How Russia overtook America in rapid-fire cannons

26
In Tula, honored the memory of the legendary designer weapons Vasily Petrovich Gryazev. At the Tula State University after the rally and laying flowers to its bas-relief, an All-Russian scientific-practical conference and shooting competitions with airguns were held.
Among the topics discussed at the conference are the theoretical and practical heritage of the Hero of Socialist Labor, laureate of State Prizes and Prizes of the Government of the Russian Federation, Academician of RARAN, Doctor of Technical Sciences, Professor Vasily Gryazev. For more than thirty years he led the rifle-cannon direction in the Tula Instrument Design Bureau. His products in aviation - These are single-barrel, double-barreled and six-barreled guns of various calibres for arming various types of aircraft and helicopters, as well as a four-barreled machine gun for helicopters. On the navy are its six-barreled anti-aircraft guns for naval anti-aircraft gun mounts and the Kashtan anti-aircraft missile and gun complex. For the ground forces, he developed a double-barreled anti-aircraft machine gun for the Tunguska air defense system and single-barreled guns for arming BMPs, BMDs, armored personnel carriers, as well as his designs are located on the S-1 Shell, and it was not without reason that he was called the patriarch of high-fire weapons at the enterprise.


History Vasily Gryazev, the creator of the world's highest-rate cannon, told me in one of his recent interviews.

Worldwide rate of fire competition


Tula from the working-class family, he graduated from 1951 in the year of the weapons and machine-gun department of the Tula Mechanical Institute.

“With this knowledge in the field of weapons and machine guns, I was sent to the Podolsk Institute, then it was called the Research Institute for Small Arms,” said Vasily Petrovich. There he first met the future academician and scientific director of the Tula Instrument Design Bureau, Arkady Shipunov, who graduated from the same institute a year earlier. Two brilliant designers of weapons met, then to never part. According to Vasily Gryazev, their "aspirations to work as designers in creating aircraft gun armament" coincided.

At that time, the whole world competed in achieving the highest rate of fire. The speeds of the aircraft grew, the time of combat interaction between them was sharply reduced, so in a short time it was necessary to release as much ammunition as possible. From the designers of weapons required a significant increase in the rate of fire.

“And we, with the excitement of youth, joined in this global competition,” remembered Vasily Petrovich. “Although we were still novice specialists then, I would say that we had enough sound thoughts.” We analyzed the previous path of development of aircraft armament mainly on one characteristic - the rate of fire. And they considered that everything that was done before was done inefficiently. Because each new system was put into service, having advantages in rate of fire over its predecessors on 15, a maximum of 25 percent. We considered that this is a scanty figure and threatened to increase the rate of fire two to three times.

After several unsuccessful attempts in 1958, they finally developed a double-barreled automation scheme, which in the caliber of 23-s and 30-mm of millimeters showed a rate of fifty shots per second. Thus, their gun three times surpassed the performance of all analogues available at that time. After the first success, designers faced a dilemma: dwell on this achievement and develop the theme for different applications, as most of their colleagues do (when successful development appears in any direction, they become locked in it, trying to spread the idea to everything else), or develop farther. They preferred the second path - “due to the great greed to work”, they decided not to stop there, and once again try to triple the rate of fire.

Gryazev and Shipunov were successful: though not immediately, but many years later, a six-barreled 30-mm gun, which had a rate of 100 shots per second, and an 23-millimeter six-barreled gun, which produced 170 shots per second, were adopted.

- Try saying "22" is a second. And imagine: while you said it, 170 shells are already gone, - explained what the rate of fire, Vasily Petrovich. But it was ahead, and then, in parallel with the work on fine-tuning their first gun, they began to develop a six-barreled gun.

And there was nobody to tear off


“But we faced almost insurmountable difficulties,” the designer recalled. - The fact is that any development in any field relies on previous achievements, and often many decisions that have been made earlier are used in promising developments. For example, in aviation it is believed that if a new aircraft does not contain fifty percent of previously developed parts, it will not fly. In some way, a new sample must necessarily be connected with previous ones in many, many nodes. And in the direction of the six-bar automation scheme we had no predecessors. There is no one to spy, borrow. In addition to the American six-barrel Gatling and the Russian bullpen Baranovsky there was nothing. But those systems were manual - the man twisted the gun by hand and she fired, naturally, very rarely and with a very small rate of fire. In principle, if you turn faster, they could give a high rate of fire. But how to do it - we could not find a single solution.

