Aerodynamic fairing device, aircraft component arrangement with an aerodynamic fairing device and method for installing such a fairing part

An aircraft component arrangement with an aerodynamic exterior fairing device for creating an aerodynamic exterior cover for an area of an aircraft structure with a first section, a second section and a third section of the aircraft structure that is situated between the first section and the second section and realized in the form of a supporting component, with the exterior fairing device comprising:

• at least one first fairing part that has an outer side forming a first exterior flow contour and is composed of a fairing section designed for contacting a first section of the aircraft structure and a connecting section in certain areas, and
• a second fairing part that is composed of a fairing section that has an outer side forming a second exterior flow contour and is designed for contacting a second section of the aircraft structure and a connecting section in certain areas, wherein
• the connecting section of the first fairing part forms a joint piece that at least partially covers the second fairing part in an overlapping area,
• the contour of the outer side and the contour of the inner side of the connecting section of the first fairing part are at least sectionally adapted to one another with respect to their shape in the overlapping area,
• the first fairing part and the second fairing part respectively feature a mounting device for receiving at least one connecting element for thus connecting the fairing parts, and
• the shape of the second fairing part is realized in such a way that it contacts a third section of the aircraft structure on its inner side such that the first and the second fairing part can be mounted on the aircraft structure in the connected state by means of the at least one connecting element.
