Determination of Rate, Area, and Distribution of Impingement of Waterdrops on Various Airfoils from Trajectories Obtained on the Differential Analyzer

NACA Research Memorandum (RM No. 9A05, February 1949) in which University of California researchers use a differential analyzer to solve the differential equations of waterdrop motion around Joukowski airfoils. Trajectories are computed for three airfoil/angle-of-attack cases, yielding the rate, area, and distribution of waterdrop impingement as functions of two dimensionless moduli; results are compared with impingement data for cylinders. The work demonstrates the differential analyzer as a practical tool for aeronautical icing calculations otherwise requiring laborious numerical integration.
