#517 - Copy small thrust engine
With the chip design opening up new avenues, Ren Zhong turned his attention to a new field.
The aviation industry now possesses a generational advantage over the Liangjian World.
There is much to be gained in this field as well.
"Professor An, it's a pleasure to meet you!" After some searching, Ren Zhong found An Shao Chen, the chief professor at a certain aeronautical university who researches engines. Professor An has participated in the design of several mainstream turbofan engines in China.
He is a true leading figure in domestic aviation engine design, and his relationship with the chief engineers of several aviation engine companies is almost like that of fellow disciples.
The difference is that Professor An is engaged in both scientific research and teaching, constantly supplying Dongda University with aviation engine talent.
He has several doctoral and master's student teams under his command.
"Boss Ren, hello!" In contrast to Ren Zhong's enthusiasm, Professor An was somewhat indifferent to Ren Zhong.
"I heard that Boss Ren wants to entrust us with the development of a turbofan engine. I wonder what the specifics are? What are the specifications of this aviation engine?"
Professor An got straight to the point.
"Professor An, we want to enter the long-range drone industry, so we need an excellent turbofan engine. After our initial screening, our team of experts believes that the HTF7000 small turbofan engine is quite good. We hope to first imitate and develop a similar product based on this engine as a prototype, and then, on this basis, the team will redesign a completely independent and controllable new turbofan engine. I wonder if Professor An's side has any difficulties?" Ren Zhong put forward his long-considered idea.
He couldn't come up with any good ideas by directly stating the specifications, so he felt that iterating on a successful product was the most reliable approach.
The HTF7000 is a famous engine from Honeywell, widely used in the famous Bombardier Challenger 300 and 500 series business jets, as well as the Gulfstream 280 series, and the Embraer Legacy 500 and 450 series. In terms of specifications, the HTF7000 turbofan engine has a length of 2.29 meters; a fan diameter of 0.87 meters; a weight of 620 kilograms; and a maximum thrust of 7638 lbf (34kN).
It is small and exquisite, with excellent power and fuel consumption. It is the first choice for business jets in the main world, and several of Zhu Min's business jets are equipped with it. However, in Ren Zhong's view, this aviation engine is more suitable for drones, and it is one of the excellent power sources for long-range drones.
In the main world, the Bombardier Challenger 300 business jet, which uses this engine, achieves a maximum range of 5741 kilometers and has the ability to fly across continents, with a maximum cruising speed of 870 kilometers per hour.
It can be said to be quite excellent. If such an aviation engine is introduced into the Liangjian World, then with the aircraft design capabilities of the Liangjian World, it is entirely possible to realize a reconnaissance aircraft with performance similar to the Bombardier Challenger 300, undertaking the main force of aerial reconnaissance.
Compared with the Yun-6 and Yun-8 reconnaissance aircraft, which are currently the main force in the Liangjian World, the technology has been greatly improved. Both in terms of speed and range, it is far ahead.
It's not that there are no aviation engines stronger than this in the main world, but unfortunately, not to mention that Ren Zhong can't get top-notch aviation engines, I'm afraid that even top professors like Professor An can't get them, or dare not get them.
For example, the famous WS-10 C, WS-13 C, and WS-19 B three series of turbofan engines are all top secrets.
"Boss Ren, the protection of intellectual property rights in today's society is very complete. There is almost no commercial value in choosing to copy such a product. Wouldn't it be better if we directly redesigned a similar aviation engine?" Professor An frowned, without saying whether the HTF7000 could be copied. Obviously, he was very confident in his ability and didn't want to copy an existing aviation engine.
Of course, this was a pie that Ren Zhong drew to find a reason for his research on a small turbofan engine.
Now the joint military-civilian construction of the main world is relatively mature. There are quite a few wealthy people like Ren Zhong who have some money on hand and want to engage in something new. Professor An didn't think too much about it and regarded this project as a purely horizontal project to earn some extra money for the research group. Now, being able to take on a deal with an investment of over 100 million is not a small amount for Professor An.
The appropriation he received from above was not this much, and this was still a real complete machine research and development, which was also a test for his team.
Fortunately, Professor An's fellow disciples and grand-disciples are all over the aviation engine field of Dongda University. If some majors are really not good, he can also borrow the corresponding experts to help solve them. With hundreds of millions of funds in his hand, he is not afraid of not being able to afford this expense.
Ren Zhong also wanted to engage in high thrust, but high thrust was too sensitive. As a private entrepreneur, engaging in a military aviation engine always felt strange, because everyone knew very well that Dongda University's military high thrust would never be used in the models produced by civil aviation engine companies.
Unless there is a real design genius who can improve civil aviation engine technology to be one generation ahead of the state-owned enterprise, but this is impossible.
Now, the private aviation team of Dongda University will never be able to defeat the national team.
A small turbofan engine with over 30 kilonewtons of thrust is a very good entry point. This thrust is not only suitable for large and medium-sized business jets, but more importantly, after being modified into a small bypass ratio engine based on the core engine, the new small bypass ratio turbofan engine in the Bright Sword world is very suitable for replacing early turbojet engines as the power for trainer aircraft and light fighter jets.
For the Bright Sword world, it is still too early to develop drones. The current computer systems basically do not support such computing power applications. Relatively speaking, communication is also a considerable problem. The current satellite communication bandwidth and wireless communication capabilities are also insufficient to support drone aerial communication spanning thousands of kilometers.
It can be said that communication alone is a major obstacle that the Bright Sword world can hardly overcome.
Originally, the trainer aircraft based on the FTG2000 prototype can now be modified into a third-generation fighter trainer aircraft based on the L-15 prototype with this new turbofan engine improved from the HTF7000. The overall performance will be further improved, with the greatest performance improvement being the trainer's maximum cruising speed and maneuverability.
