Abstract: A display system for aircraft for showing the attitude, particularly the rolling and pitching position or the flight path angle, comprising a windshield projection device (HUD "HEAD-UP DISPLAY") with devices for generating and displaying an airplane symbol, a symbol which is stabilized fixed to earth for the displaying of the position of the true horizon as well as for generating and displaying symbols for the rolling and pitching angle or of the path angle in the exterior field of view of the pilot as a function of the values measured by the corresponding instruments. In this case, a display of the attitude is generated by means of a reference symbol representing the airplane and an information symbol which changes with respect to the reference symbol in its position and shape--and is dependent on the rolling angle (.phi.) and pitching angle (.theta.) or path angle (.gamma.).

Abstract: A superconducting tunnel element, having a plurality of super conductors separated by barriers, the superconductors each comprising two physically separate but electrically connected superconducting layers and one insulated control layer. As a result, summation of the detection capacity or of the transmitting intensity becomes possible. Also, the simultaneous detection or transmission is permitted on arbitrary different frequencies or a summation of the signal intensity is possible in the case of SQUID-systems.

Abstract: A cutting tool for making cylindrical bores includes two or More cutting inserts and radially or approximately radially directed blades which leave an uncut core, as well as chip removal devices extending in the axial direction of the tool. The cutting tool is composed of at least two coaxial parts. One part forms the boring crown with the cutting inserts, and the other part forms the support for the boring crown with a clamping shank. The chip removal devices extend axially along both parts and lead radially to the outside.

Abstract: A process for generating distance images operates by the emission of light pulses and the synchronized time-delayed reception of the reflected light pulses on an image receiving unit with a shutter device connected in front of it. During the reception of a reflected light pulse, the transparency of the shutter device passes through a given time-dependent function and in this manner at least two such modulated reflection images are generated while different transparency functions are used. A color is assigned to each of these images, and the colored images are superimposed to form a false-color-coded distance image.

Abstract: The camera includes two functionally equivalent line and field scanners, one for issuing a light pulse that will be returned by an object point, and identified by a particular line/field scanning position in both scanners; the second scanner being attuned to recognize the returned light in one scanning raster point only for purposes of correlation. The field scan is realized through a deflecting mirror or in a columnal array the line scans are either solid state or fiber optics.

Abstract: A method of using a method for navigating and updating of navigation for aircract under utilization of sensor image processing and reference store data, for purposes of automatic or assisted landing is disclosed.

Abstract: A fiber optic scanner includes two fiber bundles, each transforming a linear array into a circular one. The circularly arranged bundle ends cooperate with synchronously rotating deflectors which, in conjunction with single line fiber optics couple a deflector to a light source, provided the linear ends of the two bundles are positioned to be coupled to each other through a field of view.

Abstract: In an aircraft having a cylindrical or tapered pressurized fuselage, an internal bulkhead includes a central calotte shaped part of particular thickness and made of a fiber-mesh, a woven or a fleece-like reinforcement of a particular radius of curvature and preferably made of Kevlar: a possibly thicker edged portion of, preferably, carbon fiber-reinforced material, which possibly matches any taper of the fuselage, and a transition from the calotte shaped part to the edge having a radius of curvature smaller than the particular radius of the calotte shaped partition.

Abstract: A method for aircraft navigation which includes, sensor signal processing with refernce data. The method provides for sensing and range finding the elevational profile underneath the craft. Those elevational data are fed to a segmentizing and type classifying unit whose output in turn is fed to a classifying unit, and that the position of the craft is determined by comparing the segmentized overflight strip with corresponding topographic features in reference information.

Abstract: A flying boat or sea plane has a wing system in order to obtain hydrodynamic lift when protracted and including two wings arranged one above the other but establishing, in front view, a closed frame; the wing system can be retracted into the fuselage of the vehicle by turning the wings upside down and pulling them into the fuselage using a three-group lever system.

Abstract: A device for the bending and deformation of panels such as skin elements for covering cells of vehicles in the aerospace industry such as aircraft, rocket space vehicles or the like, the skin elements having inwardly directed stiffening ribs which intersect in nodes; the device has first and second deforming members being capable of engaging the skin element in points adjacent to nodes under consideration of length changes obtained by some of the ribs; the two deforming members are adjustable in relation to each other and other through a variable armature mount such that the deforming forces respectively provided into the part to be deformed are oriented in the area of the nodes transversely or nearly transversely to those ribs which extend transversely to the curvature to be obtained and consistently tangentially to the panel part in the direction of curvature and following change of curvature on account of bending; and the direction of force action as provided by the deforming members into the work part is
