Support Interference on an Ogive-Cylinder Model at High Angle of Attack in Transonic Flow

Abstract

A combined experimental and analytical study was conducted to determine the relative magnitude of the support and tunnel wall interferences on an ogive-cylinder model at a high angle of attack in transonic flow. The tests were conducted in the AEDC Aerodynamic Wind Tunnel (4T). The results indicate that the strut support causes large reductions in the normal force on the model, while the effect attributable to the sting support is much smaller. A correction procedure applied to the data to remove support interference gives consistent results. The test data, combined with an inviscid analytic study, indicate that the wall interference effects were negligible. Solutions obtained using two computational methods compare well with experimental results.
