Cartridge-case-free bullet

Abstract

The invention discloses a cartridge-case-free bullet. The bullet comprises a bullet body which comprises a bullet head and an outer protective shell, the outer protective shell is coaxially arranged at the rear end of the bullet head, a power nozzle is formed in the rear end of the outer protective shell, a volute inner conical spiral flow guide channel is formed in the outer protective shell, a cavity between the volute inner conical spiral flow guide channel and the outer protective shell is filled with spraying gunpowder, a plurality of first gunpowder pressure nozzles are arranged in the volute inner conical spiral flow guide channel, the power nozzles are connected with an electronic switch device, and the electronic switch device is electrically connected with the spraying gunpowder. According to the bullet without the cartridge case, the speed of an original bullet is broken through, the firing range precision is improved, and recoil force is avoided; the conical spiral flow guide channel in the volute is high in speed, large in thrust and high in bullet rotating shooting precision under gunpowder detonation acting.

Description

technical field [0001] The invention relates to the technical field of weapons and ammunition, and more specifically, the invention relates to a bullet without a casing. Background technique [0002] At present, the various types of bullets and projectile warheads used are divided into three types according to the state after contact: solid type, which has strong penetrating force, but relatively poor blocking force; expansion type, which has not very strong penetrating force, but good blocking force , most of the kinetic energy can be transmitted to the target in a very short time; the crushing type, the warhead will shatter after hitting the target, and transmit all the kinetic energy to the target in an instant, the penetrating force is very weak, but the blocking force is very strong powerful. Regardless of the type of warhead, there are still deficiencies in the accuracy of hitting the target and improving the effective range. The warhead moves in a spiral motion in th...

Problems solved by technology

[0002] At present, the various types of bullets and projectile warheads used are divided into three types according to the state after contact: solid type, which has strong penetrating force, but relatively poor blocking force; expansion type, which has not very strong penetrating force, but good blocking force , most of the kinetic energy can be transmitted to the target in a very short time; the crushing type, the warhead will shatter after hitting the target, and transmit all the kinetic energy to the target in an instant, the penetrating force is very weak, but the blocking force is very strong powerful

Regardless of the type of warhead, there are still deficiencies in the accuracy of hitting the target and improving the effective range. The warhead moves in a spiral motion in the gun bore and gun bore. A certain rotation speed, causing target accuracy and effective range to be affected
