Abstract : A temperature probe using a small thermocouple wire with its axis placed normal to an airstream was designed, built and tested. The primary purpose of the probe is to measure the stagnation temperature distribution through a supersonic turbulent boundary layer. The small probe size permits measurements in the laminar sublayer region. The probe's simple geometric shape and design provides simplicity in determining the local gas temperature. Experiments were made to measure the local stagnation temperature of the flow with an accuracy of 5R over a moderate temperature range of 560R to 780R. (Author)
