Gust response analysis of flexible aircraft with aerodynamic nonlinearity

  • 摘要: 针对大展弦比柔性飞机阵风响应问题,考虑在大攻角(AOA)情况下气动力非线性的影响,通过将修正的Theodorsen方法与片条理论相结合,得到非线性的时域非定常气动力;在此基础上,建立阵风干扰下的大展弦比柔性飞机非线性气动弹性模型,完整地发展了一种新颖的可考虑气动力非线性的大展弦比柔性飞机阵风响应分析方法.结合算例模型开展方法验证和数值仿真,对比翼尖和质心(CG)处阵风附加过载在线性和非线性情况下的变化.算例结果表明,考虑大攻角情况下的气动力非线性后,大展弦比飞机的阵风响应较线性情况有明显变化,翼尖处的阵风附加过载最多可减少41.7%,气动力非线性的影响不可忽视.
