Flap System For An Aircraft, Method For Adjusting The Lift Of An Aircraft And Aircraft Comprising A Main Wing And At Least One Flap System

摘要

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.
