26 (This page is intentionally blank.) DESCRIPTION AND OPERATION Page 2-2

27 1. Description of an Anti-Ice System A. The propeller anti-ice system prevents formation of ice on propeller surfaces. An anti-ice system dispenses a fluid that mixes with the moisture and decreases the temperature that will cause the moisture to freeze on the propeller blades. The mixture may flow off the blades before it forms ice. 2. Components of an Anti-ice System A. Anti-icing Boot (1) The blade anti-icing boots are channeled rubber sheets that are securely attached to the leading edge of each blade with adhesive. The ridges in the anti-icing boot direct the fluid out onto the blades and permit for an even distribution of the anti-icing fluid across the blades. B. Feed Tube (1) Feed tubes are installed on the propeller hub and adjusted to dispense fluid along the leading edge of the propeller anti-icing boots. C. Fluid Tank (1) Reservoir for anti-ice fluid. D. Pump (1) The pump supplies anti-ice fluid from the tank at a controlled rate. The anti-ice fluid is delivered through a filter, a check valve, and then through tubing to a slinger ring located at the rear of the spinner bulkhead. E. Slinger Ring (1) The anti-ice fluid is dispensed into the rotating slinger ring, which holds the fluid in a curved channel by centrifugal force. The fluid then flows out of the slinger ring through feed tubes that are connected to the slinger ring, and then out onto the blade anti-icing boots. DESCRIPTION AND OPERATION Page 2-3
