Furthermore the performances of heat transfers including corrugate plate, tube and fin-tube were compared under the same conditions. The results show that when the air frontal velocity is between 2.45 and 4.1m/s, the overall heat-transfer coefficient of plate heat exchanger ranges from 100 to 160 W/m^2/ equal to one sixth of that of fin- tube cooler based on tube outside area, which is about 70% higher than that of tube cooler. The volumetric heat transfer capacity of plate cooler is 1.5 times as that of fin-tube cooler and 15 times as that of tube cooler. The heat transfer capacity of per unit power of plate cooler is 5.5 times as that of tube cooler and similar results for fin-tube cooler.

在相同工况下，比较了波纹板式、光管式和翅片管式空冷器的性能指标，结果表明：迎面风速在2.45~4.1m/s之间，波纹板式空冷器传热系数达到100~160W/平方公尺/℃；约比光管式提高70%，但只有以管束外表面为基准的翅片管式传热系数的六分之一；板式空冷器单位体积换热量约是翅片管式空冷器的1.5倍，是光管式的15倍；板式空冷器单位功耗换热量约是光管式空冷器的5.5倍，而翅片管式空冷器与光管式空冷器则相差不大。

As a result, it shows thatthe static or dynamic subsystem optimum alone is not equal to the system optimum. Three initial value problems met in the optimal design of flying vehicle are studied andconclusions are derived that: orthogonal test method can be adopted to decide the initial valueof static optimization problem, some mathematical techniques can be used to deal with thecostate variables of Maximum Principle and decide the initial value of the costate variable,the indirect method can be used to get the analytical solution under ideal case to guide thechoice of the initial control curve in the direct method. With some numerical examples oftrajectory optimization, it shows that all these methods are useful not only in accelerating theconvergence but also in converging to the global optimum.

针对飞行器优化设计中的三种初始值问题进行了研究，以远程弹道导弹弹道的工程优化为例说明，对于静态优化问题，采用正交试验法选取初始值，不仅可以大大加快收敛的速度，而且更有可能收敛到全局最优解；以气动力辅助变轨问题为例说明，用共态变量的一阶泰勒级数展开可以解决极大值原理中共态变量初值难于确定的问题；以二级弹道导弹的主动段弹道优化为例说明，利用间接法在理想情况下得到的解析解来指导直接法初始控制曲线的选择，将大大有利于提高直接法的收敛速度。
