摘要
为研究格栅尾翼/舵主要几何参数——格数、格壁厚度、格壁前缘倒角对其气动特性的影响,在翼高、翼宽、弦长一定的条件下,设计了一组具有不同格数、格壁厚度和格壁前缘倒角的格栅尾翼模型,进行了风洞测力实验,得到了格数、格壁厚度、格壁前缘倒角对气动特性影响的基本规律.基于对实验结果的分析,提出了适于滑翔增程制导武器采用的格栅尾翼气动外形参数的选择方法及对结构设计和材料的要求.
Wind tunnel experiments were conducted to study the aerodynamic characteristics of the grid fins. A series of wind tunnel experiment models with various grid fins having the same chord, same frame, different grid number, different thickness of grid wall and different angle of grid wall leading edge were designed and used in studying the influence of the grid number, the thickness of grid wall and the angle of grid wall leading edge to its aerodynamic characteristics. Based on the test data, the method of how to select the grid fin' s geometric parameters, and the requirement of material and construction design that suitable for the gliding extend range guided weapon, are put forward.
