Abstract
A hypersonic wind tunnel was constructed at the Gas Dynamics Laboratory using air as the working fluid. This tunnel, capable of operating from Mach 5 to 10 at Reynolds numbers per inch of 0.03 to 0.40 million, has a test section diameter of 3 1/4 inches. The key part of the installation is a storage heater which consists of a coul of heavy-walled inconel pipe which is preheated electrically to the desired stagnation temperature. A maximum temperature of 2000 R at a pressure of 1500 psia is generated for running times of 6 to 12 minutes. Preliminary calibration tests using conical nozzles at M = 7 and 10 have verified the basic design and operating range. (Author)
