The shooting task did not end there, and seeing that Bersky had already closed the lens cover, he pulled Rygushkov and walked over. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Sir, do you have any other shooting tasks? Our film is still very limited. ”

"Of course." Yang Mingzhi said: "Next you should go to the arsenal to shoot, I remember for a few months, there were no photos about the arsenal, so then you follow the director of the arsenal." ”

Rygushkov has always been excited, not only because it is rare to take pictures, but also because the commander is planning to photograph the arsenal as well, which is a very proud thing.

Bersky nodded: "I naturally obey the commander's order, but it seems that the chief will not go in person, which makes me a little worried." ”

"Don't think too much about everything! Just follow Rigushkov's orders! I'm very busy with my work, and now you two hurry to the arsenal and make sure you get the job done today. ”

Without the adviser Rigushkov, nothing will affect the institute.

Throughout the morning, in addition to the small episode of photography, some remaining problems were solved in the research and development of individual rocket artillery.

After lunch, Yang Mingzhi also returned to the institute early. His task is to summarize the results of each researcher and make the final coordination and changes by himself.

Mathematical modeling of the rocket's flight condition is a key priority in the entire development program. After all, the range of this rocket for the target set by himself should reach eight kilometers, that is, the range of the 75-mm howitzer.

In the spirit of the old Maozi's mentality, if you want the rocket to fly so far, you must make a stupid black and coarse thing, and the range of the Katyusha rocket artillery is about eight kilometers.

Yang Mingzhi knows very well that his subordinates have been carrying out R&D and design under great pressure.

The caliber of the rocket is limited to 107 mm, the length is 90 to 100 mm, and the maximum range is again eight kilometers. In Yang Mingzhi's view, the launch system of this weapon he engaged in was copied from the PF98 individual rocket launcher of that plane, and the projectile body was a direct copy of the farm tool 107.

After all, this 107 mm guy, its development itself refers to the Soviet Katyusha, after a series of improvements, the size has been reduced but the performance has been greatly improved.

In fact, the subordinates have at most one attack, and most of the process of researching this weapon has to be operated by themselves.

Therefore, in the afternoon of this day, Yang Mingzhi did not leave his seat for a single step, until a melodious dissolution call came into the design department.

"Oops! Most people's day's work seems to be over! Yang Mingzhi, who had been lying on the desk for a long time, had a reason to relax at noon, straightened his waist and stretched his arms and sighed.

Seeing that the chief is like this, the others are also relaxed. Popov was a little unhappy and said solemnly: "Comrades keep working!" If the chief does not order the disbandment, everyone must not relax! ”

Yang Mingzhi smiled with satisfaction, and then stroked the table and stood up. My legs have been doing it for too long, and my lower abdomen is also a little swollen, and I didn't smoke a cigarette this afternoon, and I didn't go to the toilet once.

With the help of the light of the kerosene lamp that had been lit up, knocking on the table where a large part of the drawings had been completed, Yang Mingzhi couldn't help but feel a lot of emotion.

Your own foresight is the greatest advantage, including the development of this weapon. The Soviets continued to refine the design of the Katyusha, and just after the end of the war, they obtained a lot of information on the German V2 rocket. The two long-term research successes of the Soviet Union and Germany were also successfully obtained by the Chinese, and after the re-development of the genius scientists of the motherland, various types of rocket artillery and missiles were delivered to the troops.

It is precisely because in the decades of revolutionary wars that the poor firepower has suffered a great loss. In 1963, this kind of 107-mm rocket artillery equipment with extremely low cost and high cost performance, nicknamed agricultural tools, was popular in many third world countries for the next half century.

This little butterfly of his own made the farm tool 107 born twenty years ahead of schedule!

Yang Mingzhi estimates that his R&D progress has been completed by 80%. Judging by the drawings alone, the mathematical model of the projectile body is already perfect. The calculation of the ratio of propellant and thrust, the relationship between the propellant reserve and the flight time, and the final weight of the missile body are combined to form an incomparably complex set of equations.

I am not a mathematician, just because I had to tackle tough problems in this area when I was in school, so that my mathematical ability is also outstanding in this plane. And this group of young hairy people, the reason why they can come to this weapon design bureau is precisely because they are related majors. They are not experts in weapon design, but they are also excellent at mathematics.

After careful calculations, the projectile body has theoretically met the design expectations, and there are still many corners left to continue to consider.

For example, there is a problem with the folding tail, the firing-mercury ignition method, the mechanical aiming device, and the angle-adjustable launcher.

These are all small problems, and Yang Mingzhi couldn't help but sigh when he thought of them.

After a few strong kicks on both legs, he finally regained his strength. Yang Mingzhi turned to face everyone, clapping his hands to attract everyone's attention.

His face was full of joy, and he said excitedly: "Comrades, the main project of our conventional rocket artillery has been developed, and there are only some details to be improved.

In addition to this is about the project of transforming ethylene oxide cylinders into rocket artillery warheads, for which we need to develop larger rocket artillery, I think that after the completion of the 107mm rocket launcher, there will be a lot of information for its further development.

Therefore, according to the R&D schedule, the special individual rocket launcher of the 107 mm caliber type that we are now fully developing can be said to be basically completed!

I know you're all tired right now, so I've decided to take the rest of the day and stop fighting tonight! ”

As soon as they heard this, there was a groan in the entire research institute, and everyone sighed as if they were unburdened.

In the two days of scientific research, everyone has put in great effort. Compared to the physical exhaustion brought about by the routine daily five-kilometer cross-country and comprehensive training of ordinary soldiers, the researchers have been fighting with complex equations for two days, and their brain cells are groaning, and now they can finally rest?!

However, there are one or two people who got cheap and sold well, and they stood up and claimed that the research and development was not over and that they should not waste time.

"Sit down, sit down!" Yang Mingzhi was a little impatient, "It's good to work hard, but it's bad to be tired and your brain is bad." You people are no less than the combat heroes on the front line, and the research and development tasks have been completed ahead of schedule, so you heroes should give me a good rest! ”

As he spoke, Yang Mingzhi called Popov up: "You pay attention, I don't allow researchers to work overtime tonight, and everyone rests early after dinner." Recharge our energy, we continue to engage in research and development!
