==PROPELLER SHAFT WITH REINFORCED FRONT FLANGE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17932756 titled 'PROPELLER SHAFT WITH REINFORCED FRONT FLANGE

==Simplified Explanation==

The propeller shaft assembly for an aircraft engine described in the patent application includes a shaft with an annular wall, a front flange, and a reinforcement web with perforations.

* The shaft has an annular wall that defines a cavity in a front end portion, with an outer surface and an inner surface.
* A front flange projects radially outwardly from the annular wall and includes a hub side surface for abutting with a propeller hub.
* A reinforcement web extends radially inwardly from the inner surface of the annular wall, with at least part of it aligned with the front flange.
* At least one perforation extends axially through the reinforcement web.

== Potential Applications ==
This technology could be applied in aircraft engines, specifically in propeller shaft assemblies for improved structural integrity and performance.

== Problems Solved ==
This innovation solves the problem of reinforcing the front end portion of a propeller shaft assembly to withstand the forces and stresses experienced during operation.

== Benefits ==

==Original Abstract Submitted==

A propeller shaft assembly for an aircraft engine includes a shaft having: an annular wall extending circumferentially about a shaft axis and circumscribing a hollowed interior defining a cavity in a front end portion of the shaft, the annular wall having an outer surface and an inner surface facing radially inwardly to the cavity; and a front flange projecting radially outwardly from the annular wall. The front flange includes a hub side surface defining an interface plane and adapted to abut with a propeller hub. The shaft also includes a reinforcement web defining an end wall of the cavity, the reinforcement web extending radially inwardly from the inner surface of the annular wall. At least part of the reinforcement web is radially aligned with the front flange. At least one perforation extends axially through the reinforcement web.
