In order to increase the firepower of infantry detachments, the world's army powers are trying to show their talents: the Americans use automatic rifles and "Garand", the Germans use general-purpose machine guns, and the Soviet Union has AK47s and rocket launchers. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The infantry of various armies is indispensable to light mortars, and small Japan likes to use grenadiers, but whether it is 50 or 60 mm mortars, grenadiers or rocket launchers, they all have a common "shortcoming": they occupy the staffing and need to be used by special personnel in most cases, and they generally cannot be played without long-term professional training.

Infantry not only needs direct fire weapons when attacking fortifications, but also curved firepower, because direct fire is not omnipotent. Even the Red Army, which had an overwhelming artillery superiority in the attack on Berlin at the end of World War II, needed close-range curling fire support.

The simplest and most common form of warp fire support is probably a grenade, but it has several drawbacks: it has a limited throw distance, and it is difficult to throw from low to high.

This rocket grenade designed by Laskloff was designed to solve the problem that ordinary grenades are difficult to throw from low to high: although Laskloff was originally a member of the fortress troops, he had been in the army for many years and was familiar with the characteristics of the equipment.

He learned that when the target was high in a mountainous and hilly area, it was difficult for direct fire to be effective, especially at a distance where a grenade could be thrown.

"Marshal, it is difficult for our wooden-handled grenades to be thrown to high places by manpower, and sometimes the grenade fuse will be delayed due to the fire, and the thrown grenades will roll down the slope to injure our own native soldiers, and the enemy may also throw the unexploded grenades back. The problem of the new oval grenade is more prominent, and I thought of this solution. ”

Apparently Raslov didn't think much of it: the wooden-handled grenade was designed by the deputy commander-in-chief!

"Straight lines." Lin Jun smiled in his heart, but such a person likes it himself: but it's a bit sad, there is a small reason why he designed a wooden-handled grenade by himself is that it is not easy to roll down the hillside compared to an oval grenade, but it is still ......

"This solution" is the rocket grenade in front of you, "directly equip the wooden-handled grenade with a small rocket engine, and design it into a full-weapon-type rocket grenade with little difference in quality and more powerful than the wooden-handled grenade, so that the infantry will have a medium-light and flexible trade-off throwing weapon, and the combat distance can also be close or far." ”

"You used the rocket engine principle of the bazooka, right?" Lin Jun played with the slightly rough workmanship "stick" in his hand and said.

Yes, marshal. This 45mm rocket grenade can be thrown and launched by hand, and does not rely on other equipment and equipment, and can be launched in a standing, kneeling and lying position; It is easy to operate, the mass of the whole bomb is less than 0.7 kg, and the length of the bomb is 210 mm; The firing range can reach up to 400 meters, and the lethality power is slightly greater than that of our wooden-handled grenades, because there is no blind zone in the rear of the unit; The structure is also quite simple, there are not many parts, and the material process is also ordinary. ”

Why there is no blind spot Lin Jun understands: in his previous life, he also had a 77-1 grenade grenade with an iron handle as a toy, which was designed to eliminate the blind spot of the wooden handle.

Lasslov took the grenade in Lin Jun's hand and continued: "I designed a simple aiming device for it, which can be roughly aimed; There is basically no recoil when launching, and the sound is small, which is suitable for use in narrow urban spaces and mountainous and forest environments, and can deal with exposed and hidden enemies; Anti-tank grenades can also be made into clusters as needed......"

After the introduction and physical explanation, Lin Jun quickly understood the structure and characteristics of this new weapon: the rocket grenade is composed of three parts: the grenade warhead, the launch canister and the aiming cover.

The grenade warhead is composed of a fire element, a projectile body, a rocket engine, etc., and the warhead shell is ovoid to improve the directionality of fragment scattering. In order to make the fragments uniform and increase the lethal power, the warhead consists of the upper and lower shells pressed with prefabricated notches and the ******* explosives inside: if the process is to be simplified for mass production, the preset notches can be omitted, and the warhead casing can also use the current molds and processes for the production of oval ordinary grenades.

