The UIUC Airfoil Coordinates Database includes the airfoils, and they cover a wide range of applications from low Reynolds number airfoils for UAVs and model aircraft to jet transports and wind turbines. Originally the site included mostly low Reynolds ...Mechanical Engineering questions and answers. Consider a 3-bladed propeller, D = 2.5 m with a Clark-Y airfoil whose characteristics are described in NACA TR-640 (see Propellers folder on Canvas). (Watch for number of blades! Use Figs. 9-11). The propeller is mounted on a single engine airplane cruising at 134 m/s (~300 mph) in air that has a ...Airfoils. Airfoils of U S and Canadian Aircraft. by David Lednicer.

Characteristics of Clark Y airfoils of small aspect ratios This report presents the results of a series of wind tunnel tests showing the force, moment, and autorotational characteristics of Clark Y airfoils having aspect ratios varying from 0.5 to 3. An airfoil of rectangular plan form was tested with rectangular tips, flared ...Federal Aviation Administration Oct 1, 2016 · An experimental wind tunnel investigation was undertaken to determine the effect of Gurney flap on the aerodynamic characteristics of Clark y-14 airfoil wing at a Reynolds number of 2.1x10 5. The ... Back to Results.
