Various embodiments include a method for feeding DC power to an amplifier module for a pulsed load, comprising: providing current pulses from a DC power supply; charging a capacitor configuration in the amplifier module; providing an output voltage via a voltage regulated power supply; feeding current pulses to said load from said capacitor configuration, determining an output current (Iout) pulse configuration appearing during feeding the load from said configuration; providing a pulsed input current (Iin) from said DC power supply based upon the determined output pulsed current; limiting the maximum current level of the input current pulses to a pre-determined level by, inter alia, a control and pulse shaping circuit (8) to be substantially lower compared to the peak current of said output current pulses. Various embodiments include a device for feeding DC power.

A missile launching system including a launch rail for attachment to an aircraft and having a longitudinal slot, and at least two hangers for attachment to the missile at longitudinally spaced locations thereof and having a cross-section configured to be received in the longitudinal slot in the launch rail. The rearmost hanger includes two separable main parts, including a first main part for engagement with a respective lateral, first groove section of the slot, and a second main part configured to be attached to the missile and be slidably guided in a second groove section of the slot normal to the first groove section and opening towards the missile. The second main part includes laterally extending collars configured to interact in close proximity with respective rail sections facing the missile. The second main part is configured to separate from the first part when launching the missile.

A method in an automated system for handling at least two versions of an application. The system includes a controller for automation of a process with the application stored thereon in bidirectional connection with a communication server. The communication server is in bidirectional connection with at least two clients. The method improves communication between a communication server and several clients. Graphics and images can be displayed without reconfiguration when a new version of an application is used.

A tool assembly including a male tool including an inner shape tool including a bag having a connection connectable to a depressurization source for providing a vacuum in the bag such that beads therein form a body of firm cohesion providing the inner shape tool rigid. The male tool further includes a flexible, hollow curing support arranged around the rigid inner shape tool, the inner shape tool is arranged to be removable from the flexible, hollow curing support by rupturing the vacuum.

An active input matrix balun and a method for the same. The matrix balun has one input transmission line with an RF-in terminal for receiving a single ended RF-in signal and a first output transmission line with a first RF-out terminal and an adjacent second output transmission line with a second RF-out terminal. Two balanced RF-out signals at the first and at the second RF out terminal, where each RF-out signal has an amplitude level equal to or exceeding the amplitude level of the Rein signal and where the RF-out signals have a mutual phase difference of 180° and are of equal amplitude levels.

An electronic counter measures solution. Jamming signals are emitted towards a threat to improve chances of survival for at least two vehicles, which are physically separated from one another, however associated with one another in a group. Each of the at least two vehicles receives a wireless time reference signal from an external resource. The vehicles exchange messages over a wireless data link. The messages pertain to usage of at least one electronic warfare resource in each vehicle. Based on the messages and the time reference signal the usage of at least one first electronic warfare resource in a first vehicle is coordinated with the usage of at least one second electronic warfare resource in a second vehicle, such that a particular type of jamming signal is emitted alternately either from the at least one first resource or from the at least one second resource, essentially without any overlaps or gaps in time. Thereby, a false target is created between the vehicles with respect to a weapon which operates in a so-called Home-on-Jam mode.
摘要:
A method and an apparatus for manufacture of an elongated beam profile element including a recess configured to accommodate a support element. The method includes forming the blank into the web portion with at least one first protrusion formed to extend across the web portion and to protrude outward from the web portion's outer surface; and into the first flange portion with at least one second protrusion formed to extend across the first flange portion and to protrude inward from the first flange portion's inner surface, wherein this second protrusion merges into the first protrusion and constitutes the recess for accommodating the support element under a wing.
摘要:
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.

An antenna structure integrated in a hull or fuselage. The hull or fuselage can be the outer surface of an aircraft, artillery shell, missile or ship. The antenna structure includes an array antenna. The array antenna includes a number of antenna elements. Each antenna element includes a radiator and an RF feed. The antenna elements are arranged in a lattice within an antenna area including a central antenna area and a transition region outside the central antenna area wherein a number of the antenna radiators as well as resistive sheets are arranged in substantially the same plane as a surrounding outer surface of the hull or fuselage.
