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

Chapter 121 Spey is a treasure

Chang'an Airport.

"Qin Liang, thank you so much for taking us abroad," Tang Changhong said. "Having witnessed the prosperity of the West, we feel an even stronger sense of urgency..."

"Ahem, the British paid for the shopping and the plane tickets for Lao Ba's trip. I didn't do anything... By the way, we brought back quite a lot of stuff this time. We'll divide it up when we get back. We can put that color TV in our 5381 classroom."

"Qin Liang, do you want to put the TV in your father's dorm room? He..."

"If he knew I bought him a TV, he'd probably scold me for wasting money. The TV will be in our classroom; it'll be useful for organizing activities and such..."

As they were speaking, two men in green shirts and blue pants walked over: "Comrade Qin Liang, please come with us!"

Okay, something else has come up!
Qin Liang took a deep breath, then glanced at the bottle of Moutai that each of the three men was carrying when they got off the plane: "Go back and pour these bottles into ordinary liquor bottles and send them to my father."

"Okay. We'll definitely get it done for you!"

Soon, 212 drove into Factory 430 and stopped outside the test stand. At this moment, the distinctive whine of the turbo engine was slowly disappearing.

"Great! With the new large fan, the thrust has doubled, which is perfect for our H-6 bombers. Now, the higher-ups will no longer criticize our Spey for being one of the three foreign mars." Old Lin was overjoyed.

Spey has been brought in, but what will they be able to do with it? Nobody knows!
Fighter jets complained that its high-altitude thrust was too poor, and bombers complained that its military thrust was insufficient. The import project that cost a lot of money back then could not find a suitable aircraft. As a result, not to mention the engines they produced themselves, the dozens of Spey engines that were imported could only be left to gather dust in the warehouse!
Now, with the turbine and the larger fan replaced, the thrust of the Spey engine has been successfully increased to ten tons, making it seem like it was tailor-made for the H-6 bomber! Looking at the engine, which is now several times thicker, Old Wang sighed, "Yes, the Spey project is very important. Its engine will become the heart of our H-6 bomber... Hey, Qin Liang is here?"

"Yes, I'm here." Qin Liang looked at the large machine on the test bench: "Progress is quite fast!"

“That’s right, the speed of research and development in the East is unbelievable!” Schroeder said excitedly, “The advanced turbine blades produced by the East, combined with these brand-new fan blades, have greatly increased the thrust of the civilian Spey. This is definitely the best-modified Spey ever!”

Everything else remained the same, except for the enlarged low-pressure turbine at the rear. The turbine blades were also replaced with those produced by Dongfang itself, and the composite material fan blades were a first for Dongfang, and they passed all kinds of tests perfectly!

"With a maximum thrust of ten tons and a weight of just over two tons, the key is fuel consumption, which is only one-third of that of the WP-8 turbojet engine. If other data remain unchanged, the range can be increased by two or three times. Conservatively speaking, 10,000 kilometers is no problem!" Old Wu said with great emotion.

The original H-6 had a maximum range of only 5,800 kilometers, and that was with only three tons of bombs. If it carried nine tons, the range would be reduced to two or three thousand kilometers, making it a true medium-range bomber.

With a new engine and a range exceeding 10,000 kilometers, it becomes a strategic bomber!

Putting aside other uses for the Spey, as long as it can be supplied to the H-6 bomber, the Spey will continue to be produced in an endless stream!

“Mr. Qin, the performance of this composite material fan blade is indeed excellent,” Schroeder continued. “According to our previous agreement, you should hand over the technology to us. Of course, we will also help you complete the second phase of Spey’s localization task in accordance with the agreement.”

“Okay, no problem!” Qin Liang nodded. “But… will you take it back to improve Spey?”

Of course not! For the British, the Spey is outdated. Rolls-Royce's best-performing commercial aircraft engine is the RB211. They almost went bankrupt developing this three-spindle engine, but now the RB211 has become Rolls-Royce's trump card!
The later Trent engine was also an improvement on the RB211. Rolls-Royce relied on this expertise to become one of the three giants in commercial airliner engines. Unfortunately, they lost to American companies in composite material fan blade technology. Now, if they could obtain the relevant technology from here, they could take it back and improve their own aircraft engines!

Lighter weight, increased thrust, longer lifespan... by any measure, this is exactly the technology they need!

“Of course not, we plan to use it in our own RB211 engine,” Schroeder said. “Rolls-Royce’s aircraft engine technology is number one in the world…”

Qin Liang waved his hand, indicating that he wasn't listening to Schroeder's boasting.

“Mr. Schroeder, if we use a different engine, the fan blades will have to be redesigned. Our previous deal didn’t include designing new blades for you. So, if you continue to commission us, you’ll need to pay us an extra design fee. Of course, we’re good friends, so we can’t make money off you. Just give us a symbolic fee of ten million pounds.”

What?
Schroeder's eyes widened. Ten million pounds?

If this were in the UK, it wouldn't be much, but... for people from the East... is it worth it?

"No need. Just give us the technology for these blades, and we can scale it up ourselves."

Qin Liang shook his head: "This is not something that can be solved by simply amplifying it, but... since you insist, then I won't say anything more."

We value the Spey as a treasure, but the British treat it like a blade of grass. The British treasure the RB211, so Qin Liang decided to hand over the technology of this blade to them. We can't break our promise.

However... since they've asked for ten million pounds, they'll definitely get their hands on it!

"Okay, give it to us now!"

"Ahem, well, we still need to organize some data. Please don't worry, stay and help us complete the second phase of Spey's localization. We will definitely hand over all the technical data to you before this is finished."

We can't afford to repeat the mistakes we made with the WS-9 turbofan engine! Let the British leave all their technology behind!

"But……"

Before Schroeder could finish speaking, someone rushed in from outside, shouting loudly.

"The Spey engine has been upgraded to ten tons of thrust? Great, great, that's fantastic! Our Y-10 finally has a mature engine! Let me see, let me see, where is it..."

He was of medium height, dressed in a Zhongshan suit, with hopeful eyes and full of energy.

This is...Old Ma?
