Ak47, whether it is a one-vote shooter or a movie, has long been out of the face, with the power of a small friend with a shot and a huge output and the comical style formed by the use of his black maize, AK47 should be the most familiar rifle.
But AK has long been said to be a rotten street, so the dog today to take a look at AK his father Kalashnikov how a handful of and a handful of urine pulled him up.
On the eastern front in 1943, the Soviets and Germans fought fiercely, and one day, the Soviets found that the Germans used a new weapon that was like a submachine gun when it was automatically fired, but had a range of three or four hundred meters - the MP43 (the predecessor of the STG44)
The Germans developed a 7.92*33 intermediate power bullet, which made the muzzle kinetic energy of this automatic rifle reach 1900 joules and an effective range of up to 400 meters.
Therefore, the power and range of the stg44 rifle are far more than one vote of Bobosha, and the rate of fire is far more than a vote of large bolts and semi-automatic fire sticks, and the effective range of 400 meters is actually similar to the visual effective range of the big bolts. Several STG44s opened fire on the hideout of the old maozi, and the dense bullet whistling sound was like a storm, and the Soviet army was blindfolded for a while
On the other hand, as early as 1928, the Soviet Union had considered reducing the charge and shell length of rifle bullets for the launch of individual automatic weapons, and when the Eastern Front began to fight, Maozi also realized that in the mechanized combat mode, the infantry engagement distance was actually quite short, and there was no need to hit a fire stick that could be hundreds of meters larger. But changing the ammunition type is a big deal, and the Soviet military high-level does not dare to be the first to eat crabs.
Thanks to the Fierce Storm of THE Eastern Front Germans with MP43, the old Maozi said with tears that he was really fragrant ~ and strengthened his determination to develop the intermediate power bomb. In December 1943, Lao Maozi produced a 7.62*41 intermediate power bomb
Comrade Kalashnikov, who had returned from his wounds, also began to develop a new gun with his friends.
Kalashnikov thought the M1 Garand semi-automatic ding-dong machine used by a bunch of American little Bourgeois was very interesting, so Mr. Ka quickly concocted the SKK-44 semi-automatic carbine gun using 7.62*41mm bullets
Clear-eyed people know what is going on at a glance ~ (Garland: Wife you listen to me explain, this is really not my birth) SKK-44 semi-automatic rifle uses the principle of air-conducted automatic, the gas pipe is above the barrel, and the Garand gas pipe is in the lower part of the barrel (the one below the SKK-44 is a bayonet ~)
Their air conduction system is still a little different, Garland's piston and bolt are connected, standard long-travel pistons. The SKK is detached, which belongs to the short piston. But the locking is all bolt rotation, or two symmetrical locking shoots, it is obvious that this blocking method is a simple and rough copy of the American M1 Garand semi-automatic rifle.
But in the end the SKK-44 semi-automatic rifle was defeated by the Simonov family's SKS. By 1946, Old Maozi felt that semi-automatic was not at all enjoyable, and the German STG44 was also fully automatic. Bidding for automatic rifles began, Kalashnikov was generous enough to eat ready-made meals, and the entire structure of the SKK-44 semi-automatic rifle was transferred to the newly designed automatic rifle, the AK46.
This is the AK46 prototype gun, and the receiver and magazine are stamped and riveted. There are two types of launch modes, single-shot and fully automatic, and the safety/speed handle is on the left side of the receiver.
Pistol grips, stocks, front grips and handguards are all wooden, muzzle brakes are cylindrical, with three large round holes on the left and right sides, and the AK-46 still uses 7.62 * 41mm.
The Prototype No. 1 gun is 895mm long, the barrel is 397mm long, weighs 4.1 kg, and has a scale scale of 800 meters, while the actual effective range lasts 400 meters.
The second prototype gun was slightly improved on the basis of the first prototype gun, the second was 950mm long, the barrel length was extended to 450mm, and the weight was also increased.
The prototype gun No. 3 is a folding version of the prototype gun, mainly for paratroopers and special forces
When the 47th year was officially selected, the AK-46 rifle had a large number of problems in the test (violent operation), easy jamming, poor environmental applicability, poor ergonomics, and the test also exposed that the performance of the M43 type 7.62 *41 bullet used at that time was not as good as the 7.62 * 33 bullet of the Degun.
However, what is interesting is that at that time, the one-vote competitors were too scummy and all eliminated. The AK-46 was lucky enough to pass the first round of testing.
After returning home, Kalashnikov improved the AK46 rifle, and in 1947, Kalashnikov changed the receiver to stamping, and the structure was changed to a long-stroke piston gas conduction integrated with a bolt piston to improve reliability, and the fast and slow machine was mounted on the right side of the gun, which led to the familiar large paddle design
This was the AK-47 Prototype Gun No. 1, and in the same year, Lao Maozi could not stand the slag of the 7.62*41, so he redesigned the M43 bullet, shortened the shell length from 40.4mm to 38.6mm, and redesigned the warhead. Only then was the 7.62*39M43 bomb successfully developed.
(The picture shows 7.62*39mm and 7.92*33mm)
Improvements continued, such as the addition of excess conduction to the Prototype II, which made the thrust of the piston and bolt more ferocious and the automatic machine more reliable. By 1948, the AK47 Prototype III gun finally stood out. Later, everyone knows the ending, the AK-47 from 1949 began to equip the Soviet army, improved to a cheaper, simple, reliable AKM, but also became the standard rifle of the entire socialist camp.
To this day, the AK-47 and his disciples are still a weapon for the opposition in every conflict
