LAMINAR HEAT-TRANSFER AND PRESSURE-DISTRIBUTION STUDIES ON A SERIES OF REENTRY NOSE SHAPES AT A MACH NUMBER OF 19.4 IN HELIUM
Abstract
An experimental investigation was conducted in the 2-in. helium tunnel at the Langley Research Center at a Mach number of 19.4 to determine the pressure distributions and heat-transfer characteristics of a family of reentry nose shapes. The pressure and heat-transfer-rate distributions on the nose shapes are compared with theoretical predictions to ascertain the limitations and validity of the theories at hypersonic speeds. The experimental results were found to be adequately predicted by existing theories. Two of the nose shapes were tested with variable-length flow-separation spikes. The results obtained by previous investigators of spike-nose bodies were found to prevail at the higher Mach number of the present investigation. (Author)
