System for driving a flap arrangement between a retracted position and an extended position

A flap system for driving a leading-edge flap between a retracted position and an extended position, the system comprising:

• a leading-edge flap having a first flap joint and a second flap joint,
• a first scissor link,
• a second scissor link,
• a first connecting link, and
• an actuator,
• wherein the actuator is coupled with either the first scissor link or the first connecting link,
• wherein the first scissor link comprises a first support joint for rotatably supporting the first scissor link on a first structurally fixed point, wherein an end of the first scissor link opposed to the first support joint is coupled with the first flap joint,
• wherein the first connecting link comprises a second support joint for rotatably supporting the first connecting link on a second structurally fixed point and wherein an end of the first connecting link opposed to the second support joint is rotatably coupled with an end of the second scissor link,
• wherein an end of the second scissor link opposed to the end coupled with the first connecting link is coupled with the second flap joint,
• wherein additionally the first scissor link and the second scissor link are rotatably coupled to each other to form a scissor arrangement,
• wherein the actuator, the first scissor link, the second scissor link and the first connecting link are arranged to actively place the leading-edge flap from a retracted position into an extended position
• wherein the first scissor link is coupled to the flap through a second connecting link, which is rotatably supported to the first scissor link and rotatably supported to the first flap joint, and
• wherein the second connecting link has a length less than a third of the length of the first connecting link.
