Chapter 1532: Route dispute (4)

What is Song Wenhua's idea, Tan Er is too clear in his heart, but he has his own arrangements and plans for this-not to mention whether the Yakovlev Design Bureau is willing or not to give something, just at this time China In terms of simply digesting and absorbing this batch of good things brought back, we need to invest a lot of manpower and material resources. With China's current resources and talent reserves, to rashly open a new front, the timing may not be right.
So Tan Zhenhua had to pretend that he didn’t see the teacher’s gaze, and followed Wu Daguan’s topic: "Mr. Zhang, don’t worry too much about the progress. Actually, you don’t have to watch this R- 79. This engine is actually the product of the failure of the Tumansky Design Bureau to compete with the AL41F of the Lulica Design Bureau for the MiG 1.44 fighter engine. I have seen the basic parameters of this engine, and its thrust can reach 15.5 tons, but it was obtained at a great price. Its thrust-to-weight ratio is only 5.64. This data can't even reach the thrust-to-weight ratio data of the US's third-generation aeroengine of 7 or more, and its front turbine temperature is only At 1620K, it is far from the current level of turbine temperature above 1800K for advanced US aviation development. Judging from my limited aviation development knowledge, the reference significance of R-79 is far greater than the actual engineering significance."
"Then how much air flow does its core machine have?"
"138 kilograms per second." Wu Daguan replied.
After a quick mental calculation, Zhang Enhe couldn't help but sighed secretly. The core engine of the "Turbofan 10" he is now in charge of has borrowed heavily from the technology of the classic civil aviation engine model CFM56, and the core engine of CFM56 comes from General Motors Corporation of America. According to the basic principles of aviation, the greater the air flow of the core engine, the greater the thrust when other conditions are the same-in other words, the air flow of this core machine is 120 kilograms per second. Once the -79 is successfully developed, its thrust will definitely be greater than that of the "Turbofan 10"!
With a more promising development direction, and the opponent is a guy with so much money that I don’t know how to describe it, will the country...
Wu Daguan saw a clue from Zhang Enhe’s face, and couldn’t help but smile and said,
Xiao Zhang, don’t worry, Minister Zhang is here. I have discussed this matter with him in detail,
Turbofan 10" This project will not stop or stop, and not only will it not stop, the Ministry has also decided to increase investment and strive to get it out as quickly as possible. What about Dr. Tan? We plan to go completely positive this time. R-79 is just a reference and reference for the way of research and development. The goal is to achieve a push-to-weight ratio of 9 or even break through 10. This will face more difficulties and tests. Besides, we all know that for Hangfa, Materials and processing technology are a major hurdle that we cannot overcome. These most basic research results, whether it is for your "Turbofan 10" or for Dr. Tan’s new release, will provide the same help and openly. However, Lao Song’s "J-10" has begun to manufacture its first prototype. Although it has been decided to use Rakshasa’s "AL-31F" as the first flight power, the target engine is still your "turbofan 10". The main fighter of our Air Force in the future, of course, cannot always use foreign engines. You have to refuel."
The speech was half-hearted, with encouragement and pressure. This is Wu Daguan. Besides him, in China's aviation industry, who is qualified to speak to Zhang Enhe like this, how many can he find?
Zhang Enhe, who knows that the project is intact, can be considered to have let go of half of his thoughts-he was also frustrated by the kind of decision-making method that projects recklessly in the past few years. Think about it. I slap my head and I will stop it when I say stop. Who can stand this?
And doing scientific research with this mindset will inevitably be half-hearted, isn't it?
However, Wu Daguan's last few words of encouragement and spurring made him blush, and he wanted to say a few words of merit and determination, but Minister Zhang was the first to speak: "The development of aviation engines You need to calm down and make progress step by step. Mr. Zhang should not put too much pressure on yourself. A good meal is not afraid of late. Now that there is a solution to the engine problem of the "J-10", you still have to keep improving, and you must not be greedy. Okay, let’s stop here for the time being about the big push. The three lines go hand in hand, so we have more guarantees. Next, let’s talk about the middle push."
