摘要

In order to comprehensively considering influence and coupling effect of multi-disciplines, i. e. mass, aerodynamics, kinetics, trajectory, a kind of multidisciplinary design optimization (MDO) method was introduced. Some problems, definition, general flowchart and overall scheme of the method were discussed in details, and difficult and critical problems were analyzed, then a kind of solving scheme was proposed. The scheme was verified to be feasible and effective by the example. Compared with prototype rocket, payload ratio of the rocket with single-stage thrust is larger, the maximum Mach number is smaller, and the working time is shorter; under the same range, the maximum Mach number of the rocket with double-stage thrust is smaller than that with single-stage thrust, the total flight time is shorter, and payload ratio greatly decreases. Finally further investigation on the scheme containing concentration problem was discussed.
