A further investigation of the meteorological conditions conducive to aircraft icing

Abstract

Meteorological datafromflight observations la icing conditions during thewinterof 19k.&k7 arepresented, Dataon liquid watercontent, temperature, andmea-f fective dropMameterare shown to be consistent withvalues previously propoeed formaximum icingconditions.Dataon dro~ize dietrilnztion as oh%inedby therotatin~ylinder method, ,although consistent withmeasurements previously ~de, werefoundto be inconsistent withdataon drop sizeM.stributionderived fromtheratioof thenaximum diameter to theme~ffecttve di~ter whenWe maximum diameter was calculated frantheareaof impingement on a stationary cylind6r.Therelation between temperature and~xim~liqul(l watercontent in,~yerclouds is discussed andestimates aregivenforthe higheqt values ofwatercontent to be expected in layerclouds at various 'temperatures."
