A method and apparatus for manufacture of a profile element

Abstract: A method and an apparatus for manufacturing of a profile element including a web portion, a first and second flange portion, which extend from the web portion and are disposed essentially opposite each other. The method includes folding a blank of composite material about a first and second flange forming surface of a forming tool. The method includes setting at least one flange forming surface of a forming tool a distance from another flange forming surface greater than a desired distance between inner surfaces of the flange portions of a finished profile element. The folded blank is cured and a gradual decrease of the distance between the flange forming surfaces is simultaneously controlled. The cured profile element is removed from the forming tool.

Case-based reasoning applied to geometric measurements for decision support in manufacturing

Abstract: Measurements from products are continuously collected to allow adjustments in the production line to certify a feasible product quality. Case-based reasoning is a promising methodology for this type of quality assurance. It allows product measurements and its related adjustments to the production line to be stored as cases in a case-based reasoning system. The idea is to describe an event of adjustments based on deviations in geometric measurement points on a product and connect these measurements to their correlated adjustments done to the production line. Experience will implicitly be stored in each case in the form of uniquely weighted measurement points according to their positive influence on adjustments. Methods have been developed in order to find these positive correlations between measurements and adjustments by analysing a set of historical product measurement and their following adjustments. Each case saved in the case base will be "quality assured" according to this methods and only cases containing strong positive correlations will be used by the system. The correlations will be used to supply each case with its own set individual weights.

Method of arming and arrangement for carrying out the method

Abstract: A method and apparatus for determining whether a warhead in flight and forming a part of a rocket, missile, or the like, is in a state which permits arming of the warhead. The arming of the warhead depends upon the conditions of the warhead's movement and the elapsed time from its launching. A specific time slot which begins at a predetermined time after the launching of the warhead and terminates at a predetermined time thereafter is demarcated. The velocity of the warhead is measured following its launch and at least during the specific time slot. The warhead will be armed only in the event that the measured velocity of the warhead has reached at least a predetermined value within the specific time slot.

Wide-band spatially distributed TE10 substrate integrated waveguide transition for high-power generation at mm-wave frequencies

Abstract: An array of microstrip lines is used for the direct excitation of the spatially distributed TE10 substrate integrated waveguide (SIW) mode. The proposed configuration can generate 4x more power with a 4x smaller form factor relative to a single microstrip-to-SIW transition, while offering a larger bandwidth. This is an important step toward the generation of high power in densely integrated mm-wave antenna systems.

Use of a helical tool and a method for producing a surface member comprising at least one stiffening member

Abstract: A helical tool (1', 1") having a rigid outer helical support surface (2) is used as support for a non-rigid material for producing a hollow elongated member onto and as an integral part with a surface member (3) in manufacturing of a surface member having at least one hollow elongated stiffening member integral therewith.
