Abstract:

A temperature probe using a platinum hot-wire which can be used to measure the local stagnation temperature in a hypersonic boundary layer was designed and tested. The temperature dependence of the wire properties is taken into account which greatly extends the probes operating range. The primary function of the probe is to measure the temperature profiles in the sublayer. The small wire size 0.0001 inches and suitable probe design make it possible to make measurements to within 0.003 inches of the wall. Author
