An aircraft comprises wiring 15 configured to carry electrical power and an electromagnetic shielding arrangement providing an enclosure around the wiring configured to block electromagnetic emissions. The shielding arrangement comprises a first 20 and a second 21 shield which can move relative to the first, and a gap 22 (fig.5) between overlapping portions of the shields. The gap is configured to allow air 30, 31 to flow into or out of the enclosure via a gap. The wiring may provide power for a propulsion motor 14 connected to the wing via a pylon 5 such that the first shield is connected to the pylon and second shield is connected to the engine structure. The wiring may be configured to generate electromagnetic emissions at a signal wavelength with greater than the dimension of the gap. The air flow may contact the wiring to provide cooling. The wiring may comprise first, second, and third wiring 32a, 32b, 32c (fig.6) configured to carry electrical power at first second and third phases respectively. Also disclosed is an aircraft propulsion system comprising a propulsion motor, wiring and an electromagnetic shielding arrangement as described.