The grenade launcher also has the function of holding a handle, which is equipped with a flame extinguishing cover, firing button, joystick, firing machine and other parts. When carrying on duty, the fuse and engine parts connected to the rear of the grenade warhead are inserted into the launch canister, and the aiming cover is sleeved on the outside of the launch canister, becoming a whole piece like a grenade.

When thrown by hand, the rocket grenade can be thrown at the target as a whole; When firing with a canister, the aiming cover with a connector is unscrewed from the rear of the canister and fixed in the card slot on the side wall of the canister, and the shooter holds the canister and aims at the target through the sight behind the aiming cover.

After pulling the firing button, the rocket engine delivers the grenade warhead to the target area.

The canister is single-use and discarded after use.

Because of the "dual-use", it is equipped with two sets of firing parts: when thrown by hand, the warhead is used to pull the firing parts; When firing from a canister, use a bottom-fire firing element.

"The structure of the triggering part of this grenade is similar to that of a wooden-handled grenade, but the location of the two is different." Lasslov took it and said: "You see, its pull-fire is located in the nose of the warhead, and the pull-fire of our wooden-handled grenades is located in the wooden handle at the rear of the warhead. If it is thrown, you must first unscrew the protective cap of the ignition part at the front end of the grenade, pull out the fire rope hard, and rub the copper wire spring to rub the fire cap to ignite the gunpowder, and after a delay of about 3-4 seconds, it will detonate the **** at the end of the detonator, and the **** detonates the explosive to make the grenade explode. ”

The warrant officer was probably used to it, as careful and serious as he was teaching recruits in the army, and Lin Jun did not interfere with his explanation.

"If you fire from a canister, use a bottom-fire firing element. After the firing button is pulled, the striking plate strikes the tail of the firing pin, the head of the firing pin hits the fire cap and ignites, the fire cap ignites the transfer of gunpowder, and the transfer of gunpowder ignites the ****** in the rocket engine, and the gunpowder gas produced by ****** combustion is sprayed out from the nozzle hole at the tail of the rocket engine, pushing the rocket grenade warhead to fly away from the launch canister. ”

Between the grenade warhead and the rocket engine, there is a bottom inertial activation fuse, which is composed of three major mechanisms: firing, centrifugal safety, and detonation, and an anti-reset device.

The firing mechanism is composed of a firing pin and a firing pin, etc.; The centrifugal safety mechanism is composed of three spring centrifugal pins with radially symmetrical configuration; The detonation mechanism is composed of a detonator shell, a charge column, etc.; In addition to playing the role of insurance, the safety spring of the anti-reset device also prevents the freed centrifugal pin from resetting together with the sliding sleeve.

The centrifugal safety mechanism is usually jammed by 3 symmetrically configured spring centrifugal pins to prevent it from moving forward, so that it cannot fire **** and fire. Even if the centrifugal force generated by the accidental rolling of the rocket grenade during the duty state, the centrifugal pin of the spring cannot be moved outward and the firing pin can be released, so as to ensure that the inertial triggering fuse at the bottom of the bomb is in a safe state.

When the rocket grenade is ignited when launched, when the grenade is driven by gunpowder gas and flies in the air, the speed gradually increases, and when it increases to a certain speed, the centrifugal pin overcomes the resistance of the centrifugal spring under the action of centrifugal force and moves outward, and the sliding sleeve moves down to block the centrifugal pin hole under the action of the safety spring, so that the centrifugal pin can not be reset, so that the firing pin is released from the insurance, and the firing mechanism is in a state of readiness.

When the grenade warhead is in the air, if the rocket engine stalls for some reason, or the engine does not work properly, the rotational speed will be extremely small, and the centrifugal force will not move the centrifugal pin outward to release the firing pin, and the fuse will still be in a safe state.

