| Abstract: | For gaining a project of air vehicle with the least weight,three projects of hypersonic vehicles powered by different engine combinations are compared with each other.Based on the work-energy theory,an optimization method of overall parameters of hypersonic vehicle is got by setting a uniform optimization restricting condition.Optimization calculation is carried out by using special software.Finally,the result of comparation between 3 hypersonic vehicle projects is shown by analyzing calculating data. |
