  2. Wind Tunnel Costs • Purdue’s “Quiet” Mach 6 Wind Tunnel • About $10/hour to run • Only 18” (~46 cm) in diameter • 6-8 second runs • NASA’s Glenn Research Center 1’x1’ Supersonic Wind Tunnel • Approximately $34/hour to run • 12” (~30.5 cm) in diameter • 10 discrete airspeeds between Mach 1.3 and 6.0 AAE 450 Spring 2008 Aerothermodynamics and Thermal Loads

  3. Overall Feasibility Check • Scaled-down model • Less than 46 cm in length (30 cm in NASA case) • Less than 2116 cm2 area (929 cm2 in NASA case) • Man-hours • Building and testing model, analyzing results Future Work • Update numbers on size, materials, and cost of model AAE 450 Spring 2008 Aerothermodynamics and Thermal Loads

  4. Backup Slides • Wind Tunnel Comparison AAE 450 Spring 2008 Aerothermodynamics and Thermal Loads
