| 摘 要： | 自由翼具有广泛的应用前景.本文研究了自由翼的翼型的几何特征,表明它们的中弧线都具有反折的特点;用数值计算方法对于同一种平面形状,翼型分别为G0741、MH45、MH49和MH78的四种不同的自由翼的气动特性进行了研究,明确了中弧线反折的程度对气动特性的影响.本文还对自由翼在非均匀气流环境中的气动特性进行了研究.

| Abstract: | The free-wing is a new concept and has promising applications for pilotless aircraft.The geometry of airfoils,which is proper for the free-wings,was numerically investigated and the results indicated that the airfoils must be featured by the S-shaped camber.The aerodynamic characteristics of free-wings with the same plane form but 4 different airfoils(GO741,MH45,MH49 and MH78 all have the S-shaped camber)were numerically simulated.The influence of the camber of the airfoils on aerodynamic characteristics has been presented.The influence of the non-uniform coming flow were also studied. |
