Abstract

An anti-lofting deflector for landing gear having two wheels on an axle. The deflector comprises a stationary support ( 5 ) for being fastened in service to a portion of the landing gear that carries the axle in order to extend between the wheels and present a distal end behind the wheels. It also has a first flap ( 2 ) hinged to the support via its distal end about a first hinge axis (X 1 ) substantially parallel to the axle and a second flap ( 3 ) hinged to the first flap about a second hinge axis (X 2 ) substantially parallel to the first hinge axis. Finally, there is a a return member ( 11 ) arranged so as to urge the second flap against an abutment of the first flap that prevents the second flap from becoming aligned with the first flap, and to urge the first flap against an abutment of the stationary support that prevents the first flap from folding against the support.

First claim

The invention claimed is:

1. An anti-lofting deflector for landing gear having two wheels on an axle, the deflector comprising:
a stationary support ( 5 ) for being fastened in service to a portion of the landing gear that carries the axle in order to extend between the wheels and present a distal end behind the wheels;
a first flap ( 2 ) hinged to the support via its distal end about a first hinge axis (X 1 ) substantially parallel to the axle;
a second flap ( 3 ) hinged to the first flap about a second hinge axis (X 2 ) substantially parallel to the first hinge axis; and
a return member ( 11 ) arranged so as to urge the second flap against an abutment of the first flap that prevents the second flap from becoming aligned with the first flap, and to urge the first flap against an abutment of the stationary support that prevents the first flap from folding against the support.

2. An aircraft landing gear comprising an anti-lofting deflector as defined in claim 1 .

3. The aircraft landing gear as recited in claim 2 , wherein said landing gear is nose landing gear.

4. An anti-lofting deflector for landing gear having two wheels on an axle, the deflector comprising:
a stationary support ( 5 ) for being fastened in service to a portion of the landing gear that carries the axle in order to extend between the wheels and present a distal end behind the wheels;
a first flap ( 2 ) hinged to the support via its distal end about a first hinge axis (X 1 ) substantially parallel to the axle;
a second flap ( 3 ) hinged to the first flap about a second hinge axis (X 2 ) substantially parallel to the first hinge axis; and
a return member ( 11 ) arranged so as to urge the second flap against an abutment of the first flap that prevents the second flap from becoming aligned with the first flap, and to urge the first flap against an abutment of the stationary support that prevents the first flap from folding against the support,
wherein the return member comprises a spring ( 11 ) coupled between the second flap and a stationary point of the support or of the landing gear, the spring extending along a line of action (L) that passes between the hinge axes (X 1 , X 2 ).

5. An aircraft landing gear comprising an anti-lofting deflector as defined in claim 4 .

6. The aircraft landing gear as recited in claim 5 , wherein said landing gear is nose landing gear.
