摘　　要：介绍了一种斜切喷管流场计算的新方法,即采用轴对称无粘流动模型,喷管喉部区域用Kliegel提出的小参数法求解,超音速段用MacCormack二步显格式空间步进求解。在流场计算的基础上,进行了斜切喷管的性能计算。A new methed that is applied to scarfed nozzle flowfield is presented.The flowfield model assumes that flow within the scarfed nozzle is axisymmetric and inviscid. The method of Kliegel's small perturbation is applied to transonic flow in the throat region of nozzle.A space-marching method of MacCormack finite-difference scheme is applied to supersonic flow.Based on flowfield computation,performace of the scarfed nozzle is calculated.
