The New American Wind Tunnels

Published online by Cambridge University Press:  28 July 2016

Extract

Much has been learnt, in many branches of science and engineering, from the use of small scale models. The earliest successful experiments in humanly contrived flight with heavier-than-air craft, were made with small scale prototypes of the man-carrying machine of a later day : experiments with man-carrying craft, kite, glider and power-driven, followed.

Note on page 575 * The N.A.C.A. 20ft. Propeller Research Tunnel with a 2,000 h.p. motor gives a speed of 110 miles/hr. in an open section 20ft. diameter and 35ft. long, whereas for the same power Mr. Wood's design should give this speed in a section 24ft. diameter and 42ft. long.
