Abstract
The invention is directed a trapezoidal panel pin joint for allowing deflection of an aircraft between a fuselage section and a wing section, wherein the pin joint comprises a vertical pin portion, a lug portion, and a clevis portion; wherein at least one vertical flexible tee member is positioned below the pin joint; and wherein the pin joint is coupled to at least two horizontal flexible tee members, such that the pin joint and vertical and horizontal flexible tee members, in combination, release two rotational degrees of freedom.

A trapezoidal panel pin joint for allowing deflection of an aircraft between a fuselage section and a wing section, the pin joint comprising a vertical pin portion, a lug portion, and a clevis portion, and the pin joint is positioned at a wing rear spar of the aircraft;
- and at least one vertical flexible tee member is positioned below the pin joint;
- and the pin joint is coupled to at least two horizontal flexible tee members, such that the pin joint and vertical flexible tee member allow for vertical rotation at the wing rear spar, and such that the horizontal flexible tee members allow for horizontal rotation at a wing/fuselage joint.
A trapezoidal panel pin joint for allowing deflection between a fuselage section and a wing section of an aircraft, the pin joint comprising a vertical pin portion, a lug portion, and a clevis portion, and the pin joint is positioned at a wing rear spar of the aircraft;
- and at least one vertical flexible tee member having a vertical flexible rabbet is positioned below the pin joint, and along with the pin joint, connects a trapezoidal panel in the fuselage section to the wing rear spar;
- and the pin joint is coupled to at least two horizontal flexible tee members each having a horizontal flexible rabbet, such that the pin joint and the vertical flexible tee member allow for vertical rotation at the wing rear spar, and such that the horizontal flexible tee members allow for horizontal rotation at a wing/fuselage joint.
