Correlation of Two Experimental Methods of Determining Characteristics of Unswept Wings

Abstract

Comparison is made of two methods used to measure derivatives resulting from flow, the first providing for forced rotation of model in a straight air stream and the second for rotation of air stream with model fixed. Wind-tunnel tests were conducted on a tapered wing and rectangular wings of different span to obtain correlation between the two methods of testing. The consistent agreement of results obtained for rolling characteristics indicates that, for unswept wings, the rolling-flow test procedure should be satisfactory.
