Chapter 1143: Engine with a thrust-to-weight ratio of 10

Whether it is a surveying and mapping copying, or self-developed, etc., as long as it has, the country will no longer waste funds, and the technology of the big push is complicated and not so easy to obtain.
In this case, the research has just found a blank breakthrough.
Large domestic units and key units are engaged in large-scale pushes, but no one is involved in the middle- pushes, and the middle- pushes happen to have hit targets.
For example, the domestically produced F-14 fighter jets have always been subject to export because they do not have suitable engines. If they have an engine, then there is no need to look at the faces of the Eagles, and they can be exported to more countries!
This was a breakthrough they aimed at, and Qin Guan thought more.
Once Zhongtui is developed, it is not just for the F-14.
The J-8 can also be used. Now President Gu has been equipping their J-8 with the RB199. Doesn't he want to have more advanced combat effectiveness?
The domestic air force will certainly not look down on this kind of goods, but there will definitely be big money owners abroad to buy it.
With this turbofan engine, the range will be longer and the acceleration will be better. Maybe the performance can really be improved effectively. At the same time, it can also reserve power for the future.
What's next?
Of course, it is the future UAV. In later generations, UAVs will become popular. The power required by UAVs is exactly the category of this kind of push. It can be said that the development of a middle push has the meaning Considerable.
Let’s talk about it now.
"Although we intend to refer to the mainstream engines F404 and RB199 at the time, we do not intend to find a copy of the reference like other engines. We have to completely self-research, such as the 7 stage compressor. We will start from the first stage. Increase at the first level, study at the first level, and truly master the technology."
This idea of ​​Kang Elder made everyone very admired. Qin Guan also gave a thumbs up. That's right, if you really do this, you can really master the technology completely, unlike the way we are now. It is not easy to modify the whole body.
The turbofan-12 in history is indeed such a project. It has been studied level by level and is the only compressor that is truly mastered.
For another example, its short burst diffuser ultra-compact annular combustion chamber is inspired by research on RB199, which is nearly half shorter than the F404 combustion chamber. The three-stage fan design is closer to 404, but the parameters are completely different.
In short, the final WS12 overall design parameters are reasonable, three-stage low aspect ratio shoulderless fan, seven-stage compressor, high-low pressure turbine each stage, engine bypass ratio of about 0.5, about 4000 mm in length, fan inlet 880mm, engine The maximum diameter is about 1 meter, the total boost ratio is 23, the temperature before the turbine is 1600K, the maximum military thrust is 5300 kg, the maximum thrust is 8700 kg, and the engine weighs 1080 kg.
It can be said that this engine has finally reached an order of magnitude of the M88. Unfortunately, this engine was finally dismounted because there was no target for installation. Instead, a surveying and mapping copy of the RD93 engine was developed, and the technical indicators have all gone backwards. It's so embarrassing.
Historically, this project started in the late 1980s, but now, thanks to the promotion of Qin Guan, domestic aviation research has made great progress. Even if the country’s funds are limited, the horizons have been broadened. Go along the right path.
"By the way, Elder Kang, you just said that the current 6624 institute has also begun to adopt the contract system and contract system, right?" Qin Guan asked.
Qin Guan suddenly asked a question like this. Elder Kang was suddenly surprised. He didn't know what he wanted to say, and nodded, "Yes, that's it."
"In this case, can we also participate in the North Industries Corporation?" Qin Guan said: "We will inject capital into this project and also get certain shares, how about?"
Hearing what he said, Elder Kang and others were overjoyed.
The biggest shortcoming of their pre-research project is the lack of funds. The project may end due to lack of funds at any time. After all, the country’s funds are insufficient, and the development of engines is the most expensive.
North Industries Corporation, in a series of foreign arms sales, has already made a lot of money. If they provide funds, they will definitely be able to continue the project!
"Of course it can. If so, that would be great." Kang said, "It's a pity that our research institute is state-owned, otherwise you can buy our company."
If you can become a subsidiary of the North Industries Corporation, then you will no longer have to worry about funds when you develop. If you are backed by the North Industries Corporation, you will not be afraid of anything.
Qin Guan shook his head: "No, let's inject capital. We promise that within ten years, we will inject 100 million in capital and occupy 20% of the shares in this project. How about?"
One hundred million, which is almost enough for all the R&D expenses. Hearing what Qin Guan said, Elder Kang was even more happy: "Of course that would be great!"
Researching the engine is very expensive, and doing an experiment will cost a lot of money. In the past, it was all about reporting and approving to the superior, and the experiment could only be done after approval.
Now that I have money, I can spend it energetically. Ten million a year, do whatever experiment you want.
"However, I have a requirement." Qin Guan said: "Our index needs to be improved a bit, and we should aim for an engine with a thrust-to-weight ratio of 10."
Hearing this, everyone was taken aback, right? Who can achieve this indicator?
Of course, Qin Guan knew that this goal was advanced. According to the plan of the 6624 Institute, the turbofan-12, which is similar to the F404 engine, is already very bad.
But if that is the case, what are the advantages of your own system?
According to Qin Guan's plan, in the 1990s, domestic advanced fourth-generation fighter jets will appear, and this fighter jet should catch up to the level of the West.
Pre-research is about to begin now.
On the third-generation machine, our side has caught up. Although the engine still has problems, with the efforts of the 4430 factory, the third-generation big push will definitely be able to come out. As the turbine research institute, the 6624 institute should play a pre-research role. , Three generations of engines already exist, why are they still doing pre-research? It is the fourth-generation engine to pre-research.
As for the middle push they plan to engage in, they already have a plan and hand it over to the 4460 factory. If they do it again, it is repetitive. Anyway, it is the pre-research. Let's set the target higher now.
"Everyone finds it difficult. Ten years will not work. Then fifteen years. In short, this index cannot be changed. How about a push-to-weight ratio of 10? Do you think it is exaggerated?" Qin looked at the faces of everyone and knew everyone. Still unwilling to believe it.
"However, we can't wait any longer. We want to target the Eagle National ATF plan!"
