"This is a gas turbine engine manufactured by Tianfeng Technology!"

Immediately, a worker shouted loudly, and "Brother Yang" also nodded and said: "That's right, this is a domestic gas turbine, which is manufactured by Tianfeng Technology Company." ”

"Tianfeng Technology Company I know that the turbofan 30 engine they produce is very popular, and it is said to be one of the best, the best comprehensive performance and the largest thrust turbofan engine in the world."

"Without thinking, Tianfeng Technology Company not only produces aero engines, but also produces gas turbine engines for ships."

"yes, I really didn't think about it."

After recognizing that this is the gas turbine engine produced and manufactured by Tianfeng Technology Company, everyone looked around these two engines, and even guessed in their hearts that since it is a gas turbine engine produced by Tianfeng Technology Company, the quality and performance must be excellent.

Everyone was arguing, and two people who looked like technicians walked over together, one of whom was still wearing the work clothes of Tianfeng Technology Company.

The RQ7500 gas turbine engine officially entered mass production, was officially delivered to the military, and was transported to the shipyard to be loaded with 052C and 052D missile destroyers.

Chen Honggui is one of the technicians in this service team, and together with Chen Honggui, he is a chief technician at the shipyard.

Seeing the two of them coming, "Brother Yang" immediately said loudly: "Cao Gong, you came just in time, what's going on, should the engine of this 052C warship be replaced with this gas turbine engine produced by Tianfeng Technology Company?" ”

Cao Gong said: "This is the reason why I came here this time, this 052C power is two RQ7500 gas turbine engines, this is the process technical information, wait a minute, I will guide you to install." ”

This time. Everyone understands, but the problem also comes, previously, both 052C and 052D were powered by firewood, that is, two gas turbines and two diesel engines were installed.

Do so. Naturally, in order to save fuel, two diesel engines are used at low speeds, and two gas turbine engines are used at medium and high speeds.

Gas turbine engines, powerful, but very fuel-guzzling, are simply an "oil tiger", because of this. A warship uses four engines, fuel-powered and two engines each.

"Cao Gong, what about the diesel engine, do you only install these two gas turbine engines?" Immediately, there was a loud question.

Cao Gong said: "Yes, from now on, all the 052C missile destroyers we produce and manufacture will be replaced by two gas turbine engines produced by Tianfeng Technology Company. Diesel engines are no longer installed. ”

"No wonder, I'll just say it. Why has the design of this power compartment changed so much compared to before, and I have been wondering why the original power has been so much improved. ”

There are also humanitarians: "No, Cao Gong, if we only use two gas turbine engines, how can we stand this fuel consumption?" ”

Cao Gong smiled slightly. Then he looked at Chen Honggui, who had not spoken beside him, "Chen Gong, now I need you to explain it to everyone." ”

Chen Honggui nodded and said loudly: "Hello everyone, this is a new type of gas turbine engine produced by our company. Model RQ7500, rated output of 7500 horsepower, unit horsepower fuel consumption is more than 25% lower than the previous diesel engine, and the output power is adjustable, with a very advanced digital fuel regulation system. ”

That is to say, under normal conditions, the rated output power is 7500 horsepower, but it can also be adjusted up and down, and the output power can range from more than 1,000 horsepower, two or three thousand horsepower to seven or eight thousand horsepower, and even the maximum output power can reach nearly 10,000 horsepower.

The output power is different, the fuel consumption is also different, such as when the output power is only one or two thousand horsepower, the combustion chamber is completely poor oil, the fuel consumption is very small, very fuel-efficient.

Chen Honggui said: "The RQ7500 engine not only adopts an advanced digital fuel conditioning system, but also adopts a lot of very advanced designs, such as the design of the combustion chamber, which is at least a generation ahead of other mainstream marine gas turbine engines. ”

"Our 052C missile destroyer, equipped with our RQ7500 gas turbine engine, is more fuel-efficient, and correspondingly, the maximum range is increased by more than 30%."

The increased range means that the 052C can travel farther after a resupply, and everyone understands this.

So advanced!

These workers looked at each other, their hearts were full of shock, although they had long guessed in their hearts that the gas turbine engine produced by Tianfeng Technology Company must be advanced, but they were far from thinking that it would be so advanced.

RQ7500 gas turbine engine, not only fuel-efficient, reliability is also very high, maintenance costs, use costs are very low, long service life, so the military top decided to start from this 052C, the future 052C missile destroyer all replaced with Tianfeng Technology Company's RQ7500 engine.

