Abstract:

A limited test is reported of a Thermo-Systems Inc Series 1050 constant-temperature hot-film anemometer system in the Lockheed-California Company icing research tunnel to determine its suitability as a detector of discrete water droplets and liquid water content in natural and artificial icing clouds. It was determined that the hot-film anemometer was capable of recording individual but that the signal processing equipment required modification to prevent errors due to noise, saturation, and frequency response. Recommendations include improved signal processing electronics and precautionary procedures to enhance anemometer survivability.