"Zhongtui, we now have at least two technical routes." This time it was Liu Daxiang of the Gas Turbine Institute.
"The one that is mature and usable is the "Huashan" engine that we developed in cooperation with Rolls-Royce, and was finalized as "Turbofan 7" after national acceptance. The engine is developed based on the "Speey MK807" and has a maximum thrust of 8.25 tons. Due to the use of a large number of new materials, the thrust-to-weight ratio has reached 6.25, and it has now been adopted by the "Fierce Dragon" fighters exported to Pakistan Railway. At the same time, after seeing this type of fighter, the Air Force believes that under the current situation, it can also be used in China. A batch is equipped to replace some of the "F-6" and "Strong 5" fighters that are still in service. Therefore, we can expect that the production and sales of this type of engine will be very large, and the total number of equipment is expected to exceed 2,000."
As soon as this number was reported, the faces of several related units were intertwined with pride and excitement. Among them, the most proud of them were of course the Xihangfa and Rongcheng Aircraft Factory attending the meeting.
Especially Song Wenhua, at this time, he involuntarily appeared in his mind when the outline of the "Fierce Dragon" fighter was sketched on a napkin for the first time, and a smile appeared involuntarily at the corner of his mouth.
The "Xiaolong" fighter was born out of the "Jiqi". At the beginning, it was called the "Almighty Super 7" by Tan Zhenhua. It was originally developed to meet the needs of Pakistan Railways as a major export modification. "J-7" can be done in Bende, West Air Development and Gas Turbine Institute jointly completed the "Turbofan 7", he himself fixed the aerodynamic shape of the large wing and worked with Chen Yijian to fix the redundant telex After the flight control, this type of fighter was completely reborn and developed into a true third-generation fighter. Now even if Artem Mikoyan and Mikhail Gurevich are reborn, I am afraid they will not be seen. What is the blood relationship between this fighter and the "MiG 21".
After a series of successful improvements, the "Fierce Dragon" fighters have begun to be delivered to the Pakistan Railway Air Force one after another, and in the exercises organized by the country, they have fought against the F-16 many times and achieved an exchange ratio of about 0.8:1. This successfully attracted the attention of the Huaxia Air Force. At this time, the Huaxia Air Force, except for the Su-27, which had not yet formed a combat capability at the beginning, had not been able to carry out beyond the visual range. The third-generation fighters of the air combat, because of the "Flying Leopards", they finally just lined up, and even the first regiment is not full, and the "J-8 II" that was once high hopes has now been seen. The air and navy armies dislike it too much...
China Xia once manufactured 5,205 "J-6" aircraft. Except for the export of less than 1,000, the rest are for self-use. More than 3,000 aircraft are owned by the Air Force. Although since the early 1980s, the "J-7" and "J-7" have been used. The eight" is gradually replaced, but the current number of in service still exceeds 2,000. In fact, in another time and space, the date of retirement of China's last "J-6" is-June 12, 2010!
There are more than 2,000 "J-6"s that need to be eliminated. The number of replacements for this new aircraft is really impressive. Both the "Su-27" and the "Flying Leopard" are dual-engine heavy fighters, and the cost of equipment and use are real. It’s too expensive. If you want to use this kind of fighters to replace the amazingly equipped "J-6", it is not what China's current national strength can do. According to the original plan, these aircraft will be built to be "J-7" and "J-8". "Replace, but now that there is a better choice, the Air and Sea forces naturally hit the "Fierce Dragon" of the 3611 Institute, using China's current capabilities in various aspects to replace the subsequent ones with "Fierce Dragon" fighters. Organization, not only can greatly improve the combat power of the Air Force, but also is the best cost-effective and cost-effective solution!
Ever since, the smile on Song Wenhua's face was getting more and more every day, and even the look in Tan Er's eyes became more and more cordial.
