Liu Yijiu's ban has not been lifted.

So, he can't stay in the capital for too long.

Long Yaohua became the chief of staff of the Blue Army of the Ninth Court, Li Yunlong was still the commander of the Blue Army, and Qiu Yue was also the deputy commander. In this way, the framework of the Blue Army was completely completed. Tang Tie also became the deputy chief of staff of the Blue Army, which was a bit painful, but Liu Yijiu ignored these matters.

His current purpose is to speed up the development of large aircraft.

Some of the top core projects in the Ninth Academy can be put on for a while.

The first flight of the 20th Yun-Yun is about to be underway, and the final assembly work has begun to enter the final project.

Early warning aircraft, electronic combat platforms, etc. are all projects of the Ninth Academy, which can effectively grasp the progress, but the aerial refueling aircraft, which requires Liu Yijiu to urge Qin Fei himself.

When the air tanker that was brought back from Iran was given to Qin Fei, Qin Fei used this as the research object and began to develop China's own air tanker. When there was no large aircraft like Yun-Twenty, it needed to be based on Yun-Twenty.

This is not to say how effective an aircraft like Y-6 can have, but it must have its own design and transformation capabilities for air tankers, so that the air force's nurse can refuel the Republic's fighter jets in the sky of China.

The work of imitating the F14 in the Ninth Academy has been completed long ago, but the aerial refueling machine on Qin Fei has not made much progress.

Before, Liu Yijiu did not feel that time was too urgent. In addition to the J-10 designed by the Ninth Academy, the J-11, which was imitated by the F-14, also had the function of air refueling, and even the J-8 did not consider this aspect.

Everyone in Qin Fei showed high enthusiasm for Liu Yijiu coming here this time.

When many domestic aircraft projects were discontinued and large aircraft projects were even cut off, they were able to obtain a large amount of development funds, mainly relying on the funding of the Ninth Hospital. They have projects, money, and a lot of aircraft parts processing businesses, and their lives are also very prosperous.

Secretary Qin Fei Zhang Mingzhi, factory director Hao Hongfei, chief engineer Zhao Yunhai and group engineer Zhao Yunhai brought a large group of people to welcome Comrade Liu Yijiu who came to inspect the aerial refueling project at the airport.

"Director Liu, welcome, welcome!" As the director of Qin Fei, especially the new director, Hao Hongfei knew that Qin Fei's development had to rely on the projects and business of the Ninth Hospital. When Liu Yijiu had just come out of the Yun-Senior Plane and before his feet stepped on the red carpet on the ground, he stepped forward and stretched his hands towards Liu Yijiu.

Liu Yijiu didn't know Hao Hongfei, so he just shook hands with him and then took them back.

"This is Director Hao Hongfei, and this is Secretary Zhang Mingzhi..." The people around him knew the situation and introduced Qin Fei's management to Liu Yijiu one by one.

"Where is his Sun Daoqian? He didn't dare to see me because he had never succeeded, did he?" Liu Yijiu asked everyone. As soon as this came out, everyone was a little embarrassed.

Hao Hongfei quickly said to Liu Yijiu, "Director Liu, President Sun is currently in charge of all the work of the tanker project..."

"He hasn't retired yet?" Liu Yijiu was still very dissatisfied.

Qin Fei's people knew that Liu Yijiu was not easy to get along with, and Sun Daoqian promised in front of the Air Force Minister and the Chief of General Staff that the Republic's aerial tanker could appear in just six years. Now, let alone not to mention that he had not seen an aerial tanker for six years, eight years have passed, and the first aerial tanker in China has not appeared.

Compared with Factory 132, Qin Fei is not as good as Factory 611, and even conducts sample trial production and test flights regardless of cost.

"Director Liu, Mr. Sun has been personally catching this project since he came back, so he even gave up the position of the factory director." Hao Hongfei quickly explained that Liu Yijiu was not a good person.

"Take me to your workshop to see how the progress is!" Liu Yijiu didn't say anything else.

Aerial refueling aircraft is a very powerful shortcoming for the Republic.

He himself knew that Qin Fei did not have the strong strength of the 132 and 611st Institute, and was also a third-tier unit. Tens of thousands of people and more families in the entire factory need to be supported.

But no matter what, this project should not be made without progress.

This has been eight years.

Moreover, compared with previous history, the foundation is much better. At least, there is a Boeing 707 aerial refueling machine for research.

Qin Fei's production and assembly workshop is much worse than Factory 132. Although it also produces large aircraft, it is even incomparable to the large aircraft factory that Rongcheng has invested more than 3 billion yuan.

