After giving the gearing project team a commitment that the company would now officially start paying overtime wages, Yang Hui went to the Liyang plant to see the production of turbofan 10 engines.

Since the official start of the production of the turbofan 10, the production number of nearly 100 units has been reached, which is quite gratifying, but after the distribution, it is far from enough.

Jianjiao 7A, Jian-74, and Jian-75 will all use this engine, and the domestic army does not have money in these years, but there are many aircraft purchased.

The J-7 aircraft purchased every year also have fifty or sixty planes, and the current J-7 series aircraft are more advanced, and the price increase is not much, which is more tempting.

The army has long pulled out funds from all sides, and the orders prepared are not old or young. Even Yang Hui got the news that the J-75 aircraft, an Air Force fighter developed by Jinguancheng, does not need to consider the harsh environment and multi-purpose performance of the Navy like the J-74.

At the beginning of the year, the finalized production has been realized, and now the turbofan 10 produced by the Liyang plant can only meet the use of J-75 and J-7A.

After the Southwest Science and Industry Co., Ltd.'s own J-74 was finalized, there were naval purchases internally, and large orders from Thailand and Iraq externally, and the requirements for the output of turbofan 10 engines were even more severe.

"Now that the engine production has reached the peak of the production line, this turbofan 10 engine line is an improvement from the turbojet seven engine line. The factory's turbojet 7 engine production line was designed with an annual output of 100 engines, and is now at full capacity. ”

Walking and walking. The deputy director of the Liyang plant began to complain to Yang Hui, and now the turbofan 10 is too popular, and the Liyang plant works overtime every day to produce. That's not satisfying.

The establishment of a new production line was on the agenda, but the construction of the production line was not so simple, and if the new production line had been built according to the standards of the turbofan 10 engine, which had been improved from the turbojet 7 production line, it would have been put into production long ago.

For no other reason, the old-fashioned production line is inefficient and relatively simple to build. Many of them are produced on special machine tools, and it is almost quite difficult to improve the production of other models. When the turbojet 7 production line improved the turbofan 10 production line, Southwest Science and Industry spent nearly 60% of the cost of the entire production line.

On the other hand, the efficiency is too low, and there are almost no CNC machine tools on the production line. The only few machines are set up for some parts that require high precision, and its role is to improve the accuracy of the parts, rather than the biggest advantage of CNC machines: high efficiency.

"I know the difficulties of the Liyang plant now, and the production capacity is indeed seriously insufficient. The company has known this for a long time. As you know, the machines for the new production line have been in the process of being procured for a long time. The problem now is that dozens of various CNC machine tools are still in the process of manufacturing and transportation, and the formation of productivity in place is probably already in the autumn of this year. ”

Southwest Science and Industry is indeed relatively rich, every year through various channels to purchase a variety of CNC machine tools is indeed a lot, but to use this thing of the factory is also a lot, machine tools have not yet arrived, has long been allocated.

The engine production line of the Liyang plant this time has been the culmination of Yang Hui's many efforts. NOTICE:

"According to the original plan, your production line with the highest degree of numerical control in China will take at least 88 years to be in place. Now that I have done my best, I have even misappropriated the equipment of other factories, and the CNC machine tools that were originally intended to be used for the construction of the fast reaction center have been taken, so you don't have to say anything more. In a word: strictly control the quality! ”

The quality problem is more important than the sky, "holding the army's property with one hand and the lives of comrades-in-arms with the other" This is a string that the military industrial front has been tightening and never dares to relax, but Yang Hui still has to repeat it again and again.

Liyang plant knows the original completion time of the new production line, and now the production line can be built at least half a year ahead of schedule, which is already a very good result, and Liyang plant naturally has nothing to say.

"To ensure that every engine from the factory is produced in strict accordance with the process requirements, there will never be a major quality accident like the last turbojet seven engine."

Speaking of which, the deputy director is also ashamed, although several years have passed, but every time I think about it, I still feel a hot pain on my face.

Because of this, the entire Southwest Science and Industry has a quality rectification, from the aerospace system quality control experience, and now it is indeed very good.

Due to the fact that Jianjiao 7A and turbofan 10 invested a lot of money in the test at the beginning of the development, the loopholes in the design have been almost filled, coupled with strict quality control, the aircraft produced by Southwest Science and Industry in recent years have not had any negative big news.

Back to Anshun, where the most dense units under the Southwest Science and Industry Group, this is the office area of the Southwest Science and Industry, and Yang Hui also works here. First of all, the news of the full implementation of the overtime pay system will be released, and then other things will be said.

Now Yang Hui saw this team, there are two J-74 planes equipped with a complete fire control system, they have been pushed onto the runway, and there is also a Y-7 plane, which is about to depart from the southwest science and industry to the naval aviation base camp in Nanhai.

As long as the one-month test is completed, the J-74 can get the final production authorization, which means that the production line of Southwest Science and Industry is not only responsible for the production of J-74A, but also responsible for the production of J-74 aircraft.

Yang Hui is now coming to the airport, it is for the team, the hope of the navy and the southwest science and industry are pinned on this team, after they succeed, the republic's control over Nanhai will be greatly expanded.

"Chief Master Yu, everything depends on your test results this time, I am waiting for the good news from you at any time in the company!"

Finally, after shaking hands with the chief division, the team began to get on the plane, although the Yun-7 aircraft also has a civil aviation version of the plan, such as the Yun-7 200, and even the later Xinzhou series aircraft are developed on the basis of the Yun-7, but now it is only a military transport aircraft, and all aspects are indeed somewhat unsatisfactory.

Yunqi aircraft is a little slow, but the range is not bad, this flight to Nanhai is just right, as for the comfort, don't think too much, a group of people sit on the plane, wear earplugs, with the rapid operation of the turbo five engine, Yunqi aircraft quickly flew into the sky.

Seeing Yun Qi slowly go to the southeast, the two test machines used for testing in the back also started the engine, each with two auxiliary fuel tanks, although a little small, but fortunately did not occupy the two hanging points on the inside of the wing.

The auxiliary fuel tank of the J-7 aircraft is relatively small, and the J-74 aircraft continues to retain this point in the development, so that it does not directly change the auxiliary fuel tank hanging point to the heavy-duty hanging point on the inside of the wing like the J-75 designed by 0611.

The innermost hanging point has a strong load-bearing capacity, 0611 even the auxiliary fuel tank has been redesigned, and the new auxiliary fuel tank is a large circle larger than the small auxiliary fuel tank used in the original J-7 series, and the transfer range is indeed much longer than that of the J-74.

For this reason, the Air Force has been showing off to the Navy for a long time, and it seems that after having a large auxiliary fuel tank, the J-75 will be much better than the J-74

Fortunately, the navy is still relatively rational and knows that it is only suitable for the air force, and the heavy hardpoint of the navy's J-74 aircraft is generally used to hang anti-ship missiles when performing combat missions.

As for the range issue, the navy said that it now has the ability to refuel in the air, and these are not problems, it is a light multi-purpose combat attack aircraft, and everything should be attacked, and those who hinder the navy's attack on the sea are heretics, and they must be severely attacked or even burned to death.
