Abstract: Flow-induced distortions of water drop flux and speed are predicted by three-dimensional calculations. The instruments are studied in isolation and mounted under the wing of a DeHavilland Twin Otter airplane. Several free ...

Abstract: A three-dimensional first-order panel code is used to calculate airflow around and into the Airborne Snow Concentration Measuring Equipment (ASCME), and an axisymmetric second-order panel code is used to calculate flow to ...

Abstract: Methods that use potential-flow calculations to correct turbulence measurements for instrument-induced flow distortions are discussed in general terms for two- and three-dimensional geometries. A simple calculation method ...

Abstract: The M-meter is designed to measure total mass concentration of hydrometeors from aircraft aloft. Its essence is a free-rotating, vaned disk with face normal to the freestream; rotation is driven by airflow through the ...
