Debris deflector for a jet engine
View Patent ↗A debris deflector for a jet engine. The debris deflector includes a housing having a base and a nose, wherein the housing tapers radially inwardly from the base towards the nose, such that the nose can deflect debris away from the housing. The housing includes a flexible shroud that extends between the base and the nose, such that the housing can selectively move between a collapsed position and an extended position, such that a linear distance between the nose and the base is less when in the collapsed position. A fastener is disposed on the base to removably secure the housing to a jet engine cowling. The debris deflector is useful for deflecting debris, such as wildlife or small aircraft, away from the jet engine during flight.
1. A debris deflector for a jet engine, comprising:
a housing having a base centered about a centerline axis and a nose;
wherein the housing tapers radially inwardly relative to the centerline axis from the base towards the nose when the housing is in an extended position, such that the nose is configured to deflect debris away from the housing;
wherein the housing is a flexible shroud extending from the base to the nose;
wherein the housing is configured to selectively move between a collapsed position and the extended position;
wherein a linear distance along the centerline axis from the base to the nose is greater when the housing is in the extended position than when the housing is in the collapsed position;
a fastener disposed on the base, wherein the fastener is configured to removably secure the housing to a jet engine cowling.
2. The debris deflector of claim 1 , further comprising a plurality of concentric ribs distributed over a length of the housing, wherein the plurality of concentric ribs is configured to provide support to the flexible shroud.
3. The debris deflector of claim 2 , wherein the plurality of concentric ribs defines discrete sections of the flexible shroud, wherein each section extends between two adjacent ribs of the plurality of concentric ribs.
4. The debris deflector of claim 2 , wherein a first rib of the plurality of concentric ribs is directly affixed to a forward edge of the base.
5. The debris deflector of claim 2 , wherein a last rib of the plurality of concentric ribs is directly affixed to a rear edge of the nose.
6. The debris deflector of claim 2 , wherein each of the plurality of concentric ribs comprises a diameter and the diameters decrease from the base towards the nose.
7. The debris deflector of claim 2 , wherein the plurality of concentric ribs are configured to be coplanar when the housing is in the collapsed position.
8. The debris deflector of claim 1 , wherein the shroud comprises a mesh.
9. The debris deflector of claim 1 , wherein the fastener comprises a bracket configured to engage an interior of the jet engine cowling.
10. The debris deflector of claim 9 , wherein the bracket comprises a first section extending perpendicularly away from a second section, such that the first section is removably securable to the interior of the jet engine cowling.
11. The debris deflector of claim 10 , wherein the second section comprises an arcuate shape curving radially inwardly toward the centerline axis from the base.
12. The debris deflector of claim 1 , wherein the nose tapers to a point at a distal end thereof.
13. The debris deflector of claim 12 , wherein the nose comprises a first portion affixed to a second portion, wherein the first portion tapers radially inwardly relative to the centerline axis at a rate greater than that of the second portion.
