Jiang Yingzheng very much agrees with Yang Jie's idea of excavating the maximum value of the passenger plane, although the passenger plane can theoretically fly forever, but in real life, the performance of the aircraft after wind and rain will definitely be reduced.

However, aircraft manufacturers still have their own methods, by replacing and upgrading some fragile parts, such as engines and landing gear, tires, skins, etc., this method can extend the service life of the aircraft, such a situation is actually very common in some backward foreign countries.

However, he was more interested in the electric propeller passenger plane that China Fokker was about to launch, and he also asked about it.

"The electric propeller passenger aircraft developed by our company has been tested and verified for more than seven years, and now it has finally obtained the domestic airworthiness certificate. ”

Yang Jie said with a smile.

Jiang Yingzheng also sighed: "After so many years of tossing, it's finally time to blossom and bear fruit......

Bombardier Group took the initiative many years ago to come to the door and Huaxing Technology Group Co., Ltd. to cooperate in the development of fuel cell power packages with lower fuel consumption and lower noise, originally thought that it was quickly obtained the FAA airworthiness certificate, but these years it has been difficult, and the development process has indeed encountered a lot of technical problems, and the prototype crashed in the plateau area in the middle, and the losses were heavy, which also made the domestic Civil Aviation Administration dare not give airworthiness certification, and the progress has been delayed.

However, Yang Jie will naturally not give up, and has always continued to promote the development of electric propeller airliners and continue to carry out various technical breakthroughs.

Over the years, the fixed-wing electric rotor system developed by Ruisheng Aviation Technology Co., Ltd. has now developed to the third generation, and the prototype equipped with this power system has also completed the test flight content in various complex environments, and has also established a very complete set of technical standards for electric propeller airliners.

The technical standards department of the Civil Aviation Administration of China issued an airworthiness certification to the electric propulsion system developed by Ruisheng Aviation Technology at the beginning of this year.

In fact, it is more difficult to transplant the electric rotor system developed by Ruisheng Aviation Technology for use in helicopters to passenger aircraft, because the rotor of the helicopter is very large, and more needs large torque, while the passenger aircraft requires higher power motors, which are more technically difficult, and also use more new technologies, which is inevitable.

Over the years, Huaxing Technology Group has made various advances in the technology of materials, processing technology, electromagnetic technology, etc., and Ruisheng Aviation Technology Company has finally overcome the problems of poor adaptability, weak load capacity and reliability.

In particular, AAC Technologies has used lighter alloy materials on the motor, as well as new permanent magnet materials and new motor structures, of course, a large number of electromagnetic simulations have been carried out by computers, and the power-to-weight ratio of new motor products has reached 6.2 kilowatts per kilogram, which is very amazing.

Although the cost of these new materials is still very expensive, and the electric propulsion system is very expensive, as long as it can be built, the cost can easily go down with the growth of production capacity.

In order to develop such a power system, Ruisheng Aviation Technology has invested more than 6 billion R&D funds over the years.

However, Yang Jie did not feel the slightest distress about this, now that this power system is mature, the money invested before can easily be earned back several times and ten times.

He Yongqing said: "Yang Shao, your power system is more cost-effective than the traditional propeller, and other companies are really powerless when this electric propeller airliner is launched." ”

At present, the price of hydrogen fuel in China is lower than the price of aviation kerosene, and the energy density is higher.

No matter what kind of airline, where the airline, the biggest cost is the fuel cost, which basically accounts for about 30% to 40% of the operating cost of the entire airline, and fuel saving is very important to the airline, and it is also forcing the engine manufacturer to continue to develop more fuel-efficient engines, because some other costs are difficult to have a significant reduction.

Now Ruisheng Aerospace Technology's electric propulsion system is almost half of the fuel compared with the traditional turboprop engine, which is equivalent to giving the airline a lot of extra money out of thin air, and it also reduces the noise to a very low level, and the comfort is also greatly improved, which is very powerful.

He Yongqing also knew that Huaxing Technology Group also established a new company, Centec Aviation Technology Company, to operate the turboprop passenger aircraft business of the acquired Bombardier Group, and also included the turboprop passenger aircraft business of Fokker Group into this newly established company.

With the airworthiness certificates of several turboprop airliners on hand, the new company could easily propose an electric propulsion propeller airliner.

And with the rapid rise of the domestic aviation industry, now the domestic Civil Aviation Administration has signed a contract with Europe and the United States for mutual certification of airworthiness certificates, that is to say, as long as the domestic airworthiness certificate is recognized, the aircraft designed and produced in China can be sold to the world, and there will be no obstacles.

Perhaps in the past, Europe and the United States would implement technical barrier policies for domestic aircraft, but now the rapid development of the civil aviation industry has deprived these Western countries of their bargaining weight.

Because the huge market with a population of 1.4 billion is so large that even if domestic aircraft manufacturers are digesting orders in the domestic sector, it is a huge number.

And Boeing and Airbus without the domestic market, the losses will be astronomical, which is a situation that none of them wants to see.

If Eagle Sauce dares to implement the ban in this regard, then China will definitely formulate special provisions to implement technical barriers to Eagle Sauce's Boeing products, with the current volume and strength of the civil aviation field of the two countries, the two sides will set up barriers to each other, and Boeing will suffer unbearable losses.

"By the way, a Q400 passenger plane owned by Centec Aviation Technology Co., Ltd., which you founded, had an air crash in Eagle Sauce a few months ago, so it won't have a big impact on your new company, right?"

Jiang Yingzheng asked at this time.

"We also sent an investigation team, and it has been determined that the air crash accident was mainly caused by improper piloting, when the captain's reaction to the jittering lever was an inappropriate lever action, which caused the wing of the plane to stall, and the crashed plane crashed into the fuel pipeline on the ground, causing fuel leakage, which aggravated the intensity of the fire afterwards. ”

Yang Jie said: "Although the responsible party is not us, I have asked the technical department to conduct a complete computer simulation of this incident, and then the flight control system will be optimized to avoid the pilot's mistake." ”
