An Investigation into the Ice Build Up on the Nozzle Matrix of the 'Pegasus' Icing Spray System.

Abstract

During the course of flight experiments using an airborne icing spray system fitted to a Nomad aircraft, ice build up on the spray matrix was encountered after prolonged spraying at high liquid water contents at low temperatures. The problem was found to be caused by airflow separation on the fairing to the matrix tubing which induced water droplets back onto the fairing. Tests on a ground icing rig showed that ice build up could be eliminated by redesigning the fairing to prevent the airflow separation. (Author)