When the grenade hits the ground, due to a sharp deceleration, the firing pin overcomes the resistance of the safety spring and moves forward by inertia to fire ****, detonating the explosive through the detonation mechanism!

It's simple, but it's like an ultra-small bazooka, with all the necessary organs: the launch canister consists of a flame extinguishing cover, a barrel, a firing button, a joystick, a firing mechanism, etc.

The effect of installing a flame extinguishing cover is mainly to reduce the impact of the gunpowder gas ejected by the engine of the rocket grenade at the moment when it flies away from the launch canister on the shooter, the outside of the cylinder is engraved with a reference line, which is used for the distance division on the connector, and the inside of the cylinder is provided with the joystick and the firing mechanism connected with the firing button.

The aiming cover with connector serves two purposes: first, it is used for simple aiming when it is combined in the card slot on the side wall of the launch canister; Second, when it is not removed from the rear of the launch barrel, the screw rod at the bottom of the connector is screwed with the firing pin seat, so that the service insurance steel ball is pressed in the firing pin groove, and the firing pin cannot move forward, and the whole bullet is in an insurance state, so as to ensure the safety of the service.

There are two semi-circular card slots on the front side of the canister for the connector inside the sight cover for rough aiming.

The front of the connector is engraved with a distance reticle, the long line represents the shooting distance lOOm, 200m, 300m, and 400m, and the distance between the short line and the adjacent long line is divided into 50m.

The rear of the aiming cover is provided with a front microhole, a rear microhole, and a vision window, and the shooter's eyes are close to the front microhole, and through the vision window, the target is set into the center of the rear microhole to shoot.

In addition, in order to ensure that the grenade warhead will not slip out of the aiming cover during the hand-projection or transportation, a fixed spring plate is provided in the aiming cover, and the fixed spring plate is usually stuck in the stop groove of the launch canister to play the role of fixing the bullet.

When this rocket grenade is fired from a canister, the shooter needs to hold the warhead and the flame extinguishing cover with his left hand to prevent the relative displacement and rotation of the two, and the right hand first rotates the aiming cover by 15 to 30 degrees to make the spring blade exit the canister stop groove. Pull the aiming cover back again so that the aiming cover retreats to the back of the connector, and then rotate the connector again until the connector detaches from the rocket grenade.

Pinch the head of the connector slightly flat and insert it into the semicircular card slot of the launch canister, at this time the shooter should also pay attention to the connector must be in place, so as not to affect the shooting effect.

According to the firing distance, the corresponding distance reticle is aligned with the reference line on the launch canister, and the firing button is moved vertically down to exit the second safety (arc slot) and then rotate the firing button, so that the firing button and the simplified body are in a 90 firing state. Then aim according to the correct posture, after aiming at the target, pull the firing button backward to release the joystick to the striking plate, which rotates 120 under the action of the torsion spring, striking the firing pin, so that the rocket grenade warhead is launched.

There is no need to remove the aiming cover when throwing, just unscrew the protective cap of the fire part of the hand throw, take out the rope, and pull the rope hard to throw it at the target.

After listening to the specific introduction, Lin Jun began to hear the operation steps a little big, not to mention the functions of a large number of parts: "Raslov, you said this, this ordinary soldier must go through very systematic training to use it proficiently, otherwise it will be difficult to use." ”

It's really a coincidence, the terrible scar on the face of Laslov, who has been "expressionless" at this time, jumped, and the few guards of Landscoczy, who were standing beside Lin Jun, suddenly stared at Laslov, which could be regarded as a conditioned reflex.

Feeling the momentum of his guards that burst out in an instant, Lin Jun raised his hand slightly, "Lasslov, you usually have to prevent your face from getting cold, and it is easy to cause follow-up problems after the facial nerve is injured." ”

"Thank you, Marshal. Your wife is the best surgeon, Comrade Vuginskaya has seen my wounds, and if it were not for Comrade General, I would have had a problem even speaking. ”

"Is it convalescence?"

