T形尾翼非对称载荷设计分析

Unsymmetrical Loads Design Analysis of T Tail

由于T形尾翼特殊的结构和气动布局形式,其临界载荷的确定除了要考虑对称载荷外,非对称载荷也有可能构成尾翼及后机身结构的设计情况。本文以CCAR25部为设计准则,系统分析了T形尾翼非对称载荷受载的模式与特点,给出了非对称载荷的分析方法与流程,并比较了各设计情况的临界载荷,最终确定出T形尾翼的非对称载荷设计工况。

During the calculation process of the T tail＇ s critical loads, in addition to considering the symmetrical loads, the unsymmetrical loads should also be taken into consideration due to the unconventional aerodynamic configuration and structure of the T tail. The modes and characteristics of the T tail＇ s loads were analyzed systematically according to the related criteria in CCAR25. The analysis method and procedure were established for the unsymmetrical loads of T tail, and the critical loads of different design conditions were compared and discussed. Finally, the design cases of the T tail＇ s unsymmetrical loads were determined.
