Abstract: A wind turbine has a nacelle which houses operative components such as a transformer or converter which in use generate unwanted heat, the nacelle including an external nacelle cover (20) to form the outer nacelle enclosure, and provided with a panel (24) which overlies a bottom cover (22) region forming therewith a conduit for directing external air to one or more of the heat generating operative components for cooling purposes.

Abstract: A nacelle bottom cover part (32) for the underside of a wind turbine nacelle is formed with a number of shallow receptacle regions for containing liquid leaked or spilled from turbine components. Overflow channels (88,90,92) may be provided between the receptacle regions so that leaked liquid can flow between receptacle regions.

Abstract: A nacelle for a wind turbine, the nacelle comprising a roof panel forming an opening into an internal space; a cooling arrangement extending upwards from the roof panel; and a closure movable between an open position revealing the opening and a closed position closing the opening. To enable easy parking of the closure and particularly to enable parking of the closure in a position where it does not occupy a large surface space on the roof panel, the nacelle further comprises a track configured to guide the closure between the open and the closed positions, the track being carried at least partly by the cooling arrangement.

Abstract: A device for a motorized aircraft includes at least one avionic component positioned in the aircraft, at least one engine interface positioned in the aircraft and at least one engine controller positioned in or near an engine of the aircraft. The at least one engine interface is designed to exchange data between the at least one avionic component and the at least one engine controller. The at least one engine interface is generic and able to communicate with engine controllers of various types that may be mounted on the aircraft. The at least one engine controller is specific to a particular engine.

Abstract: The invention relates to a device for motorized aircraft comprising at least one avionic component (300) positioned in the said aircraft, at least one engine interface (310) positioned in the said aircraft and at least one engine controller (315) positioned in or near an engine (320) of the said aircraft. According to the device of the invention, the said at least one engine interface (310) is designed to exchange data between the said at least one avionic component (300) and the said at least one engine controller (315). The said at least one engine interface (310) is generic and able to communicate with engine controllers (315) of various types that may be mounted on said aircraft. The said at least one engine controller is specific to a particular engine.
