摘要
针对试飞过程中需在机头加装空速校准系统的要求,本文提出了一种前支杆结构的设计方法。通过数值计算分析了前置杆结构对原机气动特性的影响,同时应用PATRAN/NASTRAN对结构进行了强度分析,最后针对前支杆结构的受力特性对复合材料进行了优化设计。研究结果表明,该设计方法合理可行,设计结果满足设计要求,同时其优化方法可以为机头前支杆结构提供设计参考。
Based on the requirement of the airspeed calibration system, this paper describes a design method of composite front strut. The influence of the front strut on the aerodynamic characteristics of the original aircraft is analyzed by numerical analysis and the strength is analyzed by using software PATRAN/NASTRAN. Finally,according to the mechanical characteristics of the front strut, the composite layer is optimized. The results verify that the design method is reasonable and feasible. Meanwhile, the optimization can provide reference for the design of the front strut.
