An attachment system for a fan inlet case and bearing housing comprising:
- the fan inlet case connected to the bearing housing;
- an attachment in operative communication with the bearing housing, the attachment being threaded onto threads formed into an outer radial surface of a forward end of the bearing housing;
- and
- a locking ring in operative communication with the bearing housing between the attachment and the fan inlet case, wherein the attachment secures the locking ring and fan inlet case to the bearing housing.
A gas turbine engine with an attachment system for a fan inlet case and a bearing housing comprising:
- the fan inlet case connected to the bearing housing, the bearing housing comprising an aft end opposite a forward end of the bearing housing;
- an attachment in operative communication with the bearing housing, the attachment being threaded onto threads formed into an outer radial surface of a forward end of the bearing housing;
- a locking ring in operative communication with the bearing housing between the attachment and the fan inlet case, wherein the attachment secures the locking ring and fan inlet case to the bearing housing;
- and
- a nose cone attached to the fan inlet case through a threaded connection with the locking ring.
A process of forming a gas turbine engine with an attachment system for a fan inlet case and a bearing housing comprising:
- connecting the fan inlet case to the bearing housing, the bearing housing comprising an aft end opposite a forward end of the bearing housing;
- coupling an attachment in operative communication with the bearing housing, the attachment being threaded onto threads formed into an outer radial surface of a forward end of the bearing housing;
- coupling a locking ring in operative communication with the bearing housing between the attachment and the fan inlet case;
- securing the attachment to the locking ring and securing the fan inlet case to the bearing housing;
- and
- attaching a nose cone to the fan inlet case through a threaded connection with the locking ring.
