基于CFD仿真的外翼断裂飞机安全飞行研究

摘要

The flight of the aircraft with outboard wing rupturing is a special problem about pneumatics and flight con-trol.The analysis model about the special pneumatics problem is set up by the CFD emulation method,and the control method about outboard wing rupturing aircraft aviating safely is brought forward.By the simulation computing,the conclu-sion is gained that the opposite damage most limit of the outboard wing based on the aileron balance method is 14.2%,and the opposite damage most limit of the outboard wing based on the side flight balance method is 24.5%.It provides the refer-ence and evaluation method for the aircraft with outboard wing rupturing flying.%针对外翼断裂飞机安全飞行问题，采用CFD 仿真方法，建立了针对该特殊气动问题的分析模型，提出了外翼断裂飞机安全飞行控制方法，并通过仿真计算得到，基于副翼平衡法的外翼相对损伤极限为14．2％，基于侧飞平衡法的外翼相对损伤极限为24．5％，为战时外翼断裂飞机带伤飞行提供了参考和评估方法。
