The trajectory design and analysis of the return flying vehicle

In this paper, the complicated motion equations are established based on the dynamic characteristics of the return flying vehicle. This model is incorporated into an optimal control formulation that includes constraints on both the vehicle and mission parameters, such as the height, velocity, range, heat rate, aerodynamic load and dynamic pressure capability. How these models are appropriately employed is key to gaining confidence in the results and conclusions of the research. The resulting analysis demonstrates that the design method has good engineering application value.
