Weeping ferrofluid anti-ice system

Abstract:

Method, system, and aircraft for providing anti-ice protection including a supply of ferrofluid that is flowed out of orifices along a first region of an aerodynamic surface. The flowed ferrofluid is urged toward an aperture on a second region. The aperture is arranged relative to a magnetic field generator. A magnetic field generated by the magnetic field generator attracts the ferrofluid into the aperture while water droplets carried by the ferrofluid continue past the aperture.
