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 of an area of an aircraft structure, with the exterior fairing device comprising:

• at least one first fairing part that has an outer side forming a first exterior flow contour, the at least one first fairing part comprising a first fairing section and a first connecting section, and
• a second fairing part that has an outer side forming a second exterior flow contour, the second fairing part comprising a second connecting section,
• wherein at least a portion of the first connecting section of the first fairing part at least partially covers the second fairing part in an overlapping section,
• wherein a contour of the outer side and a contour of an 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 section,
• wherein 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,
• wherein the mounting device of the first fairing part and the mounting device of the second fairing part are each formed as at least one opening, wherein the mounting device of one of the first fairing part or the second fairing part includes at least one opening formed as an elongated hole that corresponds to an opening in the opposing section, and wherein the at least one connecting element is designed such that the at least one connecting element can be inserted into the openings of the two fairing parts in order to connect the fairing parts while still allowing selective movement of the first fairing part relative to the second fairing part, and
• wherein elongation of the elongated hole extends in a direction parallel to the outer side of the first or second fairing part, and the elongated hole is designed such that the selective movement of the first fairing part relative to the second fairing part is along the elongation of the elongated hole,
• wherein a shape of the second fairing part is realized in such a way that the second fairing part contacts the aircraft structure on an inner side such that the first and the second fairing part can be mounted on the aircraft structure in a connected state by the at least one connecting element, and
• wherein both fairing parts respectively feature at least one opening formed as an elongated hole and elongation of the respective elongated holes is perpendicular.

A method for installing an aerodynamic exterior fairing device on a structural component of an aircraft structure, the method comprising:

• providing at least one first fairing part and at least one second fairing part,
• arranging the second fairing part on and in a predetermined position relative to the structural component,
• arranging the first fairing part on the structural component such that an inner side of a first connecting section of the first fairing part at least sectionally lies opposite of an outer side of an overlapping section of a second connecting section of the second fairing part,
• mounting the first fairing part and the second fairing part on the structural component with a mounting device that is configured for receiving at least one connecting element for thus connecting the fairing parts,
• wherein the mounting device is formed as at least one opening formed as an elongated hole that corresponds to an opening in the opposing section, and wherein the at least one connecting element can be inserted into the openings in order to connect the fairing parts while still allowing selective movement of the first fairing part relative to the second fairing part,
• wherein elongation of the elongated hole extends in a direction parallel to the outer side of the first or second fairing part, and the elongated hole is designed such that the selective movement of the first fairing part relative to the second fairing part is along the elongation of the elongated hole, and
• wherein both fairing parts respectively feature at least one opening formed as an elongated hole and elongation of the respective elongated holes is perpendicular.
