뭔가했더니 마침 옛날에 미국서 Electromagnetic launcher 생각나서 납득이 갔다

국내선 이걸로 소형위성 쏘려고 생각한다더구만


그리고 공중레일건 보쉴?


The Universities of Texas, Minnesota, and New Orleans and Texas Tech University are undertaking research supported by the Air Force Office of Scientific Research on critical issues for launch to space from a railgun carried on an airborne platform. The University of Texas at Austin is studying techniques to achieve hypervelocity with a goal of 7 km/s: so far, 5.2 km/s has been achieved in a 7 m augmented railgun using a pre-injected plasma armature. Texas Tech University is studying distributed power feed concepts that will improve the efficiency of launch for a long railgun: so far, 11 km/s has been achieved with a plasma arc in a five-stage system. The Universities of Minnesota and New Orleans are investigating the aerothermal behavior of a 10 kg projectile for flight from high-altitude launch into orbit: so far, the results show that an acceptable amount (~15 mm) of nosetip ablation will occur. This paper provides an overview of progress in these areas; more details on specific topics are provided in companion papers.
