| 摘 要： | 针对不同已知条件，分别用Newton-Raphson迭代法和遗传算法确定了高超声速飞行器周期巡航的条件. 并且用胞映射法计算得到周期巡航不动点的吸引域. 结果表明，只要满足特定条件，高超声速飞行器就可实现周期巡航，且巡航初始值可在较大的范围内进行选择.

| Abstract: | According to different available conditions, periodiccruise conditions of a hypersonic vehicle are determined by Newton-Raphson'siteration and Genetic Algorithm. The attraction region of fixed pointsof the periodic cruise is obtained by a cell-to-cell mapping method. The resultsindicate that the hypersonic vehicle can cruise periodically under certainconditions and initial values of the periodic cruise can be selected in a widerange. |
