摘要： A heating element is provided with a conductive path pattern which can be printed in a mask-free manner (e.g., drop-on-demand) with existing printing technology. The printing step can be performed, for example, with a thermal inkjet printer, a piezoelectric inkjet printer, an aerosol jet printer, or an ultrasound printer. The ink solution can be formulated so that it establishes an electrically conductive path which is free of polymer binders.

摘要： An electro-thermal ice protection system for an airfoil comprises: a metal foil heater including an integral parting strip, the metal foil heater configurable to cover at least a portion of a leading edge of the airfoil with the integral parting strip disposed along an air-stagnation zone of the leading edge; and a controller coupled electrically to the metal foil heater for controlling electrical energy from a power source to the metal foil of the heater in accordance with a pulse duty-cycle and for controlling power to the parting strip of the heater to maintain the air-stagnation zone virtually free of ice formation. A method of making an exemplary metal foil heater for use in ice protection of an airfoil comprises the steps of: preparing a sheet of Titanium foil in a rectangular shape having a length substantially greater than a width thereof for covering at least a portion of the leading edge of the airfoil; applying a layer of Nickel material over an area along each width edge of the Titanium foil; applying a layer of Copper material over the Nickel layer along each width edge of the Titanium foil; and attaching conductor wires to the Copper layers at each width edge.

摘要： A slip ring assembly having a slip ring holder made of a composite dielectric material reinforced by layers of fabric is molded with the slip rings positioned in the mold, or alternately, grooves are machined in the holder for receiving the slip rings. The holder has at least one flange for mounting the assembly on a rotating part such as a spinner bulkhead of an aircraft propeller assembly. Slip rings are adhered to the composite material of the holder as a result of molding, or use of an adhesive where the grooves are machined in the holder.The metallic wire connections fastened to the slip rings by welding also serve to hold the slip rings in the grooves of the holder. The wire connections may have pins for receiving mating receptacles. Openings in the ends of the metallic wire connections are suitable for crimping wire connectors to the deicers or deicer terminals.
