Abstract

Aircraft landing gear assemblies and aircraft are provided. A landing gear assembly includes a main post and a light element cluster. The main post has a non-rotating portion and a rotatable steering portion. The light element cluster is associated with the non-rotating portion and includes at least two independently illuminating sections.

First claim

What is claimed is:

1. A landing gear assembly for an aircraft, the landing gear assembly comprising:
a main post having a non-rotating portion and a rotatable steering portion;
a lamp fairing rotationally fixed to the non-rotating portion;
a tiller rotationally coupled with the rotatable steering portion of the main post; and
a light element cluster associated with the non-rotating portion, attached to the lamp fairing and including at least two independently illuminating sections, wherein the at least two independently illuminating sections include a first starboard section configured to face a starboard side of the aircraft and a first port section configured to face a port side of the aircraft, and
wherein the first starboard section is configured to illuminate in response to the tiller rotating to point the rotatable steering portion to the starboard side, and wherein the first port section is configured to illuminate in response to the tiller rotating to point the rotatable steering portion to the port side.

2. The landing gear assembly of claim 1 , wherein the lamp fairing is configured to minimize aerodynamic noise and drag.

3. The landing gear assembly of claim 1 , further comprising an encapsulating material disposed on the light element cluster across at least two independently illuminating sections to form an outer surface of the lamp fairing.

4. The landing gear assembly of claim 1 , further comprising a controller operatively coupled with the light element cluster and configured to illuminate the first starboard section and the first port section in response to a steering angle of the tiller.

5. The landing gear assembly of claim 1 , wherein the first starboard section of the light element cluster is oriented to illuminate to the starboard side at least up to a starboard maximum steering angle of the landing gear assembly, and wherein the first port section of the light element cluster is oriented to illuminate to the port side at least up to a port maximum steering angle of the landing gear assembly.

6. The landing gear assembly of claim 1 , wherein the light element cluster further comprises a second starboard section and a second port section, and wherein the second starboard section is disposed between the first starboard section and the second port section, and the second port section is disposed between the second starboard section and the first port section.

7. The landing gear assembly of claim 1 , wherein each of the at least two independently illuminating sections includes an array of light emitting diodes (LED).

8. The landing gear assembly of claim 1 , wherein the light element cluster is disposed on a substantially cylindrical portion of the lamp fairing.

9. The landing gear assembly of claim 1 , wherein the lamp fairing defines a first concave portion and a second concave portion, wherein the first concave portion and the second concave portion each have a continuously decreasing diameter from the substantially cylindrical portion to the non-rotating portion of the main post.

10. An aircraft, comprising:
a fuselage defining a landing gear bay;
a landing gear assembly at least partially disposed in the landing gear bay and comprising:
a tiller, and
a main post having a non-rotating portion and a rotatable steering portion, wherein the rotatable steering portion is coupled with the tiller and is configured to rotate with the tiller; and

a light element cluster fixed for common rotation with the fuselage and configured to illuminate based on a steering angle of the tiller.

11. The aircraft of claim 10 , wherein the landing gear assembly further includes a lamp fairing rotationally fixed to the non-rotating portion and configured to minimize aerodynamic noise and drag, and wherein the light element cluster is secured to the lamp fairing and includes two independently illuminating sections.

12. The aircraft of claim 11 , wherein the light element cluster is disposed on a substantially cylindrical portion of the lamp fairing.

13. The aircraft of claim 12 , wherein the lamp fairing defines a first concave portion and a second concave portion, wherein the first concave portion and the second concave portion each have a continuously decreasing diameter from the substantially cylindrical portion to the non-rotating portion of the main post.

14. The aircraft of claim 10 , wherein the light element cluster includes at least two independently illuminating sections that include a first starboard section configured to face a starboard side of the aircraft and a first port section configured to face a port side of the aircraft.

15. The aircraft of claim 14 , wherein the first starboard section is configured to illuminate in response to the tiller rotating to point the rotatable steering portion to the starboard side, and wherein the first port section is configured to illuminate in response to the tiller rotating to point the rotatable steering portion to the port side.

16. The aircraft of claim 14 , further comprising a controller operatively coupled with the light element cluster and configured to illuminate the first starboard section and the first port section in response to a steering angle of the tiller.
