Zusammenfassung: | A stagnation temperature probe with a single platinum-coated silica shield was built for use at high supersonic speeds and elevated temperatures. For large Reynolds numbers the temperature recovery factor of the probe reaches 0.998. It decreases with decreasing Reynolds number and increasing temperature. At temperatures up to 700° K the major thermometric losses of the probe are conduction losses. One single calibration curve is obtained for any one probe by relating the calibration data to the flow conditions inside the probe. |
