摘要
A nonlinear wind-tunnel and computational-fluid-dynamics-based model of the longitudinal and lateral-directional dynamics for an airbreathing generic hypersonic vehicle is developed. The equations of motion for the generic hypersonic vehicle are derived using Newton's and Euler's equations. Results from wind-tunnel investigations, computational fluid dynamics code simulations, and analytical techniques are used to develop a merged aerodynamic database. Nonlinear analytical optimization techniques are employed to generate analytical expressions for the aerodynamic coefficients. The coupling between the aerodynamics and the propulsion systems is included. As an example, the generic hypersonic vehicle dynamic model is linearized and its behavior is studied at 5 times the speed of sound.