"Yes, Marshal."

Lasslov was not embarrassed because Lin Jun criticized his design as somewhat unreasonable, his face twitched involuntarily, and he couldn't control it at all.

Just now, the people in the factory on the side were shocked, and the comrades of the factory director felt that their hearts were about to jump out, and they couldn't even say anything to explain!

The comrades in the factory knew that Comrade Warrant Officer's face had been expressionless because he could not make expressions at all, and his facial nerves were damaged; Sometimes he will twitch unconsciously, which is very scary to look at, and will make people think that the lieutenant has a big psychological fluctuation in his heart. In fact, the warrant officer is completely uncontrollable and unconscious.

"This grenade is my first design, and the actual test found that it still has many shortcomings, such as the launch canister is a bit short, resulting in a short guide stroke of the rocket warhead, coupled with a short aiming baseline, so the shooting accuracy is poor. However, if the launch canister is lengthened, it will lead to inconvenience in carrying, which violates the original design intention; If the shooter is not handled properly, the hands and eyelids may be burned by the gunpowder gas sprayed from behind, so I had a second thought. ”

"I always tried to simplify its design, but it didn't work." Laid down that "stick".

With that, Lasklov picked up the grenade launcher that was on the table next to him.

Before Lasslov could explain, Lin Jun spoke first: "Have you ever seen a German combat pistol modified with a flare gun and equipped with a super-caliber warhead?" ”

Lasslov was a little puzzled: "No, marshal. Any questions? What kind of weapon is that? ”

"No, just casually asking."

Lin Jun didn't ask casually, but wanted to prove a question in his heart: is it really "not afraid of not being able to do it, just afraid of not being able to think of it"? Still got some inspiration.

"Combat pistols" have been around for a long time, and the combat pistols with super-caliber warheads used by the German infantry have been captured in small quantities in the final stages of the Minsk operation, but it is unlikely that Raslov saw it: the Germans had not used that strange weapon during the defense of the Brest fortress.

If you talk about 23mm combat pistols alone, then it is possible that Raslov has seen it; However, even if there is a seizure, the warrant officer of the ordnance generally does not notice the ordinary-looking "flare gun".

It seems to be a coincidence.

The combat pistol equipped with a super-caliber warhead used by the German infantry is a relatively distinctive anti-armor and anti-infantry curved fire weapon developed by the German military industry at present. From a historical point of view, it has similarities and differences with the concept of "gun grenade", and is closer to the category of "grenade launcher".

"Gun grenades" are generally fired on combat rifles with empty cartridges, while this "combat pistol" and its ammunition are dedicated and "synthetic", and have a "firing function" in themselves.

And as far as Lin Jun knows, they are generally regarded as the ancestors of "grenade launchers" in the world.

As early as 1928, the German army was equipped with a 1.3-kilogram flare gun designed by the Walter Company, of course, the gun could only fire flares, but a single-function flare gun, and its function was the same as that of its "counterparts" in the armies of other countries in the world, nothing special.

The German flare gun was reloaded, and later modifications used light metal, reducing the overall weight to 0.78 kg, and could be used as a special pistol.

Because the modified gun had a barrel with an inner diameter of 23 mm and five rifling wires embedded in the barrel of the base gun, the originally single-purpose flare gun became a combat pistol.

Both guns had a simple sighting device, the angle of fire was determined by a simple gauge and the dimensions were similar, with a total length of 24.5 cm and a barrel length of 15.5 cm.

In addition to flares, the bullets used for combat pistols originally included flare grenades: the bullets were 12.5 cm long and contained 30 grams of explosives, which could be used as grenades, but their lethal effect on people and other targets was extremely limited.

However, soon the German military industry developed a new type of ammunition for combat pistols, which was actually based on the grenade body and added an insertion rod that matched the caliber of the combat pistol, which was called a projectile.

