Abstract

The end of the ROK-U.S. missile guidelines opened up the possibility of developing space launch vehicles for various platforms based on air and sea. In particular, the air-based space launch vehicle is an essential space power projection capability compared to the ground-based space launch vehicle in consideration of the geographical location of the Korean Peninsula, such as the deployment of various satellite orbits and the timely launch of satellite. In addition, compared to the ground-based launch vehicle, the cost reduction effect is large, and it has the merit of energy gain because it can be launched with the advantage of the aircraft's altitude and speed. Therefore, in this paper, the necessity of air-based space launch vehicle in the strategic environment of the Korean Peninsula is clearly presented, and through technology trend analysis of various air launch vehicle, the three methods are proposed to have the most efficient air-based space launch vehicle capability in the Korean situation.

한미 미사일 지침 종료를 계기로 공중, 해상기반의 다양한 플랫폼에 의한 우주발사체 개발 가능성이 열렸다. 특히, 공중기반 우주발사체는 지상기반 우주발사체 대비 다양한 궤도 운용, 적시적인 위성발사 등 한반도의 지리적 위치를 고려할 때 필수적인 우주전력투사 능력이다. 또한, 지상기반 발사체 대비 비용절감 효과가 크고, 항공기의 고도, 속도의 이점으로 발사할 수 있어 에너지 이득의 장점이 있다. 따라서 본 논문에서는 한반도의 전략적 환경하에서 공중기반 우주발사체의 필요성을 명확히 제시하고, 다양한 공중발사체에 대한 기술동향 분석을 통해서 현재의 우리나라 상황에서 가장 효율적으로 공중기반 우주발사체 능력을 확보할 수 있는 3가지 방안을 제시한다.
