Abstract:

Flight testing of rotorcraft in natural icing conditions is essential to the US Army Airworthiness Qualification requirements and to the US Federal Aviation Administration certification requirements as well as to support research and development efforts. Complete qualificationcertification under natural icing conditions only is very expensive in terms of time due to the limited availability of the required test conditions in the natural environment. Consequently, inflight icing facilities that can duplicate the natural environment as well as extreme test conditions rarely found in natural conditions but necessary to meet Airworthiness QualificationCertification requirements are essential to augment natural icing tests. It is essential that such facilities accurately duplicate the natural environment so that test results can be used for Airworthiness QualificationCertification with a high degree of confidence.
