A propulsion system for a propeller of an aircraft is described, wherein the propulsion system allows for transmission of electrical power such as for a deicing system for the propeller. The propulsion system comprises a rotatable shaft for transmission of mechanical power; aircraft end electrical connections at an aircraft end of the shaft for connection to first and second terminals of a source of electrical power; propeller end electrical connections at a propeller end of the shaft and being for connection to first and second terminals for supplying electrical power to electrical components on the propeller; and a mechanical coupling at the propeller end of the shaft for mounting the propeller to the shaft. The shaft comprises: an inner conductor extending along the length of the shaft; an outer conductor extending along the length of the shaft; and an electrical insulator extending along the shaft in between the inner and outer conductor.
