Abstract
A nose cone may have a spinner including a main portion and an axially extending stepped portion. The nose cone may also have an annular aft support ring radially secured to the axially extending stepped portion. The nose cone may further include a fairing, which may be secured to the stepped portion.
Claims16
A nose cone for a gas turbine engine, the nose cone comprising:
- a substantially conical spinner, the spinner including a main portion and an axially extending stepped portion;
- an annular aft support ring, the aft support ring radially secured to the axially extending stepped portion;
- and
- a fairing, the fairing secured to the stepped portion, wherein the axially extending stepped portion further includes a receiving joint for receiving the fairing and an interference fitting lip for receiving the annular aft support ring and wherein the annular aft support ring further includes an interference fitting flange having an outer diameter that is slightly greater than an inner diameter of the interference fitting lip so that the interference fitting lip is force-fitted over the interference fitting flange creating a frictional bond, which maintains concentricity between the spinner and the aft support ring.

A gas turbine engine, comprising:
- a fan hub;
- a substantially conical spinner, the spinner including a main portion and an axially extending stepped portion;
- an annular aft support ring, the aft support ring radially secured to the axially extending stepped portion, the aft support ring mounted to the fan hub;
- and
- a fairing, the fairing secured to the stepped portion, wherein the axially extending stepped portion further includes a receiving joint for receiving the fairing and an interference fitting lip for receiving the annular aft support ring, and wherein the annular aft support ring further includes an interference fitting flange having an outer diameter that is slightly greater than an inner diameter of the interference fitting lip so that the interference fitting lip is force-fitted over the interference fitting flange creating a frictional bond, which maintains concentricity between the spinner and the aft support ring.
