High-lift device connection assembly as well as wing and aircraft equipped therewith

A high-lift device connection assembly configured to movably connect a high lift device to a wing of an aircraft, the high-lift device connection assembly comprising:

• a track configured to hold the high-lift device and configured to extend forward of the wing, wherein the track includes an upper flange, a lower flange and at least one web connecting the upper flange to the lower flange and substantially perpendicular to the upper flange and the lower flange;
• a guide arrangement configured to be fixed to a structure of the wing and configured to guide forward and backward movement of the track, wherein the guide arrangement includes:
• an upper main roller configured in rolling contact with an upper surface of the upper flange and a lower main roller in rolling contact with a lower surface of the lower flange, wherein the upper main roller and lower main roller support the track;
• side guidance elements each engaging an edge region of the upper flange or the lower flange, and
• a track catcher configured to bear a load imposed by the track on the guide arrangement, the track catcher and the track catcher includes a first hook element and a second hook element each adjacent a bearing surface, wherein the bearing surface is a lower surface of the upper flange or an upper surface of the lower flange,
• wherein the first hook element extends towards a first side of the at least one web and the second hook element extends towards a second side, opposite the first side, of the at least one web, and
• wherein a clearance exists between the bearing surface and each of the first hook element and the second hook element while the upper and lower main rollers are operating in a non-failure mode, and at least one of the first hook element and the second hook element is in sliding contact with the bearing surface while at least one of the upper and lower main rollers are in a failure mode.
