Claims12
A manufacturing method of a control surface of an aircraft, the control surface comprising:
- an upper skin,
- a lower skin,
- ribs joining the upper skin and the lower skin and located along a chordwise direction of the control surface,
- wherein the manufacturing method comprises the steps of:
- providing a single composite preform comprising the upper skin, the lower skin and the ribs, and
- curing said single composite preform such that an integrated box comprising the upper skin, the lower skin and the ribs is formed,
- wherein after the curing step of the integrated box, a curing tool located between the upper skin and the lower skin is extracted from the integrated box in a chordwise direction towards a front edge of the control surface,
- wherein the ribs are manufactured with their chordwise length shorter than the upper and lower skins chordwise length, and
- wherein the curing tool comprises a first part in contact with the upper skin and the lower skin and a second part having a L-shape in contact with the upper skin, the lower skin and a rib, a portion of the second part located in the chordwise direction being located in a space between the rib and a rear edge of the control surface.
A manufacturing method of a control surface of 16. an aircraft, the control surface comprising:
- an upper skin,
- a lower skin,
- ribs joining the upper skin and the lower skin and located along a chordwise direction of the control surface,
- wherein the manufacturing method comprises the steps of:
- providing a single composite preform comprising the upper skin, the lower skin and the ribs, and
- curing said single composite preform such that an integrated box comprising the upper skin, the lower skin and the ribs is formed,
- wherein at least a panel covering a joint of the integrated box and an integrated end along a span direction of the control surface is provided,
- wherein a non-metallic insert is provided along the span direction of the control surface between the upper skin and lower skin at a rear edge of the control surface;
- and,
- wherein a metallic profile is provided along the span direction of the control surface and covering the non-metallic insert at the rear edge.
