Wind Tunnel Calibration of a PMS (Particle Measuring Systems) Canister Instrumented for Airflow Measurement.
Abstract
Measurements of cloud particle images and concentrations using laser spectrometers housed in pods mounted on the wings or fuselages of research aircraft can be affected by the distortion of the airflow about the aircraft. The Flight Research Laboratory has developed a pod with a Rosemount 858 5-hole probe and pressure transducers to measure airflow angles and velocities at typical mounting locations on cloud physics research aircraft. This report documents the results of an extensive wind tunnel calibration of this pod to determine the factors relating the differential pressure measurements to the flow angles and velocities, and in particular to account for the effects of the canister itself on these measurements.
