Abstract
An ice protection system may include a blade and an electrothermal heater including a carbon nanotube (CNT) element and a metal element. The CNT element may be a CNT fabric or a CNT yarn. The metal element may be coupled to the CNT element via a metallization process, or the like. The electrothermal heater element may include an electric sheet resistivity between 0.01 and 0.5 ohms/square.
Claims20
An ice protection system comprising:
- an electrothermal heater configured to receive a current from a power source, the electrothermal heater comprising a first plurality of metallized carbon nanotube (CNT) elements in disposed in a first direction and a second plurality of metallized carbon nanotube (CNT) elements in a second direction.
A blade assembly, comprising:
- an airfoil including a leading edge, a trailing edge, a pressure side and a suction side, the pressure side extending from the leading edge to the trailing edge, the suction side extending from the leading edge to the trailing edge;
- and
- an ice protection system disposed on at least one of the leading edge, the pressure side, and the suction side, the ice protection system comprising an electrothermal heater coupled to the airfoil, the electrothermal heater comprising a carbon nanotube (CNT) fabric and a metal coating at least partially infiltrating pores of the CNT fabric.
A blade assembly comprising:
- an airfoil including a leading edge, a trailing edge, a pressure side and a suction side, the pressure side extending from the leading edge to the trailing edge, the suction side extending from the leading edge to the trailing edge;
- and
- an ice protection system disposed on at least one of the leading edge, the pressure side, and the suction side, the ice protection system comprising an electrothermal heater coupled to the airfoil, the electrothermal heater comprising a carbon nanotube (CNT) yarn and a metallic coating disposed around an outer surface of the CNT yarn.
