First Stage of Equipping a Do 28 as a Research Aircraft for Icing, and First Research Results

摘要

A Do 28 aircraft was equipped for measuring liquid water content, LWC (2 types of instrument), temperature, relative humidity, backscatter coefficient, and ice accretion (on 3 different standard cylinders). During winter flights, the thickness of ice accretion on the standard cylinders increases linearly with LWC between an LWC of 0.06 and 0.30 g/cum; the thinner the cylinder, the thicker the ice accretion; ice accretion increases significantly with a drop in temperature of only a few degrees; good agreement is shown between 2 different types of instruments for measuring LWC.
