4. Aircraft according to claim 3 , characterized in that the articulation means ( 38 ) comprise a support ( 42 ) adapted to receive at least one wheel axle ( 34 ) and connected to the gear leg ( 32 ) by a pivot connection with an axis L substantially parallel to the axis J of the gear leg ( 32 ).
5. Aircraft according to claim 4 , characterized in that only one of the wheels ( 36 ) can be inclined at an angle φ relative to the lifting plane P.
6. Aircraft according to claim 4 , characterized in that the two wheels ( 36 ) can be inclined in an opposite manner by an angle a relative to the lifting plane P.
7. Aircraft according to claim 4 , characterized in that the angle between the wheel ( 36 ) and the lifting plane P is an angle opening inwardly of the aircraft ( 20 ) when the landing gear ( 24 ) is raised.
8. Aircraft according to claim 3 , characterized in that only one of the wheels ( 36 ) can be inclined at an angle φ relative to the lifting plane P.
9. Aircraft according to claim 3 , characterized in that the two wheels ( 36 ) can be inclined in an opposite manner by an angle a relative to the lifting plane P.
10. Aircraft according to claim 3 , characterized in that the angle between the wheel ( 36 ) and the lifting plane P is an angle opening inwardly of the aircraft ( 20 ) when the landing gear ( 24 ) is raised.
11. Aircraft according to claim 1 , characterized in that only one of the wheels ( 36 ) can be inclined at an angle φ relative to the lifting plane P.
12. Aircraft according to claim 11 , characterized in that the angle between the wheel ( 36 ) and the lifting plane P is an angle opening inwardly of the aircraft ( 20 ) when the landing gear ( 24 ) is raised.
13. Aircraft according to claim 1 , characterized in that the two wheels ( 36 ) can be inclined in an opposite manner by an angle a relative to the lifting plane P.
14. Aircraft according to claim 1 , characterized in that the angle between the wheel ( 36 ) and the lifting plane P is an angle opening inwardly of the aircraft ( 20 ) when the landing gear ( 24 ) is raised.
15. An aircraft comprising:
a gear compartment including an upper panel ( 50 ) serving as a floor with a hollow shape; and
a raisable forward landing gear ( 24 ) adapted to be disposed in the gear compartment,
the landing gear comprising a gear leg ( 32 ) connected to the aircraft structure ( 20 ), a pair of wheels ( 36 ) disposed on opposite sides of the gear leg ( 32 ), and articulation means ( 38 ) to incline the pair of wheels ( 36 ) relative to a lifting plane P of the landing gear ( 24 ), wherein,
at least one of the pair of wheels is enclosed by the hollow shape when the landing gear is in the raised position, and
only one of the pair of wheels ( 36 ) can be inclined at an angle φ relative to the lifting plane P.
16. An aircraft comprising:
at least one gear compartment in which is adapted to be disposed a raisable forward landing gear ( 24 ),
said landing gearing comprising at least one gear leg ( 32 ) connected to an aircraft structure ( 20 ) and supporting at least one pair of wheels ( 36 ),
said wheels ( 36 ) being disposed on opposite sides of the gear leg ( 32 ),
said landing gear ( 24 ) comprising articulation means ( 38 ) so as to incline at least one wheel ( 36 ) relative to the lifting plane P of the landing gear ( 24 ),
said articulation means ( 38 ) being connected by a connection permitting at least one rotation,
said gear compartment comprising an upper panel ( 50 ) serving as a floor and having at least one hollow shape F being angled with respect to the lifting plane P and enclosing at least one of wheels ( 36 ) when the landing gear is in raised position, the floor including protuberances corresponding to the at least one hollow shape F.
