Definitions

  • Ice adhesion to certain surfaces causes many problems. For example, excessive ice accumulation on aircraft wings endangers the plane and its passengers. Ice on ship hulls creates navigational difficulties, the expenditure of additional power to navigate through water and ice, and certain unsafe conditions. The need to scrape ice that forms on automobile windshields is regarded by most adults as a bothersome and recurring chore; and any residual ice risks driver visibility and safety.
  • the wire electrodes of a composite coating are connected to a DC bias source so that they have the same DC bias.
  • the surface on which the composite coating is applied is electrically conductive and has an opposite DC bias. Ice formed in the spaces of the composite coating close the electrical circuit.
  • a wire mesh comprising electrically conductive wires is formed.
  • the wire mesh is disposed on an electrically conductive surface, with an insulating layer interposed between the wire mesh and the surface.
  • a DC bias is applied to the wire mesh and an opposite DC bias is applied to the surface. Ice that is formed in the spaces of the wire mesh closes the electrical circuit.
  • the invention takes the form of a composite cloth, it contains both the functional anodes and cathodes necessary for the system to work. Therefore, it is not important whether the surface of the object to be protected is electrically conductive or nonconductive.
  • FIG. 5 depicts a wire mesh in accordance with the invention.
  • FIG. 1 shows one system 10 incorporating an electrical deicing coating 12 to affect ice 14 that might adhere to surface 16.
  • Surface 16 may for example be an airplane wing, helicopter blade, jet inlet, heat exchanger for kitchen and industrial equipment, refridgerator, road signs, ship overstructures, or other object subjected to cold, wet and ice conditions. More specifically, coating 12 is applied over surface 16 to protect surface 16 from ice 14. Coating 12 is preferably flexible so as to physically conform to the shape of surface 16.

Abstract

L'invention concerne un système permettant de modifier la force d'adhésion de la glace sur un objet. Ce système comprend un revêtement composite contenant des fils-électrodes recouvrant la surface à protéger. Dans un mode de réalisation, un revêtement composite contient des fils-électrodes et des fibres d'isolateur. Le revêtement composite est appliqué sur la surface d'un objet sur lequel la force d'adhésion de la glace doit être modifiée. Les fils-électrodes, qui sont connectés sur une source de polarisation en courant continu, fonctionnent de manière alternée comme des cathodes et des anodes. La source génère une polarisation en courant continu dirigée sur une interface entre la glace et la surface lorsque la glace a parcouru le circuit séparant les fils de l'anode et de la cathode. Dans un autre mode de réalisation, un treillis métallique est disposé sur une surface électroconductrice de l'objet et des polarisations opposées en courant continu sont appliquées sur le treillis et sur la surface. Dans un autre mode de réalisation, le revêtement comprend des fils d'anode et de cathode tissés au moyen de fibres d'isolateur de manière à former un tissu composite appliqué sur la surface pour protéger cette dernière contre la glace.
