Abstract: Power generating apparatus (10) including a cable (12) which rotatably mounts a plurality of power units (14). The power units (14) include wind power turbines (46) for producing power from the wind as the power units (14) fly in the sky whilst connected to the cable (12).

Abstract: A bypass turbofan engine comprises a first propulsion system and a second propulsion system. The first propulsion system comprises a first fan rotor, a core engine, a first low pressure turbine and a first fan shaft drivingly connecting the first turbine and the first fan rotor. The second propulsion system comprises a second fan shaft drivingly connecting to a second fan rotor and the first propulsion system and arranged so that the first and second shafts are not coaxial with one another.

Abstract: Within a power generating arrangement 1 it is typically necessary to provide a coupling with an electrical power distribution cable 5. Previously this was sometimes achieved through use of brush gear and slip rings but such arrangements are subject to regular replacement for wear, maintenance and also there is a requirement to control humidity about the brush gear coupling. Alternatively, a system allowing an amount of rotation, limited by cable wind up was used. By providing a transformer in which windings 15, 16; 36, 37 are physically separated by an air gap 14, 39, but still induce voltage from variation in the magnetic flux, it is possible to create a power generating transfer transformer which can be rotated while driving electrical current for an external load.

Abstract: An engine (110, 210) for moving a conveyance (132) through a fluid includes first and second pressure creating means (13, 14) for pressurising an engine airflow, and intercooling means (116, 290, 292) for cooling the engine airflow between the first and second pressure creating means (13, 14). The intercooling means (116, 290, 292) includes a heat exchanger (116) which is arranged to be cooled by a flow of the fluid generated by the relative movement of the conveyance (132) through the fluid.
