A single use diversionary device having a semi-hollow barrel with a closed first end forming a pressure-resistant bulkhead and a second open end that receives one or more powder filled cartridge assemblies. A pivotable gate is mounted at the second open end of the barrel and configured to direct an explosion in more than one direction. A cap containing electronic delay circuitry is attached to the first closed end.

In order to obtain an explosive smoke grenade, which can be fired from a portable anti-tank weapon, in particular a recoilless infantry weapon, and permits an enemy position or a vehicle to be fogged as quickly as possible, so that the enemy has only a very limited radius of action, a explosive smoke grenade is provided with a time fuse that can be programmed such that the burst charge detonates in the direct vicinity of the enemy position but before the grenade has reached the ground, and releases the smoke-generating active material. In addition, the pyrotechnic active substance arranged between the burst charge and the grenade casing is formed of a plurality of film strips, which are coated with a red-phosphorus-containing incendiary composition (flares). For this purpose, the dimensions of the flares are selected such that they generate a visibility barrier in both the visible and the infrared wavelength regions.

The present invention describes a safe-and-arm device, mechanism or assembly (160) for a projectile (100,102) equipped with a second-stage propellant (124). The second-stage propellant (124) is ignited after the projectile has been ejected out from a launcher barrel. A lockpin (190), being urged by a spring (194), is responsive to ignition of the second-stage propellant; after the lockpin (190) and spring (194) sense and respond to the second propulsion, an unbalanced rotor (164) forming part of the safe-and-arm device or assembly (160), is released to rotate from a safe state to an armed state, as the projectile continues traveling along its trajectory to a target. In one embodiment, the projectile is configured with a 40 mm cartridge containing a first propellant (122). An impact sensor may trigger an electric detonator or a point detonator may trigger a stab detonator to set off explosives disposed in the projectile.

An inertial mechanism including an activating mechanism and a time delay mechanism coupled to the activating mechanism for delaying a time in which the activating mechanism is activated after a predetermined acceleration profile occurs. Where a coupling of the time delay mechanism with the activating mechanism to activate the activating mechanism initially moves away from the coupling when the predetermined acceleration profile occurs before the coupling occurs after a time delay.

An inertial mechanism including a member rotatable about an axis between activatable and activated positions, in the activatable position a first center of mass of the member is offset from the axis in a direction perpendicular to a direction of acceleration, the member having a surface; and another member rotatable about an axis between rest and activated positions, the rest position being where the second member cannot be moved into its activated position from an acceleration event, the other member also having a surface, the surfaces engage with each other when the member moves to its activated position to move the other member from its rest position to its activatable position, which is also where a center of mass of the other member is offset from its axis in the direction perpendicular to the direction of the acceleration.
