Abstract:

Hover icing tests were conducted with a UH-1H helicopter. The rotor blade ice shapes obtained in the Canadian National Research Council Icing Spray Rig were documented using steroscopic photography, silicone molds, and cross- section tracings. Power required data were also obtained in an attempt to define the rotor performance degradation caused by icing. A summary of the test effort and ice shape documentation is presented in this report. Additional low-speed performance tests were performed and the results presented.
