Abstract

A turbine engine cowl capable of covering a fan cone, the cowl including attachment components configured to engage with connection components of the cone in order to maintain the cowl and the cone secured to one another.

Claims (14)

1. A rotating turbine engine fan cone, comprising connection components configured to engage with attachment components of a cowl of a turbine engine adapted to cover said cone to keep said cone and said cowl secured to each other, the attachment components including teeth, the connection components comprising:

a plurality of notches arranged at a base of the cone, said notches being adapted to house the teeth of the cowl, and;

a plurality of grooves opening up in the notches, and adapted to house projecting parts projecting from the teeth.

2. The rotating turbine engine fan cone according to claim 1 , wherein the connection components include four of the notches.

3. The rotating turbine engine fan cone according to claim 1 , wherein a width of one of the notches is not the same as the width of the other notches.

4. The rotating turbine engine fan cone according to claim 1 , wherein the connection components comprise a crimped nut positioned at a tip of the cone.

5. An assembly comprising a rotating turbine engine fan cone according to claim 1 , and a cowl of a turbine engine adapted to cover said cone, said cowl comprising attachment components configured to engage with the connection components of the cone to keep said cowl and said cone secured to each other, said attachment components comprising:

a plurality of teeth arranged at a base of the cowl, said teeth being adapted to be engaged in the notches of the cone;

a plurality of projecting parts projecting from teeth, and adapted to slide in the grooves of the cone opening up in the notches.

6. The assembly according to claim 5 , wherein the cowl is provided with four teeth.

7. The assembly according to claim 5 , wherein a width of one tooth is not the same as the width of the other teeth.

8. The assembly according to claim 5 , wherein the attachment components comprise a screw configured to be screwed onto a crimped nut of the cone, said crimped nut being positioned at a tip of the cone.

9. The assembly according to claim 5 , wherein the cowl has an approximately uniform outer surface.

10. The assembly according to claim 5 , wherein an inner surface of the cowl is complementary to an outer surface of the cone.
