Aircraft Flow Effects on Cloud Droplet Images and Concentrations (Les Effets D'Ecoulement d'air Autour d'une Avion sur les Images et les Concentrations Mesurees de Gouttelettes dans les Nuages)

Abstract

Cloud physics measurements by the Twin Otter aircraft are affected to some degree by local flow effects from the wing and from the probe canister. Droplet images and concentration are distorted in the worst case by no more than 20% for an aircraft lift coefficient (C sub L) of 0.75 and by only a few percent for low values of C sub L. Corrections for a Particle Measuring Systems probe mounted on a short pylon at the inboard spanwise location have been given which are based on an experimentally verified model for the flow velocity.
