In Vietnam, Yang Jie visited the propeller production workshop of Changhe Aviation Group Company, and also saw that the company was producing composite main propellers.

The previous metal structure can no longer meet the new performance requirements, and it is necessary to develop more advanced composite material main propellers, and the company has encountered great difficulties in many key skills such as weight control, process production, and experimental verification.

The company's research staff conducted a comparative analysis of the aerodynamic parameters of various airfoils, and comprehensively considered the different requirements of the hovering state and the forward flight state for the propeller parameters, and finally determined the aerodynamic shape of the propeller.

These skilled staff racked their brains to reduce the weight of the propellers, and after understanding the hardships behind the development of the main propellers, Yang Jie also had to admire these staff who silently contributed to the country's weapons and equipment.

Yang Jie for Huaxing Group Company's fuel cell and motor products can enter the field of military helicopters is naturally very important, the company has no experience in research, production and production of helicopters, and now can cooperate with Changhe Aviation Group Company to set up a research and development center to enter this field, but also to open up a market segment.

At present, the purchase price of the turboshaft engine and transmission system transmission imported from abroad by Huaxia is close to 2 million US dollars, and the price of 3,500 kilowatts of fuel cell and motor supplied by Huaxing Group Company is about 1.5 million US dollars, and the military has confidentially purchased 20 sets, and advanced a deposit of 10 sets, and provided 30 million research and development funds, which shows that the military attaches great importance to this project.

Military helicopters equipped with fuel cells and motor drives have a great advantage in concealment, which is simply unattainable by similar weapons and equipment at this stage, because the turboshaft engine is the most important source of noise, after removing the engine noise, as long as you want to take measures to further reduce the noise of the rotor, you can reduce the noise of the helicopter to a very low degree, which has extremely great military significance for the troops to perform their tasks.

The market for military helicopters in Huaxia is not very big at this stage, but he is more optimistic about the prospects of this market, at least 20 sets of power systems can be supplied every year, and with the development of the domestic economy, the market for civil helicopters is also very large.

Yang Jie is not worried that his R&D funds on this are wasted, but he is still young and can afford to make less money now and make a lot of money in the future.

By the time Yang Jie flew to Yanjing, it was already the end of spring, and there was also a heavy snowfall in the north.

As soon as the heavy snow stopped, there was a very spectacular scene in the southern suburbs of Yanjing City, two hundred large buses lined up in a winding long queue from the highway intersection endlessly, and many people who saw this scene showed surprised faces-

The buses, painted in sapphire blue, are so quiet that you can't hear the engine noise at all, only a low humming sound, and the exhaust pipe is not exhaust at all, but water.

There was a tanker truck with a Scania logo in the long convoy, which was also very quiet without engine noise, and only the exhaust sound of air brakes and tire noise could be heard.

"Why can't these cars hear the engine and smell the exhaust?"

Pedestrians on the side of the road asked curiously.

"You don't know this, these buses are confirmed to be fuel cell buses purchased by Yanjing Bus Company from Zhongyuan Automobile Company, and the news was broadcast on TV some time ago. ”

A young man next to him pointed to the logo in front of the bus, "Look at the logo of this bus, it is clearly the logo of Zhongyuan Automobile Company." ”

"What is a fuel cell bus?" asked an old man curiously.

"In layman's terms, the bus does not use an engine, but is replaced by a generator that uses hydrogen as fuel to generate electricity, and uses electricity to drive the car. ”

"When will our country be able to produce such an advanced bus, this car is not cheap, right?"

"That is, such a high-tech bus, it is sure that it cannot be cheap. ”

……

This long convoy drove all the way, which also attracted the eyes of countless people and attracted many people's discussions.

In the afternoon, Yang Jie attended the handover ceremony of Zhongyuan Automobile Company to Yanjing Bus Company to supply 200 fuel cell buses, which was the largest single purchase.

The ceremony was held in the bus company's terminus, and many leaders of Yanjing City were present, and Chu Xionghuan of CNOOC was also talking to Yang Jie at this time.

"Yang Shao, Huahai Oil has almost built about 200 hydrogen oil filling stations in more than 30 cities, and now the country is vigorously promoting hydrogen energy, this market is very large, can your Huaxing Group Company supply fuel cell production capacity?" Chu Xionghuan asked.

In almost two years, CNOOC has invested in the construction of so many hydrogen oil filling stations, and has completed the layout in Central Plains Province and Chubei Province on the basis of completing the layout, and is now preparing to start the layout in first-tier cities.

"Our second-generation fuel cell technology has matured, and at the beginning of next year, we will use the authorized method to supply equipment and accessories to some domestic companies to these companies to start assembling and producing fuel cells, and the production capacity will be greatly improved. ”

Yang Jie said with a smile: "Now that our fuel cell cost has been reduced, we will start to launch a fuel cell of about 100 kilowatts installed in cars next year, and it is estimated that the market ownership of fuel cell vehicles will have a great increase in a few years." ”

Now the fuel cell production cost of Huaxing Group Company has dropped to nearly 100 US dollars per kilowatt, and the cost of stacks plus motors, inverters, power modules, and control systems has been controlled at 13,000 US dollars.

"That's great!" Chu Xionghuan said excitedly.

Although Huahai Oil has invested less than billions in hydrogen fuel filling stations in the past two years, but now these hydrogen oil filling stations are supported by enough fuel cell buses, and now the consumption of hydrogen oil is almost seven or eight billion per month, and Huahai Oil has achieved a profit of nearly 200 million yuan every month, and it will take less than a year to earn back the previous investment, and this is a business that will make a steady profit.

It's no wonder that CNOOC is now in a hurry to start a bigger layout.

Although Huaxing Group Company does not participate in corporate governance, Chu Xionghuan has to ask Yang Jie's opinion on making the company's strategic layout, especially the supply of hydrogen oil is controlled in the hands of Huaxing Group.

"Chu Dong, last month our electrochemistry laboratory has been greatly improved in hydrogen storage skills, hydrogen storage capacity has increased by 35% compared with the conditions, and now 100 liters of hydrogen oil hydrogen storage capacity can reach 10 kilograms of hydrogen, the cost of hydrogen oil is 20% lower than the cost of gasoline, which has a grand role in promoting hydrogen fuel cell products. ”

"Yang Shao, your skills are progressing so fast!" Chu Xionghuan said in surprise: "I think maybe in less than ten years, our country's energy structure will have very big changes. ”

He paused and said: "It seems that we Huahaiyou must speed up the pace of entering hydrogen energy, otherwise we will not be able to keep up with the situation at that time." ”

"Huahaioil is good at exploiting oil and gas fields, natural gas hydrogen production and coal hydrogen production are the most important and mature hydrogen production roads at this stage, the unit investment of natural gas hydrogen production projects is not very large, if the scale of hydrogen production, the cost can gradually approach the cost of coal hydrogen production. ”

Yang Jie said.

"Yang Shao's meaning is consistent with our company's goals. ”

Chu Xionghuan nodded and said: "Huahaiyou is also adopting the strategy of stabilizing oil and increasing gas, and will focus on the exploitation and processing of natural gas in the future. ”

Yang Jie also nodded, if a large state-owned enterprise like CNOOC enters the field of hydrogen energy, it will have a very big role in accelerating the energy structure of Huaxia.
