为满足电控旋翼的气弹分析需要,给出了带襟翼翼型的综合时域非定常气动力模型,该模型可以计及襟翼移轴补偿的影响。之后通过与静态、动态风洞吹风数据的比较,验证了该模型的准确性。相关分析表明该模型在翼型未发生失速前具有良好的静、动态气动力预测能力。
In order to meet the needs of aeroelastic analysis of electronically controlled rotor, a comprehensive time-domain unsteady aerodynamic model with flap airfoil is presented, which can account for the influence of flaps compensation. After comparing with the static and dynamic wind tunnel air blowing data, the accuracy of the model is verified. The correlation analysis shows that the model has good static and dynamic aerodynamic prediction ability before the airfoil stalls.
