AIRCRAFT AND LANDING GEAR PROVIDED WITH AT LEAST ONE PAIR OF SHOCK ABSORBERS, AND A METHOD PERFORMED BY SAID LANDING GEAR

摘要

Landing gear for an aircraft, the landing gear having at least one pair of shock absorbers comprising a first shock absorber and a second shock absorber, each shock absorber comprising a cylinder defining an inside space and a rod carrying a piston, the inside space being subdivided at least into a “primary” chamber and into a “secondary” chamber, the shock absorber including at least one throttling orifice putting the secondary chamber into fluid flow communication with the primary chamber. The primary chamber of the first shock absorber is connected to the secondary chamber of the second shock absorber of the pair by a first pipe, and the secondary chamber of the first shock absorber of the pair is connected to the primary chamber of the second shock absorber of the pair by a second pipe.

1. Landing gear for an aircraft, the landing gear being provided with a longitudinal bearing first skid and a longitudinal bearing second skid together with a cross-member referred to as a “front” cross-member and a cross-member referred to as a “rear” cross-member, each cross-member extending transversely and suitable for connecting the first skid and the second skid to a fuselage of the aircraft, each cross-member having a first branch connected to the first skid and a second branch connected to the second skid, the first skid and the second skid being situated transversely on either side of a vertical anteroposterior plane of symmetry, the landing gear including at least one pair of shock absorbers comprising a first shock absorber and a second shock absorber arranged transversely on either side of the anteroposterior plane, each shock absorber being attached to a cross-member, each shock absorber comprising a cylinder defining an inside space and a rod carrying a piston, the inside space being subdivided at least into a chamber referred to as “primary” chamber possessing an inside volume that decreases when the rod is pushed into the cylinder and into a chamber referred to as “secondary” chamber, each of the chambers being filled with a fluid, each shock absorber including at least one throttling orifice putting the secondary chamber and the primary chamber into fluid flow communication, each piston defining at least part of a chamber in order to move the fluid,
wherein the primary chamber of the first shock absorber of a pair is connected to the secondary chamber of the second shock absorber of the pair via a pipe referred to as a “first” pipe, and the secondary chamber of the first shock absorber of the pair is connected to the primary chamber of the second shock absorber of the pair by a pipe referred to as the “second” pipe.
