AN EXPERIMENTAL INVESTIGATION OF SIMPLE SYMMETRIC AND UNSYMMETRIC SUPERSONIC RING WING CONFIGURATIONS UTILIZING BENEFICIAL INTERFERENCE EFFECTS.
Abstract
The work considers both symmetrical and unsymmetrical configurations, but is generally limited to those employing conical noses and conical boattails. A simplified semi-empirical method for calculating the inviscid pressure distributions over symmetrical configurations is developed. Results of the experimental program demonstrate that very significant drag reductions (of the order of 50 per cent) can be obtained even with simplified ring wing-body combinations. Beneficial interference effects are found to be only gradually reduced as the Mach number varies from the design Mach number or as the angle of attack is increased. Certain possible applications of the ring wing are suggested. (Author)
