$50 million for one engine!

This is an unprecedentedly high price, which is basically more than twice the price of the Ruida 900 engine, which costs $100 million if an aircraft uses two turbofan 30 engines.

Many people are well aware of the price of the Airbus A380 passenger aircraft, an Airbus A380 is about more than 300 million US dollars, and the price of the engine accounts for one-third of the cost of the aircraft, which does not seem to be expensive.

But the price of an engine of 50 million US dollars, everyone can not accept it for a while, this is an unprecedented high price, and no engine has ever been able to sell at this price.

"Mr. Li, the selling price of $50 million, this is too expensive!"

"Yes, it's sky-high!"

“……”

More than one person asked loudly, and Li Tianfeng noticed that these people are basically foreigners, and they basically speak English or French.

Li Tianfeng smiled slightly: "I think the price of 50 million US dollars is not expensive, I will calculate an account for you, first of all, one of our turbofan 30 engines can top two of others, and an Airbus A380 only needs two turbofan 30 engines, which is one of them." ”

"Second, our engine performance is excellent, fuel consumption per unit thrust, emissions, etc. are much ahead of the turbofan 30 engine competitors, that is, the same flight from Beijing to Paris or London, with our turbofan 30 engine, at least more than 15% fuel savings."

"Thirdly, our turbofan 30 engine is very maintainable, with maintenance costs and usage costs more than 20% lower than its competitors."

"Fourth ......"

Li Tianfeng one, two, three, four o'clock, little by little and everyone calculated an economic account, everyone is a person in the aviation industry, listening to Li Tianfeng's calculation, everyone gradually calculated in their hearts.

This economic account is easy to calculate. It was quickly understood that after such a calculation in mind, everyone found that even if it was a price of 50 million US dollars, it would be more economical to use a turbofan 30 engine. More cost-effective.

As soon as this account is calculated, many people look at Li Tianfeng with envy, and everyone understands in their hearts that the turbofan 30 engine will definitely have a very strong competitiveness.

With such economy and advanced performance, many people can even imagine that once the turbofan 30 engine is put into the market, it will definitely occupy a large share of the large trunk airliner market.

Mainline airliners ranging from 300 to 500 seats can use turbofan 30 engines. Ultra-large mainline airliners with more than 500 seats, such as the Airbus A380 passenger aircraft, can also use two turbofan 30 engines.

The economic accounts understand that everyone is most concerned about when the turbofan 30 engine will be put into the market, so some people asked loudly: "Mr. Li, when will the turbofan 30 engine enter commercial operation?" ”

Li Tianfeng said: "This year we will complete the comprehensive design of the turbofan 30 engine, and next year we will complete a series of test runs and flight tests. Within two years, our turbofan 30 engines would be in series production. ”

Within two years!

Many people were amazed. What a concept it is that such a super engine can enter mass production within two years.

However, thinking about any engine developed by Tianfeng Technology Company before, it basically only took one or two years, and everyone was relieved.

Global launch of the turbofan 30 engine. It was a great success, from 9 a.m. to 12 p.m., and as soon as the press conference ended, there was a lot of press coverage, and the turbofan 30 engine became famous like never before.

End of the press conference. Tianfeng Technology Company held a grand celebration banquet at the Beijing Hotel.

In the afternoon, Tianfeng Technology Co., Ltd., Boeing Company, and Airbus signed order contracts respectively, Airbus Company ordered 200 turbofan 30 engines from Tianfeng Technology Co., Ltd. for the first batch, and Boeing Company ordered 150 turbofan 30 engines from Tianfeng Technology Co., Ltd.

200 turbofan 30 engines! Worth $10 billion!

150 turbofan 30 engines! Worth $7.5 billion!

That's a total of $17.5 billion!

This is the result of this global press conference, and it is also the harvest of Li Tianfeng's foreign trip more than a month ago.

On his last trip abroad, Li Tianfeng visited Airbus and Boeing, and promoted his own turbofan 30 engine very well, and also calculated an economic account for the executives of these two companies.

Li Tianfeng's economic calculations are very clear, and everyone no longer feels that the price of 5,000 US dollars is expensive.

The contract was signed, and on the official website of Tianfeng Technology Co., Ltd., it was officially announced that it had signed an order for 200 turbofan 30 engines with Airbus and an order for 150 turbofan 30 engines with Boeing.

As soon as the news was released, the turbofan 30 engine was even hotter, especially in China, which can be described as hot.

