An Investigation of Anti-Icing Endurance Times of Aircraft Ground De/Anti-Icing Fluids: Snow Pellets, Thermodynamic and Aerodynamic Fluid Failure and Non-Glycol Fluids

The purpose of this research is to (1) develop, validate, and document experimental methods for the determination of holdover times for snow pellets using the cold room generated snow pellets, (2) understand, develop, and validate a thermodynamic model to predict the failure of a fluid by snow and identify the sensitive parameters, (3) compare holdover times for snow pellets for de-icing fluids, (4) run wind tunnel tests on contaminated fluids, (5) correlate the thermodynamic failure to the aerodynamic failure, and; (6) develop a more representative series of tests with non-glycol fluids to evaluate the potential problems before their use on aircraft.