The work of domestic designers, who were engaged in the development of such multi-barreled weapons using an electric motor, ended in failure. At the same time, there was scant information from the United States that the American company General Electric was developing a 20 six-millimeter six-barreled cannon "at a fantastically high rate."

- Of course, many years later, when she appeared in service with American aircraft, this information reached us to the full. But even if we recognized them at that time — and it was 1958 a year, we would still not be able to apply them. That gun worked on an electric motor with a power of 25 kilowatts. The Americans could afford it - apparently, they were compliant aircraft designers. And, having become acquainted with ours, we knew for sure: if we would have offered such a solution, our aviation would simply drive us out. After all, such energy on an airplane should be obtained somewhere. The aircraft designers told us: behold, gentlemen, an onboard station with direct current in 24 volts and "not a single gram" more. So we had to create a system that does not work on the basis of an external source (hydro or electric drive), but somehow contrived to use our own internal energy shot to make this gun work. Such a thing we did. We invented a vapor engine for a six-bar automation scheme with continuous action. He worked like an internal combustion engine - he took a portion of the powder gas from the barrels when fired. At the same time, we made a good drive: if the gun shoots, it rotates and reloads, as soon as it finishes shooting, everything stops. However, we could only start shooting with our hands. But on the plane, no one will approach the gun - it is located the devil knows where, and you still need to get to it. So all this control had to be done remotely ...

In the end, they did it all. In general, such samples in a limited time is very difficult, almost impossible. Americans, for example, 20-millimeter cannon "Vulkan" made 12 years. And Tula designers engaged in this direction from 1958-th to 1961, when, finally, the necessary technical solution was found. Soon the aircraft ordered them a 23-millimeter six-barrel cannon, and the Navy for the defense of ships - 30-millimeter.

- You know, when she shoots at a frequency of 170 shots per second, it seems like an animal howl. The target has already been destroyed, there are clouds of smoke, the gun has already stopped. But 150 shells that have already been fired are still flying to the pre-empt point and eagerly looking for a target. The picture, - as Vasily Petrovich described the first test of his gun in the sea.

The general was dancing a jig


When industrial armaments were tested, General Yermolov, as Gryazev said, danced on the jig deck with joy. According to him, these guns can be compared only with the American "Vulcan" - there are no other analogues. But our rate of fire and more energy intensity - do not compare.

“She drank a lot of blood, was created in smoke and flame,” the designer recalled. Between the first "shooting device" and the mass-produced product were 100 prototypes with various changes and corrections of deficiencies, a million warheads and 15 years of work. After all, in the same aviation there should be no delays in shooting. This is possible in the Kalashnikov assault rifle, but not in the air cannons. If during the tests the sample did everything, but there was a hitch at the last shot - it is considered that the gun did not stand the test, the production of guns stops, the task is given to find the reasons. Everything needs to be refined and after that another 2 “penalty” sample to be tested. But in the end it turned out the most rapid-fire weapons in the world.

In 1974, the gun was adopted for aviation, and a year later - for the Navy. Now, on any snapshot of warships, you can see these guns. For example, the flagship "Peter the Great" is equipped with six-barrel cannons, the total rate of which firing is 200 shots per second. They are designed for self-defense of ships against anti-ship missiles - shoot them in the air. And in aviation, the 23-millimeter cannon completed the armament of the heavy attack aircraft of the Sukhoi design.

- If you go to the Mig 29 on the left, you can stroke the barrel of our gun, and in the SU-27 it stands on the right, in the MI-24 helicopter P on the side you will see the 3-barrel 30-mm gun, invisibly there everywhere. The gun is a component. No one will buy a gun to shoot from her shoulder, ”said Gryazev. - Always the automatic machine for the shooter is a complete product, and an aviation cannon only for an aircraft can only be sold together with an aircraft. Not insulting - cheaper. The main thing for us was to preserve our honor, to say that we were entrusted with such responsible work, and we did it. And the fact that it is a component or not - was not in our thoughts.

