takeoff thrust

The results showed that the horizontal takeoff vehicle with launch assist had some superiority on decreasing the ratio of thrust to initial weight, propellant and structure weight. Finally a group of optimal values of ground launch assist parameters were produced.

结果表明，助推发射水平起飞运载器在降低初始推重比、推进剂和结构质量等方面具有优势，最后得出地面发射参数的一组优化值。
