Device for automatically controllable unloading of aircraft wings

DETAILED DESCRIPTION I claim: 1.
Device for automatically controllable off-loading of aircraft wings, which is arranged between an aircraft wing structure and at least one of control surfaces, spoilers and flaps for their actuation, characterized in that at least one of the device (1) is assigned to the at least one of said control surfaces, spoilers and flaps (12a) along a wing span, comprising a dampening circuit (2), including a power cylinder (3) with a piston (3a) and an elongated piston rod (4) having a first end connected to a load and a second end (5) remote from the load connected with a spring-loaded straight line crank drive (7) supported at the wing structure (6) and that the power cylinder (3) is equipped with a check valve (8) and with inlet- or outlet valves (9,10) and said valves are automatically controllable with respect to their opening or closing forces by means of a flight controller (11) depending on the respective flying weight and the mach number of the aircraft.
2.
Device according to claim 1, characterized in that the device (1) is arranged at a hydraulic or electrical servo drive (12) which can be decoupled from it, for the actuation of the at least one of the control surfaces, spoilers and flaps (12a).
3.
Device according to claim 1, characterized in that the inlet- or outlet valve (10) is controlled in such a way that it returns within a time span of 0.
5 to 10 seconds from the outlet position to the closed position.
4.
Device according to claim 1, characterized in that the straight line crank drive (7) is arranged in a chamber (15) filled with liquid and equipped with an additional inlet- or outlet valve (13) as well as with flexible gas pressure containers (14) whereby the additional inlet- or outlet valve (13) is automatically controllable by means of the flight controller (11) depending on the respective flying weight and the mach number with respect to the opening- or closing forces.
5.
Device according to claim 4, characterized in that the additional inlet- or outlet valve (13) is connected with a pressure accumulator (16), with the pressure being automatically controllable of the flight controller (11) depending on the respective flying weight and the mach number of the aircraft
