【摘要】 在西北工业大学NF-3低速风洞运用翼型气动力直接测量的方法对软质翼型进行风洞试验研究,对比了软、硬质翼型模型的试验结果。结果表明:软质翼型模型与硬质翼型模型在相同风速下具有不同的气动力特性。在一定风速下,软质翼型模型的表面会发生变化,从而影响了气动力。由于该影响非常复杂,因此在研究软质翼型模型的气动特性时进行风洞试验是必要的。更多还原

【Abstract】 An experiment investigation on aerodynamics of the model of soft airfoil is finished by the direct measuring of aerodynamic forces.The experimental results are compared with that of hard airfoil’s results.It’s shown that aerodynamic characteristics which the model of soft and hard airfoil are different at the same velocity.At the certain velocity,airfoil aerodynamic characteristics are influenced when the surface of soft airfoil is changed.Because the influence is very complicated,the wind tunnel test is need for researching aerodynamic characteristics of the soft airfoil.更多还原
