STATIC PRESSURE ON SHARP AND BLUNT CONES IN CONICAL AND PARALLEL LOW-DENSITY FLOW

摘要

The static pressure distribution on sharp and blunt 10-deg half-angle cones was measured under rarefied conditions in both a uniform and a source flow field. Angle of attack of the cones was varied up to 10 deg. Pressure distributions are presented for cold-wall conditions at 18.0 = or < Mach number = or < 20.3 and 407 < Reynolds number/in. = or < 1272. The source flow results are corrected according to the Newtonian pressure distribution, and the results agree with the uniform flow measurements for the longitudinal distribution at zero angle of attack. Comparisons are made with previous experimental and theoretical results.
