Summary of Artificial and Natural Icing Tests Conducted on U.S. Army Aircraft from 1974 to 1985
Abstract
The U.S. Army Aviation Systems Command (USAAVSCOM) conducts airworthiness qualification testing on aircraft under artificial and natural icing conditions. A JCH-47C helicopter with Helicopter Icing Spray System (HISS) installed is used for generating a simulated natural icing environment. The artificial icing tests are followed by natural icing tests to assure a wide variety of flight conditions are tested and to verify artificial icing test results. The JCH-47C/HISS has been used since 1974 for conducting research, engineering, development, and qualification testing for U.S. Army, Navy, NASA, and various contractor aircraft. The USAAVSCOM has compiled an extensive artificial and natural icing test data base which is summarized in this report. This report documents unclassified U.S. Army, other U.S. Government agencies, and commercial icing test programs. Also discussed is the use of deice and anti- ice systems; the impact of ice accretion and shedding characteristics, performance considerations, stability and control, and vibration characteristics; and the cloud parameters measurement equipment and test aircraft instrumentation used for documenting test data. The test methodology and requirements used for qualifying aircraft for flight into icing conditions, instrumentation, and special equipment are summarized, and the details for test conducted are contained in the references. The report documents, in part, 14 years of U.S. Army experience in conducting in-flight aircraft icing tests.
