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.
