Abstract

The invention relates to a landing gear ( 1 ) of an aircraft ( 5 ), comprising: a strut assembly ( 10 ) including a first end ( 10 a ) designed to be mounted on the aircraft ( 5 ) and a second end ( 10 b ) opposite the first end ( 10 a ); a rod ( 14 ) slidably mounted on the second end ( 10 b ) of the strut assembly ( 10 ), said rod ( 14 ) being translationally movable in relation to the strut assembly ( 10 ); and at least one obstacle detector ( 2 ) secured to the landing gear ( 1 ), the landing gear ( 1 ) being characterized in that the obstacle detector ( 2 ) is secured in a zone adjacent to the second end ( 10 b ) of the strut assembly ( 10 ).

First claim

The invention claimed is:

1. A landing gear for an aircraft comprising:
a casing, having a main direction extending along a longitudinal axis, said casing comprising a first end configured to be mounted on the aircraft, and a second end opposite to the first end,
a rod, slidably mounted on the second end of the casing, said rod being movable in translation with respect to the casing along the longitudinal axis,
at least one obstacle detector attached to the landing gear, wherein the obstacle detector is attached in an area adjacent to the second end of the casing.

2. The landing gear according to claim 1 , wherein the obstacle detector is attached to the casing.

3. The landing gear according to claim 1 , further comprising a brace-strut, said brace-strut comprising a first end configured to be mounted on the aircraft and a second end configured to be connected to the casing in an area adjacent to the second end of said casing, and wherein the obstacle detector is attached in an area adjacent to the brace-strut.

4. The landing gear according to claim 3 , wherein the detector is attached to the casing, between the second end of the brace-strut and the first end of the casing.

5. The landing gear according to claim 1 , wherein the obstacle detector is attached so as to be oriented toward a rear area of the landing gear, said rear area being intended to be oriented toward a rear area of an aircraft.

6. The landing gear according to claim 1 , wherein the obstacle detector is attached in a lateral area of the landing gear, preferably in the internal portion of the landing gear.

7. The landing gear according to claim 1 , comprising at least two obstacle detectors.

8. The landing gear according to claim 7 , wherein the obstacle detectors are attached together so as to form a single part.

9. The landing gear according to claim 1 , wherein the obstacle detector comprises at least one, preferably at least two obstacle detectors selected from the following group: infrared proximity detector, microwave proximity detector, ultrasonic proximity detector, one or more infrared or visible cameras, an ultrasonic range finder, a radar range finder or a laser range finder.

10. The landing gear according to claim 1 , further comprising an actuator configured to rotate the obstacle detector around the longitudinal axis of the casing.

11. The landing gear according to claim 1 , further comprising a wiring harness configured to control transmission of power within the landing gear, said wiring harness being attached to the landing gear using elastically deformable attachment rings, and wherein the obstacle detector comprises cables attached to the landing gear using the attachment rings of the wiring harness.

12. The landing gear according to claim 1 , wherein the obstacle detector comprises a detection field having an aperture and a depth configured to cover a lower area of the aircraft and a rear area of the aircraft.

13. The landing gear according to claim 12 , wherein the aperture of the detection field has a horizontal viewing angle comprised between 0° and 180°, and the depth of the detection field is comprised between approximately 0 meter and 250 meters.

14. The landing gear according to claim 1 , comprising a main landing gear or a nose landing gear of the aircraft.

15. The landing gear according to claim 1 , wherein it is retractable.

16. An aircraft, comprising a landing gear according to claim 1 .
