description abstractMeasurements of base pressure are presented for 29 blunttrailing-edge wings having an aspect ratio of 3.0 and various airfoil profiles. The different profiles comprised thickness ratios between 0.05 and 0.10, boat tail angles between 2.90 and 200, and ratios of trailing-edge thickness to airfoil thickness between 0.2 and 1.0. The tests were conducted at mach numbers of 1.25,1.5,2.0, and 3.1. For each mach number, the Reynolds number and angle of attack were carried. The lowest Reynolds number investigated was 0.2 X106 and the highest was 3.5X106. Measurements on each wing were obtained separately with turbulent flow and laminar flow in the boundary layer. Spanwise surveys of the base pressure were conducted on several wings.
