The construction and installation of the tunnel was completed. The report describes in detail the mechanical, electrical, and instrumentation features of the tunnel. Emphasis is placed on those aspects that are unique for a true temperature hypersonic wind tunnel installation. Special data acquisition instrumentation is described. The tunnel operational regime covers Mach numbers from 4.5 to 11 at supply air pressures from 10 to 68 atmospheres and stagnation temperatures from 2000 to 6000K. Unit Reynolds numbers range from 3000 to 2,000,000 per foot. Results of tunnel shakedown and limited calibration tests are discussed. It was found that all components perform quite well and that tunnel conditions are reproducible with good accuracy. Author
