The 8-Foot High Temperature Tunnel (HTT) simulates true enthalpy at hypersonic flight conditions for testing advanced, large-scale, flight-weight aerothermal, structural, and propulsion concepts. The facility provides combustion-heated hypersonic blowdown-to-atmosphere simulation for Mach numbers of 4, 5, and 7 through a range of altitude from 50,000 to 120,000 feet.
Speed: Mach 3, 4, 5, and 6.5
Reynolds Number: 0.44 – 5.09 x 106 per ft. [Mach dependent]
Pressure: 50-3,500 lbs. per sq. in. [Mach dependent]
Test Gas: Ambient atmosphere / methane mix
Test Section Size: 8-foot diameter
Length: 12 feet
Drive Power: 12,000 horsepower
