7results about "Mechanical fuzes" patented technology

The technology subject of the present application generally concerns an aerial munition unit comprising a proximity fuze functionality and an impact fuze functionality, selectable by a crew member of an aircraft bearing the munition, after the aircraft has taken off and prior to munition release, to render active or operable the proximity fuze functionality or the impact fuze functionality.

The present invention relates to a fire-fighting device, which comprises: - a casing (2) which delimits an internal cavity (3) in which is placed at least one dispersible extinguishing agent (4), and - pyrotechnic means (5) adapted to generate an explosion causing a rupture of said casing (2) and a dispersion of said extinguishing agent (4), which pyrotechnic means (5) comprise: - at least one explosive charge (6), generating said explosion, and - detonating means (7) intended to trigger said explosion of said at least one explosive charge (6), And said detonating means (7) comprise: - an ignition device (8) designed to trigger, in an active state, said explosion of said at least one explosive charge (6), and - a shock sensor (9) designed to detect a mechanical shock received by said device (1) and to bring said ignition device (8) into said active state upon detection of said mechanical shock.

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.

A hand-throwable effect-producing body with a manually graspable housing body, a manually operable triggering device having a spring-loaded impact body, an ignition device initiatable by the triggering device and comprises an ignition charge, a delay device is initiatable by the ignition device and comprises a delay charge and a delay line, and a main charge configured to be initiated directly or indirectly by the delay charge. The impact body is configured to be manually moved along the longitudinal axis thereof counter to a spring force into a preloaded position and to be releasably arrested there and to be released by manually operating a triggering element of the triggering device, such that it can shoot out of its preloaded position along the longitudinal axis against an axial stop and thereby initiate the ignition charge.
