ResumoDistortion of airflow around aircraft bodies can affect measurements made from these airborne platforms. In particular, particle sizes and concentrations can be in error, and ice crystals incorrectly classified as a result of flow field distortion. The magnitude of distortion has been evaluated for airflow around wingtip-mounted particle measuring probes on a Beechcraft King Air. The flow field in front of the probes was measured with a five-hole pressure probe during wind tunnel and airborne tests. Results from these tests show significant flow distortion and partially explain the preferred orientation of ice crystals which has been observed in previous measurements.
