A wing having a cantilevered support for changing the camber thereof is attached at a stressed wing portion so as to be pivotable about an axis rigidly attached to the wing. Sliding carriages having gear wheels are attached in a guide channel in the wing cantilevered support and a toothed rack attached at a landing flap is guided between the gear wheels so that the distance traveled by the sliding carriage can be selected to be different from the distance through which the flap travels during lowering or extension thereof. Actuation of the landing flap occurs by means of a hinged crank and a connecting rod which drives the sliding carriage and, in order to cover a gap between the flap and a spoiler which is provided, the spoiler is designed with a flexible configuration.

Wing with extendable flap and variable camber

A device for an automatically controllable off-loading of aircraft wings, arranged between the aircraft wing structure and the control surfaces, spoilers or flaps and is a single device or in the form of a plurality of devices respectively assigned to the control surface along the wing span and automatically reduces the additional loading at the aircraft wing generated by gust-and maneuver loads as well as increases the flutter speed by a dampening circuit in an electro-hydraulic manner.

Device for automatically controllable unloading of aircraft wings

A process of and a device for power- and air-conditioning fresh air generation in an aircraft, which are equipped with main power plants and an auxiliary power unit driving an air-conditioning compressor, both of which are supplied with air-conditioning exhaust air from the passenger- and/or pilot cabin and/or with exhaust air from the boundary layer suction for the purpose of economical operation.
