| 摘要： | The Federal Aviation Administration sponsored a preliminary experimental research program to study the effects of mixed-phase and fully glaciated icing conditions on the performance of thermal anti-icing ice protection systems (IPS). The experimental investigation was limited to a 36-inch chord NACA 0012 airfoil that was equipped with a leading-edge electrothermal ice protection system. The testing was accomplished at the Cox & Company, LeClerc Icing Research Laboratory tunnel, using the laboratory's newly developed capability to simulate mixed-phase icing conditions in their tunnel. Chordwise power required to operate the IPS in the evaporative mode (with an IPS surface temperature of 150 F) and in the running wet mode (with an IPS surface temperature of 50 F) was recorded with a model angle of attack of 0 and with supercooled liquid, mixed-phase, and glaciated conditions at temperatures of 0 and 12 F. Photographic records of the ice accretion and ice protection phenomena, using newly developed optical techniques, were obtained by the National Aeronautical and Space Administration Glenn Research Center Icing Branch. This report describes the test program and summarizes the associated results. |
