In fact, before the research and development of Wuzhi-10, Changhe Aviation Group Co., Ltd. carried the fuel cell and motor rotor system on the platform of the Zhi-9B transport helicopter, and several modified helicopters have already carried out various test flights, and carried out a series of test flight tasks in the plateau environment.

These modified versions of the Zhijiu are also the first to enter the plateau at an altitude of 3000 meters, and from the perspective of a series of test flight performances, the performance of the Zhijiu can be said to be very perfect.

Just like the Black Hawk helicopter manufactured and produced by Sikorsky, the power of the engine has also dropped sharply in the altitude environment, especially at an altitude of 6,000 kilometers, and the load does not exceed one ton.

The Qinghai-Tibet Plateau is a nightmare for any helicopter, and helicopters that appear to perform well on the plateau in other places are not enough to reach the Qinghai-Tibet Plateau.

When the Americans designed the Black Hawk, they also summed up the cruel experience of the Vietnam War, and required the helicopter to perform tasks in the forward zone with a high degree of maneuverability, especially the ability to climb, so that it could use vigorous maneuvering to evade ground anti-aircraft fire, so it could meet the requirements of the domestic military at that time.

None of the helicopters produced in China can perform tasks in the plateau area, and Huaxia has the largest plateau area in the world, and when the Black Hawk helicopter was purchased before, the military only needed to carry out some important personnel transportation tasks and search and rescue missions on the plateau, with a load of 600 kilograms.

However, it is not enough to lift artillery on the plateau, parachute to replenish troops and supply border posts, if you want to achieve this goal, you need to be able to provide turboshaft engines of more than 2,000 kilowatts in China, according to the level of domestic aero engines, now even a 1,000-watt power turboshaft engine can not be done, and there is also the problem of unreliable quality.

However, with the Huaxing Group Company has made a major breakthrough in the fuel cell and motor rotor system, especially the modified Zhijiu B, the altitude of the lifted off easily exceeds 6,000 meters, and the power is almost not reduced, and the load capacity has reached an astonishing six tons, which has fully met the requirements of lifting heavy weapons and equipment and transporting personnel and materials in the plateau area.

The military is very satisfied with this, and after more than a year of test flights, the military is also preparing to purchase more than 40 fuel cell version of more than 90 types of helicopters from Changhe Aviation Group Company, of which more than 30 will replace the Black Hawk helicopters that have been in service in the plateau area for more than 20 years.

Because the Zhijiu series has been in service for more than ten years, the fuel cell version of the Zhijiu has not been overhauled in appearance, nor has it used a large number of new electronic equipment like the Wuzhi-10, so the test flight time has been greatly shortened.

In the final assembly workshop, almost eight transport helicopters are being assembled.

Yang Jie walked to the side of the transport helicopter, looked at it, and said to Yu Feng, who was accompanying him: "Mr. Yu, now Changhe Aviation Group Company is in short supply!"

"Yang Shao, this is mainly because your company is too powerful in fuel cell technology and motor technology, and now it is also necessary to comprehensively replace the existing helicopter with a fuel cell version of the helicopter, and we are also stepping up the design and development of heavy-duty helicopters with more than 20 tons, and I hope that your company will provide more advanced fuel cell stack and motor product technology. ”

Yu Feng said.

"Our second-generation fuel cell technology has matured, and now we are developing the third-generation fuel cell technology, I hope that the energy conversion efficiency of our company's fuel cell stack can reach 85%, the weight and volume can be reduced, and the torque of the motor can be improved, but this will take three or four years, and it is estimated that it will take 05 or 06 years to come out with more mature products. ”

"The second-generation products that your company now provides are now the most advanced in the world, and Yang Shao is still not satisfied with this. Yu Feng said with emotion.

"Japan and the U.S. are now chasing after each other very hard, and if we stop, we will soon catch up, so we can't afford to slack off in the slightest. ”

Yang Jie said.

