Final answer:
In an electrical anti-icing/de-icing system, a slip ring is used to transfer electrical power from the stationary engine to the rotating propeller without the need for physical wires.
Step-by-step explanation:
In an electrical anti-icing/de-icing system, the problem of transferring electrical power from the stationary engine to the rotating propeller is solved using a slip ring. A slip ring is a conductive element that allows the transfer of electrical power and signals between a stationary and a rotating part of a system. It consists of a set of brushes that make contact with a rotating ring, providing a continuous electrical connection.
By using a slip ring, the electrical power generated by the stationary engine can be transmitted to the rotating propeller blades without the need for physical wires that can get twisted or damaged due to the rotation. This allows the propeller to be powered by the electrical system of the aircraft, enabling efficient anti-icing/de-icing functionality.
