Abstract
A wall for a heated faceplate includes a base and tines protruding from the base and spaced from each another. The tines are configured to accumulate ice in a manner which promotes shedding of small ice formations to prevent large accumulations of ice father aft on the faceplate.
Claims18
A wall for a heated faceplate comprising:
- a base configured to connect to an exterior surface of the heated faceplate;
- and
- tines spaced from each another and protruding out and away from the base so that the tines overhang the base in an upstream direction such that the tines are configured to accumulate ice and shed the accumulated ice.
A faceplate comprising:
- an interior surface configured to face toward an interior of an aircraft;
- an exterior surface opposite the interior surface;
- and
- a wall connected to the exterior surface of the faceplate at an upstream portion of the faceplate;
- the wall including:
- a base connected to the exterior surface of the faceplate at the upstream portion of the faceplate;
- and
- tines protruding from a top of the base, wherein the tines are substantially parallel to oncoming airflow.
5 more elements
A faceplate comprising:
- an upstream portion;
- a downstream portion adjacent the upstream portion;
- and
- a wall at the upstream portion of the faceplate;
- the wall including:
- a base connected to an exterior surface of the faceplate at the upstream portion of the faceplate;
- and
- tines protruding from the base, wherein the tines are substantially parallel to oncoming airflow;
- wherein the faceplate is a faceplate for an angle of attack sensor.
6 more elements
A faceplate comprising:
- an upstream portion;
- a downstream portion adjacent the upstream portion;
- and
- a wall at the upstream portion of the faceplate;
- the wall including:
- a base connected to an exterior surface of the faceplate at the upstream portion of the faceplate;
- and
- tines protruding from the base, wherein the tines are substantially parallel to oncoming airflow;
- wherein the faceplate is a faceplate for a flush static plate.
6 more elements
A method for preventing significant ice accumulation on a heated faceplate comprising:
- accumulating ice fragments on tines protruding from a base of a wall at an upstream portion of the faceplate, wherein the wall is connected to an exterior surface of the faceplate, the exterior surface being opposite an interior surface that is configured to face toward an interior of an aircraft;
- and
- shedding the ice fragments from the tines.