The original model of this type was the Wurfkoerper 358 LP, which was warheaded by a long-handled grenade ("potato pestle"), but it was so heavy that it affected the range.

The next model was the Wurfkoerper 361 LP, which was distinguished by an oval grenade in the nose of the guide bar. This projectile is much more practical than the Wurfkoerper 358 LP, but it is slightly insufficient in terms of flight stability of the warhead.

A further improvement was to change the insertion of the guide rod to a steel-clad wooden handle, which was detached after firing and stabilized by a steel sleeve at the tail. As a result, the flight stability of the warhead of the Wurfkoerper 361 LP was greatly improved (between 1941 and 1942, a total of 261,788 Wurfkoerper 361 LPs were produced. ）。

In Minsk, the Germans airdropped some of these weapons to help improve the ability of the besieged Germans to fight in the streets, but none of them could change the fate of the besieged troops.

However, the German combat pistol attracted the attention of the Red Army, but it was classified as a kind of "strange grenade", which the Soviet Union itself was developing, so it did not attract much attention at the front and the armament department of the Red Army.

The German Wurfkoerper 361 LP weighed 0.325 kg, had a total length of 22.4 cm, a muzzle velocity of 40 / s, and a maximum range of 85 meters. Later, the total length of the plastic guide rod was reduced to 21.8 cm, and the maximum firing range was increased to about 100 meters.

In addition to grenades, as the war progressed, several anti-armor munitions were developed for combat pistols: the first anti-tank projectile was the 326-LP projectile blaster (Wurfgranatpatrone 326 LP), abbreviated as WK 326 LP.

The structure of the missile is relatively complex, the tail has four stable tails, its muzzle velocity is 72 m / s, and the maximum range can reach 400 meters, but the warhead charge is only 12 grams, and the actual anti-armor capability is quite limited.

The WK 326 HL/LP (HL=Hohlladung, hollow charge) is slightly better in anti-armor capabilities, and its tail structure is similar to that of the WK 326 LP, but the warhead weight is increased to 180 grams. Using hollow charge technology, it contains 22 grams of ****** explosives, which can penetrate 50 mm thick armor, has a muzzle velocity of 60 m/s, and a maximum range of 300 meters.

Between 1941 and 1942, 402,395 WK 326 LP and WK 326 HL/LP were produced. This weapon had also been captured by the Red Army, but Lin Jun didn't know about it - no one thought it would be important enough to be reported to the deputy commander-in-chief.

Because the accuracy of those grenades at a distance of about 300 meters was really unsatisfactory, the combat pistol was considered an ineffective anti-tank weapon in the German army, but the hollow charge warhead of the WK 326 HL/LP bullet can really penetrate 50 mm thick armor, so the German military industry is still equipping the hollow charge warhead with a variety of tails.

Under this guiding ideology, as far as Lin Jun knows, the Type 42-LP anti-armor projectile (Panzerwurfkoerper 42 LP) also appeared later.

The projectile had a hollow-charge warhead with 60 grams of explosives and could penetrate 80 mm thick steel armor.

In order to launch this heavier warhead up to 75 meters away, the bomb uses more ****** and correspondingly greater recoil.

Because of the increased recoil, the barrel of the combat pistol was lengthened, and a shoulder rest and foldable bipod were added. In this way, the "submachine pistol" appeared: the weapon had a total length of 58.5 cm, a barrel length of 18 cm and a total weight of 2.45 kg.

The Germans do not have a clear record of how many of the 278,845 Type 42 signal guns equipped with the troops were converted into combat pistols and submachine guns, but history is certain that 417,255 Type 42 signal guns were produced, the vast majority of which were produced at the Carl Walter Arms Factory in Zira Merris and the Elma Weapons Factory in Erfurt.

In addition to "combat pistols" and "submachine guns", Germany was armed with quite a few genuine grenades, and not such strange weapons as "combat pistols".