Since the beginning of the previous year, Toyota, Fuji Heavy Industries and other Japanese companies have joined hands to start research and development of fuel cell technology, the technical route is very similar to Huaxing Group Company, now Toyota has given up the technology of high-pressure hydrogen storage, and began to fully turn to the technical means of compound hydrogen storage, this year there are technical patents for compound hydrogen storage, and there are also technical patents for iridium cobalt alloy electrode catalysts.

Similarly, Weide has now started the research and development of compound hydrogen storage technology, and has also obtained some technical patents, while BMW Group, Mercedes, Audi, Volkswagen and other automobile manufacturers are making efforts in fuel cell technology, but the technical route is surprisingly consistent, that is, to keep up with the fuel cell technology of Huaxing Group!

In the face of so many competitors chasing after him tightly behind his ass, how could Yang Jie stop.

At this stage, Huaxing Group is the only company that has achieved large-scale industrialization in fuel cell technology, which is undoubtedly a signal to the world: fuel cell technology can be commercially produced!

Although they can't get the formula of catalyst and hydrogen oil, they can get what ingredients are in it through analysis, and then start to mix it themselves.

The Secretariat has also analyzed and estimated that in another two years, these car manufacturers will have new fuel cell products, and as for the specific performance, we will know at that time.

However, Yang Jie is not too worried about this, instead of worrying about these, it is better to devote more energy to the research and development of fuel cells, and develop hydrogen oil technology with higher efficiency fuel cells and higher hydrogen storage capacity.

This year, the industrialization of fuel cells alone has brought more than 2 billion US dollars in revenue to Huaxing Group, and the main revenue is still in the fuel cell buses and home fuel cell power systems launched in the United States and the backup medium-sized fuel cell power stations customized by enterprise companies.

It is also to achieve a relatively large scale of production, the production cost of fuel cells in the second half of this year has seen the extent of 60 US dollars per kilowatt, which makes Yang Jie very satisfied, Zhongyuan Automobile Company is also preparing to launch two fuel cell cars of 100,000 yuan and 200,000 yuan next year.

Yang Jie believes that next year's Huaxing Group will have a significant acceleration in fuel cell revenue.

In the past two years, he has recovered the money he had previously spent on fuel cells and motors, and has made a profit, and now there is no need for the head office to invest so much money in the electrochemistry laboratory, and now the laboratory has received 20% of these revenues as research and development funds have reached more than 3 billion, which is enough to support the follow-up research and development of the electrochemistry laboratory.

Yu Feng saw Yang Jieran looking at the Zhijiu transport plane that was being assembled with interest, and said with a smile: "Yang Shao, the final assembly of a transport helicopter is basically almost completed, and Vice President Yu invited: "Mr. Li, take a look on the board?"

Yang Jie nodded, and then boarded the helicopter.

He first looked at the transport compartment, then entered the cockpit, and sat in the driver's seat with great interest.

This transport helicopter, the pilot and co-pilot positions are positioned side by side in parallel, unlike the front and rear layout like Wuzhi Shi, the cockpit of the transport helicopter is well designed, relatively spacious, and the operability is also better, of course, it also uses the reinforced display screen provided by Tianma Technology Company.

After being reinforced, the display screen can be used in high temperature, low temperature, humid heat, salt spray and other environments, with a temperature range of minus 40 degrees and a maximum temperature of 85 degrees, and at the same time has high reliable anti-vibration ability and electromagnetic compatibility protection performance.

This is a joint production of Tianma Technology Company and Huaxia Electric Technology, and Wuzhishi also used this product, and the price is three times more expensive than ordinary products.

Yang Jie carefully inspected the internal equipment of this helicopter, and then came out satisfied.

"Yang Shao, I heard that Bombardier Aero Industries of Brazil is talking about cooperation with your company?" asked Yu Feng.

Yang Jie smiled: "Yu Dong, what news have you heard?"
