The guns of the Phoenix Kingdom's garrison are still the same, and the ones being trialled are machine guns.
There are many new technologies. The previous series name of "Heavy Rain" was abandoned and replaced with a more straightforward name, "Tearer".
While the artillery shells still use old materials, the 20mm Ripper has twice the kinetic energy at a distance of five thousand meters compared to the Heavy Rain II of the same caliber.
Thanks to the accumulation of processing technology and materials, and the fact that the magic gun does not need to consider the chamber pressure issue, the barrel-to-barrel ratio of this gun is larger, reaching 60 times the diameter.
The longer barrel also provides sufficient space for the denser projectile acceleration module using new technology. Its warhead exit speed has reached 2,200 meters per second. The fastest exit speed before was that of an airborne aircraft. The gun's 1050-meter static.
It can be seen from the kinetic energy equation that when the speed is doubled, the kinetic energy will increase to four times. 2200 meters per second is more than twice the speed. Why only double the kinetic energy?
Because of the distance limit, the higher the speed, the greater the air resistance ratio and the faster the deceleration.
The muzzle speed of an anti-materiel rifle is generally about 900 meters per second, and it takes more than 20 seconds to fly 5 kilometers; a small-caliber sniper bullet also takes nearly 20 seconds to fly about 3.5 kilometers. It can be known that as the flight distance of the actual bullet increases, the speed will quickly approach its own aerodynamic critical speed. In this process, the key to maintaining speed is the bullet weight.
The 20mm caliber gun has a 135-gram warhead that is nearly 4 times the weight of an anti-materiel rifle. However, the old projectiles cannot retain their enchantment after exiting the chamber, so the effect of the surface airflow stabilization module mounted on the Ripper is almost negligible. Five thousand The meter has also entered the subsonic speed range, and the effect of increasing the initial velocity has been significantly weakened here.
To be specific, the tearer's attack intensity against the enemy at a distance of 5,000 meters is approximately 5,000 joules.
The number is not big, but the effect still depends on the bomb situation.
The damage to the target's body is more affected by the nature of the body fluid. The shock wave caused by projectile braking propagates through the incompressible liquid and causes damage to the entire body.
Supersonic strikes are very powerful, but for some units without shields, because their body size and strength are not enough to brake the projectiles, there will actually be damage overflow, which is a penetrating shot.
In the subsonic flight state, with the weight of a 20mm caliber bullet and the generally more solid outer skin of the Demon Race, the actual effect will be closer to a hammer strike. Even if the skin is not broken, the kinetic energy of 5000 Joules is enough to knock away a human-sized target. And caused internal injuries.
The little devil is not included in the calculation, because based on actual combat experience and subsequent calculations, the final contact kinetic energy of the 15mm bullet is about 3600 joules, and it will be broken by hitting the center line. However, the 4000 Joule kinetic energy line of the 15mm bullet is 900 meters away, and there is no need to guard against it at a distance of 5000 meters.
Having said that, most types of magic shields can easily block a single kinetic energy strike of 5,000 joules, but at a distance of 5,000 meters, it is unlikely to achieve continuous hits, so the current performance of the Ripper is still far away. Far from reaching the default value.
Without the cooperation of new projectiles, the main threat area of the Ripper is still limited to 2,500 meters. Within this range, the target can be forced to break through the shield and kill it by increasing the amount of bombs dropped.
There is already a clue to the development of new projectiles, but there are certain difficulties in aerodynamic appearance and process, which will take time.
Compared with the old projectiles, it is actually the difference between solid bullets and core-covered bullets.
The old-style projectiles are directly cold-cut and cold-rolled with steel bars, and the drain is repaired.
In order for the new projectile to maintain the solidification surface airflow for at least one second after exiting the chamber, a certain amount of one of aluminum alloys and lead alloys needs to be implanted in the projectile.
Lead's magic affinity is average, but it has many applications and is relatively mature. Many magic puppets are based on it.
The lead bullet core was eliminated during the demonstration stage, mainly because its texture was too poor, and the lead alloy with a large lead content was not good either. In the supersonic flight state, it was too soft and would deform the projectile body. Other directions create unnecessary pressure.
From an industrial perspective, lead is banned in many industries in the Kingdom. It is mainly used in glass and battery manufacturing, and the supply is relatively limited.
Aluminum's enchantment retention is better, but in the past, most of it was supplied by alchemists to prodigal painters. It was calculated on a gram basis, and it was difficult for mages to produce any results even if they were interested. It hasn't been long enough for mages to have access to aluminum on a small scale. There may be some achievements that are regarded as unique secrets, but the kingdom doesn't know about it, so it means there are none.
In addition to the molding required for the enchantment effect, the aluminum alloy bullet core also has a problem that its density is too small, which will greatly affect the flight performance of the projectile, and even reduce the density of the entire projectile, causing it to decelerate faster after being separated from the enchantment protection. .
Therefore, the aerodynamic design of the entire projectile needs to be redesigned, which needs to take into account the performance of each flight stage. This is a very difficult task. Even if there is some successful experience, it still takes time to polish it.
