PRESSURE DISTRIBUTION AND PRESSURE DRAG FOR A HEMISPHERICAL NOSE AT MACH NUMBERS 2.05, 2.54, AND 3.04

摘要

An experimental investigation of the pressure distributions on a hemispherical nose 3-98 inches in diameter, mounted on a cylindrical support, has been made at Mach numbers of 2.05, 2.54, and 3.04 and for Reynolds numbers of 4.44 x 106, 4.57 X 106, and 4.l6 x 106, respectively. The Reynolds number was based on body diameter and free-stream conditions. Pressure-drag coefficients were calculated and good agreement was obtained between these tests and other investigations.
