Downwash measurements behind a 12-ft diameter helicopter rotor in the 24-ft wind tunnel

R. A. Fail; R. C. W. Eyre (1949)

Some measurements of downwash have been made in a plane behind a 12-ft diameter helicopter rotor over a range of shaft inclination and tip speed ratio. In the various operating conditions, the tunnel tests are in reasonable ...
Low-speed experiments on the wake characteristics of flat plates normal to an air stream

R. Fail; J. A. Lawford; R. C. W. Eyre (1957)

Experiments on isolated fiat plates perpendicular to the wind are described. It is shown that the effects of aspect ratio on drag, base pressure and flow pattern are small up to A = 10. All of these rectangular plates shed ...
Preliminary Low Speed Wind Tunnel Tests on Flat Plates and Air Brakes: Flow, Vibration and Balance Measurements

Wind tunnel tests on a 6 ft diameter helicopter rotor

T. B. Owen; R. Fail; R. C. W. Eyre (1955)
Wind-tunnel tests on a 12-ft diameter helicopter rotor

H. B. Squire; R. A. Fail; R. C. W. Eyre (1949)

Measurements of the thrust, torque and flapping angle for a 12-ft diameter rotor over a range of blade angle, shaft inclination and tip-speed ratio have been made to give information on the validity of the standard rotor ...