The related core-wrapping process is tackled by a workshop of a steel plant that is already responsible for the supply of projectiles. However, due to the good performance of aluminum alloys, it is not particularly difficult to use interference fit to achieve a strong core-wrapping process.
There are some other subdivisions in it that I won’t mention, we’ll just have to wait for the finished product.
In addition to the basic shooting attributes, the Ripper enables a new gun sighting system and deployment structure.
Deployment structure, before and after improvement, except for the addition or deletion of some transportation structures to match the existing transportation system, the main difference is that after the installation is completed, the wheels of the gun do not touch the ground, and the performance is more stable in sustained long-range strikes. On the whole, it is still a drag-and-drop type, which is still far from the self-propelled artillery stage.
Wang Qi had participated in militia training, but had no chance to touch artillery sights. He only knew about trigonometric function calculations. The kingdom's artillery sighting system was like starting from scratch. Fortunately, the number of gun types has always been relatively restrained, with only machine guns and mortars. This branch is developing not too slowly.
The main targets of the Heavy Rain series are medium and short-range threats, with a maximum distance of no more than 2,000 meters. They generally only attack targets within a thousand meters. Its main aiming method is similar to that of firearms, with machine sights as the main target.
In the future, the Ripper will be responsible for the mission of fatal strikes against targets between 2,000 and 5,000 meters. The machine sight can only be used for medium and short-range emergencies. In peacetime, it will mainly use artillery sights. The direction is based on the artillery sights of the Styx mortar. experience, and improve it through cannonification.
The biggest difference between artillery sights and machine sights is that artillery sights cannot actually target a single target, especially something as small as a person. To carry out fixed-point clearing of targets outside the visual field, a huge amount of bombs is required to implement high-density area coverage, or to achieve sufficiently high-precision multi-gun coordination.
There is very little room for improvement in terms of bomb delivery. If the single-barreled gun reaches 800 to 1,200 rounds per minute, it will be difficult to increase it. Generally speaking, although the 20 mm caliber is not very thick, it is limited by the reliability of the ammunition supply system, and the limit is also Not too high. It is difficult to add rotating tubes to the magic cannon like the gunpowder cannon. Each tube needs to be equipped with a separate magic device.
Previously, the Heavy Rain Type 1 had a mounted cannon, but it could not be used on the Ripper.
The Ripper's barrel is much longer, which requires some additional equipment weight to balance the center of gravity. The weight of the single-barrel system has increased a lot, and the workload of air transportation, cross-country and combat preparation after assembly is too great.
Perhaps after mass production, a few doors will be assembled for fixed-point use, but this direction will not be considered for the time being before full-scale installation.
It seems that there is another option, which is to increase the size of the cannon and use the area damage of the explosion to achieve killing. This method is also more consistent with the gun sighting mechanism.
It's a pity that it is a false direction.
The kingdom is facing demons and fighting magic monsters. What harm can a little fragmentation damage do to the magic shield?
The academician group for aerial bomb development has actually conducted tests in this area.
A 500kg aerial bomb has an effective killing range of 2,000 square meters against a 3mm ordinary carbon steel armored target. For an unarmored ordinary person simulated with animal meat wrapped in cloth, the effective killing range is 6,000 square meters. Two values. They are all figures that are difficult to survive if they stand within the range.
As for the pieces of meat protected by the magic shield magic device, the effective killing range is less than 800 square meters, which means that people with magic shields have a chance of surviving in the foreign object-free protection zone 16 meters away from the explosion point!
The magic shield used in the test, when the magic level is 0.2 magic, uses full-body protection, which is about one-quarter to one-fifth of the amount of a 4th-level mage. When placed on some high-level demons, it may only be one-tenth or even one-fifth. less. And some shields that only protect one combat surface can have higher defense efficiency per unit of magic power.
The magic shield's protection against shock waves is much higher than that against live ammunition. Due to the random shape of the fragments, the deceleration during flight is dozens of times worse than that of projectiles. As long as there is a little distance, it is difficult to cause damage to the target within the magic shield. threaten.
The charge of a 500 kilogram aerial bomb is more than 130 kilograms of nitrocellulose. Its main function is to clear out unshielded targets within the range. To threaten shielded targets, it actually relies on the magic aerial bomb based on artificial gems, and it has a killing effect. What matters is not the ten kilograms of shrapnel, but the explosion magic and magic burning effects.
The explosive capability of artillery-fired explosives with a caliber of less than 120 mm is two orders of magnitude different from that of aircraft bombs. How many artillery shells are needed to kill a high-threat target? In fact, as long as the caliber exceeds 30 mm, the rate of fire will be reduced to an ugly level, making it difficult to effectively threaten moving high-force individuals, and there is no need to consider it.
Therefore, the technical difficulty of this artillery sighting device is still very high. We are considering equipping the company level with a point-and-shoot observation device that scans the battlefield and displays three-dimensional graphics.
In short, it will probably take a while before mass production can begin. If the projectile part is not considered, the replacement will be faster than the new aircraft.
