    摘要: A liner for a shaped charge including an inner layer made of a material having a density below 10.5 g/cm3, and an outer layer made of a material having a density below 2.0 g/cm3, wherein the outer layer is formed directly on the inner layer. In a first state, both the inner layer and the outer layer are compressed towards the symmetry axis (x) of the liner, thereby forming a projectile. In a second state, the inner layer forms a penetration jet of the projectile and the outer layer forms a slug of the projectile. The melting point of the outer layer is above 100° C. The invention also concerns a shaped charge including the liner, a method for manufacturing the liner and a method for detonation of the shaped charge.

    摘要: The present invention concerns an arrangement (1) configured for storing and launching a payload (3) and a method for launching the payload (3) from the arrangement (1). A body (9) of the arrangement (1) comprises a compartment (15) configured to store and eject the payload (3). An aerodynamic surface (11) of the body (9) is provided with a launch opening (13) comprising a guideway (17) extending from the compartment (15). A sliding portion (12) of the payload (3) is configured to slide along the guideway (17) and through the launch opening (13) upon ejection. The extension of the guideway (17) inclines with an acute angle (α) relative the normal (N) to the centre line (CL) of the elongated body (9).

    摘要: Provided is a dual-band multimode antenna feed for a high-frequency band and a low-frequency band. The feed includes four high-frequency waveguide ports, where each high-frequency waveguide port is connected to a respective high-frequency input/output waveguide. Each high-frequency input/output waveguide includes a high-frequency waveguide aperture facing a first section for mixing electromagnetic modes in the E-plane. The first section is connected to a second section for mixing electromagnetic modes in the H-plane. The feed further includes a low-frequency waveguide port connected to a low-frequency input/output waveguide. A filter is arranged inside the first section to be transparent for plane wave modes exhibited at lower frequencies and reflecting for plane wave modes exhibited at higher frequencies.

    摘要: An ejecting system for dispensing countermeasure boxes includes a container arranged to hold a multiple of stacked boxes. A pushing actuator is arranged to push at one end of the stack of boxes in a first direction. The system further includes an ejecting mechanism including a driving actuator connected to a rotating member. The rotating member is arranged to engage with a box and on the side of the box most distant from the pushing actuator such that said box is moved in a second direction perpendicular to said first direction, and ejected.
