Abstract
Measurements have been made of airflow velocities and cloud liquid water contents from selected positions around the fuselage of an F-27 aircraft. The airflow measurements away from the propeller inflow region are in reasonable agreement with those calculated in Part I. The liquid water measurements were made using two CSIRO hot-wire probes, one of which could be positioned at distances of 15–60 cm from the fuselage. Results of these comparisons showed that the enhancement factors calculated in Part I appear quite reasonable and that corrections can consequently be made to allow for sampling errors caused by fuselage-related flow distortions. The comparisons also show that there are additional sampling errors as large as 10% which depend on position of the probe relative to the wings and propeller. For the F-27 these additional effects decrease substantially with increasing aircraft speed.
