Instrumentation systems for the Langley Research Center 8-foot high temperature tunnelA description is presented of the 8-foot high-temperature tunnel, a Mach 7 blowdown-type facility in which methane is burned in air under pressure, with the resulting combustion products utilized as the test medium. The instrumentation environment and requirements are identified, and instrumentation design, including wiring, sensors, and data acquisition system are described. The design and installation of a fast oxygen monitoring system to maintain the partial pressure of oxygen at 21 percent in the tunnel test section is included. Also, the new data acquisition system hardware details and data-reduction capabilities are defined.
