Disclosed techniques relate to fragment launching. In an example, a fragment launcher has a casing, a launch aperture and a detonation position. An inner profile of the casing tapers from the main body towards the fragment launch aperture and from the main body to the detonation position. A fragment is held within the launch aperture such that when in use an explosive charge can be initiated to launch the fragment from the launcher. The launcher is particularly suited to uses where there is a requirement to launch a fragment in a consistent and repeatable manner.

[Problem] Provided is a method for manufacturing an assembly including an igniter, a projectile, and a cylinder that is easy to assemble. [Solution] A method for manufacturing an assembly included in an electric circuit breaker device, the assembly including an igniter, a projectile, and a cylinder, is a method for disposing a projectile and an igniter in a cylinder of an electric circuit breaker device, the method including: a first step of preparing a cylinder having a first opening, a plurality of through holes formed at intervals in a circumferential direction in a peripheral wall portion on a first opening side, and a second opening, and disposing a projectile in the cylinder; a second step of disposing an igniter main body portion in the cylinder and then disposing the cylinder in a mold; a third step of injection-molding a resin from the first opening side of the cylinder to form a resin portion; a fourth step of removing the cylinder including the projectile and the igniter from the mold; and a fifth step of crimping a peripheral wall portion on the first opening side of the cylinder to fix the resin portion of the igniter.

A winged external guidance frame placed on the muzzle that can couple with a projectile while exiting the barrel utilizing the kinetic energy of the projectile to travel to the target while the accuracy is provided by on board electronics and corrected using the wings. Alternately a reusable unmanned aerial system that travels in the speed and direction of the projectile and couples with the projectile as it exits the barrel.

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).

The present invention concerns a method for launching a payload (3) by means of an arrangement (1), which is configured for storing and launching a payload (3). A launch compartment (5) of the arrangement (1) is configured to eject the payload (3) from the launch compartment (5) via a push-out chamber (7) to an airflow (AF), which during use of the arrangement (1) flows over an aerodynamic surface (9) of the arrangement (1). An air intake (13) is formed in the aerodynamic surface (9) and is coupled to the push-out chamber (7) and/or launch compartment (5) via an internal air transfer arrangement (17) comprising an openable closure member (11) configured to close and open the internal air transfer arrangement (17).

A test system is disclosed that has a chassis, a throwing mechanism that is located at an upper part of the chassis onto which at least one weight is attached and provides throwing the weight attached thereon, a base that is located at a lower part of the chassis and onto which a weight is thrown by the throwing mechanism, a control unit that provides throwing the weigh through the throwing mechanism, and a position adjuster is located on the base or chassis and provides aligning the weight thrown onto the base on the base.
