DESIGN PERFORMANCE AND OPERATIONAL CHARACTERISTICS OF THE ARL TWENTY-INCH HYPERSONIC WIND TUNNEL

Abstract

The ARL 20-in. Hypersonic Wind Tunnel is a blowdown type, free-jet installation that can deliver air at Mach numbers from 8 to 14 at free stream Reynolds numbers of 1 to .03 times 10 to the 7th power per foot. The report discusses some of the initial considerations influencing the configuration of the facility and presents theoretical performance estimates of its aerodynamic components; i.e., the electric resistance heater, the nozzle, the diffuser and the vacuum supply. Operational characteristics such as mass flow rates, electric power requirements, sphere evacuation rates, etc., are also treated for the full range of Mach numbers. Brief discussions on the extension of testing time and on the character of the delivered air flow are included. Mechanical design, control systems, and wind tunnel instrumentation of the facility are not considered.
