Originally, these imported buses from Europe could even sell for more than 2 million, but with the launch of the fuel cell version of the Huaxing Group's buses, which cost between 1.2 million and 1.5 million, there is no market for these imported buses.

The domestic joint venture production of buses in terms of comfort, environmental protection and fuel consumption is not the opponent of fuel cell buses, because the foreign product design drawings of these joint ventures are stored in the production computer, some complex modules are completed through imports, and domestic companies simply do not get the skills and management experience they want.

Moreover, the joint venture generally produces high-end products, and the market capacity is already small, and there is no chance to fight back when the fuel cell bus launched by Zhongyuan Automobile Company seizes the high, medium and low-end market.

In the past two years, the losses of several joint ventures have become more and more serious, and foreign parties have begun to retreat, and several domestic bus manufacturers are also purchasing fuel cells and motors and chassis from Huaxing Group Company, and they have also begun to produce their own fuel cell buses.

Zhongyuan Automobile Company has no intention of fighting a price war at all, and these joint ventures themselves will not be able to hold on to it first-

These European bus manufacturers have no measures to produce low-cost fuel cells, and the degree of motors cannot catch up with Huaxing Group Company.

Xu Youlun also learned from other sources that the army's weapons and equipment have been fully equipped with fuel cell power packs, and began to upgrade and reform some old-fashioned equipment in service, and completely ended the purchase of power packs from abroad.

A few days ago, Yang Jie visited the Naval University of Engineering, and Xu Youlun also guessed that Huaxing Group Company was supplying fuel cells and motor skills for naval weapons and equipment.

This makes Xu Youlun have to sigh that the progress of Huaxing Group Company's rapid realization of industrialization after controlling the core technology patents is so fast, and in recent years, the fuel cell and motor technology have been rapidly expanded to all industries at a speed that is almost visible to the naked eye.

He is also very optimistic about Huaxing Group's intention to expand fuel cell and motor technology to the civil aviation industry, which also represents the direction of civil aviation aircraft in the future.

Xu Youlun naturally mentioned it, and told Yang Jie quite excitedly about Huaxing Group Company's reform of the electric propelled passenger plane for the Bombardier Group.

"It's really hard to say. ”

Although Yang Jie doesn't like to pour cold water on people, he still has to give Xu Youlun a preventive shot.

"Our Huaxing group company to Bombardier's group company to install fuel cells and motor propellers, is a major change, this aircraft needs to re-obtain the airworthiness certificate, especially to obtain the United States airworthiness certificate is a very troublesome thing, this is not only a superficial technical problem, many times related to national interests and political level. ”

Xu Youlun nodded: "You are right, if the Boeing Group Company is in the way of this, it is indeed very difficult to get the airworthiness certificate of the United States." ”

As a potential competitor to Boeing and Airbus, Bombardier Group, as the first company to use fuel cells and motor rotor systems as power, if its products are put into the market, it will have a great impact on the existing international aviation market.

"However, the Bombardier group still has connections, and they are actively helping us apply for fuel cell and motor rotors to obtain airworthiness certificates, and our company has also made various preparations for review. ”

In the memory of the previous life, the R project led by the Huaxia National Aviation Group Company was also developed during this time period, and it was only in the development stage that the domestic airworthiness certificate was obtained, and it was not until 07 years that the prototype was created, and then the project was taken over by the Commercial Aviation Group Company, but it was a delay in getting the airworthiness certificate of the United States, and after 15 years of formal entry into the domestic market operation, it has not been nodded by the Federal Aviation Governance Bureau.

Similarly, the 919 will also encounter such difficulties, without the blessing of the United States airworthiness certificate, the domestically produced aircraft will not even be able to fly in the Sea of Japan.

In the middle, Huaxia and the United States have always maintained the mutual certification of airworthiness certificates and maintained their own grasp and pursuit of standards, while the United States has always been hegemonic and unwilling to absorb this incomplete method of obtaining evidence according to American standards, so it has made many difficulties for domestic autonomous large aircraft in the validation process.

However, many domestic enterprises that produce large aircraft parts have been relatively smooth in obtaining the United States airworthiness certification.

The turbofan engine and the motor rotor system mounted on the helicopter are being certified by the United States for the airworthiness certificate at this time.

In the previous life, although the 919 could not get the US airworthiness certificate, it was still relatively popular in the domestic market and the non-mainstream international market, and won 570 aircraft orders from 23 users around the world, which is still a very good result.

It is also because the U.S. review is very cumbersome and strict, and even the U.S.'s own domestic Boeing will not easily produce a lot of models, but will continue to upgrade and revise the models that have obtained airworthiness certificates, so that it is easier to obtain airworthiness certification.

The new models are continuously developed on the basis of the 130 developed by the previous Fokker company, and are fixed at 130 to 150 seats, so that the risk is much smaller.

In the evening, Yang Jie also talked to Luo Binghuan about these things in Luo Binghuan's study.

"Before the official delivery of the 200 small regional jets that we reformed for the Bombardier Group, the fastest flying is the Bombardier 400, with a cruising speed of more than 600 kilometers per hour, using two Pratt & Whitney 150 turboshaft engines, each with a power of 3780, equipped with 6 propellers made by the company, although the speed flies faster, but it will also bring higher fuel costs. ”

Yang Jie said: "We have developed this set of fuel cell integrated propulsion system, including propellers, motors have been redesigned, propeller blades use more propellers, aerodynamic layout has also been optimized, can improve the cruising speed of 200 to 800 kilometers per hour, the noise of the propellers is also reduced by at least 20% of similar products, due to the application of motors, the biggest noise source is the noise of the propeller blades." ”

"It's close to a jetliner at such a fast speed. Luo Binghuan said in surprise.

"This is also due to the fact that Changhe Aviation Group Company has a very powerful expert Liu Yuan in the research and development of rotors, and has developed a dynamic variable pitch propeller technique, which can make propeller aircraft fly faster and more efficiently. ”

Yang Jie said with a smile.

Since this expert Liu Yuan entered Ruisheng Technology Company, he has also put forward some of his own wonderful ideas, and the company has also let him do research and development.

This dynamic variable pitch proposed by expert Liu Yuan is based on a flexible cam made of flexible steel and other exotic components that work with the propeller system, the cam vector thrust uses the flexible cam to hold the propeller to lead the flow of air, and the variable pitch and the growth of the wing to produce higher speeds more efficiently.

After Ruisheng Technology Company tinkered with this device, it also carried out a large number of tests and verifications, which confirmed that this device is still very reliable, and it does not need to improve the speed of the propeller to achieve a high speed.

Moreover, the experimental data of this device show that if applied to the helicopter's rotor system and swash plate coordination, the aerodynamic limitation called lift asymmetry can be more effectively counteracted, and the climb speed and progressive flight speed of the progressive helicopter and the stability of the helicopter have been greatly improved.

The company has also applied for national patents for this device, as well as several national patents.

It can be said that variable pitch and cyclic pitch systems are a very effective means of increasing the progress of helicopters and turboprop aircraft at subsonic speeds.

When Luo Binghuan heard this, he looked at Yang Jie and said, "Your company's support for the research and development of new skills is really great!"

Yang Jie said with a smile: "I also learned this from the original Bell Labs, what new ideas did these scientists in Bell Labs have, the laboratory is to implement these ideas into specific product skills as soon as possible, and quickly let these product skills out of the laboratory." ”

"In fact, there is no shortage of genius ideas in our country, what is lacking is how to turn these genius ideas into specific product skills of the scientific research environment, Huaxing group company is to create such a research and development environment, and now the company also has such conditions. ”

Yang Jie said with a complacent face.
