摘要
将涡格法推广应用于计算外形复杂的蜂窝式栅格翼的气动特性．给出了亚、跨、超音速流中，栅格翼升力、力矩和阻力特性以及载荷分布，并分析了空气动力特点及几何参数的影响．计算结果表明，栅格翼作为一种新型的承力稳定面和控制面，在某些方面优于传统单翼．修正了БелочерквскотоСМ提出的空气动力等效条件。
The Vortex lattice method has been spread and utilized in calculating the aerodynamic characteristics for honeycomb grid fin with complex configurations.Calculation results of lift,pitching moment,drag coefficients and load distributions are presented in subsonic,transonic and supersonic flow,also its aerodynamic features and influence of geometric parameters are analyzed.Calculation results indicate that the grid fin using as an innovative aerodynamic stabilizers and/or control surfaces is much better than conventional planar fin in several aspects.Meanwhile,an equivalent condition of aerodynamics for various grid fin configurations, which is presented in reference,has been modified and validated by calculations.
