Abstract
An erosion shield assembly includes an erosion shield, a carbon allotrope heater attached to an inner surface of the erosion shield, and an adhesive layer between the carbon allotrope heater and the erosion shield. The carbon allotrope heater includes at least one layer of a carbon allotrope material.
Claims16
An erosion shield assembly comprising:
- an erosion shield configured to form to a leading edge of an aircraft surface;
- a carbon allotrope heater attached to an inner surface of the erosion shield, the carbon allotrope heater comprising:
- at least one layer of a carbon allotrope material;
- a first region having a first electrical resistance;
- and
- a second region abutting the first region and having a second electrical resistance lower than the first electrical resistance;
- and
- an adhesive layer between the carbon allotrope heater and the erosion shield;
- wherein electrical components of the first region of the carbon allotrope heater are arranged as a circuit in series to provide the first electrical resistance;
- and
- wherein electrical components of the second region of the carbon allotrope heater are arranged as a circuit in parallel to provide the second electrical resistance.
