Description

Fuse timing device

Technical Field

Background

Fuzes, also known as fuse tubes, are detonating devices mounted on projectiles, bombs, mines, etc. A detonator is a control device (system) that detonates or ignites an ammunition warhead charge under predetermined conditions using target information and environmental information. The fuzes have various classification methods, and are divided into trigger fuzes, proximity fuzes, week fuzes, time fuzes, instruction fuzes, multi-selection fuzes and the like according to action modes and principles; fuses of shells, mortar shells, rocket shells, cannonballs, aviation bombs, mines, torpedoes, deepwater bombs, landmines, grenades and the like are divided according to the types of matched ammunitions; according to the parts assembled on the ammunition, the ammunition is divided into a bullet fuze, a bullet body fuze, a bullet bottom excitation detonating fuze and the like; according to the safety degree, the fuse is divided into a detonator type without explosion suppression, a fuse type without isolation fire cap and a fuse without isolation mechanism.

The time fuse is a fuse which acts according to set time after ammunition is launched, thrown and laid, and is also called as a timing fuse. The time fuses are classified into a plurality of categories, such as powder tray (gunpowder) time fuses, mechanical (clock) time fuses, chemical time fuses, electronic time fuses, and jet time fuses, according to the action principle of the timing device. An electronic time fuse is a time fuse that is clocked using an electronic timing device. The time fuse can be divided into a digital electronic time fuse and an analog electronic time fuse according to the form of a circuit. The digital electronic time fuse uses a digital timing circuit, and controls ignition by recording the pulse number of the isochronous oscillation electric pulse. The analog electronic time fuse realizes time setting by using the characteristic that current or voltage changes along time according to a certain rule, and is mainly used for ammunition such as aviation timing bombs and the like.

The time fuse is the same as other fuses, and consists of a fuse body, an ignition control system, a safety (insurance) system, an explosion/detonation sequence, energy and the like. The largest difference between the time fuze and other fuzes is mainly reflected in the ignition control system. The ignition control system of the time fuse is composed of a time setting device or a time setting memory, a timing device, an ignition device and other mechanisms.

Compared with other fuses, the electronic time fuse is likely to be interfered by electromagnetic waves, so that the timing of the electronic timing device of the electronic time fuse is failed, and the detonation time and the detonation position of the detonation device are influenced; meanwhile, due to recoil generated when the cannonball is fired, the electronic timing device is easy to vibrate, and the electronic timing device is possibly damaged.

Further, the electromagnetic wave shielding mechanism is also fixed on the damping sheet.

The system further comprises a computer and a laser range finder, wherein the laser range finder is used for detecting the distance between a target place and a launching place and sending the distance information to the computer, and the computer calculates the time of the cannonball reaching the target place according to the input distance information, the launching angle of the cannonball and the related information of the cannonball.

Furthermore, an opening is formed in one side of the fuse body, a transparent plate is arranged in the opening, and the transparent plate is used for displaying timing of the electronic timing mechanism.

The timing of the electronic timing mechanism is adjusted by the time button according to the calculation structure of the computer. After the cannonball is launched, the timing of the electronic timing mechanism is started, and when the set time is reached, the electronic timing mechanism ignites an explosion transfer sequence of the time fuse through the electric ignition head.

The beneficial effects of this technical scheme lie in: the damping mechanism can damp the electromagnetic wave shielding mechanism and the electronic timing mechanism, so that the condition of large-amplitude vibration in the launching process is prevented, and the problem that the electromagnetic wave shielding mechanism and the electronic timing mechanism are damaged is avoided. The electromagnetic wave shielding mechanism can shield the electromagnetic wave, prevent the interference of the external electromagnetic wave to the electronic timing mechanism, ensure the normal operation of the electronic timing mechanism and have the effect of explosion at the set time and position.
