Abstract
The invention provides a 130 mm PL59A type base bleed and rocket composite range-enhanced high explosive projectile of a howitzer, which can fire important deep targets (such as headquarters, staging areas, traffic hubs and the like) of enemies, provide remote fire support for ground combat troops and carry out remote ground fire suppression on ground forces of the enemies under a situation of not changing a firing position because a firing range of the 130 mm PL59A type base bleed and rocket composite range-enhanced high explosive projectile is far larger than the firing range of a base bleed range-enhanced projectile. Aiming at a variation rule of a projectile flying resistance, the projectile is a novel range-enhanced way of comprehensively using two range-enhancing technologies of base bleed resistance reduction and rocket boosting on the basis of the base bleed range-enhanced projectile. The advantages of the two range-enhancing technologies can be sufficiently exerted through using a range-enhancing mode of using a base bleed first and then using a rocket. The range-enhancing rate can reach more than 50% while the composite range enhancement is combined with a high initial speed and low resistance projectile shape technology. At present, because common cartridges of domestic howitzers with apertures of 130 mm are common grenades and base bleed range-enhanced projectiles, the development of the 130 mm PL59A type composite range-enhanced projectile fills up the blank of domestic technology so that the firing ranges of the howitzers with apertures of 130 mm are largely increased and the fighting efficiency is increased.
Description
Affiliated technical field
In modern war and national defence defended war, common howitzer and base bleed range expansion howitzer are because of the short needs that can not satisfy some combat duty of range.The composite distance increasing bullet because of far firing range much larger than the base bleed range expansion bullet, enemy's depth important goal (headquarter, area of assembly, transport hub) waited shoots and ground combat troop is carried out long-range fire support and enemy ground forces carried out remote ground firepower suppress.
Background technology
This bullet is on the basis of base bleed range expansion bullet, at the Changing Pattern of projectile flight resistance, and the novel journey approach that increases of row's drag reduction and two range-extending techniques of rocket assist at the bottom of the integrated application.Adopt the journey mode that increases of elder generation's end row back rocket can give full play to the advantage of these two kinds of range-extending techniques and avoid its shortcoming.
Summary of the invention
After this bullet bullet was launched medicine release gun muzzle and lights end row, the end, arranged beginning work.When bullet entered certain altitude, rocket engine was lighted in the time of end row work, when entering the little high-altitude of atmospheric density like this, quickened with rocket engine, to obtain the higher journey rate that increases again.Fill up domestic blank, the range of 130 millimeters bore howitzers is increased greatly, improved fighting efficiency.Its detailed structure (see figure 1).
Structure
Tandem composite distance increasing system at the bottom of this bullet employing bullet.Mainly form by fuse, warhead, rocket portion, end row portion and ignition system.
1, fuse
Fuse is a DRL12A machinery contact fuze.
2, warhead
Filling TNT in the warhead.
3, rocket portion
Rocket means is made up of parts such as rocket powder column, preceding igniter cartridge, jet pipes.The rocket powder column is a modification double-basis type rocket medicine.
4, end row portion
Bottom row device is made up of end row's object and bottom drainage drug post.The bottom drainage drug post adopts the firework medicament prescription of technology maturation, and burn rate is stable, and drag reduction efficiency is higher.
5, ignition system
The rocket firing system adopts the Dark Ignition tool.
The primary structure characteristics
Major technique
Tandem at the bottom of the bullet extended-range device total arrangement employing bullet:
Series-mode frame is exist together bullet bottom of rocket means and bottom row device at the bottom of the bullet, and bullet relatively, rocket means be preceding, bottom row device after, be series system and arrange.At the bottom of the bullet, the propagation of explosion sequence with bullet does not interfere, and makes whole bullet general structure layout simple relatively because rocket means and bottom row device are lived together.According to the design and the arrangement of rocket exhaust passage, this citation form can be realized asynchronous working, and the reliable operation degree is higher, plays to increase Cheng Zuoyong.
Row's rocket composite distance increasing kills quick-fried bullet beneficial effect and is at the bottom of 130 millimeters howitzers of PL59A formula:
1, the composite distance increasing bullet because of far firing range much larger than the base bleed range expansion bullet, can be under the situation that not change the shooting position, enemy's depth important goal (headquarter, area of assembly, transport hub) waited shoot and ground combat troop is carried out long-range fire support and enemy ground forces carried out remote ground firepower suppress.
2, this bullet is packed into, and 122 millimeters big guns are interior pulls the trigger, and carries out increasing the first time journey by bottom row device earlier, is finished by rocket engine more for the second time to increase journey, and two parts act on respectively playing and increase the effect (see figure 2) that journey hits the mark for twice.
Description of drawings
Fig. 1 is that row's rocket composite distance increasing kills quick-fried bullet structural representation at the bottom of 130 millimeters howitzers of PL59A formula
Earlier TNT is filled in warhead (2) enclosure interior, rocket engine (3) is filled in motor body inside.The bottom drainage drug post (4) that will suppress and coat again is assemblied in end row's enclosure interior.At last with warhead, rocket engine and bottom row device three part combinations.Screw on fuse (1) at last.
Fig. 2 is that row's rocket composite distance increasing kills quick-fried bullet working state schematic representation at the bottom of 130 millimeters howitzers of PL59A formula
Bullet is after the propellant powder effect goes out gun muzzle, bottom row device (4) is started working, when bullet enters certain altitude, end row's end-of-job, rocket engine (3) is lighted, push bullet to apex of the trajectory after, bullet freedom of entry trajectory, hit the mark and ignite warhead (2), reach the purpose of annihilating target by fuse (1).
The specific embodiment
Can find out from Fig. 1 and Fig. 2, earlier TNT be filled in explosive assembly casing inside, rocket engine is filled in motor body inside.Bottom drainage drug post that will suppress and coat and ignition system are assemblied in end row's enclosure interior again.At last with warhead, rocket engine and bottom row device three part combinations.The interior percussion of the 122 millimeters big guns of packing into carries out increasing the first time journey by bottom row device earlier, is finished by rocket engine more for the second time to increase journey, and two parts act on respectively playing and increase the effect that journey hits the mark for twice.
Claims (2)
1. series-mode frame is exist together bullet bottom of rocket means and bottom row device at the bottom of this bullet bullet, and bullet relatively, rocket means be preceding, bottom row device after, be series system and arrange.At the bottom of the bullet, the propagation of explosion sequence with bullet does not interfere, and makes whole bullet general structure layout simple relatively because rocket means and bottom row device are lived together.
2. according to described its main feature of claim 1 be: adopt the base bleed drag reduction to increase journey.When bullet enters the little high-altitude of atmospheric density, quicken with rocket engine again, to obtain the higher journey rate that increases.
