"Because it looks like F-105, I didn't continue to do it. In 58, we got the photo of F-105, and then drew its three views."
Tang Hua: "The F-105 is considered a fighter-bomber in the U.S. Air Force, but it may not be qualified as a fighter. What is the maximum take-off weight of the aircraft you designed?"
Song Wencong: "15, 6 tons."
"The F-105 has 24 tons, and it has a single engine," Tang Hua said. "Maybe this is the gap in the engine. We don't have many engine models to choose from in our pockets. If we limit it to the technical level, we can still keep up with the times." engine, and that model is even less."
Huang Zhiqian: "After seeing the drawings and materials of MiG-21, several of us also understood that our thinking was too narrow before. People looked at six directions, and we only looked ahead through a small gap. Our design is to follow up While implementing the MiG-21 project, it also picked up the previous brainstorming system to study the basic aerodynamic design of fighter jets."
Tang Hua nodded: "Here, I want to say something in advance. This matter will be notified to you soon through the Industry and Information Technology Commission. The MiG-21 is the last fighter we will introduce."
Huang Zhiqian: ...
"In the future, we will no longer directly import a complete set of drawings and technical materials for fighter jets. You will develop the next-generation and next-generation aircraft yourself. If you can't develop them, the Air Force will encircle the research institute with a dozen large trucks and beat you. I will watch from the sidelines." It’s hilarious,” Tang Hua said with a smile, “but I believe that Shenfei can develop its own design capabilities, and in the next 10 years, it can independently design a fighter that is stronger than the MiG-21.”
……
Shenyang Arsenal.
Liu Nai, Director Qiu Chuangcheng of the First Aircraft Bureau, the light weapons design and demonstration team of the First Aircraft Bureau, and military representatives gathered to discuss the selection of next-generation rifle ammunition.
Tang Hua will not participate in this meeting. Tang Hua is only responsible for grasping the propellant and primer. These two things were completed in 1959, and the specific design will be decided by them first.
Although there are military representatives, designers, and leaders in this conference room, they are all the same: they are all veterans.
Needless to say, the army representatives, the designers of light weapons all came from the war years, and Director Qiu and Minister Liu Nai started from the military factories in the base areas.
"According to Minister Liu's two basic requirements of "a muzzle velocity greater than 950 meters per second and a weight no greater than 7.62 intermediate rifle ammunition", we have produced these six candidate ammunition, and have done basic tests with the modified 50 and 55 steps. ,” said the leader of the bullet research team, “all of them can meet the basic performance requirements.”
“这是口径5.8毫米的枪弹系列，有5.8X39毫米、5.8X42毫米、5.8X45毫米三种长度的弹壳制式。这是6.0毫米的枪弹系列，有6X39毫米、6X43毫米、6X47毫米三种制式。”
Chapter 237, Our Monster Zero
Liu Nai held the ammunition selection meeting in the guest house of the shooting range of Shenyang Arsenal.
The meeting lasted less than an hour, and Qiu Chuangcheng suggested that instead of discussing in the room, go out and hug two boxes.The dozen or so people happily walked out of the conference room, and went from the guest house to the shooting range.
"Da da, da da, da da," the Type 55 in Liu Guifu's hand fires 5.8X39 ammunition. After finishing a magazine, he takes two steps to the next position, picks up the Type 5.8 with 42X55 ammunition, and shoots in short bursts. Hit a magazine.
"Minister Liu, if our Machine Factory in the Shaanxi-Gansu-Ningxia Border Region had these good guys, the Japanese devils wouldn't be beaten to death," Liu Guifu said. The days when the cauldron boiled dynamite"
"What are guns? If we had bazookas at that time, the gun towers in North China would not be able to stand up at all." Qiu Chuangcheng said.
"If there were 108 rocket launchers on the Eighth Road back then, the county would have been promoted."
Liu Nai looked at these old colleagues and subordinates whom he had known since the ordnance industry era of the Eighth Route Army, "Don't pretend to be a veteran. The development of science and technology is very fast, not only the development of aircraft, artillery and missiles, but also guns. Let's talk about rifles. , During the War of Resistance and the War of Liberation, among the captured guns we have seen in more than ten years, which one can be as accurate as the Bayi-style sniper?"
……
From 1949 to 79, the ordnance industry of the Republic was done by the old eight-way veteran military industry.These are people from the generation who fought with real swords and guns in the war. The evaluation of weapons is based on their own personal experience. Whether a gun is good or not, just take it to the shooting range and shoot it.
If there is any priority order for the indicators of light weapons, the requirements of this generation for guns are very simple: they can shoot far and accurately; they can stab hard.
After the retirement of the small arms designers of the first 30 years, the primary requirements for small arms of the new generation of designers of the Republic became... became..., hey, it's hard to describe, but seriously, they also have their own Design goals and priorities.
Therefore, the Bayi-style sniper rifle promoted by Tang Hua greatly shocked this generation of veteran military industry.It turns out that a gun can be shot accurately if it is "accurate". So many ideas, technologies and precision craftsmanship are supporting it.
