An apparatus for disabling of motor vessels moving in a waterbody. An energetic (i.e. explosive), as part of a floating assembly, is brought into contact with a motorized marine vessel's propulsion unit(s) and / or steering system, referred to generally as the underwater drive unit, due to the vessel's own motion relative to a floating line. The energetic then detonates and disables the underwater drive unit, thereby halting progress of the vessel while not harming any occupants thereof.

The utility model discloses a connecting structure of an impact fuse and an unmanned aerial vehicle and the unmanned aerial vehicle with the connecting structure, and relates to the technical field of unmanned aerial vehicle military. The device comprises a fixed plate and an extension arm vertically fixed on the fixed plate, the tail end of the extension arm far away from the fixed plate is provided with a fixing structure used for installing an impact fuse, and the extension arm can extend in the length direction so that the position of the fixing structure at the tail end of the extension arm can be adjusted in the length direction of the extension arm. According to the utility model, the fixed plate and the extension arm are both plastic products, so that the product cost can be reduced, and meanwhile, the designed sleeve arm cylinder can move along the inner arm rod to realize the extension function, so that the product can be matched with civil unmanned aerial vehicles with different wingspans, and the function of high applicability is achieved.

An inertial igniter including: a base having a first projection; a striker mass rotatably connected to the base, the base having a second projection aligned with the first projection such that the first and second projections impact when rotated; a member having a first portion engaging with a second portion of the striker mass to restrict rotation of the striker mass unless the predetermined acceleration is experienced; a mass movable from a first position where an acceleration is less than the predetermined acceleration and a second position where the acceleration is greater than the predetermined acceleration, the second position permitting the first and second portions to come out of engagement; a spring biasing the movable mass in the first position; and a shear member permitting impact of the first and second projections when the predetermined acceleration is experienced and the movable mass moves to the second position.

The invention relates to a sensor system for installation in a fuse for a projectile, comprising at least one antenna element, wherein the antenna elements are arranged on a surface that is arranged at an angle α of between 85° and 95° relative to the centre line C-C of the fuse. The invention further relates to a fuse and a projectile equipped with a fuse.

Torpedo (1), wherein an explosive warhead (6) comprises three explosive components: a detonator (10) which receives an activation command; a booster explosive (11) which is detonated by the detonator (10); and a main explosive (12) which explodes following the explosion of the booster (11). When an impact with an obstacle is detected following the torpedo's entry into water and such an impact is detected at an instant is less than a limit value Tlim (T < Tlim), an inhibition circuit (27) is activated, which brings the torpedo into a safety state in which the explosive warhead is prevented from exploding.

The present invention relates to a fire extinguishing device comprising: a casing (2) delimiting an internal cavity (3) in which at least one dispersible fire extinguishing agent (4) is deposited; chemical means (5) suitable for producing an explosion that ruptures the casing (2) and disperses the fire extinguishing agent (4), the chemical means (5) comprising: at least one charge (6) that produces the explosion; and detonation means (7) intended to cause the explosion of the at least one charge (6), said detonation means (7) comprising: an ignition device (8) designed to cause the explosion of the at least one charge (6) when in an activated state; and an impact sensor (9) designed to detect a mechanical impact suffered by the device (1) and to activate the ignition device (8) upon detection of the mechanical impact.
