Columbia: The first five flights entry heating data series. Volume 3: The lower windward surface centerline

Entry heating flight data and wind tunnel data on the lower surface centerline are presented in terms of normalized film heat transfer coefficients as a function of angle-of-attack, Mach number, and Normal Shock Reynolds number. The surface heating rates and temperatures were obtained via the JSC NONLIN/INVERSE computer program. Time history plots of the surface heating rates and temperatures are also presented.
