AN ELECTRIC RESISTANCE AIR HEATER FOR A LOW DENSITY WIND TUNNEL

reportActive / Technical Report | Accession Number: AD0272007 | Need Help?

Abstract:

An electric resistance air heater for wind tunnel 4 of the Aeronautical Sciences Laboratory at the University of California was constructed and proven satisfactory in performance tests. The heater increased the range of stagnation temperature to 1600 F, thereby increasing the experimental range of test conditions of the wind tunnel to include higher Mach numbers, deeper penetration of the slip flow region, and temperatures more nearly simulating free flight conditions.
