Study of Integrated Optimization Method of Trajectory/Vehicle Overall Parameter

Based on the theories of flight dynamics, modern control theory and optimization method, using two integrated optimization methods of trajectory/vehicle overall parameter-static state+dynamic state integrated optimization method and parameter optimization method, optimization of reentrying trajectory/overall parameter of manned spacecraft is studied. And also the characteristics of the two integrated optimization methods are compared. Using numerical calculation, optimal roll program, the ratio of lift and drag, reentry angle and reentry time of spacecraft are gotten. From the analyses of the results, it states that the two integrated optimization method can get good calculating accuracy.
