A projectile fuze () having fuze electronics in which the time of flight (T) can be programmed, having a timer/counter which counts up to the programmed time of flight (T)&#x2014;minus a defined time value (&#x394;t)&#x2014;and then charges an electrical firing circuit, and having a mechanical safety and arming unit () which switches a firing chain to the armed position after a specific time interval. The firing chain has an electrical detonator (), a fuze needle (), a piercing detonator () and a booster charge (). The projectile fuze () has a pyrotechnic force element (), which is interconnected with the fuze electronics and mechanically blocks the safety and arming unit () until the time of flight (T) minus the predetermined time value (&#x394;t) is reached, after which the electrical firing circuit is charged and the safety and arming unit () is unlocked to the armed position by initiation of the force element ().

Projectile fuze with fuze electronics including a timer/counter

A mortar includes a fuse device having a detonator, and a firing booster arranged to be ignited in response to detonation of the detonator. The detonator is detonated by a firing pin. Advancement of the firing pin toward the detonator is effected by an electrically ignitable pyrotechnic charge.

Fuse device for a projectile

A mortar fuse includes a fan wheel rotated in response to motion of the mortar fuse after the mortar has been launched. The fan wheel rotates a helix on which an activation wheel is mounted. The activation wheel moves in a path along the axis of the helix in response to rotation of the helix and eventually impacts against, and pierces, an acid container. Battery acid flows from the container and into battery cells, to energize the battery. The activation wheel includes a magnetic material. A coil is disposed along the path of travel of the activation wheel so that electric energy is generated in the coil as the magnetic activation wheel moves therepast. The electric energy operates a counter which controls a time function of the mortar fuse.

A fuse device for a mortar shell includes an impact weight carrying a detonation charge and arranged to impact against a firing pin when the mortar shell strikes a target. A safety arm locks the impact weight against movement toward the firing pin in a safety position. The safety arm is movable out of locking relationship with the impact arm to establish an armed condition of the fuse device. Energy for moving the safety arm is stored in a spring. That energy is stored after the mortar shell has been launched, because an impeller is rotated by an air flow generated by the moving mortar shell, and that impeller rotation is transmitted to the spring to store energy.

Objects are detonated by placing charges adjacent respective ones of the objects and connecting the charges to a time fuse by means of respective explosive cords for detonating all of the charges simultaneously when the time fuse fires. The time fuse can be set by fitting a clock to the time fuse. The clock has separate timer mechanisms which can be wound-up simultaneously and which prevent the clock from being fitted to the time fuse if the timer mechanisms have run down asynchronously. An adapter can be attached to the time fuse for releasing a safety of the time fuse upon receiving a remote signal such as an encoded radio signal.

Apparatus for detonating a plurality of objects

A fuse for low-spin or non-spin projectiles comprises a detonator-carrying rotor movable to a live position. The rotor is released for movement in response to firing recoil. Movement of the rotor is effected by a spring which is relaxed prior to recoil firing and is energized in response to firing recoil.
