The present invention is a canister-launched pyrotechnically actuated folding wing UAV. The invention features a method for reliable and irreversible locking of a foldable wing, while enabling compact storage, cost reduction, ease of deployment and aerodynamic performance unattainable in current folding-wing designs. In a specific embodiment, the UAV is pre-packaged in a deployment canister for single-button deployment. The UAV can be offered in a rental system in which part or the entirety of the device can be returned for refurbishing. Additionally, the device can be provided as a fully expendable unit.

A projectile such as a paintball including a ball-shaped capsule and a round-shaped disc capable of facilitating accuracy of projectile travel direction is disclosed. The ball-shaped or substantial ball-shaped capsule, in one embodiment, having a head and a tail is able to store and deliver colored markers upon an impact between the projectile and an object. The round-shaped disc is positioned at a place so that allowing a portion of the round-shaped disc to extend above outer surface of the capsule. The disc is able to catch at least airflow when the projectile is launched. The round-shaped disc, in one example, uses the direction of the airflow to facilitate travel direction of the projectile.

According to a first aspect of the invention, there is provided a programmable system for a munition, comprising: an electroacoustic transducer, arranged to receive an acoustic signal comprising data, and convert that signal into an electrical signal comprising data; a processor, arranged to receive and process the electrical signal comprising data, and to use that data in programming of the programmable system.

The invention relates to a fin deployment mechanism (1) comprising a base unit (3), deployable fins (8) movably arranged on the base unit (3) and, in the retracted position, bearing against the base unit (3), as well as a gas-generating device, in which the fins in the retracted position are fixed to the base unit, and in which at least one gas duct (6, 7) is arranged in the base unit (3) so as to conduct pressurized gas generated by the gas-generating device to the bottom side of the fins (8), which in the retracted position bear against the base unit (3), in order to create a force which acts on the fins (8) for deployment of the same (8′). The invention further relates to an artillery projectile comprising a fin deployment mechanism.

A pivot connection part for a flying machine includes an inner body, an outer body radially surrounding the inner body, and a set of connection elements configured to connect the inner body to the outer body. Breaking the connection elements detaches the inner body from the outer body. A first blocking assembly having a cam and a stop is configured to block relative rotation between the inner and outer bodies in a first rotational direction. A second blocking assembly having a pawl and a resilient stop blade is configured to block relative rotation between the inner and outer bodies in a second rotational direction.
