Yao Taihang was once again attracted by Li Lu's paintings, and this time, he believed it himself. Although the 460 factory is a military aviation development plant, there is no strict distinction between military and civilian use in aviation development and development. The Spey engine, which was introduced in the seventies, was said to be a civilian model, but in fact the troops were considering installing it on military aircraft.

Although Li Lu knew that the JH-7 developed for 50 Spey engines was not purchased by the large user air force in the end, the manufacturer would receive an order from naval aviation on the verge of despair, thus giving a new lease of life to an excellent sea-to-ground attack aircraft that could maintain a transition for 30 years.

That is an attack aircraft, although the Chinese army called it a fighter-bomber.

Right now, what Li Lu needs to wait for is news from Fang Hecheng's side. However, a week after he returned to the dry port, there was no news from Fang Hecheng, but the remaining four sets of five-axis linkage CNC machine tools from Toshiba arrived at the Red Star Factory.

This means that the logistics department of the military district accepted his proposal.

On this day, it happened to be New Year's Day, and Li Lu did not wait for news from Fang Hecheng, but waited for Lloyd of West German MBB Company. The main person in charge of MBB in Huaxia has not been heard from for more than a month.

Originally, Li Lu hoped to meet with Lloyd with Ma Jintao and Yao Taihang, but the result was that the arrival of the five-axis linkage CNC machine tool directly made these two masters enter a climactic state, and they couldn't wait to live in the zero workshop specially prepared for the five-axis linkage CNC machine tool.

I believe that at this time, even if Li Lu rushes, it will be difficult to drive Yao Taihang away. The emergence of five-axis linkage CNC machine tools means that the biggest problem of the S-7 aviation development project presided over by Yao Taihang has been completely solved - the processing of blades can meet the blade processing standards of Pratt & Whitney's JT3D engine, which means that the biggest problem affecting the life of the engine has been solved!

Pratt & Whitney's JT3D engine is the engine used in the subsequent modification of the Boeing 707, and the performance is more advanced than that of the earlier model, and the S-7 (apocryphal number) is developed by reference to the JT3D.

Although it is not easy to fully achieve the level of JT3D, it is completely feasible to reduce the gap at the technical level as much as possible in the current favorable international environment. Li Lu knows that the biggest defect of Huaxia Aviation Development is the same for decades - it is not that the technology is not advanced enough, but that the service life cannot meet the mass production standard.

What is a mass production standard?

For example, for fighter jets, the overhaul life of the aviation engine is required to reach 1,000 hours, that is to say, the engine can last for 1,000 hours before it needs to be overhauled, and for example, the engine used in civil airliners, if the overhaul life does not meet the minimum requirements, then there is no application value.

The P-series engines, as well as the earliest batch of S engines, could not even reach two hundred hours of overhaul life. There is simply no way for such a technical standard to be put into practical use. These refer to military standards.

Based on the JT3D turbofan engine, the military version of the turbofan engine TF33 has been widely used in a variety of models for a long time, relying on stability and a total life of more than 10,000 hours. The improved JT3D, produced by Pratt & Whitney a few years ago, is said to have a total life of 12,000 hours and a first overhaul life of more than 3,000 hours. Of course, military and civilian standards are completely different, and the life of civilian engines is much higher than that of military engines, which is the difference between the environment and the way they are used.

In fact, in the history of another time and space, the S-8 (the real historical number of the S-7) used by the Y10 airliner has not been able to solve the problem of longevity, and the blades are the key to it. The S-9, the domestic model of the Spey engine, began in the early 70s and was not completed until the end of the 20th century. You can imagine how critical the quality of the blades is. To make a good blade, there are two conditions that affect it - good materials and good processing technology.

At present, at least Li Lu has basically possessed these two basic conditions in his hands, especially the processing technology, the arrival of five-axis linkage CNC machine tools, so that the Red Star Factory has never had any research and development capabilities to become a domestic factory capable of processing qualified blades!

As we all know, the key to the life of the engine lies in the blades, and the better the blades, the longer the life.

Yao Taihang obviously knows very, very well what these two capabilities of the Red Star Factory means, especially the processing technology, he can almost see that after the finished product of the S-7, the first overhaul life can easily exceed 2,000 flight hours.

Don't talk about driving, if you put a knife on his neck now, he won't leave Workshop Zero half a step. He directly and simply demanded that the research institute be built next to workshop zero, and the project team of the S-7 aviation development would be placed there. Fortunately, there is some huge space in workshop zero, and all his requirements have been met.

This is the origin of the Red Star Factory Zero Research Institute.

After winning the S-7, the Red Star Plant has an absolute signature product - a mass-produced aviation turbofan engine with good versatility that can be used in military and civil aircraft. Li Lu really has no urgent expectations for whether the Y10 can be put into production.

The situation has changed, and now the Y10 is a research project of a private company, rather than a large aircraft project with political and military considerations. In other words, what Li Lu is thinking about is - who will sell this airliner to?

At present, the domestic air transport business is physically physique, and it is simply not possible to provide a qualified market, which will take time. Therefore, Li Lu is not in a hurry about this. However, the progress of the S-7 is very important to him. This heart is very important.

The intention to cooperate with West German MBB to develop a 100-seater passenger aircraft is different from that of the Y10, because it is developed in cooperation with West German MBB, and Li Lu does not have to worry too much about sales. The purpose of making a passenger plane is to sell, that is, to make money, and if this purpose is not achieved, no enterprise will do it, unless there are national factors behind it, even if there is a lot of loss.

Therefore, for different considerations, Li Lu and Yao Taihang have the same view, and agree that the focus should be on the research and development of the S-7 aviation engine, while the other sub-projects of the Y10 can be appropriately slowed down.

In stark contrast, Li Lu attached great importance to Lloyd's arrival. So much so that he did not participate in the celebration of New Year's Day at the Red Star Factory, and rushed to the seaside guest house to meet with Lloyd. Since the conditional opening of this guest house of the municipal party committee to the outside world, it has been frequented by either the people of the Red Star Factory or the customers of the Red Star Factory, and of course, there are also many customers of the Red Star Defense Company.

More than a month apart, Lloyd obviously received clear instructions from the upper echelons of MBB, and this meeting with Li Lu is definitely no longer the previous meeting with obvious intentions.

Sure enough, at around ten o'clock in the morning, when Li Lu met Lloyd in the third building of the waterfront guest house, he brought a team of five members, including him.

Seeing Lloyd's confident smile, Li Lu suddenly had an idea - what kind of situation would it be if the 100-seat passenger plane developed in cooperation with MBB could be equipped with S-7 engines?

Maybe the world's aviation community will be shocked by this, right?
