Subsonic-speed airfoil with high lift-drag ratio

  title={Subsonic-speed airfoil with high lift-drag ratio},
  author={乔伟 and 王洪伟},
The invention belongs to the technical field of plane airfoil design and particularly relates to a subsonic-speed airfoil. On the premise of ensuring that the drag divergence mach number is not lower than 0.65 and the relative thickness and the trailing edge thickness are not obviously reduced, compared with the existing internationally disclosed moderate-speed high lift airfoil MS (1)-0317, in the design state of the project, the pneumatic properties of the airfoil which is invented by the… CONTINUE READING
