Abstract

A rotor includes a base member including a first side, a second side opposite the first side, and a central opening passing through the first side and the second side. The second side includes an outer circumferential edge having a first dimension and the central opening having an inner circumferential edge having a second dimension. A plurality of blades extend outwardly from the first side. The plurality of blades extend about the central opening. A fuse element is formed in the second side and extends along one of a radial direction and a circumferential direction. The fuse element has a length that is less than the first dimension.

First claim

What is claimed is:

1 . A rotor comprising:
a base member including a first side, a second side opposite the first side, and a central opening passing through the first side and the second side, the second side including an outer circumferential edge defined by a first dimension of the base member and the central opening having an inner circumferential edge defined by a second dimension; a plurality of blades extending outwardly from the first side, the plurality of blades extending about the central opening; and a first fuse element formed in the second side and extending along one of a radial direction and a circumferential direction, the first fuse element having a length that is less than the first dimension; wherein the first fuse element includes a first end positioned at the inner circumferential edge, a second end positioned at the outer circumferential edge, and an intermediate portion.

2 . The rotor according to claim 1 , wherein the intermediate portion is linear.

3 . The rotor according to claim 2 , wherein the intermediate portion extends at an angle relative to a radius of the second side.

4 . The rotor according to claim 1 , further comprising a second fuse element extending along a radius of the second side.

5 . The rotor according to claim 4 , wherein the first fuse element is spaced from the second fuse element.

6 . The rotor according to claim 5 , wherein the first fuse element and the second fuse element are co-linear.

7 . The rotor according to claim 1 , wherein the first fuse element extends along a radius of the second side, the rotor further comprising a second fuse element extending along a circumference of the second side.

8 . The rotor according to claim 1 , the first fuse element forming a built-in failure mechanism including a uniform cross-section.

9 . An aircraft comprising:
a fuselage defining a cockpit and a passenger cabin; an air conditioning unit configured to direct conditioned air into one of the cockpit and the passenger cabin, the air conditioning unit including a rotor as recited reciting in claim 1 .

10 . The aircraft according to claim 9 , wherein the intermediate portion is curvilinear, the first fuse element extending along a circumference of the second side between the inner circumferential edge and the outer circumferential edge.
