Abstract:

The US Army requires the UH-60A helicopter Black Hawk to operate safely in an icing environment up to and including the moderate level of intensity. Artificial icing tests were previously conducted in Alaska in 1976 by the United States Army Aviation Engineering Flight Activity USAAEFA using a prototype YUH-60A with main and tail rotor deice system and anti-ice provisions for the pilot and copilot windshields, pitot-static tubes and their support struts, engines, and engine inlets. The objectives of this test are to conduct artificial and natural icing flight tests of the production UH-60A helicopter to Substantiate the effectiveness of the production anti-icedeice systems Determine the effectiveness of the ice detection subsystem Evaluate the effect of ice accumulation on handling qualities and performance. The anti-icedeice systems will be operating for all tests in the icing environment Provide data for inclusion in the operators manual.
