"Although it was an accident, we must take it seriously." Qin Zhenhua said: "If our tankers are on the battlefield, aim at the enemy's tank with confidence and then cannot fire it, not only will they lose the fighter plane, but they will also let us ourselves
The tanker is in danger. This is a mistake that is absolutely intolerable. It is a crime."
Qin Zhenhua said it was very serious, and at this time, Xie Huimin, who was opposite, also looked serious: "Yes, we will not let this happen. We may have discovered the root cause of the problem."
Xie Huimin is also a master, and he has a high sense of responsibility to the country and the army in his heart. Of course he knows what this means.
In a tank duel, the distance is only more than one thousand meters. At this distance, the two sides compare who is faster and who is more ruthless. Among the firepower indicators of the tank, one of the most important indicators is the rate of fire, even if it is a vehicle
When the tank faces more than a dozen tanks on the opposite side, as long as the fire rate is fast enough, it can wipe out the opponent.
During World War II, the German tanks were famous for winning more than they were. During the Cold War, NATO faced the rolling armor torrent of the Soviet Union on the opposite side, and planned to win with mass.
At this time, tanks are in a daze? This is absolutely not possible.
Therefore, the first thing to do is to find the cause of this occasional failure.
So, what is the reason?
The experts from the Second Machine Factory are the most powerful artillery experts. After carefully studying the design drawings and comparing them repeatedly, they finally came to a conclusion.
"Our firing needle extends and retracts by pressing the rotating shaft on the blast latch against a pin on the curved arm. In order to avoid interference with other parts, the pin is semi-cylindrical.
Moreover, the way to connect is riveting. This pin begins to loosen after being squeezed by the latch body spiral shaft many times. In addition, it fires on the vibrating tank, and this kind of thing appears during the bumps.
Unexpected situation, not tight."
Several experts studied here and finally came to such a conclusion.
"Then how should we solve it?" Qin Zhenhua asked.
If you have a specialty in your career, how to build artillery is their business. How to improve it is naturally the responsibility of the people from the Second Machine Factory.
"If you want to improve this, it is also very simple. Just shorten the fitting part of the pin and the curved arm and use electric welding so that it will not loosen."
It used to be riveting, but now it has been changed to electric welding, so there should be no problem, right?
"Can this ensure 100% effective?" Qin Zhenhua asked.
Xie Huimin shook his head: "Zhenhua, you are so difficult. We all know that as long as it is a machine, there is a special parameter called integrity rate. We will not make 100% guarantee for any weapon and equipment. That is not
If we comply with the actual situation of engineering, we can only try to minimize the probability of this error."
As long as it is a machine, there will always be a chance of failure. Even in the aerospace industry, it is 99.98% to say that the reliability of the Long March 2 rocket is 100%.
Although it is unlucky for the frontline soldiers to catch up with the remaining zero points, the fact is that we will reduce the probability of failure as much as possible, but this can only be reduced and cannot be eradicated.
"I have an idea." Qin Zhenhua said: "We are now using two firing mechanisms: electric shock and mechanical firing. These two mechanisms do not interfere with each other. In order to improve the reliability of firing, can we make this happen?
The two firings are combined?”
Electric shock means to directly stimulate the bottom fire of the shell with current. The bottom fire of the shell has also been improved accordingly to adapt to this kind of firing. The other, mechanical shock means to use manual firing of the pressure rod to fire. These two methods
, they have nothing in common with each other, and they are also common methods of firing tanks and guns. Now, Qin Zhenhua actually said that they should combine these two firing methods together?
What does this mean?
Xie Huimin and others were thinking about Qin Zhenhua's plan, but Qin Zhenhua did not refuse and said his thoughts directly.
"My idea is to add a special electromagnet mechanical firing device." Qin Zhenhua introduced: "While we press the button, we not only directly stimulate the bottom fire of the shell through the current, but also fire the distribution box through the firing of the power distribution box.
, Entering the electromagnet, the electromagnet pushes the firing top plate, drives the firing top rod in the tail of the cannon, and firing the firing top iron. The next steps are the same as our manual mechanical firing method."
Electric shock is to directly stimulate the current, mechanical fire, and the bottom fire is to complete the fire by impacting the needle. Now, what Qin Zhenhua said is to take two routes. Using this method, the two methods are perfect.
The ground is combined together, and while the electric shock is fired, the mechanical fire is also started through a special electromagnet. In this way, if the electric shock is not successful, the mechanical fire will be directly repaired.
That's right, after all, the current is faster, and electric shock is only ten milliseconds enough. For electromagnets, such as firing, requires at least eighty milliseconds because of the movement of various mechanical components.
The two firing methods can greatly improve the reliability of firing. In case of electric firing, the electromagnet firing can play a role when various problems cause blindness.
After hearing Qin Zhenhua's introduction, several experts present were stunned and thought seriously. Xie Huimin spoke first: "Zhenhua, your idea is very good, but our weapon design plan requires
The structure is simple and the function is reliable. If you do this, it will greatly increase the complexity of our structure."
Inheriting the characteristics of the Soviet Union, the domestic emphasis is on the simple structure. Once the system becomes complex, the probability of errors will increase.
"Originally, in order to satisfy electric shock, we have added insulating parts to the firing needle and the latch body. Take the most direct example, our firing needle is telescopic, because when closing the latch body, the firing needle is fired.
Only by slowly extending out to resist the fire of the shells is because we are afraid that the shells will hit and fire the shells when they are closed directly. These are not easy anymore. Now, we have to add another set of electromagnet mechanisms, so we will
It greatly increases the complexity of the system."
The design of artillery is a very profound science, and the same is true for a simple firing. The use of mechanical firing is the most reliable, but the long press and press the button of the cannon is the most convenient, so there are two ways to electric firing and mechanical firing. Now we need to
