摘要: 提出了一种根据气象条件、飞机特征、飞行条件预测积冰对飞机飞行动力学特性影响的估算方法.采用热力学平衡分析方法完成了积冰增长过程的数学描述,利用逐步线性回归方法建立了结冰飞机的气动模型,计算得到了结冰飞机的气动参数,计算结果与试验结果吻合较好,表明这种方法具有一定的工程实用性.并在此基础上研究了不同部位积冰对飞机纵向操稳特性的影响,通过数值仿真计算得出,结冰飞机气动特性的急剧恶化会导致其纵向操稳特性显著降低,严重时会危及其飞行安全.Abstract: A computational method was developed to predict the effects of airframe icing on aircraft flight dynamic characteristics according to atmospheric conditions, aircraft characteristics and flight conditions. Ice accretion scaling was performed by means of heat-transfer balance analysis, and aerodynamic model of iced aircraft was built by means of stepwise linear regression, the aerodynamic parameters due to ice accretion were computed by this model. The agreement of the computation results with the flight data indicates this method could be used to estimate the aerodynamic parameters at the analyses of longitudinal stability and handling quality. The penalties of aircraft longitudinal stability and control due to ice accretion on different region were investigated using this method. The results of computation demonstrate that the severe degradation of aircraft aerodynamic performance due to ice accretion may affect longitudinal stability and handling quality significantly, and endanger the flight safety.