"You have always said that there is a problem with the burst accuracy of the Type 55," Qiu Chuangcheng said. "It just so happens that the First Machine Bureau obtained their new automatic rifle from the Czech Republic three months ago. You can compare and test it."
Liu Guifu took the members of the light weapons design demonstration team to look at the four VZ.4s on the shooting range.
"This gun looks a bit like an AK-47, but..." Liu Guifu picked up a VZ.58, pulled the bolt, and took a closer look at the receiver. "It's famous, and it's famous."
"Short-stroke piston automatic method," Qiu Chuangcheng said, "AK-47 is a long-stroke piston."
"I just felt that when two bursts were fired, the Type 55 had abnormal vibrations, compared to the vibration of the Type 50 semi-automatic, which was much smaller."
"Of course, the 50-type semi-automatic is the same as this VZ.58, both are short-stroke piston automatic methods."
Liu Guifu continued to study the VZ.58 in his hand, "Czechoslovakia is really interesting, the automatic method is different, this gun is completely different from the AK-47,...that's true, all the parts are different, even the magazine is different Same, what the hell, don’t they all use 7.62x39 bullets?”
Liu Nai: "Czechoslovakia cares about face. After all, it is a small country with light weapons. It has independently designed so many successful firearms before, so it has to come up with one that is different from the AK-47, but uses the same type according to the provisions of the Warsaw Pact. ammunition for the rifle."
Liu Guifu: "Create something different from the AK-47, what about us?"
Liu Nai: "But you don't want to do it differently in pursuit of uniqueness. VZ.58 tells us that automatic rifles don't need to be limited to the structure of AK-47, but you don't deliberately pursue differentiation. Everything is based on 'new guns. Whether it is easy to use' is the standard."
……
"Okay, okay, today we are choosing ammunition, not talking about the design of rifles and guns. The time that rifles and guns gave you was finalized in 1964, which is still early." This group of people has already produced two to three thousand rounds of ammunition , Liu Nai brought the topic back, not because he felt sorry for the bullet, but because the business of the meeting had not yet been settled.
"The bullets of both calibers have high muzzle velocity," Liu Guifu said. "Type 55 bullets have a muzzle velocity of 710. These bullets can shoot more than 900 muzzle velocities. The trajectory is straight, and the accuracy within 300 meters is not bad. But I am a I am worried about whether its lethality is sufficient, and second, we still have to take into account the shooting accuracy of more than 300 meters."
"Yes, our series of guns also includes a small sniper equipped to the squad..." "Minister Tang said this is called a precision marksman rifle."
"It's still called a small sniper. In short, I feel that if these two types of ammunition are used, it may be difficult for a precision marksman rifle to meet the standard. After all, it is necessary to hit a human target at a distance of 400 to 600 meters." Qiu Chuangcheng grabbed six bullets and participated in the One of each of the six types of ammunition tested was placed in a row on the table, and the 5.8X39 and 6X39 bullets were discarded.
"Yes, the long and medium-length bullets use slightly heavier projectiles, which have good long-distance storage speed and are not easy to drift."
Liu Peng: "But this 6X47 bullet is too exaggerated. Although the long-range performance is the best, it is too long and heavy."
邱创成点点头，把6X47毫米弹也撇开到一边。桌上剩下5.8X42、5.8X45和6X43三种弹。
……
Dalian.
Liu Nai was going to stay in Shenyang Armory for a long time, while Tang Hua only stayed in Shenyang for two days. He whipped everyone in the Shenfei Design Institute to make them run, and then set off for Dalian.
Dalian Jianxin Company is still the top brand among the four major arsenals after it allocated some personnel and equipment to establish the Shenyang arsenal.
The comprehensive quality of personnel is the strongest, the technical level of equipment is the highest, the operation process is the most standardized, the quality control is the strictest, and the weapons made are the most "heavy".
The manager of Dalian Jianxin Company and Tang Hua walked into the naval artillery testing workshop. In the middle of the workshop was an assembled naval gun.
The turret is not too big, on it is a 6-tube Gatling cannon.In addition to the gun, a small radar is installed on the upper left of the turret, and an instrument box with an opening is on the upper right.
"This is a sample gun used to test the tilting and rotating mechanism," said the manager, "However, the sample gun used for test firing has also been manufactured and shipped from the factory. It is installed on the destroyer Anshan and will soon go to sea for testing. "
Tang Hua: "Has the ground test of the cannon been done?"
"I've done it. A total of tens of thousands of shells were fired. No, including Taiyuan, it may be over [-]. It's expensive."
Tang Hua: "This should not include the number of test-fired ammunition of your non-Gatling-principle sample gun before. First, double-mounted, then triple-mounted, then quadruple-mounted, and then surrender."
"...Yes. A machine gun with a normal structure also fired a lot of rounds."
……
This gun is not an ordinary small-caliber cannon, but an anti-aircraft gun whose main business is to intercept ultra-low-altitude aircraft and sea-skimming anti-ship missiles. In today's terms, it is called a close-in weapon system.
