Abstract: A heat transfer calibration plate for use in obtaining data for determining the heat transfer coefficient in a wind tunnel test system having a copper plate mounted in an aluminum support plate. Nine heat flux gages are positioned in a horizontal and a vertical row with a center gage common to the two rows. A heater is provided to heat the plate to the desired temperature. Thermocouples are provided to indicate plate temperature. Outputs of the thermocouples and heat flux gages are recorded on a recorder. All of the heat flux gages except the center gage are connected to the recorder through a rotary switch. Plenum temperature and pressure are also recorded.

Abstract: A test sample support for flat plate test samples used in the simultaneous laser, wind tunnel and tensile machine testing having a cantilever box frame member supported on the tensile machine with an adjustable sample alignment member and a stationary sample alignment member supported on the box frame member. Test sample backing members are adjustably supported on box frame member adjacent the stationary sample alignment member and on the adjustable sample alignment member. Two sample retainer buttons are secured to the stationary sample alignment member and two sample retainer buttons are secured to the adjustable sample alignment member. The stationary sample support member is positioned upstream of the test sample and has a sharp leading edge to provide a well defined flow field over the test sample.
