Abstract
A wing-fuselage truss joint assembly for an aircraft includes joining members secured to the aircraft's wing and fuselage structures. The joining members each include forward and aft wing joints and forward and aft fuselage joints connected by an upright member. The forward joining members are pivotally connected using interconnecting members and the aft joining members are connected using aft truss members. The forward-right and aft-right joining members and the forward-left and aft-left joining members are connected by truss link members and diagonal truss link members. The wing-fuselage truss joint assembly is configured to reduce forces experienced by the wing from being transferred to the aircraft fuselage.
Claims20
A wing-fuselage truss joint assembly for an aircraft comprising:
- a forward-left joining member, an aft-left joining member, a forward-right joining member, and an aft-right joining member configured to join a wing to a fuselage, wherein the joining members comprises:
- a wing truss joint mechanically coupled to a spar of the wing;
- a fuselage truss joint mechanically coupled to a bulkhead of the fuselage;
- and
- an upright member pivotally coupled to the wing truss joint at a first end and pivotally coupled to the fuselage truss joint at a second end wherein the second end is received in between opposing sidewalls of a channeled aperture formed into the fuselage truss joint;
- an interconnecting joint mechanically coupled to a forward bulkhead between the forward-left joining member and the forward-right joining member;
- at least one interconnecting member pivotally coupled to the interconnecting joint and pivotally coupled to a forward wing truss joint;
- a left diagonal linking member pivotally coupled directly to an aft-left fuselage truss joint at a left pivotal connection and pivotally coupled to a forward-left wing truss joint, wherein the left pivotal connection is formed into the aft-left fuselage truss joint;
- and
- a right diagonal linking member pivotally coupled directly to an aft-right fuselage truss joint at a right pivotal connection and pivotally coupled to a forward-right wing truss joint, wherein the right pivotal connection is formed into the aft-right fuselage truss joint.