The purpose is the same as in other countries: a grenade is an infantry small explosive weapon that fills the range of a grenade and a mortar, and infantrymen armed with a grenade launcher fires a super-caliber grenade through a grenade launcher mounted at the muzzle of their rifle.

The German grenade launcher of World War II was mounted on the 98K, Gewehr 43 rifle, StGw 44 assault rifle and FG42 paratrooper rifle.

The main structure of the German grenade launcher was a short rifled firing tube with a caliber of 30 mm and a length of 25 cm, weighing about 0.75 kg, which was mounted at the muzzle of the rifle. Its complex sighting device is mounted on the left side of the barrel, near the rifle sight, and has a gauge range of 300 meters.

German production of grenade launchers during the war continued until May 1944, with a total of 10,450,014 units produced.

There were two main types of grenades distributed to the German front: grenades and hollow-charge anti-armor grenades. The grenade is mainly equipped with AZ 5071 bump fuze, incendiary fuse and delay fuse, and is used to kill living targets in bunkers, foxholes, houses and fortifications.

The maximum range of the grenade is about 280 meters, and when the horizon allows, it can also reach 310 meters. The grenade warhead weighs 288 grams and is loaded with 31 grams of explosives, which is detonated by a bump fuse. When using a delay fuze, the delay time is 6.5 seconds.

The long-range grenade uses the AZ 5071 bump fuse and incendiary fuse, and the range can reach 500 meters, while the ****** must also be increased by 50 percent to 1.5 grams, and the lethality of the warhead remains the same.

In addition to the general anti-personnel grenades, the Germans also had hollow-charge anti-armor grenades, such as the first model was the Type 30 anti-armor grenade: it weighed 245 grams and the ****** weighed 1.1 grams.

But its design was unsuccessful and its ability to penetrate armor was limited, so it was not mass-produced.

Its successor was the Type 40 anti-armor grenade, which was more powerful, with a total length of 18.5 centimeters, a weight of 390 grams, a warhead containing 115 grams of explosives, a ****** weight of 1.9 grams, and a 60-degree hit angle that could penetrate 80 mm of armor.

However, the accuracy of such projectiles was also reduced by the increase in range, and the trained shooter had a determined hit distance of 100 meters for fixed targets and 75 meters for active targets. The grenade shooter must hold the rifle steady when firing, as the rotationally stabilized grenade creates a large reverse moment when exiting the muzzle.

A total of 23,800,08,900 anti-armor grenades were produced by the Germans, and 18,273,600 were used during the war.

Raslov is also familiar with the grenade, because the Red Army also has it, which also makes the warrant officer familiar with its shortcomings: for example, it is troublesome to fire, and it is necessary to use special empty cartridges, which leads to constant problems in logistics and firing.

If you accidentally fire a grenade with live ammunition in real combat, the consequences can be catastrophic! Grenades that can be fired with live ammunition are not yet available.

It was for this reason that Raslov thought of another way: instead of firing empty cartridges, he simply used a new ammunition and developed a completely new grenade weapon.

Lin Jun held the heavy grenade launcher in his hand, and did not ask how to solve the ammunition problem perfectly (it is still being improved), but said: "Raslov, I have a suggestion for you: simply sawn off this wooden tray and use a simple connector to snap it to the assault rifle, so that it will not occupy the establishment." ”

The words of the deputy commander-in-chief were like a thunderbolt to Raslov at this time - "Why didn't you think of it?!" ”

One of the original design concepts of providing a new infantry light curved support weapon was to not take up staffing, but Lasslov's thinking clearly entered the realm of traditional support weapons - dedicated support to the infantry, not infantry to support themselves!

At this time, a veritable concept of "infantry squad cannon" matured in Raslov's mind. (To be continued, if you want to know what will happen next, please log in to the www.qidian.com, more chapters, support the author, support genuine reading!) (To be continued.) )
