Correlation of model and full scale hinge moments. Part I: Frise ailerons on a Harvard II aircraft

Templin, R.J. (author), Etkin, B. (author)

An attempt has been made to correlate the lift and hinge moments measured in flight on a Harvard II aircraft with those obtained in wind tunnel tests of a 0.40 scale model of the outer wing panel. For the purpose of comparison, both model and full scale results were reduced to the common case of an aircraft with an infinitely rigid wing, no tail...

Canadian research in aerodynamic noise

Etkin, B. (author), Ribner, H.S. (author)

Canadian research on flow noise and some aspects of the aircraft noise problem is described . The work was done at the Defence Research Board, the University of Toronto Institute of Aerophysics and A. V. Roe (Canada) Ltd. Specific experimental and/ or theoretical investigations include: Aeolian Tones; Boundary Layer Noise (rigid wall and...

A simple method for the analogue computation of the mean-square response of airplanes to atmospheric turbulence

Etkin, B. (author)

The mean square response of an airplane to random atmospheric turbulence is, with certain restrictions. given approximately by the integral of the square of the response to the transient input function A.e--&,t. The values of A and √ are fixed by the intensity of the turbulence and the ratio of airplane size to turbulence scale. This result is...

Aerodynamic instability of non-lifting bodies towed beneath an aircraft

Etkin, B. (author), Mackworth, J.C. (author)

A theoretical and experimental (wind tunnel) investigation was made of the stability of a heavy body towed on a light cable beneath an aircraft. The theory showed the possible existence of a band of speeds within which the body is dynamically unstable, (swinging sideways). The experiments confirmed this prediction, and showed good agreement with...
