Abstract:
1. An electro-expulsive de-icing actuator comprising: a first subassembly comprising: a second subassembly comprising: wherein the first and second subassemblies are mechanically independent; at least one separate electrically conductive connector connecting a second end of the first electrically conductive element of the first subassembly to a corresponding second end of the second electrically conductive element of the second subassembly, thereby creating a conductive path from the electrical input to the electrical output; wherein the first and second subassemblies are disposed in an orientation such that an electrical current flows in a single first direction along a single longitudinal axis of the actuator through the first subassembly and in a single opposite, parallel direction along the single longitudinal axis through the second subassembly such that when electrical current flows through the conductive path, at least a portion of each of the first and second subassemblies move apart relative to one another as a result of the magnetic fields created by the electrical current in the first and second subassemblies; and wherein the at least one connector is configured to allow the second end of the first subassembly and the second end of the second subassembly to move apart relative to each other.
