Arrangement for storing and launching payloads

Abstract: The invention relates to an arrangement for storing and launching payloads (5), comprising an elongate body (8) provided with at least one launch opening (10) used for storing the payloads (5) in compartments (11.1,11.2,..., 11.n). The compartments (11.1, 11.2,..., 11.n) are provided with openings (12.1,12.2,..., 12.n). The arrangement being designed to be mounted on a vehicle (1) and with the longitudinal direction of the elongate body (8) essentially coinciding with the direction of motion of the vehicle (1). The elongate body (8) is provided with deflection means (15.1, 15.2...15.n) for acting on the air stream and for permanently creating an air covering layer across and over the compartment openings (12.1, 12.2,..., 12.n) during use.

Propellant charge for recoilless gun

Abstract: A propellant charge for a recoilless gun, in particular a propellant charge for a round of a reloadable support weapon. The propellant charge is cylindrically shaped and adapted for loading into a charge chamber formed between an inner casing and an outer casing of the round.

Industrial Application of Robust Aeroelastic Analysis

Abstract: EROELASTIC analysis and flight flutter testing (FFT) are central and important topics in aircraft airworthiness assessment. Confident results from numerical analysis are necessary in order to obtain an efficient and reliable flutter clearance process. There are, however, numerous sources of model uncertainties involvedinaeroelasticanalysis.Theaerodynamicsareoftenclaimed to be the most dominant source, but structural uncertainties in terms of variations in mass and stiffness properties may sometimes also be significant; see Pettit [1]. Considering FFT, this is an expensive activity that could be associated with high risk. Here as well, a systematic and reliable experimental procedure is required to obtain confident experimental data in a safe yet efficient manner. The number of gathered data points from fight testing is usually very limited. This fact often makes robust analysis methods based on statistics less usable in practice.

Method for manufacturing beams of fiber-reinforced composite material

Abstract: A method for manufacturing a hollow load-bearing beam structure of fiber-reinforced composite material. The method includes preparing a first lay-up of a first plurality of layers, and a second lay-up of a second plurality of layers. The first and second lay-ups are positioned on different sides of a mandrel and formed to a beam structure by bending the lay-ups against the mandrel, such that the side edges of the respective layers of the first and second lay-ups are arranged as offset butt joints in the circumferential direction of the formed beam structure.
