A wing, in particular a airfoil of an aircraft, with a variable profile shape, which wing comprises a first skin and a second skin and a supporting structure, arranged between the first and the second skin, which supporting structure in the direction of the wing depth extends between a first end and a second end, wherein the form of said supporting structure, for the purpose of varying the profile shape by means of a drive device comprising drive elements, is variable. The supporting structure comprises ribs, arranged one behind the other in the direction of the wing depth, which ribs at connection positions are interconnected so as to be articulated, wherein said ribs at first connection positions are connected to the first skin, and at second connection positions are connected to the second skin. For the purpose of setting the variable profile the mutual spacing of the second connection positions can be varied by means of the drive elements.

A process for testing the tightness of containers includes making available a first fluid in the container interior space that is different from a second fluid surrounding the container, creating a negative pressure in the container interior space, testing the interior surfaces of the container side wall for traces of second fluid penetration, and possibly localizing any entry points.

Lift flap mechanism for adjusting a lift flap assigned to an airplane wing by means of a driving system, the lift flap mechanism comprising a main connection mechanism and a secondary connection mechanism in the form of a guide lever disposed in an articulated manner on the lift flap and the flap track, the main connection mechanism having a steering lever arrangement with at least one steering lever which has a first steering lever joint and a second steering lever joint, the at least one steering lever by way of a pendulum coupled to the first steering lever joint being connected with the flap track, and the second steering lever joint being guided such that, by means of a defined angular position of the at least one steering lever, the positions of the main connection joint and of the secondary connection joint are unambiguously determined.

A fluid actuating drive for relative translational movement of first and second structural parts has a housing filled with a pressurizing medium, which in its longitudinal direction, runs along a gap that separates the structural parts, and is connected therewith. The width of the gap is dependant upon the relative position of opposing side walls of the housing, which side walls can be moved against one another with a pressurizing agent for the relative movement of the structure, where the side walls are alternately connected to the first and second structural part across the gap.
