The ratio of aircraft length to maximum cross sectional area also influences the intensity of the sonic boom.
飞机的长度和最大横截面面积之比也会影响音爆的强度。

Considering the boomcross section as a whole, a parametric finite element model and a parametric optimization model for local stability calculation of a boom structure were established.
将吊臂截面作为整体考虑，建立了吊臂结构局部稳定性计算的参数化有限元模型和参数优化模型。

When the box section design boom and a reasonable cross-section are put in danger of partial reinforcement, the arm can have good stiffness, strength, vibration stability.
