B. Anti-ice System
(1) The anti-ice system is controlled by the pilot via a
cockpit mounted rheostat. This rheostat operates
a pump that pumps anti-ice fluid from the tank at a
controlled rate.
(2) 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. 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
which are welded to the slinger ring, and then out onto
the blade anti-icing boots.
(3) The blade anti-icing boots are ridged rubber sheets that
are glued to the leading edge of the blades. The ridges
in the anti-icing boots direct the fluid out onto the blades
and permit for an even distribution of the anti-ice fluid
across the blades.
