Chapter 791 Quebec Hydropower

The main engines of the first two China Aegis ships are two UGT-2 gas turbines imported from Ukraine, with a single unit power of 25000 horsepower, or about 3.6 kilowatts, and a thermal efficiency of 2.7%.

According to the original history, we have to wait another two years.

On the basis of the UGT-25000 gas turbine, our country has produced a relatively mature GT-25000, or QC-280 gas turbine, and the second batch of China Aegis ships have the main engine.

But in this life, Dongsheng Heavy Industry's "Pearl River" aeroderivative gas turbine has participated.

The foundation of the "Pearl River" aeroderivative gas turbine is General Electric's LM-2500, which is a two-rotor gas turbine. The power and thermal efficiency are slightly worse than the three-rotor UGT-25000, but the reliability and maintainability far exceed UGT-25000.

After further improvement, Zhujiang has now reached a power of more than 4 horsepower, equivalent to nearly 3 kilowatts, and a thermal efficiency of 39%—basically catching up with the level of the LM-90 in the late 2500s.

In the end, it won the competition with GT-25000.

The navy has used LM-2500 gas turbines before, and was very impressed, and ordered 12 "Pearl River" in one go.

According to Yang Dongsheng's understanding, in the Navy's second batch of construction plans, the first two ships will continue to use two gas turbines as the main engine and two diesel engines as the auxiliary engine in a combined diesel-fuel configuration.

The latter two ships will directly adopt the power configuration of four gas turbines, and the hull will also be enlarged to the level of the Arleigh Burke Type IIA destroyer.

It is not only the engine that Dongsheng Heavy Industry has brought about changes. The gantry-type CNC laser cutting machine that is cutting steel plates in the workshop is also printed with the words "Dongsheng Heavy Industry".

It is no longer the time for modern warships to rely on the hull to resist the opponent's attack 100 years ago.

The thickest steel plate used by the China Aegis is less than 3 centimeters, and the advantages of flame cutting and plasma cutting in cutting thick metal plates are gone.

This time, the steel plate cutting task was mainly handed over to this gantry CNC laser cutting machine.

Laser cutting has a series of advantages such as high precision, fast speed, small thermal deformation, and the cutting surface can be directly used for welding without grinding.

It not only reduces labor and material waste, but also speeds up production and improves product quality.

This is also the confidence that Jiangnan Shipyard dared to start construction of two more Chinese Aegis ships after the few relocation time limits before the 2010 World Expo had been determined.

Standing in front of the huge dock, opposite the Huangpu River is the World Expo Center under construction. A huge gantry crane blocks the crowd and the Huangpu River.

This gantry crane is printed with the logo of a well-known domestic port machinery manufacturer - Zhenxia Heavy Industry.

Looking at the logo of Zhenxia Heavy Industry, Yang Dongsheng couldn't help but think of a report made by Dongsheng Heavy Industry not long ago.

"How is our cooperation with Zhenxia Heavy Industries?" Yang Dongsheng asked Vice President Wang.

"The progress is much slower than expected, mainly because the certification procedure is too cumbersome!" Vice President Wang said.

Zhenxia Heavy Industry is also a well-known enterprise in China. Its port machinery ranks first in the world for many years. In their previous lives, they built the world's largest single-arm slewing crane ship, the largest self-propelled cutter suction ship in China, and gantry cranes and semi-submersibles. Boat……

Many people bought the company's stock after watching a certain station's program, and then got stuck.

Many people don't understand why Zhenxia Heavy Industry's output value seems to be so large, why the profit is so low, and it will lose money if it is not careful.

In fact, the problem of Zhenxia Heavy Industry is also a problem of many domestic industrial enterprises.

Although many of their products are good and can be called high quality and low price, the key equipment such as bearings, motors, diesel engines, valves, and pumps are heavily dependent on imports.

Although it bears the name of heavy industry, it is often a steel structure manufacturer.

The cooperation between Dongsheng Heavy Industry and Zhenxia Heavy Industry is definitely a win-win situation, but these things will not be completed in a short time. Zhenxia Heavy Industry's products are mainly marine engineering equipment, which requires a lot of messy classification society certification.

This is a very time-consuming and energy-consuming job.

Back at the company headquarters, after a short meeting, Office Director Li knocked on the door and said, "Tremblay from Hydro-Québec is here."

Earlier, Yang Dongsheng asked Director Li to bargain with Hydro-Québec, promising that he would personally come forward at critical moments.

Yang Dongsheng nodded, stood up and buttoned his suit, turned his head and glanced at Yang Miao, who also stood up.

The father and son came to the small conference room supporting the office, and soon several foreigners walked in.

The leader was a white man in his forties. This white man was tall, dressed in a well-tailored high-end suit, his beard was well groomed, and his hair was so shiny that even a fly could slip on it.

The white bearded man spoke in a very awkward-sounding Mandarin, "Hello, Mr. Yang, nice to meet you!"

"Hello, Mr. Tremblay!" Yang Dongsheng greeted, then turned to look at Yang Miao, "This is my son!"

Seeing this, Yang Miao took a step forward and said in French, "Hi, nice to meet you!"

Tremblay shook hands with Yang Miao, and said in French, "I'm glad to meet you too, you're such a smart guy!"

After speaking, he patted Yang Miao on the shoulder.

Canada is a country mainly of British descent, and the official language is mainly English, but Quebec is an exception.

Quebec was a French colony in history, most of the residents are French, and the official language is French.

Tremblay is a typical French surname and the most common surname in Quebec.

France still has a huge influence in Quebec. Take this Tremblay as an example. He is not only French, but also graduated from the Paris Polytechnic University.

The two sides sit down respectively, and the translator comes in and sits down.

Yang Dongsheng doesn't know French, and Tremblay also knows a word of Chinese, which he learned last night.

In the past two years, foreigners have gradually figured out a routine. When meeting Chinese people, speaking a sentence of Chinese, no matter how strange the tone, can easily win the favor of the Chinese side, and finally reap unexpected benefits.

Tremblay used the same trick today.

It's a pity that he didn't know that a group of foreigners under Yang Dongsheng didn't think that a white man could speak a few words of Chinese just to have a good impression of him.

Yang Miao was even more unhappy. Although his cleanliness got better, he was still not used to shaking hands with strangers, especially when the other party patted him on the shoulder. His clothes couldn't be washed in the bathroom.

Today, he might have to tilt his neck—fortunately, he didn't touch his head.

"Mr. Tremblay, please forgive me. After paying an entry fee of 5000 million US dollars, there will be a patent royalty of 5000 US dollars for a ton of lithium iron phosphate battery. We cannot accept this price!" Yang Dongsheng said directly when he came up manner.

After listening to the translator quietly, Tremblay said, "Regarding this matter, I specifically asked the headquarters last night. In order to show our sincerity, the headquarters has agreed to reduce the entry fee to 4800 million U.S. dollars and the patent royalty to $4800 a ton.”