Although some thrust is slightly lost after modifying the HTF7000 into a small bypass ratio, for a light trainer aircraft that is mainly for training and secondarily for combat, two 30KN turbofan engines can be considered fuel-efficient and powerful. From a configuration point of view, it is still much better than directly using a WS-9.
The original FTG2000 used a single turbojet - 13F engine with only forty-odd kilonewtons of thrust. Replacing it with this improved small turbofan engine in a twin-engine design immediately increases the overall power. Although 60KN of power makes it somewhat difficult to break through Mach 2, breaking through Mach 1.5 is not a big problem. Compared to the Falcon, the real third-generation trainer aircraft of Dongda in the main world, it is not far behind, and in the Bright Sword world, it is far ahead.
According to Ren Zhong's plan, the export version of Dongda's light fighter jet can be further deeply improved on this trainer aircraft. After installing a radar avionics system with stronger power, it can be used as the main fighter jet for small countries.
At least when facing propeller fighters, it is a complete crushing victory. Even when facing the first and second generation turbojet fighter jets of the Bright Sword world today, it is still a notch better.
In small countries, it can be completely used as the main fighter jet.
As long as Ren Zhong obtains the complete set of counterfeit technology data for the HTF7000, the 100 million yuan of research and development costs invested will be a huge profit. It is not very eye-catching in the main world, but it must be top-notch in the Bright Sword world.
It just so happens that he can use this thing to make Rolls-Royce look at him with new eyes. No matter how they guess, this small turbofan engine is a stunning product in the era of the Bright Sword world.
According to the current plan, Rolls-Royce in the Bright Sword world is deeply tied to the aviation development of Dongda. A vertical take-off and landing engine, a large three-rotor passenger aircraft aero engine, and an enhanced version of the WS-9 engine. It can be said that Rolls-Royce is doing its best to cooperate with Dongda to do a good job in aero engines.
The latest novels are first published on Liu 9 Shu Ba!
Therefore, after obtaining this engine, Dongda Aviation in the Bright Sword world will once again shock Rolls-Royce, which is obviously very beneficial for the next technical cooperation work.
When you have more advanced things in your hands, the opponent's cooperation with you is awe-inspiring with a bit of gratitude. Even if the thrust of this aero engine is a little smaller, it is enough to be technically advanced.
Now that the complementary research and development systems of the two worlds have been realized, Ren Zhong's plan is even more executable.
Spending money in the main world and launching heavy punches in the Bright Sword world, this model is indeed very refreshing.
In terms of entry points, a new world has now been opened up. According to this model, Ren Zhong is looking for the strongest disciplines in various universities to donate equipment and provide horizontal projects.
Of course, there will be no such large-scale investment as the School of Electronic Engineering. It is enough to play this kind of investment in the School of Electronic Engineering. Ren Zhong can't bear it if there is more.
In the School of Electronic Engineering, 800 million yuan has been invested in equipment alone. In addition to the research projects that followed, plus the purchase of the ARM full series of complete data, even if it was a clever approach, it cost a little less than 10 million soft sister coins.
Of course, the ARM2 basic chip that Ren Zhong brought back to the Bright Sword world can be processed and is ready to completely replace 8080 and 8086 in industrial control applications.
On the other hand, Ren Zhong has obtained several radar-related function algorithm DSP design drawings. These dedicated algorithm DSP structures are relatively simple, and the circuits are not very developed, so the Bright Sword world can also process them now. This is after cooperating with the School of Electronic Engineering, Ren Zhong's ability to obtain these data has been greatly improved.
Although the professors of the School of Electronic Engineering do not know what Ren Zhong is doing with these algorithmic DSPs, these things are basic models and are no longer a secret, so they directly give them to Ren Zhong to play with.
However, for the people of the Bright Sword world, these DSPs have opened up a new world for them. For application scenarios such as radar, the computational complexity and calculation speed have increased by orders of magnitude, which greatly improves the technical level of radar design in the Bright Sword world!
Whether it is from reaction speed, positioning accuracy, or maximum effective range and other key indicators, there has been rapid progress.
Originally, some stagnant Doppler radars have now begun to show rapid progress due to the increase in computing power by orders of magnitude, and many calculations have support.
According to the project team's estimates, the breakthrough of the first generation of Doppler multi-function radar will be within this year.
Ren Zhong is naturally very pleased with this effect. After all, before, the material data and principle data were given to the project team. They have made relatively smooth progress in this area. The only problem is that the current 8086 chips are not strong enough in terms of computing power. The reaction time for running the algorithm far exceeds the chip's capabilities, so the accuracy and reaction speed are not very ideal.
When they started developing hardware DSPs to do algorithms, the overall computing efficiency increased by more than an order of magnitude, and the technical bottleneck in radar filtering and other aspects in the Bright Sword world was broken at once.
Ren Zhong's wave of large-scale investment in the main world has not yet made any progress in chip processing technology, but it has already begun to see results in other aspects.
The introduction of ARM chips and DSP chips has greatly improved the radar computing level at once, laying a new computing power foundation for the advent of a new generation of radars.
The complete equipment configuration and the principles, basic shapes, main performance parameters, etc. of the new generation of chip processing production lines are now also constantly entering the Bright Sword world, providing reference for Dongda's chip equipment manufacturing industry.
With such a complete technical route development guide, how many years of detours will Dongda's semiconductor equipment manufacturing industry, which has no experience at all, have to take to reach this day.
The chip and the aviation industry seem to have miraculously activated the process of mutual integration, and the digitization of aviation equipment is moving further and further away with the introduction of ARM chips.
Aviation avionics and engines, these cutting-edge equipment, will eventually be fully digitalized. Therefore, after Dongda takes this step, breakthroughs in aviation avionics and engines are not far away.
