Abstract:
A front landing gear system for an aircraft including a swing arm rotatively coupled to a wheel, a forward link arm rotatively coupled to the swing arm, a oleopneumatic cylinder rotatively coupled to the swing arm, second extension arm and a bulkhead, a plate rotatively coupled to the bulkhead, an actuation device rotatively coupled to the bulkhead and to the plate, where retraction of the linear actuation device causes the plate and extension arms to move upward towards the bulkhead.
Abstract:
According to the invention, the upper end of the inclined front strut (9i) of the landing gear is connected to the structure (2A) of the fuselage by connecting means (13, 17).
Abstract:
Disclosed is an arrangement in which the main landing gear assemblies of a large commercial airplane are each joined to the airplane at four attachement points. Two of the attachment points connect the landing gear side brace (12) and drag brace (14) to the airplane. The two remaining attachment points are aft (36) and forward trunnions (46) that are mounted to the airplane wing. The aft trunnion (36) pivotally connects one side of the landing gear shock strut (10) to the airplane and carries both vertical and torsional loading. The forward trunnion (46) is pivotally connected to the other side of the shock strut (10) by a trunnion link (44). An actuator (56) is coupled between the shock strut (10) and the trunnion link (44).
Abstract:
In a commercial aircraft with a main deck (2) and a lower deck (5, 6), at least one passenger cabin (16, 16’) is also provided on the lower deck. The fuselage diameter lies on the order of a wide-body aircraft, and an energy-absorbing deformation structure (22, 23, 24) is arranged underneath the lower deck cabin. The invention proposes to arrange the wings (7) on the aircraft fuselage in accordance with the shoulder wing configuration, and to arrange the landing gear (10) outside on the fuselage such that the landing gear bays are spaced apart from one another by a certain distance that is defined by the positioning of the bottom longeron spars (9). This may provide that the lower deck volume situated underneath the main deck can be optimally utilized for payloads. The lower deck areas may also be interconnected in such a way that a significant useful width of the passage between the landing gear bays is achieved.
Abstract:
A supersonic cruise configuration aircraft (100) comprises a fuselage (142) extending on a longitudinal axis from a forward nose (110) to an aft tail (114), and a wing (104) coupled at an inboard section to the fuselage (142) and extending to an outboard tip, and having a leading edge and a trailing edge. The aircraft (100) further comprises a landing gear (146) that is coupled to the wing (104) and capable of stowing into the wing (104) and fuselage (142) on retraction. The landing gear (146) has a landing gear strut. The wing (104) is gulled with a dihedral (152) at an angle that is increased inboard and aligns with the retracted landing gear (146). The wing (104) has a minimum thickness sufficient to enclose the landing gear (146).

Abstract:
A fuselage for an airplane including a frame comprising an upper truss and a lower truss extending from a front end of the fuselage towards the rear end of the fuselage, wherein the lower truss comprises one or more forward box beams, a plurality of support rings attached to the upper truss and lower truss, a front bulkhead connected to a first end of the upper truss and lower truss, a main bulkhead connected to the upper truss and lower truss, a pressure vessel adapted to fit within the frame between the front bulkhead and main bulkhead, and a skin adapted to fit over the frame.
Abstract:
A main landing gear system for an aircraft including a truss element including a front portion joined to a rear portion, a first support unit and second support unit affixed to the truss at the junction of the first portion and the second portion on opposing sides of the truss, a first actuator and a second actuator rotatively affixed to respective first support unit and second support unit and to a respective first wheel and second wheel, a first trailing link and second trailing link each coupled to the respective first wheel and second wheel.
Abstract:
A landing gear (10) for an aircraft having a main fitting (12) arranged to be coupled to the aircraft and arranged to move between a stowed condition and a deployed condition and a trailing arm (14) movably coupled to the main fitting (12). A torsion spring (24) is coupled to the trailing arm (14) such that the movement of the trailing arm (14) causes torsion loading of the torsion spring (24). A stay assembly (24,26) is provided which comprises the torsion spring (24), the stay assembly (24,26) having a first condition in which it is arranged to react axial loading thereof so as to maintain the main fitting (12) in the deployed condition and a second condition in which it is arranged to permit the main fitting (12) to move between the stowed condition and the deployed condition.
