The fate of the turbofan eight is closely related to Yun Shi, and the two are complementary to each other. In a series of research and development, both the turbofan 8 and the 10 were in danger of being dismounted because of low results or too high costs. But in this world, both are still safe, and the performance of the project is a little better. Although this is a little bit, it can also make the sensitive Liu Fei feel that this project is really not the original project.

Common.. And.. One of the characteristics of the country is that the supporting engine is always developed after the aircraft project is established, and only one engine is equipped with an aircraft, which has caused a great waste of resources. But there's nothing that can be done, after all, this is not something that Liu Fei can directly change alone, Liu Fei can get a company that has already been borrowed. The spring breeze of the revolution is open, if you don't have long glasses, in the human society.. It would be a death.

Liu Fei can only sweep the snow in front of the door well now, and make his development path better, so that he can have a greater impact on the total.. And.. The development of the country's military industry can make the Communist Party .. And.. The kingdom was soon to achieve the great revival that had been dreamed of for several lifetimes.

The aviation industry is definitely a profiteering industry, so Liu Fei must take seriously the cornucopia he has now.

Turbofan 8 is an imitation of Pratt & Whitney JT-3D, but what Liu Fei needs is not this kind of "leaky turbojet" that has been behind for I don't know how many years. This is a turbofan engine that was finalized and produced in the fifties and sixties, and the bypass ratio is pitiful. Major customers such as the Boeing 707 and CovnairDash70 have modernized their engines with the more cost-effective CFM56.

This kind of "leakage turbojet" that can be deflated intermittently or uninterruptedly is not what Liu Fei wants, because the indicators of these engines have not been able to keep up with the big development trend, especially in terms of fuel consumption and noise. These two are definitely hard injuries, and as for the thrust, they can bear it, because now they can't make a super-large long-range wide-body passenger aircraft with the existing industry of the rabbit, even if the thrust is very large, it has no effect.

Liu Fei found the team of Turbofan 8, which can be regarded as finding very powerful talents in China. Even the people who are engaged in Spey engines have been transferred to a few in order to be able to develop better domestic large aircraft engines.

It is a great achievement to be able to localize the engine of a large aircraft!

Liu Fei is holding his own modified PJT9D The failure rate is relatively high, but it is the world's first large-bypass turbofan engine, because the technology is relatively primitive, it is more suitable for the aviation industry that has just begun to awaken.

Civil aero engines don't need to be so powerful, and what is the afterburner, as long as the civil aero engine can ensure safety. Therefore, what Liu Fei needs to ensure is that the durability of the aero engine must be high, and the JT-9D was not without problems when it was just produced, mainly because there was a problem with the shell of the engine, so it would often explode directly.

When the Boeing 747 was first produced, this engine was very criticized - the safety of new things is always bad - so the test pilot directly pulled Prad ※※※

Now that Liu Fei's design scheme has been optimized, it is natural that it will not be so white. Crazy problem, this is the first generation of large bypass ratio turbofan engine, Liu Fei naturally believes that the flower industry that has been producing low bypass ratio engines will be able to convert.

If it can't be converted, Liu Fei needs to strengthen the industry. Otherwise, how can it continue to develop. The airliners below were all large bypass ratio engines, and small bypass ratio engines only existed during the time when jet aircraft were just beginning to emerge.

The large bypass ratio engine can reduce noise, which is very important, and the fan can generate additional power, and the suppression of high-speed airflow through high velocity would otherwise be present in the spray. The loud noise in the jet stream is commendable. The reason why the turbofan engine is less noisy is because the extra air of the fan blocks the transmission of these noises.

……

Although the current domestic materials are simply incomparable with the later 919 when they went to the sky, don't forget that the foreign materials are not much better now! Therefore, the team of turbofan eight quickly got the turbofan engine of the large aircraft that Liu Fei dreamed of, and the engine with a large bypass ratio made everyone see hope, the military project of this engine was S-8, but Liu Fei asked the military to change the project to S-8-O-8820, and unfolded it that is, "turbofan engine-8-prototype-20,000kgf level", and later S-8 was also broken by Liu Fei. In the end, even when Liu Fei saw a retired turbofan of the eighth prototype, he was asking which engine it was, and why did it look so familiar.

Liu Fei personally escorted five turbofan eight to the aircraft assembly plant in Modu, where the Y-10 will complete the final step of localization. In the previous has been installed is the "foreign heart" of the Yun ten, from today, finally has a strong... Healthy's "in.. National Heart"!

When the Big Mac flew up with a long stream of black smoke, the eyes of many of the older generation of aviation people were full of tears.

This is the first big plane, a completely domestic big plane!

Even the avionics equipment that originally needed to be imported was also used at Liu Fei's insistence on the slightly backward electro-mechanical hybrid type, and now it seems that the test flight should be very successful, so it should not be long before the Yun-10 can officially start to be sold.

Even if it can't be sold beautifully... The capital of the country and so on. Yoshikook.. Go home, at least the society.. Host: The righteous camp can still be sold. Especially such a high-performance aircraft, the company.. Host: The old inside the righteous camp. Hair.. There is no such high cost performance!

……

The turbofan eight soon attracted the attention of the world, and the rabbit made such a thing and was quickly known, especially the mother's family Puhui of this engine hurriedly began to study, Liu Fei's engine is nominal 20,000kgf, which is 44,052.8lbf. Although this figure is not as good as the 46,300lbf to 50,000lbf output of the genuine JT-9D, at high altitude, this thing can be completely ignored!

However, Liu Fei doesn't care about these people, and now Chief Engineer Ma gave Liu Fei an improvement plan, the plan is mainly to enlarge the fuselage, so that the fuselage can reach a capacity of 280~360 passengers. In this way, Yun Shi can be stronger as a rising star. Hard confidence to compete.
