Test of Two Custer Channel Wings Having a Diameter of 37.2 Inches and Lengths of 43 and 17.5 Inches (Five-Foot Wind Tunnel Test Number 545)
Abstract
The Custer Channel Wing is a wing-propeller arrangement designed to produce lift statically or to augment the normal lift when the vehicle has some forward velocity. Flight tests of an airplane incorporating two of these channel wings were conducted first by the inventor. The next test was conducted by the Air Materiel Command in the Five-Foot Wind Tunnel on a 1/3-scale powered model of one channel. Additional static lift tests of this same model but with additional improvements were made by the inventor and witnessed by an Air Materiel Command representative. These results are reported in reference 2. The last series of tests are those described in this report. Up to the time of this present series of tests both model and full scale tests of this arrangement were made under conditions which did not give accurate power input and thrust data. In this series of tests made on a 1/2-scale model, all variables such as lift, drag and thrust combination, pitching moment, power input and pressure distribution have been accurately obtained. These tests which included 53 different model configurations were made on two different length channels, with two and three blade propellers of various planforms and blade angles. Tests were also made to determine the effect of placing auxiliary wings of various sizes and arrangements aft of the propeller-wing combination.
