8-Foot High-Temperature Tunnel Facility
The 8-Foot High Temperature Tunnel (HTT) provides combustion-heated hypersonic blowdown-to-atmosphere simulation for Mach numbers of 3, 4, 5, and 6.5 through a range of altitude from 50,000 to 120,000 feet.
Focus Areas and Capabilities
Learn more about the specifications and capabilities of this facility.
Characteristics
The facility test stream is produced by burning methane, air, and liquid oxygen and expanding the combustion products through any one of several nozzles in to the test section.
Quick Facts
It has an array of test support systems: hydrogen system, silane system, JP–7/JP–10 systems, ethylene system, model hydraulic system, water cooling systems, and nitrogen purge systems.
Data Acquisition
The facility currently provides testing capability at Mach 3, 4, 5, and 6.5. The test section accommodates very large (5 by 9 ft) thermal protection system models.

Fact Sheet
The 8-Foot High-Temperature Tunnel (HTT) is the nation’s largest hypersonic blow down test facility.
The facility supports large-scale thermal protection system testing, flight qualification testing, and hypersonic engine testing. The HTT duplicates as near as possible, the flight conditions that would be encountered by hypersonic vehicles in the atmosphere.
