The Mach 6 Quiet Tunnel at Texas A&M: Quiet flow performance Conference Paper uri icon

abstract

  • The Mach 6 Quiet Tunnel (M6QT), the hypersonic low-disturbance facility formerly at NASA Langley, has been permanently installed as part of the Texas A&M National Aerothermochemistry Laboratory (TAMU-NAL) in College Station, Texas. The tunnel now operates interchangeably with the Adaptively Controlled Expansion Mach 5-8 tunnel (ACE) in a blowdown configuration with a maximum runtime of approximately 50 seconds. An initial series of tests to determine the quiet-flow capabilities of the nozzle indicate performance largely consistent with its former operation at NASA Langley, with evidence of a full-length quiet test core at stagnation pressures up to 145 psia. Intermittency present in the pressure signals at total pressures above 80 psia is quantified and discussed. In addition, the capability of the tunnel to support future flared-cone experimental models is demonstrated. Copyright 2010 by the American Institute of Aeronautics and Astronautics, Inc.
