An actuator includes a body and at least a first offset connection port that is connected to the body by a first duct projecting from the body. The first connection port is mechanically connected to the body at least by first and second struts. The first strut and the second strut extend from the first connection port, respectively, to a first segment of the body and to a second segment of the body that is axially spaced apart from the first segment. An undercarriage includes such an actuator as its locking or unlocking actuator.

A landing gear includes structural parts arranged to connect a wheel to a structure of an aircraft, each structural part including two or more interfaces for connection to one or more other of the structural parts or to the structure of the aircraft and two or more webs which extend so as to face one another while delimiting between them a free space and which connect the two interfaces in order to transmit the forces from one to the other.

A method of additive manufacturing including defining contiguous portions over a ceiling of a cavity of a part, including a central portion defined entirely by first edges, and peripheral portions defined by second edges and by a portion of a frontier of the ceiling. Defining a capital by facets that bear against the first edges and that converge towards an apex, and defining a slender support that extends from the capital to a cavity floor while being centered on the apex. For each peripheral portion, defining a capital by facets that bear against the second edges and that converge towards a terminal edge extending in a plane that is normal to a wall of the cavity, and defining a rib support that extends in the normal plane between the terminal edge and a wall of the cavity. Manufacturing the part including the cavity while making the supports and capitals.

Drive equipment for rotating by friction an aircraft wheel equipped with a drive track and mounted to turn about an axis (X) on an axle of an aircraft undercarriage. The equipment comprise a base (), a slide () mounted on the base on a sliding axis extending in a radial direction (R, R), a support () pivotable on the slide on an axis parallel to the rotation axis of the wheel; two rollers () rotatable on rotation axes parallel to the pivot axis; a central shaft () mounted for rotation on the support and being in engagement with the two rollers to provide their rotation; and an actuator (A,B,) for moving the slide and the support between a disengagement position with the rollers distant from the wheel drive track and an engagement position with the rollers are held in contact with the drive track of the wheel.
