Abstract:

A preliminary investigation was conducted in a 4,000 F supersonic air jet at a Mach number of 2 at the Langley Aeronautical Laboratory to investigate the behavior of Be and BeCu. Both materials were tested as conical models having 10 degree half-angles with sharp points and with 0.064-in. nose radii. Results of these tests indicate that the Be is superior to BeCu as a heat-sink material. No burning of either material was observed during the test. Author
