Abstract: An aircraft high lift airfoil arrangement guiding element includes a first part configured to be fixed to a first edge member or rib of the airfoil arrangement, and a second part including a track support element to movably support a track device of a second edge member or slat of the airfoil arrangement. The second part is mounted to the first part to move from a first to a second position. A biasing device biases the track support element in the spanwise direction towards the track device. The airfoil arrangement is produced by providing the first edge member or rib, rigidly attaching thereto guiding elements to guide the movable track device supporting the second edge member or slat, and attaching the track device to the first edge member. During installation, a surface of the track device is pressed against a movable track support element biased against the track device.

Abstract: For production of a propellant charge powder, especially for medium and large calibers, in a process in which the solid is incorporated together with a liquid in a mixing and drying process into the channels of a granular green material and compacted therein to form a plug, the solid, under otherwise identical process conditions, is set within a setting range of >0-0.5% by weight based on the weight of the granular green material. For more significant lowering of the maximum pressure within an upper temperature range and for more significant raising of the maximum pressure within a lower temperature range of the application temperature range, an increased amount of solid is used. The solid is a substance whose melting point is at least 10° C., especially 20° C., above a maximum use temperature of the propellant charge powder and which is inert toward the granular green material. Since the plug consists virtually exclusively of inert material, a high ballistic stability is achieved.
