An inertial delay mechanism for use in an explosive projectile is provided. The delay mechanism consists of an inertial delay fuse that is precise, doesn't require sensitive primary explosives and doesn't utilize electronic circuitry. The inertial delay fuse includes a free sliding charge element that strikes an anvil located opposite to the sliding charge element. A delay gap is provided between the sliding charge element and the anvil. Upon impact, the sliding charge element slides forward and impacts the anvil, thereby inducing a shock wave in an initiator charge that subsequently results in detonation of main charges. The design is mechanically simple and robust enough to withstand severe g-loading forces that occur during firing and penetration of a projectile.

An impact switch includes a housing having a wall including at least two electrically conductive contact elements spaced apart from one another. The switch includes an inertial body having a conductive surface disposed in a tapered aperture and electrically connecting the contact elements to one another in a switch closed condition. An impact switch for rapidly firing an explosive device is provided.

A toy hand grenade has a plurality of bores which receive soft darts. A launcher is received in each bore and is spring loaded. An actuator retains the launchers in a spring-loaded, unactuated position. The actuator is displaceable relative to the body to release the launchers and substantially concurrently eject the darts from the hand grenade. A pin or a clip may be employed to lock the actuator in a locked position. A timer is employed to delay actuation of the actuator to release the launchers and eject the darts from the hand grenade. A sandbag ring is imposed to ensure proper orientation and stability of the hand grenade for the timer actuated feature.

An omnidirectional spring mass initiator system for use in a weapon system responsive to any direction of weapon-target impact comprising a chamber of any geometric shape, said chamber having at least one opening into said chamber; a flexible support means having a secured end and another end which is operatively positioned for insertion into the chamber through said at least one opening; and an accelerometer mass-contacting means attached to said other end of the support means. The contacting means is responsive to deceleration and, when inserted into the chamber, positioned in the center, thereof, so as to be capable of contacting some portion of the inner surface of the chamber in response to the deceleration of the system caused by any direction of weapon and target impact. The entire inner surface of the chamber is coated with a contact-sensitive lining such that when the contacting means comes into contact with the contact-sensitive lining a resultant response occurs which initiates the fuse mechanism.

1,179,298. Projectile fuzes. FORGES DE ZEEBRUGGE S.A. 29 June, 1967 [28 Oct., 1966], No. 30133/67. Heading F3A. Fuze for a bomb, comprises a detonator (not shown) carried in a pivotable carrier 14, a first locking element 13 which engages the carrier in a safety position but is displaced a predetermined time after release of the bomb, and a second locking element 26 which engages the carrier in the safety position but is displaced after impact of the bomb by the glass resulting from the combustion of a delay charge 39, the carrier then being swung by a spring into a position where combustion of the remaining part of the delay charge causes firing of the detonator. The first locking element is held against axial rotation by engagement with a pin but is displaced axially by a spring when a recess in the end face 11 of a rotatable striker guide 8 is aligned with the locking element, following shearing of a pin 19 which extends into a circumferential recess in the end face. The guide 8 is rotated by a striker 4 driven through reduction gearing 3. A spring loaded pin locks the first locking element in the inactive position. The striker is formed with an inertia mass 5 and is thrown against a primer 40 upon impact of the bomb. The second locking element is displaced by combustion gases fed into a chamber 29, and is held in the inactive position by engagement of its head 31 in a capsule 33.
摘要:
A passive impact sensor for a projectile configured to explode, destroy with kinetic energy, embed or pass through an object with a closing velocity greater than 1,000 m/s. The passive impact sensor includes an energy generating system comprised of a crystalline structure that stores latent polarized electrical energy. The crystalline structure is responsive to an impact generated shock wave that propagates at least partially through the crystalline structure to consume and depolarize the crystalline structure and release at least a portion of the stored energy to generate a voltage pulse across output terminals. An onboard antenna is configured to transmit an RF pulse responsive to the voltage pulse (direct or integrated) external to the impact sensor (and projectile) before the sensor is destroyed by the shock wave. Multiple energy generating systems can be positioned either together or fore and aft and their voltage pulses summed to transmit the RF pulse. The benefits of this device include the ability to determine impact force, impact velocity, impact angle, target mass, target density, and direct or glancing impact.
