A flap system for an aircraft includes a flow body, a trailing flap and a movement means. The flow body includes an upper surface and a lower surface, the lower surface having a recess. The movement means is attachable to the flow body and the trailing flap. The trailing flap includes a shape that corresponds to the recess in the lower surface. The movement means is adapted for conducting at least a chordwise movement of the trailing flap such that it is movable out of and into the recess of the flow body in absence of a gap between the leading edge of the trailing flap and the flow body. Thereby, a clear increase in a lift coefficient may be achieved, while at the same time maintaining a low complexity and a high reliability of the flap system.

Disclosed herein is an exemplary embodiment of a system for driving a slat of an aircraft. The system includes first and second hinge support elements of a wing structure, a first arm device, a second arm device, and a third arm device. Also disclosed is an aircraft having the system, an aircraft wing having the system, and a method for driving a slat of an aircraft. The system utilizes a particular configuration of connection junctions, which rotatably connect the arm devices and the hinge support elements.

A wing for an aircraft is disclosed including a main wing, a slat, and a connection assembly movable connecting the slat to the main wing. The connection assembly includes an elongate slat track, wherein the front end of the slat track is mounted to the slat, wherein the rear end and the intermediate portion of the slat track are mounted to the main wing by a roller bearing including a guide rail mounted to the main wing and a first roller unit mounted to the rear end of the slat track and engaging the guide rail. The roller bearing includes a second roller unit mounted to the main wing and engaging an engagement surface at the intermediate portion of the slat track

A seal for sealing a space between a first structure and second structure. The seal includes a seal base configured to couple with the first structure so as to form a respective seal with the first structure, a resilient lattice body coupled to the seal base, and a cover. The cover includes an inner surface coupled to the resilient lattice body in an opposing relationship relative to the seal base so that the cover moves towards and away from the seal base in a biasing direction of the resilient lattice body, and a bulbous outer surface configured to engage the second structure so as to form a respective seal with the second structure.

A variable camber trim unit (100) comprises a housing (124), an input gear (102), and an output gear (108). The input gear (102) and the output gear (108) are rotatably supported by the housing (124). The variable camber trim unit (100) is selectively configurable to one of a coupled configuration or a decoupled configuration. When the variable camber trim unit (100) is in the coupled configuration, rotation of the input gear (102) relative to the housing (124) causes rotation of the output gear (108) relative to the housing (124). When the variable camber trim unit (100) is in the decoupled configuration, rotation of the input gear (102) relative to the housing (124) does not cause rotation of the output gear (108) relative to the housing (124), and the output gear (108) is capable of at least 5° and no more than 15° of rotation relative to the housing (124).
