固定翼飞机水上迫降漂浮特性计算方法研究

摘要

Floating performance is an important part of ifxed wing alrcraft ditching performance, which is directly related to the success of the crew evacuation after the alrcraft ditching. For the better study on this problem, alming at improving the calculation and analysis efficiency and accuracy of fixed wing alrcraft ditching floating performance, introduced an calculation method on alrcraft ditching lfoating performance, which was based on Archimedes statics theory, and established by the secondary development of the optimization module in CATIA Software. Taking the Boeing737-700 as the prototype, analyzed the effect of the breakage area and load on the alrcraft lfoating performance after ditching.%漂浮特性是固定翼飞机水上迫降性能的重要组成部分，直接关系到飞机水上迫降后乘员能否成功撤离。为了更好地研究这一问题，提高固定翼飞机水上迫降漂浮特性计算和分析的效率及精度，在阿基米德静力学原理理论基础上，通过对CATIA软件中优化模块进行二次开发，建立了一种飞机水上迫降漂浮特性计算方法；并以波音737-700飞机为原型机，分析飞机水上迫降后破口面积及重心位置对飞机漂浮特性的影响。
