Heat Transfer and Pressure Measurement on a 5-inch Hemispherical Concave Nose at a Mach Number of 2.0


Book Description

Abstract: The concave-nose stagnation-point heating is 40 percent of that of a hemisphere nose shape having the same diameter. At angles of attack of ℗±5© and ℗± 10© there is no increase in heating of the nose. Total pressures behind the shock were experienced up to 60© on the concave part for all angles of attack. The tests were made under sea-level conditions for a Reynolds number per foot of about 14 x 106.










Heat-transfer and Pressure Measurements on Flat-faced Cylinders at a Mach Number of 2


Book Description

Flat-faced cylinders of 12-inch dtameter and 4-inch diameter were tested at a Mach number of 2 and sea-level conditions in the preflight jet of the Langley Pilotless Aircraft Research Station at Wallops Island, Va. Both pressure distributions and heat-transfer rates were measured.
