针对某超音速飞机的三角翼,设计了带平行翼梁的梁式三角翼结构和带内撑梁的梁式三角翼结构两种方案;分析了三角翼两种结构方案的受力特点,并采用有限元方法对比分析了两种结构方案的强度和刚度特点。通过分析和比较得出了带平行翼梁的梁式三角翼结构受力特性更好,更适合于能够布置中央翼的三角翼飞机。
Aiming at the delta wing of a supersonic aircraft, two schemes of the beam delta wing with parallel spar and the beam delta wing with inner spar are designed. The force characteristics of the two structures of the delta wing are analyzed. The finite element method is used to analyze the strength and stiffness characteristics of the two kinds of structures. Through the analysis and comparison, it is concluded that the beam delta wing structure with parallel spars has better mechanical characteristics and is more suitable for the delta wing aircraft capable of arranging the central wing.