At present, only the old Liu Ye of the country has a weak bomb carrying ability, a short range, and a fast speed.

Similarly, there is still continuous improvement in this.

Although the factory is very neatly clean, it still cannot be concealed because of the erosion of time and the erosion of time, the brick and wood structure factory has a rough Soviet style. The mottled walls and old equipment that have lost paint give people a sense of vicissitudes of history.

Not many people know that the bombers and tankers of the Republic are developing slowly in such an environment.

"Director Liu, are you here? I'm really sorry that I didn't come to the airport to greet you..." Sun Daoqian probably received the notice. When Liu Yijiu arrived, he brought a group of people to wait for Liu Yijiu at the door of the assembly workshop, with a little awkward smile on his face.

Originally, Liu Yijiu said that he was about to hold him accountable, but all the words he said were taken back.

Sun Daoqian's hair was completely white, his thin face was almost bloodless, and his eyes were deeply sunken and his eyes were covered with blood. This was a typical symptom of long-term malnutrition and lack of sleep. Many old men in the base were like this before.

"Is the development of the tanker very difficult?" Liu Yijiu sighed.

Who can still blame such a scene?

Sun Daoqian nodded, "At the beginning, we did not fully realize the technical difficulty here. If we only transform the HVAC into an air tanker, this problem is not very big. However, when flying at high speed in the air, it is really difficult to refuel multiple fighter jets at the same time. There is insufficient funds and there is no way to create too many test prototypes, so we can only manufacture various prototypes..."

"Prototype?" Liu Yijiu couldn't help but frowned.

Sun Daoqian did not explain, but took Liu Yijiu to the workshop.

In the assembly workshop, there are several H6, which are being assembled with different levels of assembly.

I am used to seeing big planes, and looking at Master Liu's petite figure, Director Liu really couldn't be very interested.

The Soviet Union's An-225 has been shown in the world!

However, when he saw several prototypes in the workshop, he suddenly felt ache!

"All your prototypes are made of wood?" Liu Yijiu asked Sun Daogan with his mouth twitching.

Sun Daogan nodded bitterly, "The three here are all made of wood to verify whether the layout and design are reasonable. After all, after filling up the fuel, the center of gravity of the aircraft will change, which will also have an impact on the structural strength. Only after testing on these prototypes does not have any problems will we start to improve the test aircraft that can fly..."

This is a problem that there is no way. If the funds are sufficient or the technical strength is stronger, they will not use such a method.

"Don't you have the Boeing-707 as a reference? If you remove that thing, there will be no problem!" The fate of the Boeing-707 that was brought back from Iran was to be dismantled and then become the technical basic guidance of the Republic's aerial refueling engine.

"We just dismantled the part. However, even if it was removed, it would not be of much use. The maximum take-off weight of the Boeing-707 reached 136 tons, while our H-6 was only more than 70 tons. No matter whether it was the aircraft structure, there was no way to do it. Although it had a foundation, we basically started from scratch. If we used the Y-10, it would be easy to solve, but Y-10 was too expensive and we did not have enough funds..." Sun Daogan said the difficulties they encountered.

Fuel is liquid, and during flight, it will flow towards the low part, which will change gravity.

The structural design requirements for the entire aircraft are relatively high, and at the same time, there are considerable requirements for the structural strength of the aircraft.

"So, what about the air oil tutoring technology?" Liu Yijiu measured in his mind whether to mobilize a Yunshen to Qin Fei, and also asked about the air oil tutoring technology.

What he needed was not the kind of nurses transformed from the H-6 in history. He could only give fuel to two J-8ii at a time. Whether it was the J-10 or J-11, the combat radius and self-weight of the J-8ii were much larger than that of the J-8ii, and the requirements for air refueling aircraft were higher. In order to give them stronger air stagnation capabilities and a larger combat radius, the H-6, which can only carry about 30 tons of aircraft fuel, is really too small.

The air refueling machine, which is flying in the air itself, and with a full load, requires a huge amount of fuel.

"The air fueling technology is not a big problem, but we have not undergone aerial refueling experiments. We are preparing to conduct this experiment during this period!"

“How to experiment?”

"It is to use the Boeing-707 to change the refueling device and control system on it into our own design, and then refuel in the air. We are preparing to report this to the Project Management Office of the Ninth Hospital..." Sun Daogan said with some fear of looking at Liu Yijiu.

They either report to the military authorities or to the State Aviation Industry Corporation, or they cannot obtain funds because they report.
