Investigation of Side Forces on Ogive-Cylinder Bodies at High Angles of Attack in the M = 0.5 to 1.1 Range.
Abstract
Side force measurements, involving ogive-cylinder bodies with systematically varied nose fineness and bluntness ratios, are presented for laminar and turbulent boundary layers. Results indicate that the side force remains small below 25 deg angle of attack and increases to a maximum value at around 35 deg to 40 deg depending on Mach number and geometry. The magnitude of side force increases with increasing fineness ratio, and decreases with large nose blunting. Strong dynamic effects and sensitivity to small geometric variations are evident. In all test conditions the measured side force is significantly reduced when the boundary layer is turbulent.
