摘要： A spring device for securing a threaded fastener of a bolted joint. The spring device includes at least one ring-shaped portion and a plurality of elongate spring elements. Each spring element is attached at least in a first end to the at least one ring-shaped portion. The at least one ring-shaped portion and a body formed by the plurality of spring elements have a common centre axis. Each spring element includes an inner peripheral surface directed towards the centre axis, and wherein a first portion of said inner peripheral surface is closer to the centre axis than are other portions of said inner peripheral surface and closer to the centre axis than an inner peripheral surface of the at least one ring-shaped portion.

摘要： The present invention relates to a director mount arrangement for automatic alignment of a subsystem relative to a platform, wherein said director mount arrangement is arranged to pivotably support the subsystem. The director mount arrangement comprises a pivot frame arrangement and a control system. The control system comprises a control unit arranged to generate control signals so as to control the orientation of and stabilize the subsystem. The control signals are generated based on angular rate of subsystem and orientation operating commands provided from an operator. The control unit further generates estimated control signals based on platform orientation information and determine a difference between the control signals and the estimated control signals, wherein the difference is indicative of mechanical misalignments between the subsystem and the platform. The control unit further generates alignment corrections based on the determined difference so as to automatically align the subsystem relative to the platform.

摘要： Provided is a heat generating arrangement and a method for generation of heat to be used in a heat consumer. The heat generating arrangement uses combustion of aluminium and hydrogen to raise the temperature of superheated steam inside the heat generating arrangement. The heat in the superheated steam can thereafter be used in a heat consumer, such as a heat exchanger.

The method comprises accessing (310) surrounding information from a database. The surrounding information is photo-based and three-dimensional. The method further comprises processing (320) the accessed surrounding information so that a perspective view of the surrounding of the aircraft is provided. The perspective view of the surrounding correlates to the position of the aircraft and is photo-based with spatially correlated photo-based textures. The method further comprises transmitting (360) the provided perspective view of the surrounding of the aircraft to a displaying unit so that it can be displayed in the aircraft. The present disclosure also relates to a system, an aircraft, a use, a computer program, and a computer program product.
