추진시험설비의 사고피해영향분석 및 리스크 감소방안
Consequence Analysis and Risk Reduction Methods for Propulsion Test Facility
한국형발사체 개발을 위한 추진시험설비가 구축되고 있으며, 일부 시험설비는 구축이 완료되어 추진기관시험을 실시하고 있다. 추진시험설비의 구성은 엔진 시험체 등의 시험을 실시하는 테스트 스탠드와 추진제로 사용되는 케로신(Jet A-1) 및 액체산소(LOX) 등을 저장하는 설비 등 다양한 서브시스템과 부품들이 연결되어 있다. 테스트 스탠드는 엔진개발모델이 장착되고 추진제가 혼합되어 실제 연소가 이루어지는 곳으로서 큰 에너지긴장도 상태에서 고압으로 작동되는 추진시험설비의 특성상 화재·폭발의 위험성이 존재한다. 본 논문에서는 추진시험설비의 사고피해영향분석 및 리스크 감소방안을 수립하기 위하여, 테스트 스텐드에서의 추진제 누설사고 시나리오를 가정하고, TNT당량모델 실험식을 적용하여 폭발과압에 대한 사고피해영향을 분석하였고, 추진시험설비의 안전성 확보를 위한 리스크 감소방안에 대하여 기술적, 제도적, 관리적 안전대책에 대하여 제시하였다.
The Propulsion Test Facilities for the development of Korea Space Launch Vehicle-II are being built, some test facilities are completed and various combustion tests are running. The Propulsion Test Facilities consists test-stand, which carries out tests for engine development model, and various sub-systems and vessels containing LOX and Jet A-1 as propellant. There are always risks of fire and explosion at the test-stand since engine development model is conducted at test-stand with real combustion test with very high pressure, mixed propellant and high energy. In this paper, in order to establish the consequence analysis and risk reduction measures in the Propulsion Test Facilities, followings are considered. 1) a propellant leak accident scenario is assumed in test-stand. 2) TNT equivalent model equation based on blast wave of the explosion was used to analyze blast overpressure and impacts. Also, technical, systematic and managemental measure is described to ensure risk reduction for propulsion test facility.
