Liu Yijiu's ban has still not been lifted. Pen ~ fun ~ pavilion www.biquge.info

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

Long Yaohua became the chief of staff of the Blue Army of the Ninth Academy, Li Yunlong still served as the commander of the Blue Army, and Qiu Yue was also the deputy commander. In this way, the framework of the Blues is completely complete. Tang Tie also became the deputy chief of staff of the Blue Army, which was a bit painful, but Liu Yijiu didn't care about these things.

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

Some of the top core projects in the Ninth Courtyard can be put on hold for a period of time.

The first flight of the 20th Yun20 is about to take place, and the final assembly work has begun to enter the final project.

AWACS aircraft, electronic warfare platforms, etc., are all projects of the Ninth Academy, which can effectively grasp the progress, but air tankers, this lack of Liu Yijiu himself to urge Qin Fei.

The air tanker that was brought back from Iran was given to Qin Fei, and Qin Fei took this as the object of research and began to build China's own air tanker.

This is not to say that an aircraft like the Y-6 can be of much use, but that it must have its own ability to design and transform air tankers, so that the wet nurses of the Air Force can refuel the fighters of the Republic in the skies of China.

The work of copying the F14 of the Ninth Academy has long been completed, but the air tanker on Qin Fei's side has not made much progress.

Liu Yijiu didn't feel that the time was too tight before, many domestic fighters, in addition to the J-10 designed by the Ninth Academy itself, and the J-11 that copied the F-14 had the function of air refueling, and even the J-8 did not consider this ability.

For Liu Yijiu coming here this time, everyone in Qin Fei showed a high degree of enthusiasm.

In the case that many domestic aircraft projects have been launched, and large aircraft projects have even been cut, they can still obtain a large amount of development funds, mainly relying on the financial support of the Ninth Academy. There are projects, money, and a lot of aircraft parts processing business, and the small life is also very prosperous.

Zhang Mingzhi, secretary of Qin Fei, Hao Hongfei, director of the factory, and Zhao Yunhai, chief engineer, led a large group of people to greet Comrade Liu Yijiu, who came to inspect the air tanker project, in the airport.

"Director Liu, welcome, welcome!" As the director of Qin Fei, especially the new director, Hao Hongfei knew that the development of their Qin Fei had to rely on the projects and business of the Ninth Academy, and when Liu Yijiu had just come out of the Yun-10 plane and had not yet stepped on the red carpet on the ground, he stepped forward and stretched out his hands towards Liu Yijiu.

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

"This is Director Hao Hongfei, this is Secretary Zhang Mingzhi......" The people around him knew the situation and introduced Qin Fei's management to Liu Yijiu11.

"What about his Sun Daoqian? He wouldn't be afraid to see me because he hadn't been successful, would he? Liu Yijiu asked everyone, and as soon as these words came out, everyone was a little embarrassed.

Hao Hongfei hurriedly said to Liu Yijiu, "Director Liu, Mr. Sun is currently presiding over all the work of the refueling aircraft project......

"He's not retired yet?" Liu Yijiu is still very dissatisfied.

Qin Fei's people knew that Liu Yijiu was not easy to get along with, and at the beginning, Sun Daoqian, in front of the Minister of the Air Force and the Chief of the General Staff, promised that it would only take six years for the air tankers of the Republic to appear. Now don't say that you haven't seen an air tanker for six years, eight years have passed, and the first air tanker in China has not appeared.

Compared with Factory 132, Qin Fei did not have the conditions for sample trial production and test flight at any cost as the 611 Institute, which was more sufficient, and even at any cost.

"Director Liu, Mr. Sun has been personally grasping this project since he came back from the beginning, so he even gave up the position of factory director." Hao Hongfei hurriedly explained, Liu Yijiu is not good.

"Take me to your workshop to see how it goes!" Liu Yijiu didn't say anything more.

Air tankers, for the republic, are a very strong shortcoming.

He also knew that Qin Fei did not have the same strong strength as 132 and 611, and he was also a third-tier unit, and tens of thousands of people and more family members in the entire factory needed to be fed.

But in any case, the project should not be left unprogressed.

That's eight years later.

Moreover, compared to the previous history, the foundation is much better, at least, there is a Boeing 707 air tanker for research purposes.

Qin Fei's production assembly workshop is much worse than that of Factory 132, although it also produces large aircraft, even compared with the large aircraft factory in Rongcheng that has invested more than 3 billion.

