발사체 고체추진제의 저장 및 시험 시 안전거리 산정에 관한 연구
A Study on the Calculation of Minimum Safety Distance during Storage and Combustion Test of Solid Propellants for Launch Vehicles
한-미 미사일지침 개정으로 우주발사체에 대한 고체추진제 사용 제한이 완전히 해제 됐다. 고체추진제는 1단형 과학로켓 KSR-1과 같이 고체추진제 로켓으로 활용 가능하고, 액체연료 발사체의 추력증강 부스터로도 활용 가능하다. 고체추진제는 액체추진제에 비하여 폭발 위험성이 낮은 장점이 있지만 브라질 알칸타라 발사장 폭발사고와 같이 사고 가 일어나면 대형 인명사고로 이어질 수 있다. 이와 같은 대형 인명사고를 예방하기 위해서는 고체추진제의 저장 및 시험 시 최소한의 안전거리에 대한 검토가 사업의 기획단계 부터 검토되고 반영 되어야 한다. 본 논문에서는 발사체고체추진제를 안전하게 사용하기 위한 최소한의 안전거리를 저장시설과 시험 시로 구분하여 산정 기준 및 사례를 제시하였다.
In accordance with the revision of the US-Korea missile guidelines, restrictions on the use of solid propellants for space launch vehicles have been completely lifted. The solid propellant can be used as a solid propellant rocket like the KSR-1 (Korea Sounding Rocket-1), and can also be used as a thrust augmentation booster for liquid fuel launch vehicles. It is known that solid propellants have a lower risk of explosion than liquid propellants. but if an accident such as an explosion at the Alcantara Launch Center in Brazil occurs, it can lead to a large-scale personal accident. In order to prevent such large-scale accidents, it is necessary to review and reflect the minimum safety distance during use, storage and combustion test of solid propellants from the planning phase of the project. In this paper, the minimum safety distance for safe use of the solid propellant is presented by dividing it into storage facilities and combustion tests.
