美国火箭公司设法进入商业卫星发射市场的努力,自1985年以来一直不成功的.但目前它能依靠改名叫天鹰座的新型助推器来实现了.该助推器由一个芯级、2个捆绑助推器及一个顶级组成.它能够把1133kg 送入160km 的极轨道,能把1542kg 送入160km、倾角28°的轨道,发射成本为每公斤1746美元(总计在2百万元以内).美国火箭公司的发射工具的关键是一种非爆炸的、高性能的固液发动机,它使用的是固体碳氢燃料和 Efforts by the U.S. rocket company to get into the commercial satellite launch market have been unsuccessful since 1985. But now it can be achieved with a new booster called Aquila, a core-level, 2 Bundled booster and a top-level unit that can send 1133kg into a 160km polar orbit, deliver 1542kg into a 160km, orbit at a 28 ° angle at a launch cost of $ 1,746 per kg (totaling under $ 2 million) The key to Launch ’s launch vehicle is a non - explosive, high - performance solid - liquid engine that uses solid hydrocarbon fuels and
