Icing Simulation in the Aeropropulsion Systems Test Facility Propulsion Development Test Cell C-2
Abstract
The AEDC Propulsion Development Test Cell C-2 has been modified to provide simulated altitude icing conditions. Spray droplet clouds with droplet mass median diameters simulating natural icing clouds are produced with calibrated water atomizing spray nozzles. The proper amount of liquid water ingested by an engine in flight through icing clouds is simulated by injection of the proper water content into the airstream that enters a test engine. The addition of the icing simulation spray system provides the opportunity to conduct simulated icing testing in the large engine test cell. The system is capable of providing icing testing of large engines, inlets, windshields, wings, and other full-scale test articles. The results of system activation testing have been summarized. The system can be used to initiate clouds and reach steady controlled spray operation within 10 sec. The system is capable of varying the LWC over a five-to-one range within 10 sec. The simulation spray can be terminated within 5 sec. The uniformity of the distribution of the supercooled water at the test section has been determined. The transient response of the spray system and the ability to operate at extreme cold conditions for icing testing are improvements beyond previous AEDC icing simulation system capabilities.
