This report details the development and calibration of a new facility to test medium size rotors for Remotely Piloted Aerial Systems (RPAS) under in-flight icing conditions. This facility has made use of a 3 m x 6 m cold room at the Montreal Road campus of the NRC and includes a spray bar system to provide the icing cloud as well as a dedicated rotor stand assembly that incorporates a load cell and dynamometer. Calibration data of the spray drop sizes and liquid water content are provided and compared to conditions of the natural environment as detailed in icing regulations for transport category airplanes, i.e., CFR 14 Part 25 Appendix C and O. Example data of performance of a medium size rotor under icing conditions are provided and compared to previous data collected on smaller rotors in a different icing facility at the NRC. |
