Embodiment Construction
[0039] figure 1 Shown is part of a high-lift system arranged on a wing 20 of an aircraft comprising lift elements in the form of leading-edge flaps 21 and trailing-edge flaps 22 . Said lifting elements can be passed in a suitable manner known per se respectively in the figure 2 The drive system 23 , 24 shown in FIG. 2 is extended and retracted, said drive system generally comprising at least two drive units 23 and a mechanical drive connection 24 coupled to the flaps 21 , 22 . The control of the lift flaps 21, 22 is carried out in figure 2 shown in the flap control unit 26, which is functionally connected to the drive system 23, 24 via the control connection 25, so as to adjust the control position according to the obtained control instructions via the suitable mechanical connection 24. figure 2 Lifting elements generally indicated by reference numerals 21, 22 in .
[0040] The flap control unit 26 can be realized in software form as part of an on-board computer 28 which...

The invention relates to the automatic control of a system of high lift elements (21, 22) of an aircraft, which can be adjusted into a retracted and several extracted configuration for travel flight, holding flight, takeoff or landing, comprising a flap control unit (26), which is connected in a functionally effective manner to the high lift flaps (21, 22) using a drive system (23, 24) via a control connection (25), and an operating unit (7) that is connected to the flap control unit (26) for the input of operating commands influencing the adjustment of the high lift elements (21, 22). According to the invention, the flap control unit (26) is provided to calculate the respective configurations of the high lift elements (21, 22), the direction of the configuration change, and the operatingmodes of switching speeds associated with the automated components for adjusting the high lift elements (21, 22) as a function of flight status data and additional data relevant to flight operation, wherein the flap control unit (26) may also automatically carry out a switching of operating modes for the takeoff or landing flight, and is provided to automatically generate the instructions commanding the configuration change as a function of the flight speed.
Description
technical field [0001] The invention relates to a device for automatically controlling a high-lift system of an aircraft according to the preamble of claim 1 . Background technique [0002] Various high-lift systems are known for increasing the maximum lift on the wing for take-off, landing and slow flight. These high-lift systems are used in commercial traffic aircraft and other transport aircraft, but also in business travel aircraft and engine-powered sport aircraft. In civil traffic and other transport aircraft, high-lift systems are used with wing leading-edge flaps and wing trailing-edge flaps as the main aerodynamically active lift elements. Wing leading edge flaps are designed with or without a gap between the flap and the main wing, while wing trailing edge flaps are mostly designed as single gap or multiple gap trailing edge flaps. [0003] The actuation of such flaps or lifting elements has hitherto generally been carried out manually via an operating handle in ...
