Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 99 Qin Liang's Deep Schemes

The Air Force felt that using four Spey engines at once was too expensive. They only considered the purchase price, not the overall cost of use. The savings in fuel, maintenance time, and engine replacement costs over the entire lifespan of four Spey engines were definitely much greater than those of two WP-8 turbojet engines!
Unfortunately, the Air Force doesn't care about these things. In the Air Force's eyes, high procurement costs are unacceptable!

Now things are much better. Qin Liang has proposed an improvement plan for the Spey, which increases the bypass ratio and thrust. When it reaches about ten tons, it will be perfect for modifying the H-6 bomber. Only two of them will be needed. The Air Force should have no objections now, right?
Moreover, this thrust engine is a perfect match for the Y-10 project. As a result, Spey will have more installation targets, which will give it strong support from higher authorities and reduce opposition.

Thinking of this, Old Wu became even more excited.

"No, no, that's impossible. You know so much about engines, so you should know that changing fan blades is not simple, especially with the bypass ratio increased by three times. This requires a significant increase in the power driving the fan, which means that the turbine output needs to be increased. This is almost equivalent to a complete redesign."

If it were an advanced engine, a redesign would be acceptable, but the Spey is already an outdated and obsolete product for Rolls-Royce. There's no need to put effort into such a product; it would be a complete waste of time!

"However, if we use the existing structure, it would be a waste to modify it with brand new fan blades. How about we try something different and modify your most advanced engine? Just send us a copy of the engine's technical data, and we'll design the fan blades."

Hand it over to you? Are you kidding me? I can only give you outdated technology; advanced technology is absolutely out of the question!

Schroeder and the others were speechless.

"How about this, we can design the new turbine blades here, and we can use our advanced single-crystal blades. This will raise the turbine inlet temperature by about 100 degrees, further increasing the engine's thrust."

"What? You have advanced single-crystal blades that can increase the temperature by about 100 degrees?"

The British were even more astonished. Wasn't Eastern technology supposed to be backward? How could so many advanced technologies suddenly emerge? There were advanced single-crystal turbine blades, even better than those used on the Spey, and advanced fan blade technology…

"An increase of about a hundred degrees is a conservative estimate; in reality, it can be increased even more." Qin Liang smiled. "It would be a waste to use these turbine blades only on turbojet engines. Let's modify the Spey. Gentlemen, are you interested?"

Schroeder took a deep breath: "Okay, we can modify it in the East, but... modifying an engine is not simple; it requires a lot of calculations, and without advanced computers..."

"Have!"

Qin Liang nodded: "Everyone can come to our Northwestern Polytechnical University, and we can complete the calculations for the Spey modification together!"

Northwestern Polytechnical University?

"Yes, Northwestern Polytechnical University. Let me introduce myself. I am a student at Northwestern Polytechnical University and I just started my freshman year this year."

Northwestern Polytechnical University.

During the winter break, the campus became very quiet, with only a few students who stayed on campus passing by in a hurry.

In the computer room of Department 5, however, the scene was quite different. Everyone was staring intently at their computers, watching the characters on the screens, which captivated their attention.

"For the finite element method, we still need to use a computer. The machine head will be able to complete all the calculations soon!"

"Yeah, this calculation speed is faster than all of us combined in a year! We'll definitely finish the task on time and won't let Qin Liang down. By the way, where's Qin Liang? We haven't seen him for so long."

After assigning them tasks, Qin Liang left. They had been so busy with work that they had almost forgotten about him. Now, seeing their work achieving some progress, they remembered him again. Subconsciously, they had come to regard him as their leader. Professor Sha and Professor Liu were also absent; they had gone to Factory 132 to work on the Super 7 project. The teacher leading the team in the machine room was Yu Zhi. Hearing the discussion, Yu Zhi looked up and said, "Students, Qin Liang has gone to do even more important work. Everyone should work hard and strive to be like him as soon as possible..."

Boom!
The door opened, and Zhao Xiaoxia exclaimed excitedly, "Qin Liang is back! He brought a few foreigners with him! Everyone, get ready and make room for Qin Liang to use a computer!"

came back!
Qin Liang sighed inwardly. Every time he went out, he never knew what special circumstances he would encounter. He was supposed to go to the capital for a meeting, but he ended up going abroad!
Fortunately, this was just a stop on the way to Factory 430, and I managed to fool them a little.

"Mr. Schroeder, look, this is the computer at our Northwestern Polytechnical University."

"An IBM S/370 computer? The top-of-the-line one? How could such a computer possibly appear in your East?" Schroeder stared at the computer, his eyes wide. "Even our Rolls-Royce only installed a batch of these computers last year!"

"This is the strength of Northwestern Polytechnical University," Qin Liang said. "Everyone, using this computer, we can design the turbine blades for the Spey in the shortest time, and leave the subsequent debugging to us."

Aero engines require complex knowledge of fluid dynamics, which cannot often be calculated by computers. They still need to be tested in practice and continuously modified. However, as computer computing power has become stronger, computer-aided design has become more and more effective, especially since it does not involve the compressor and only the turbine blades, which are not very difficult.

Schroeder nodded: "Okay, but... we have one more request."

"please say."

"You need to hand over this advanced single-crystal turbine blade technology to us!"

Old Wu, who was accompanying them, changed his expression. These foreigners were truly insatiable!
"Okay, no problem!" Qin Liang replied readily.

"Alright, everyone, let's get to work! From now on, this computer is yours!"

Schroeder looked around: "Can we clear out this server room? We can't let others see our technology!"

"That's impossible. The other computers are still doing other important work. Let's set up a cordon. We won't look at yours, and you can't look at ours either," Qin Liang said.

The British were also very serious and responsible. They got right to work and within minutes they were engrossed in their tasks. Mr. Wu watched for a while before reluctantly leaving and going to a nearby office.

"Qin Liang, you promised to hand over our advanced turbine blade technology to them, won't that..."

"I only said I'd give it to them, not that I'd give it to them. They'll definitely have to pay for it, or maybe there are some problems with the process we gave them, and we haven't fully figured it out yet..."

Old Wu's eyes widened. For an honest person like him, it was impossible to think so much. He didn't know there were so many tricks involved. It was all thanks to Qin Liang!
"Sigh, what a pity, they won't let us see. If only we knew how they designed it..."

"There's no need to rush. There's a secret program in the computer that will record their research process in its entirety."
