The present invention relates to a firearm projectile capable of releasing a secondary payload mid-flight through a pyrotechnic timing mechanism. Once the firearm is fired, the powder in the casing pushes out the projectile as a typical round. In addition, the powder ignites the delay column. The formulation and amount of delay pyrotechnics determines the delay time. When the delay column is burned, the final portion ignites an expelling charge. The expelling charge builds pressure in the projectile casing and separates the base plug from the main projectile housing. The expelling assembly pushes out the secondary payload out the rear of the projectile. Although the payload exits the rear of the projectile at minimum velocity, the net velocity of the payload is still in the forward direction.

A method for modifying a separable projectile between a test embodiment or an effect embodiment includes detaching the front projectile body from the rear projectile body, arranging a payload container in the front projectile body where the payload container comprises measuring equipment or an effect part, and fitting the front projectile body to the rear projectile body by way of a belt. A separable projectile which can be modified between a test embodiment and an effect embodiment is also provided.

A dividable parachute grenade is provided including a grenade casing, a nose cone, a detonating fuse, a dividing charge, a payload, a parachute device, a grenade bottom, and a supporting device, wherein the supporting device is annular and includes pretensioned sector elements fixed to a fixing ring in the recess on the inner side of the grenade casing, the sector elements are pretensioned with a tension ring arranged around the annular supporting device via recessed grooves in the sector elements, whereof the supporting device is arranged extensibly in the radial direction in a recess on the inner side of the grenade casing behind the payload and supports the payload in the extended position during the acceleration phase of the grenade, and stays in the grenade after the separation of the payload from the grenade.

Asteroid redirection and soft-landing systems are provided that use cosmic ray and muon-catalyzed micro-fusion. These systems include a micro-fusion propulsion system providing thrust for redirecting a small asteroid, as well as providing a particle cushion at a landing site for a soft-landing. The systems deploy deuterium-containing fuel material as a localized cloud interacting with incoming ambient cosmic rays to generate energetic fusion products. Dust or other particulate matter in the fuel material converts some cosmic rays into muons that also catalyze fusion. The fusion products provide thrusting upon the asteroid. The fusion products also aid deceleration of incoming asteroids to be mined for a soft landing upon a lunar or planetary surface.

The present invention relates to an arrow device with dual destructive function which provides a second extended destruction by explosion of explosives carried within the arrow device in addition to a penetrative destruction caused by kinetic energy of an arrow. The arrow device with dual destructive function comprises an arrow body and an arrowhead, wherein the arrow body comprises a hollow tube, the hollow tube is provided with an inertial body therein, the arrowhead is of a hollow structure and is provided with a hole structure communicating the hollow structure of the arrowhead with the outside. The hollow structure of the arrowhead is equipped with explosives or ammunition therein. An isolation mechanism is provided between the arrowhead and the hollow tube of the arrow body. A firing mechanism for firing explosives or ammunition is provided on the isolation mechanism or the front end of the inertia body.

The invention relates to an illumination munition, particularly an illumination payload ejection device housed within a common carrier payload delivery shell, with a frangible safety link. There is provided an illumination munition comprising a shearable tail unit, a main body which comprises a payload cavity for receiving an illumination payload apparatus, a fuze, an ogive element located between said main body and the fuze, and an explosive train operably connected to said fuze, wherein the illumination payload apparatus comprises an illumination composition, a drogue parachute and a main parachute, wherein the main parachute is tethered by a payload tether to the payload apparatus, such that after deployment of said main parachute said payload apparatus descends under the control of said main parachute.

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.

Disclosed is a rifle grenade using a bullet trap. A propellent assembly is formed with a first housing configured to house a trapping unit that traps a bullet shot from a gun to travel from rear to front and absorbs kinetic energy of the bullet, and a second housing configured to house a propelling unit that is disposed in front of the first housing, and is activated by the kinetic energy of the bullet which is absorbed into the trapping unit to provide a propelling force in a trajectory direction of the rifle grenade.