    For the first time in the world, A. G. Shipunov and V. P. Gryazev developed small-sized and lightweight, but at the same time very powerful autonomous gas evacuation drives for automation, as well as high-speed pneumatic and electrotechnical starting devices and fire control systems. Flowing and evaporative water cooling systems were created for the rotating barrel block. In the end, domestic aviation received the world's fastest firing guns: 10 thousand rounds per minute! Among them is the world's fastest six-barreled cannon: the 23-mm gun GS-6-23 and its upgraded version GS-23-6-23М designed for the Su-24 front-line bomber as a movable cannon mount mounted in the aircraft’s design and in a movable version SPPU-6 cannon container, as well as the MiG-31 heavy fighter-interceptor in the version with a linkless power supply system.

    Frankly, a much more detailed and competent publication could be made on this subject. negative But then I read it to the end, I saw who the author was and everything fell into place. The minus did not set only out of respect for the designers.

      I even saw how shells from such a gun fell into the water almost at the side. True, it was a long time ago. Somewhere in the 64th.

    Yes, the Americans built their A-10 Thunderbolt around a six-barreled gun. And proud of it lol
    And we are proud that we created an analogue easier, faster and in a shorter time thanks to the outstanding brains of the era of the Great Country. good

      and now they can’t do anything with A10 ... cannot be upgraded ... the submachine gun turned out .. the cannon is integrated into the power structure of the airframe .. the cannon is not needed and the A10 is also the same .. And our su 25 doesn’t become obsolete and well done despite for age !!

    On the A-10 gun 7 barrel. And not everything is so millet when comparing. Somewhere the resource and accuracy is better, where the rate of fire and weight. It is necessary to compare on one device for certain conditions of use

    These two people, Arkady Georgievich Shipunov and Vasily Petrovich Gryazev, are the pride of Tula. Eternal memory to them. Nobody had such achievements as theirs. And the fact that the current state of affairs among Tula gunsmiths is encouraging, their personal contribution is enormous! A.G. Shipunov recalled how he worked almost all day, leaving only 8 hours to sleep!
    The GSh brand, among gunsmiths, is like a Quality mark, a standard of reliability and high performance characteristics.
    Their glory will live like the glory of the legendary Lefty.
    By the way, for those who are not in the know, Lefty had a real prototype and his name is known ...

    How Russia overtook America in rapid-fire cannons

    Kill publications begin with the adverb "how" wassat As a rule, they are written by amateurs negative This "ideologically sustained" article does not meet the high standards of "VO" and contains a lot of inaccuracies and frank "blunders" negative Having read it from a person far from aircraft armament, a false impression can be created that, before the unconditionally brilliant Gryazev and Shipunov, we had no other famous designers involved in the creation of aircraft guns.

    A good designer who worked for our country. Somehow in Tula it turns out that way.
    Most of the article is the memoirs of Vasily Petrovich himself. Only then - smears, applied by the correspondent-correspondent-journalist. And the first from the second is very distinguishable.

    in Tula, the training center 106 VDD and the firing range where fast-firing guns are being tested are located nearby. So, due to the glass factory, they completely change once a year (well, something like that). .

    Thank you, old people, that thanks to you we live in a free country.
    Almost 70 years ago, they created the best weapons in the world, and we are still fighting them.
    Well, what about our modern designers? Do they even exist?
    Why do the descendants of the kangaroo beaters collect a gun of 1 rounds per minute. And ours, as I understand it, they all went to the managers, and whoever remains can only "upgrade" the main gun, well, screw the Picatinny rail there, hang the flashlight - that’s the main gun.
    Where is the breakthrough?

      But why actually a rate of 1 million shots? This toy was made in order to write about it in the book of records. the same ak-630-2 has the absolute density of fire, at least at short range.

      Today it is extremely difficult to make a breakthrough in a gunshot, it’s like, say, “bows” at one time reached their peak and were supplanted by “peepers” and “bombers”. ammunition is another matter, progress is constantly being made here.
