Numerical model for a commercial aircraft water landing

  • 摘要: 近海/跨海使用的飞机必须考核水上迫降性能,而目前飞机抗坠毁标准、设计方法和分析方法通常只考虑硬着陆情况,很少考虑水面迫降情况,这是由于水上迫降涉及多场耦合,问题十分复杂.为了简化问题,采用了解耦的方法,将仿真与试验相结合,利用MSC.PATRAN/DYTRAN软件平台,建立全机有限元模型,包括全尺寸机身、机翼和尾翼结构,并导入具体参数,对13种工况条件进行了动力学数值仿真计算.预测了飞机撞击水面过程中结构的瞬态应力分布,对飞机机身下部蒙皮进行了强度分析,表明飞机在着水过程中蒙皮不会发生损坏.
