Abstract

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).
