Seal plate for an aerodynamic surface

An aerofoil assembly comprising:

• a fixed part having a first aerodynamic surface;
• a moveable control surface mounted to the fixed part and having a second aerodynamic surface;
• a seal plate including:
• a first resilient material having a third aerodynamic surface extending between the first and second aerodynamic surfaces, wherein the first resilient material includes a first edge mounted to the fixed part and a second edge, opposite to the first edge, slidably engaging the movable control surface;
• the second edge defining a sealing surface configured to sealably contact the movable control surface,
• a rigid lever configured to transfer a bending moment from the movable control surface to the seal plate whereby the bending moment bends the seal plate, and
• a step at the second edge and between the rigid lever and the first resilient material, wherein the step offsets the rigid lever from the third aerodynamic surface and slidably engages a side of the movable control surface opposite to the second aerodynamic surface,
• wherein the first resilient member, the second edge, the rigid lever and the step are a single piece device.

An airfoil assembly comprising:

• a fixed wing having a first aerodynamic surface and a trailing edge;
• a seal plate including a leading edge region fixed to the trailing edge of the fixed wing, a resilient panel extending in a chordwise direction back from the leading edge region, and a rigid lever extending back in the chordwise direction from the resilient panel;
• and
• a moveable spoiler including a leading edge, a third aerodynamic surface extending from the leading edge of the spoiler in the chordwise direction and an underside surface opposite to the third aerodynamic surface;
• wherein the resilient panel includes a second aerodynamic surface aligned with the first and third aerodynamic surfaces along the chordwise direction;
• wherein the rigid lever is joined to a trailing edge of the resilient panel by a step which joins the rigid lever to the resilient panel;
• wherein the step offsets the rigid lever out of a plane of the second aerodynamic surface;
• wherein the rigid lever slidably engages the underside surface of the spoiler such that the engagement bends the resilient panel, and
• wherein the seal plate is a single piece device including the leading edge, the resilient panel, the rigid lever and the step.
