Abstract
An anti-ice system including means for removing water from a heated ice prone surface before the water reaches a surface downstream of the ice-prone surface. In one embodiment, the means comprises an eductor connected to the ice-prone surface. In another embodiment, the means comprises a mechanical pump connected to the ice-prone surface. Examples of the ice-prone surface include an engine inlet or an aero-surface on an aircraft.
Claims20
An apparatus, comprising:
- an anti-ice system, comprising:
- an eductor including:
- a channel including an inlet and an outlet;
- and
- a nozzle connected to the channel;
- and
- at least one aircraft part including an ice-prone surface, the ice-prone surface including the inlet, wherein a flow of pressurized air into the channel from the nozzle suctions water off the ice-prone surface through the inlet and into the outlet, so as to remove the water before the water freezes downstream of the ice-prone surface.

A method of removing water from an ice-prone surface, comprising:
- suctioning water from an ice-prone surface using an eductor, comprising a nozzle and a channel connected to the nozzle, wherein the channel includes an outlet and an inlet in the ice-prone surface;
- and
- providing a flow of pressurized air through the nozzle and into the channel, wherein the flow of pressurized air creates a low pressure P in the inlet that draws the water through the inlet so as to remove the water from the ice-prone surface.
An anti-ice system, comprising:
- an engine inlet comprising a lip and an opening;
- and
- an anti-ice system comprising:
- a mechanical pump, or
- at least one eductor including:
- a channel including an outlet and the opening comprising an inlet;
- and
- a nozzle connected to the channel, wherein a flow of pressurized air into the nozzle creates a low pressure P that draws water into the channel through the inlet;
- and
- a covering on the opening allowing the water to pass through into the channel or the mechanical pump, the covering comprising a grid, a slot, or a porous material;
- and wherein
- the anti-ice system removes the water from the lip before the water reaches a surface downstream of the engine inlet.