At present, there are only old bombers in China, and their bomb-carrying ability is not strong, their range is not far, and their speed is not fast enough.

Again, there is continuous improvement in the H-6.

Although the factory is very tidy, it still can't hide the erosion of time and years, the brick and wood structure of the factory, with the rough style of the Soviet Union, the mottled walls and the old equipment with paint falling off give people a sense of historical vicissitudes.

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

"Director Liu, are you here? I'm really sorry I didn't go to the airport to greet you......" Sun Daoqian should have received a notice, when Liu Yijiu arrived, he was waiting for Liu Yijiu at the door of the assembly workshop with a group of people, and the smile on his face was a little embarrassed.

Originally, Liu Yijiu's words that were ready to hold him accountable were all withdrawn.

Sun Daoqian's hair was completely white, his emaciated face was almost bloodless, and his eye sockets were sunken and his eyes were covered with bloodshots, which was a typical symptom of long-term malnutrition and lack of sleep, which was the case with many old men in the base before.

"Is the development of a refueling machine very difficult?" Liu Yijiu sighed.

Seeing such a scene, who can blame ruthlessly?

Sun Daoqian nodded, "At the beginning, we didn't fully realize the technical difficulty here. If it is only the transformation of the interior of the H-6 into an air tanker, this problem is not very big. However, when flying at high speed in the air, it is necessary to refuel multiple fighters at the same time, which is really a bit technically difficult. There is a lack of funds, and there is no way to build too many experimental prototypes, so we can only manufacture various prototypes......"

"Prototype?" Liu Yijiu couldn't help frowning.

Sun Daoqian didn't explain, but took Liu Yijiu towards the workshop.

In the assembly workshop, there are several H-6 that are being assembled, and the assembly degree is different.

is used to seeing big planes, and looking at the petite figure of the sixth master, it really can't make Director Liu much interested.

The Soviet An-225 has already been shown in the world!

However, when he saw several prototypes in the workshop, he suddenly felt that the whole person felt a pain!

"Your prototypes are all made of wood?" The corners of Liu Yijiu's mouth twitched and asked Sun Daoqian.

Sun Daoqian nodded with a bitter face, "There are three here, all of which are made of wood, just to verify whether the layout and design are reasonable. After all, after filling up the tank, the center of gravity of the aircraft will change, which also has an impact on the structural strength. Only after testing on these prototypes and no problems will work on the flyable test machine to improve it......"

There is no way to do it, and if the funds are sufficient, or if the technology is stronger, they will not use such an approach.

"Don't you have a Boeing-707 as a reference? Tear that thing down, and you'll have no problem! "The fate of the Boeing-707 that came back from Iran was to be dismantled, and then it became the technical basis of the republic's air tanker.

"We're just disassembling the parts. However, even if it is completely demolished, it will not do much. The maximum take-off weight of the Boeing-707 reached 136 tons, while our H-6 was only more than 70 tons. We have a foundation, but we basically start from scratch. If we use Yun Shi, it can be easily solved, but Yun Shi is too expensive, and we don't have enough funds......" Sun Daoqian said the difficulties they encountered.

Fuel is a liquid that flows towards the lower parts during flight, which changes gravity.

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

"So, what about the aerial refueling technology?" Liu Yijiu weighed in his heart whether to mobilize a transport ten to Qin Fei, and also asked about the air refueling technology.

What he needs is not the kind of nurse who was transformed from the H-6 in history, and can only refuel two J-8III at a time, whether it is J-10 or J-11, its own combat radius and weight are much larger than that of a J-8II, and the requirements for air tankers are also higher. In order to allow them to have a stronger ability to stay in the air and a larger combat radius, the H-6, which can only carry about 30 tons of aviation fuel, is too small.

The air tanker, flying in the air itself, plus a full load, needs to consume a lot of fuel.

"There is no big problem with the aerial refueling technology, but we have not undergone the aerial refueling experiment, and we are preparing to conduct this test during this time!"

"How?"

"It was to use the Boeing-707 to change the refueling device and control system to our own design, and then test refueling in the air. We are about to report this to the Project Management Office of the Ninth Academy......" Sun Daoqian said with some hesitation, Liu Yijiu.

They either report to the military authorities, or to the National Aviation Industry Corporation, or because they don't get funding.
