Aiming at the problem of insufficient data and multi-factor coupling in the control characteristics research of the integrated Vehicle, a build-up approach was proposed on the basis of the development experiences of X-51A and PRORA-USV1, to obtain sufficient aerodynamic data sets at a small cost and establish a control-oriented aerodynamic model. The result of static stability analysis for the model consistent with the result of X-51A in official report (that is, the vehicle is static instability), which proves that the aerodynamic model established has the aerodynamic characteristics of a class of vehicle such as X-51A. An improved pseudo-spectral method is proposed to calculate the optimal maximum range glide trajectory. The simulation results show that the aerodynamic build-up model is complete and the method of trajectory planning is effective.
