Pressure Measurements in the Near Field of a Three Dimensional Delta Wing Model

Abstract

Tests were conducted to determine the near field static pressure signatures created by a 70-deg sweep delta wing model. The model was tested with three leading edges of 0-, 7-, and 11-deg camber and with three leading- edge slot width conditions (0, 0.03, and 0.10 in.). Static pressure signatures were measured with a traversing disk-type pressure probe. A 9-deg half-angle cone was used to generate a flow field through which the disk static pressure probe was traversed for the basic probe calibration. The tests were conducted at free-stream Mach numbers 1.76, 2.00, and 3.00 at model angles of attack of 0 and 6 deg and Reynolds numbers, based on the 10-in. model root chord, from 1, 500,000 to 4,200,000.
