 엔진방식, 클러스터링 수, 그리고 발사장 위치 등을 옵션으로 두고 발사궤적과 정지천이궤도 투입성능을 추정하였다. 해석의 결과를 통하여 국내 발사장을 이용하여 임무 달성을 가능케 하는 다양한 설계 방안의 가능성과 함께 정지궤도 발사체의 설계 방향을 파악할 수 있었다.
