Title
(EN) NACELLE CONSTRUCTION FOR A WIND TURBINE
(FR) STRUCTURE DE NACELLE POUR UNE ÉOLIENNE
Abstract
(EN)
A heli-hoist pad (18) that is incorporated into a wind turbine nacelle (12) in a manner that is optimized for helicopter approach and positioning of the heli-hoist pad (18), such as by being located within a recess (20) in an upper surface (28) of the wind turbine nacelle (12). Heat exchangers (50) may also be positioned within the free flow of wind outside of a nacelle (12) in manners that provide for serviceability while also allowing for optimal positioning of a heli-hoist pad (18).
(FR)
L'invention concerne une rampe d'hélitreuillage incorporée dans une nacelle d'éolienne de manière à être optimisée pour l'approche d'un hélicoptère et pour le positionnement de la rampe d'hélitreuillage en étant située dans un évidement dans une surface supérieure de la nacelle d'éolienne. Des échangeurs de chaleur peuvent également être positionnés à l'intérieur des flux de vent libres à l'extérieur d'une nacelle de manière à être fonctionnels tout en permettant également le positionnement optimal d'une rampe d'hélitreuillage.
