Abstract
Anti-icing methods and aerodynamic structures having laminated resistive heaters for de-icing are described. Several of the inventive aspects utilize laminated resistive heaters comprising a carbon nanotube layer and/or capacitors to store and supply electricity. The invention also includes methods of making aerodynamic structures having de-icing or anti-icing functionality.
Claims17
An airfoil, comprising:
- a channel in a surface of the airfoil wherein a surface of the channel is coated with an electrical insulator and an electrical lead is disposed in the channel;
- wherein the electrical insulator electrically insulates the airfoil from the electrical lead;
- wherein the electrical insulator does not completely surround the electrical lead over the length of the channel;
- wherein the electrical insulator is open on top of the channel area allowing for the electrical lead to contact a CNT-containing resistive heating layer, and wherein the CNT-containing resistive heating layer contacts the electrical lead in the channel;
- and
- further comprising a second electrical lead in electrical contact with the CNT-containing resistive heating layer;
- wherein the CNT-containing resistive heating layer is disposed between the electrical leads and wherein, during operation, the electrical leads power the CNT-containing resistive heating layer.
