Abstract: A wing flap sensor unit (2) having a position sensor (18) for detection of a rotation position of a shaft for operation of wing flaps and having a housing (4) which surrounds the position sensor (18), having an attachment component (20, 22) for attachment in an aircraft wing and having a connecting point (24) for an electrical connector of the position sensor (18). Hereby, the housing (4) is at least partially manufactured from titanium using a precision-casting method. The titanium precision-casting method makes it possible to achieve a particularly robust and lightweight housing.

Abstract: An input system (2) for a landing flap control of an aircraft. In order to make the input system (2) compact, light and reliable, it is provided with a selector lever (4) mounted pivotably by a shaft unit (10) for the input of a landing flap position, and a sensor arrangement (22) being arranged at one side of the selector lever (4) and having two mutually redundant optoelectronic sensor units (24) each for detecting a position of the selector lever (4), wherein a one-piece shaft element (40) of the shaft unit (10) is passed from the selector lever (4) through the sensor units (24).

Abstract: The invention relates to a housing for electronic units having printed circuit boards and heat sinks attached to said printed circuit boards. The housing comprises side walls formed by a first and a second u-shaped-section each having a central portion and a first and a second side cheek extending perpendicularly to the central portion. The u-shaped-sections extend into each other with clearance along longitudinal edges of the side cheeks. The central portions of the u-shaped-sections are connected to opposite end faces of the heat sinks. This results in an inexpensive construction with stability in dimensions. The heat transmission between the heat sinks and the housing is good.

Abstract: In a high-temperature protective arrangement for an electronic device, which as such generates heat, the electronic device is enclosed by a heat protective enclosure provided with gaps for permitting heat removal by air convection. The heat protective enclosure is coated with a material which is subject to swelling under the action of heat to a multiple of the thickness of the original coating whereby a heat-insulating layer is formed and the gaps are closed. Electronic components of the electronic device are disposed within a housing. The heat generated by the electronic components is passed to the housing which is surrounded at a spacing substantially on all sides by the heat protective enclosure.

Abstract: The invention relates to a housing for electronical components for two- or multi-channel systems. The housing includes a housing frame, which is separated by electrical screens into two or several electrically screened parts. At least two covers are detachably attached to the housing frame. The covers permit access to the electrically screened parts of the housing frame. Electronical components associated with each channel are arranged in a respective one of the electrically screened parts of the housing. It is possible to accommodate some of the electronical components in the covers. The covers can be provided with connectors.
