Abstract
A pinned lug joint comprising: a first part comprising two first lugs projecting from a bridge which extends between them; a second part pivotally coupled to the first part, the second part comprising a second lug positioned between the first lugs; and a sealing member, the sealing member being mounted to the first lugs and extending between them to seal an air gap between the second lug and the bridge at least when the second part is in a first position. The pinned lug joint may be used to attach a panel assembly to part of an aircraft.
Claims15
A pinned lug joint comprising:
- a first part comprising two first lugs projecting from a bridge which extends between them;
- a second part pivotally coupled to the first part, the second part comprising a second lug positioned between the first lugs;
- and a sealing member, the sealing member being mounted to the first lugs and extending between them to seal an air gap between the second lug and the bridge at least when the second part is in a first position.
A pinned lug joint comprising:
- a first lug pivotally coupled to a second lug;
- and a seal mounted on one of the lugs, the seal comprising a flange which extends between the first and second lugs to seal an air gap between them.
A panel assembly comprising:
- an aerodynamic surface pivotally coupled to part of an aircraft by a hinge fitting, the surface comprising a cut-out section to avoid clashing with the hinge fitting when the surface is pivoted to a first position;
- and a sealing member attached to the aerodynamic surface and positioned in the cut-out section to at least partially fill the cut-out section at least when the aerodynamic surface is pivoted to a second position.
A method of reducing drag on an aerodynamic surface, the aerodynamic surface being pivotally coupled to part of an aircraft by a hinge fitting, the surface comprising a cut-out section to avoid clashing with the hinge fitting when the surface is pivoted to a first position, the method comprising attaching a sealing member to the aerodynamic surface and positioning the sealing member in the cut-out section to at least partially fill the cut-out section at least when the aerodynamic surface is pivoted to a second position.
A method of reducing air flow through a pinned lug joint, the joint comprising a first part pivotally coupled to a second part, the second part comprising two second lugs projecting from a bridge which extends between them, and the first part comprising a first lug positioned between the lugs of the second part, the method comprising:
- sealing a first air gap between the first lug and the bridge of the second part at least when the first part is in a predetermined position;
- and/or sealing a second air gap between the first lug and one of the second lugs;
- and/or sealing a third air gap between the first lug and the other second lug.
