| 摘 要： | 从格林定理出发,在边界上布置Rankine源和偶极子,分别用定常和非定常方法对二维地效翼的性能进行计算,构建一种处理地效翼问题的计算模型.详细介绍这种方法的理论推导和计算过程,并经过试算确定了适当的模型参数.通过对多个参数的变化调整,讨论离地间隙、攻角对二维地效翼升力的影响.大量的数值计箅和与试验数据的比较,证实该法作为地效翼问题的一个支撑模型是可行、可靠的.

| Abstract: | A valuable computation model based on Green's theorem is constructed to tackle the wing-in-ground effect problem.In this model,Rankine Sources and dipoles are placed on boundary surfaces,the steady method is used to compute the performance of 2D wing-in-ground(WIG) effect.Theory development and computation process of this method are discussed in details,and proper parameters of the model are determined by many numerical tests.The influences on the lift of 2D WIG effect are discussed by means of the adjustme... |
