本文对F-27飞机机身周围选定位置的气流速度和云液态水含量进行了测量。远离螺旋桨入流区的气流测量值与第一部分中计算的气流测量值相当一致。液态水的测量是使用两个CSIRO热线探头进行的，其中一个可以定位在距离机身15-60厘米的地方。这些比较的结果表明，在第一部分中计算的增强系数似乎是相当合理的，因此可以进行修正，以便考虑到由与机身有关的流场畸变引起的取样误差。比较还表明，有高达10%的额外的采样误差，这取决于相对于机翼和螺旋桨的探头的位置。对于F-27，这些附加效应随着飞机速度的增加而显著减小。
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.
