Abstract
A nose cone and fan assembly are disclosed. The fan assembly comprises a fan rotor and a nose cone retention flange. The fan rotor at least partly defines a fan assembly air flow boundary surface. The nose cone retention flange extends from the fan rotor and comprises a retention flange air flow boundary surface adjacent the fan assembly air flow boundary surface and a nose cone mating surface. The nose cone comprises a nose cone flange having a rotor mating surface. The nose cone is affixed to the nose cone retention flange with the rotor mating surface overlaying the nose cone mating surface of the nose cone retention flange.
