ABSTRACT:
A gas turbine engine has a forward rotor, a row of fan blades radially extending from the rotor, and a core turbine engine located rearwardly of the fan blades and rotor and coupled to the rotor for rotatably driving the rotor. An outer annular nacelle surrounds the rotor, fan blades and core engine. An inner annular splitter fairing is disposed rearwardly of the fan blades, surrounds the core engine, and is spaced radially inwardly from the nacelle so as to define therebetween a bypass air flow duct located outwardly from the core engine and rearwardly of the fan blades for producing thrust upon rotation of the rotor and fan blades. A hybrid shape spinner nose is attached about the rotor and projects forwardly therefrom within the nacelle and forwardly of the fan blades. The hybrid shape spinner nose has a forward substantially conical section spaced forwardly of the fan blades, a rearward substantially conical section projecting forwardly of and merging rearwardly with the fan blades, and a transition connecting the forward and rearward sections such that the spinner nose is provided with a compound, substantially conical configuration in which the slope of the forward substantially conical section is greater than the slope of an imaginary conical surface connecting a front end of the spinner nose and a leading edge of the annular splitter fairing, whereas the slope of the rearward substantially conical section is less than the slope of such imaginary conical surface.
