AIRCRAFT COMPRISING A MAIN LANDING GEAR COMPARTMENT WITH A BODY WHICH IS PRODUCED IN A SINGLE PIECE

An aircraft including a main landing gear compartment which comprises a rear transverse wall, and a base wall forming a sealed barrier between a first, pressurized area and a second, non-pressurized area. The main landing gear compartment includes a body, produced in a single piece from composite material, separating the first, pressurized area and the second, non-pressurized area. The body includes a first part corresponding to the base wall, as well as a second part corresponding to the rear transverse wall. At least two longitudinal beams made of composite material, are connected to the body. This single body makes it possible to eliminate a large number of parts, to simplify the assembly process, and to reduce the duration thereof.

AIRCRAFT LANDING GEAR ASSEMBLY

An aircraft landing gear assembly having a first landing gear element movably coupled relative to a second landing gear element to move between a first condition and a second condition. The aircraft landing gear assembly further comprises a fibre composite leaf spring formed from a plurality of composite layers and arranged between the first and second elements, the leaf spring being arranged to bend when the first element moves from the first condition to the second condition. The fibre composite leaf spring comprises a first region and a second region, wherein the number of composite layers in the first region is greater than the number of composite layers in the second region. The landing gear further comprises a mounting assembly arranged to engage the first region of the leaf spring to couple the leaf spring to the first landing gear element.

Airborne Vehicle With Multi-Airfoil Tail

An airborne vehicle having a body section; a main wing extending from the body section configured to generate aerodynamic lift, the main wing having one or more main wing control surfaces; and a tail assembly extending from the body section aft of the main wing. The tail assembly having a first tail member and a second tail member substantially parallel to each other. The first tail member having one or more control surfaces and the second tail member having one or more flap surfaces selectively deployable between a retracted position and an extended position. The flap surfaces being configured to increase a surface area and/or camber of the second tail member in the extended position.

SEMI-LEVERED SHRINK LANDING GEAR
20230070675 · 2023-03-09 ·

A landing gear for use on an aircraft, the landing gear including a shock strut and an anti-rotation linkage. The shock strut is positioned at least partially within and guided in movement by a guide member coupled to a frame of the aircraft. The shock strut including an outer cylinder that is shaped and sized to engage the guide member where the guide member guides sliding movement of the outer cylinder, and where the outer cylinder is configured so as to be driven in the sliding movement relative to the guide member, and an inner cylinder disposed at least partly within the outer cylinder. The anti-rotation linkage including a connector plate coupled to the outer cylinder of the shock strut, and an anti-rotation link assembly coupled to both the guide member and the connector plate, the anti-rotation link assembly being configured to maintain the shock strut in a fixed rotational orientation relative to the guide member.

LANDING GEAR BAY COMPRISING A BOTTOM WALL HAVING A VAULTED FORM, AND AIRCRAFT COMPRISING SAID LANDING GEAR BAY
20220315200 · 2022-10-06 ·

A landing gear bay including a bottom wall which includes longitudinal beams and at least one panel forming an airtight barrier between first and second zones disposed on either side of the panel. The panel has first and second longitudinal edges each linked to one of the longitudinal beams. The second zone is configured to sustain a pressure greater than that of the first zone. The panel has a profile that is substantially constant in the longitudinal direction and includes at least one central part offset toward the second zone with respect to its first and second longitudinal edges. This solution makes it possible to limit the vertical stresses applied to the longitudinal beams by virtue of the pressure difference between the first and second zones.

Aerodynamic noise reducing thin-skin landing gear structures and manufacturing techniques

A thin-skin support member is provided. The thin-skin support member may include a semi-circular edge and a flat edge that define a hollow cavity. A cylindrical cavity may be adjacent the hollow cavity and at least partially defined by the semi-circular edge. The cylindrical cavity may be configured to retain a strut assembly. A mounting interface may be coupled to the semi-circular edge and the flat edge. A torsion interface may be disposed adjacent the cylindrical cavity and configured to receive a torsion link. The thin-skin support member may be made using additive manufacturing and thus may have a grain structure grown in the direction of material being added.
