Claim:
1. A trailing-edge flap system for a wing of an aircraft, the wing having a wing structure, the trailing-edge flap system comprising: a trailing-edge flap; a straight guide rail attached to the trailing-edge flap; a carriage slidably engaging the guide rail and rotatably attachable to a fixed position on the wing structure; and a drive means coupled to the wing structure and to a first joint on the guide rail; wherein the drive means is adapted for moving the trailing-edge flap relative to the wing structure by moving the guide rail along the carriage by moving the first joint relative to the wing structure, such that the trailing-edge flap translates and rotates, and wherein the trailing-edge flap is at least movable into a cruise position, a high-lift position, and an air brake position; wherein the drive means comprises a rotary actuator, a drive lever attached to the actuator, a swing lever coupled with the drive lever, and a connection link coupled with the swing lever and the first joint; wherein the drive lever and the swing lever are configured for exclusively moving on a first plane with a fixed spatial relationship to the wing; and wherein the first joint is configured to be rotatable exclusively about a rotational axis that is substantially parallel to the first plane.
