Abstract

In present study, design and hot fire tests of the pryostarter are conducted. To prevent the turbopump RPM overshoot, regressive mass flow rate profile is applied. Sudden decrease of the mass flow rate at the end of the propellant burning is realized as well. Firing test results show good agreements with the design requirements. Through the study with ignition substance variations, combustion products and ignition performances are improved.

본 연구에서는 액체로켓엔진의 시동을 위한 파이로시동기의 설계 및 연소시험 연구를 수행하였다. 엔진의 시동 시에 터보펌프 RPM의 급격한 상승을 막기 위해 퇴행형 질량유량 선도를 적용하였으며, 연소 종단 시점에서 급격한 유량 감소 또한 구현하였다. 연소시험결과 파이로시동기 압력선도 및 연소 온도가 설계요구조건에 부합하는 것으로 확인되었으며, 점화제 변화연구를 통해 연소생성물 개선 및 안정적 점화를 구현하였다.
