Use of Jet Drives for Wind Tunnels of High Velocity (Uber die Verwendung des Strahlantriebes bei Windkanalen Hoher Geschwindigkeit).

摘要

Jet drives have been used successfully many times in foreign countries for small wind-tunnel installations of high velocity. The question is treated in the following report as to whether such a drive is essentially economical from the viewpoint of energy consumption, and further as to how the ratio of weight of driving material to weight of induced air changes with the pressure of the available driving material. These relations are calculated on the supposition that the speed of sound will be attained in the test section, and they are compared with experimental results.
