Initial Calibration of the HEAT-H2 Arc-Heated Wind Tunnel
Abstract
An arc-heated wind tunnel added to the test facility inventory can provide a large free-jet (up to 42 in. diam at the nozzle exit) hypersonic flow. The tunnel, designated HEAT-H2, is capable of true temperature, true pressure simulations at speeds up to 15,000 ft/sec and altitudes up to 165,000 ft. Flow Mach numbers from 4 to 8 can be achieved with the existing nozzles. Included herein is a description of the test facility, along with initial calibration results obtained from one nozzle/throat combination. The calibration was performed using a 1.5-in.-diam throat and a 24-in. exit diam, 8-deg half-angle conical nozzle. Arc heater chamber conditions ranged from 32 to 66 atm pressure, with total enthalpy from 1,560 to 2.160 Btu/lbm. Measurements within the free jet included distributions of pitot pressure, total enthalpy, and flow angle. Surface pressure distributions on a blunt cone were also obtained.