In addition, 052D will also be replaced with RQ7500 gas turbine engine, before the new engine, 052D is also firewood power, two domestic version of the gas turbine engine, two domestic diesel engines, from now on, all use two RQ7500 as power.

RQ7500 gas turbine is widely used in 052C and 052D missile destroyers, and the military is very optimistic about this gas turbine.

In addition, the military is also preparing to once again give Tianfeng Science and Technology Company a research and development task, requiring Tianfeng Science and Technology Company to develop a gas turbine with higher power in order to meet the needs of 10,000-ton ships.

RQ800 and RQ2000 gas turbine engines are widely exported, and it is estimated that it will not be long before someone will definitely find them and want to buy RQ7500 gas turbine engines.

Tianfeng Technology Company.

After more than two months of test runs, the turbofan 25B engine has basically completed all the test projects, including a series of test runs on the high-altitude platform.

In the test engineering center, the turbofan 25B engine began to enter the 500-hour long-term test test, and only this long test was not completed in the test project.

As the chief designer of the turbofan 25B engine, Sun Xiaoping has been paying attention to the test run of the turbofan 25B engine, and now, in his office, carefully reading a series of test reports.

These test reports are a thick stack, but Sun Xiaoping is very patient and is carefully flipping through them.

In the office.

Li Tianfeng is the same, is seriously looking at a large number of design materials, these design materials, all of them are J-18 fighters, so far, this fighter has completed the design, Li Tianfeng is in the final review.

There are too many design materials, Li Tianfeng can only look at the key points, and the rest of the design materials are checked and reviewed by Sun Xiaoping, Qiu Wenan, and a group of design experts from Tianfeng Technology Company.

Even if it is only key information, Li Tianfeng has been reading it for several days, and after reading these materials, Li Tianfeng is very satisfied with the design of the J-18 fighter!

After reading the last design drawing, Li Tianfeng was about to take a sip of tea, and the phone on the desk rang, the phone was called by Lei Yong, Lei Yong said on the phone, the J-30 fighter will immediately enter the static test of the whole aircraft.

Two months ago, the static test was mainly a structural static test, and this time it was a static test of the whole machine, the so-called whole machine, as the name suggests, is a whole aircraft, but there are no electrical wiring, instrumentation, radar and other things, and the rest of the things should be all available.

The ability to assemble a complete aircraft indicates that the trial production and verification of parts of the J-30 fighter has entered the final stage, and soon, it may be the assembly of the first prototype.

After receiving Lei Yong's call, Li Tianfeng was happy for a while, if the static test of the whole machine was successfully completed, it would be a milestone achievement.

………

No. 2 final assembly plant.

Zhou Ding, Lei Yong, and Li Dawu are all here, several engineering and technical personnel, several skilled workers, and everyone is preparing for the static test.

This J-30 fighter looks exactly like what you saw on the previous pictures, at least the appearance looks no different from the official J-30 fighter.

On the test bench, the J-30 fighter was quietly there, a group of workers and technicians were busy, among them, Lei Yong also pointed out and shouted from time to time, pay attention here, pay attention to there, and so on.

Zhou Zhou Ding looked at the J-30 fighter, and then at Lei Yong, who was busy, and said to Li Dawu next to him: "Dawu, our J-30 fighter finally has such results, not to mention, I am really a little excited in my heart." ”

Li Dawu said: "According to our development plan, the first prototype will enter assembly starting next month, which is really good. ”

Zhou Ding was about to speak, when he saw the figure of Li Tianfeng in the distance, he immediately swallowed back what he was about to say, and then said, "Dawu, Mr. Li is here." ”

called Lei Yong, and the three of them greeted him together.

Li Tianfeng naturally wanted to come over to take a look at the static test of the whole machine, and when he saw the three of them coming up, Li Tianfeng smiled and nodded, and everyone walked in front of the J-30 fighter together.

This J-30 fighter is on the test bench, Li Tianfeng looked at it, and turned back to Zhou Cheng and others with satisfaction: "Our J-30 fighter, the static test of the whole machine is very important, and we will strive for one-time success." ”

Lei Yong, as the technical leader of the J-30 fighter, naturally knows the importance of the static test of the whole aircraft, Lei Yong nodded vigorously and said: "Boss, we will definitely strive to pass this test at one time." ”