350 turbofan 30 engines!

A total value of $17.5 billion!

The turbofan 30 engine, like a dazzling star, is simply born. In China, also because of the turbofan 30 engine, a strong sense of pride in the hearts of the general public has swept across the country.

The press conference was very successful, Li Tianfeng took everyone back to Tianfeng Technology Company, at the gate of the company's large factory, Li Tianfeng, who got off the car, found that several senior executives at home, with a group of middle-level and grass-roots managers, as well as a large number of employees, welcomed them.

Everyone already knows about the order for 350 turbofan 30 engines, and also knows the massive reports of the news media.

Yang Xianfeng also rushed over from Tianxin City, at this moment, Yang Xianfeng's heart was full of joy, and he even thought in his heart how wise his choice was at the beginning.

After Li Tianfeng returned to the company, he was full of enthusiasm and passion for the development of the turbofan 30 engine, the development of the J-18 fighter and the J-30 fighter, and the three went hand in hand!

Seongnam base.

Wind tunnel laboratory, where wind tunnel experiments are being carried out on the J-30 fighter.

Wind tunnel experiment refers to an aerodynamic experimental method in which a model of an aircraft or other object is placed in a wind tunnel to study the flow of gases and its interaction with the model to understand the aerodynamic characteristics of the actual aircraft or other objects.

A J-30 fighter model is already here, this is a J-30 fighter model specially used for wind tunnel testing, although it is not a real J-30 fighter, but the shape is the same as the J-30 fighter, but the size is much smaller.

If a real J-30 fighter is used for wind tunnel testing, the air flow blows at a speed equivalent to flight, and its power consumption will be amazing.

According to the principle of similarity, the aircraft can be made into a geometrically similar small-scale model, as long as some similar parameters are maintained, the air velocity of the test can be lower than the flight speed within a certain range, and the aerodynamic force acting on the aircraft during the real flight can be deduced according to the test results

Judging from the test situation, what is now being carried out is the pressure measurement test of the J-30 fighter.

The force measurement test is a wind tunnel experiment that uses a wind tunnel balance (see Wind Tunnel Test Instruments) to measure the aerodynamic forces and moments acting on the model. It is one of the most important experimental projects in wind tunnel experiments.

"Expert Wang, this is the test data, you can take a look."

As one of the aerodynamic design experts of Tianfeng Technology Company, Wang Dayong was responsible for a series of wind tunnel tests of the J-30 fighter.

The force measurement experiments mainly include: longitudinal and transverse force measurement experiments of the whole model and components, jet flow experiments, hydrostatic and aeroelastic experiments, force measurement of external objects and delivery trajectory experiments, etc.

Just now it was the longitudinal and transverse force measurement experiments in the force measurement experiment, Wang Dayong took these test data and looked at them, nodded, and then said loudly: "Start the jet flow test!" ”

According to the experimental outline, several technicians began the jet flow test again.......

Domestic, a well-known shipyard.

Speaking of this shipyard, it can be described as famous, our 052D missile destroyer was built here, in addition to 052D, there are also 052C missile destroyers, as well as many other types of ships.

The shipyard of the plant is busy, and one of the 052C guided missile destroyers under construction is in the stage of power system construction and installation, and two large gas turbine engines are waiting to be installed in the power compartment of the missile destroyer.

Several workers were busy, everyone was preparing to install the engine, one of the workers seemed to be relatively young, saw the two gas turbine engines, couldn't help but softly "huh", and then shouted loudly.

"Brother Yang, come and take a look, it seems that the engine is wrong!"

The "Brother Yang" in the mouth of the young workers looks to be in his thirties, and it seems that he should have more than ten years of working experience, which is considered an experienced old worker.

"Brother Yang" immediately walked over, looked at the two engines, and couldn't help but say: "Yes, it doesn't seem right, the engines used to be full of foreign yards, imported from Ukraine, which looks completely like domestic engines." ”

"Brother Yang", who looked puzzled, immediately looked carefully, the engine was relatively large, with a diameter of more than one meter, and the weight reached seven or eight hundred kilograms.

Several other workers next to him, everyone also came up one after another, around the two engines to look up, suddenly, a worker with surprise in his tone, loudly: "Look, everyone! ”

Everyone followed the worker's point, everyone saw the icon and words of "Tianfeng Technology Company", everyone glanced at each other, and thought in their hearts, is this the engine produced by Tianfeng Technology Company.
