Re-Entry Vehicle Base Pressure and Heat-Transfer Measurements at Mm = 18

Abstract

Nomenclature h — static enthalpy H =• total enthalpy M = Mach number Nu — Nusselt number p — static pressure Pr = Prandtl number q = heat flux r — base coordinate measured from base outer edge R = base coordinate measured from base centerline RB, RN = base and nose radius, respectively RK/RB — bluntness ratio Re = Reynolds number St — Stanton number V = velocity y = ratio of specific heats 6C = cone half-angle p = static density
