| Summary: | An MC-130E instrumented by AFGL for cloud physics research flew a series of tests behind a KC-135 specially modified with a multi-element spray nozzle. The tests, for Air Force Flight Test Center, were to sample and define the spray plume produced by the nozzle at specified values of water flow rate, distance from nozzle, and temperature. PMS spectrometers were used to sample the artificial cloud. Data were analyzed to produce sample average and instantaneous (1 sec) particle size spectra with liquid water content values. Comparison of values of liquid water content, water flow rate, and distance from nozzle to instrument indicate well defined linear relationships. Instantaneous (1 sec) liquid water content values indicate a variance in the uniformity across the spray. Maximum, minimum, mean, and standard deviation values are provided for each sample to characterize the variance. Although many of the particles had round shapes, it was not possible to tell from the instrumentation whether the particles were ice or water drops. (Author) |
