"The presence of radomes and instruments that are sensitive to water films or ice formations in the nose section of all-weather aircraft and missiles necessitates a knowledge of the droplet impingement characteristics of bodies of revolution."
Summary
Water-drop impingement on several bodies of revolution is quantified.
Discussion
NACA-TN-4092 4 notes:
The impingement characteristics of bodies of revolution are of interest because such bodies are representative of many aircraft components subject to icing such as radomes, body noses, engine accessory housings, and the large spinners of turboprop engines.
NACA-TN-3099 1 is the first in a series and has a rather complete description of the analysis methods, so the discussion below refers to that, unless noted otherwise.
Flow field
Potential flow can be determined in 2D radial coordinates as well as 2D Cartesian coordinates. This was used to assess several geometries.
