The next day, Yang Jie followed Zhang Dingkun to the Dalian shipyard where the Varyag aircraft carrier was located.

At this time, the Varyag aircraft carrier had entered the stage of transformation, and the behemoth that was dragged into the dry dock had been erected around it by this time, and it was covered with green gauze.

At this time, the entrance to the work area is guarded by armed police, and registration must be made when entering and leaving.

After Yang Jie followed Zhang Dingkun into a bus, the heads of the Dalian shipyard and the military were waiting there early.

Yang Jie, Zhang Dingkun and others then put on hard hats and walked towards the dry dock where the Varyag aircraft carrier was located.

At this time, Yang Jie saw a lot of equipment stacked next to the dry dock, noticed that it was some fuel cell power station equipment, and also noticed that the Varyag aircraft carrier had broken a big hole, obviously to stuff the fuel cell power station into it to replace the previous gas turbine power plant.

Zhang Dingkun also noticed it, and immediately asked the commander of the project construction.

"Chief, Yang Dong, we have now dismantled all the previous power systems, and then we will start to install this fuel cell power station. ”

Zhang Dingkun looked at Professor Ma Weimin on the side: "Professor Ma, this aircraft carrier can be equipped with a medium-voltage DC integrated power system and an electric propulsion technology system, you have made a great contribution!"

Ma Weimin said modestly: "This is mainly because Yang Dong's Huaxing Group Company provides such a high-power fuel cell power station and high-power permanent magnet motor, otherwise we would not have developed this system." ”

Yang Jie smiled: "Professor Ma is modest, we are providing subsystems in this regard, and it is more difficult to integrate these systems to maximize their efficiency." ”

Professor Ma Weimin is a top genius in the ship electromagnetic, on the basis of these system components provided by Huaxing Group Company, the medium voltage DC integrated power system and the whole ship electric propulsion technology have been developed, these two systems have been technically verified on a test ship of the military, and at the end of last year also passed the verification of the military, the performance is very advanced, and stable and reliable.

It was these two systems that passed the acceptance of the military, and the senior management decided to abandon the previous plan of using gas turbines as power, and chose a fuel cell power station as an increased power permanent magnet motor as the power system, and used the medium-voltage DC integrated power system to ensure the power supply of the whole ship of the aircraft carrier.

Among them, Professor Ma Weimin's technology patents in these years of research and development, Huaxing Electric Power Technology Company, a subsidiary of Huaxing Group Company, are also used in many power equipment.

Zhang Dingkun said with a smile: "Professor Ma Weimin is a genius in power system, Yang Jie, you are a genius in technology and business, you are a combination of two swords, pushing the navy's weapons and equipment to a very high level." ”

Everyone laughed along.

Yang Jie then followed everyone into the Varyag interior for a visit, at this time many workers inside were busy working, and there were flashing electric sparks and the sound of cutting and grinding everywhere.

The magnitude of this transformation is very large, the angle of the upturned deck is different, and the special deck above should be cut off and replaced with domestic special steel, for which the country should provide special steel and large hydraulic equipment and welding materials.

The formula of this special steel is provided by the Metallurgical Research Institute of Huaxing Group Company, and the welding consumables and equipment are provided by the Machine Tool Research Institute.

Part of the technical team of the Metallurgical Research Institute is from the metallurgical experts of Damao and Ermao, and there are also technical experts from domestic metallurgical research institutions, although the number is not large, but the technical strength is very strong.

Because the technical patents and formulas held by these metallurgical experts from overseas are related to their own income, these technical experts have come to the metallurgical institute after taking out their patented formulas, and the revenue of the metallurgical institute is transparent and open, these experts enjoy generous treatment while constantly developing new materials, because there is competition between different teams within the metallurgical institute.

Yang Jie also attended the meeting in the evening after visiting and inspecting the Varyag aircraft carrier, and the Dalian shipyard also reported the work progress to Zhang Dingkun.

At the meeting, Sun Shicong, the chief designer from Shen Fei, also reported the research and development progress of a carrier-based aircraft model, and also took out the appearance design drawings of the carrier-based aircraft.

Regarding the carrier-based aircraft for the domestic aircraft carrier, the military held a bidding for the design plan at the same time as the construction of the aircraft carrier, and Shenfei and Huake Aviation Technology Company both participated in the bidding.

In fact, the military is more inclined to purchase the J-15 fighter of Huake Aviation Technology Company, because the technical foundation of this aircraft comes from the F-14 Tomcat fighter, which is a ready-made carrier-based aircraft.

The carrier-based aircraft technology designed by Shen Fei comes from a Su-33 carrier-based test aircraft provided by Ermao, which is immature in all aspects, while the big Tomcat carrier-based aircraft has been in service on the aircraft carrier of Eagle Sauce for almost 20 years, and the navy has purchased more than ten improved versions of the Big Tomcat J-15 columns installed in the naval aviation unit, and now it has begun to enter the state of combat readiness.

The naval aviation unit is very satisfied with the performance of this fighter, because Huake Aviation Technology Company has increased the area of the main wing and composite pylons, and the original Tomcat fighter can only add six long-range air-to-air missiles, but now the load capacity is not worse than the J-11 load capacity, or even stronger, mainly because the engine power is more powerful.

The Air Force has also purchased a lot, and the Air Force is also very satisfied, and this fighter has successfully changed from export to domestic sales.

Since the reorganization of the four major domestic aviation development companies into China Aviation Development Group Corporation, the Taihang engine has finally matured, and now it is also developing a new core engine, but the progress is still very slow, mainly because the design experience of the engine is still very lacking in China.

The Yonghan Aviation Technology Co., Ltd., a subsidiary of Huaxing Group Company, has dug up a group of very experienced top experts such as Konstantin and Wang Yonglin and Liu Fuping for development very early, and has cultivated a backbone technical team of no less than 1,000 people over the years, and if you add a team of middle and senior engineers, there are almost five or six thousand people in the research and development team.

It is with such a number of R&D personnel that Yonghan Aviation Technology Co., Ltd. has continued to develop a variety of engines over the years, and the company's technical strength is less than ten years behind the overall technical strength of Pratt & Whitney, GE and GM, and it is even more powerful in monocrystalline high-temperature materials.

It is precisely because of this that the performance of the fighters launched by Huake Aviation Technology Company and Hongdu Group Company is very powerful.

This also caused a lot of pressure on Shen Fei, and the performance of the J-11 fighter equipped with Taihang engine was suppressed by Huake Aviation Technology Company and Hongdu Group Company, after all, the performance of Damao engine has been surpassed by Yonghan Aviation Technology Company.

However, in order to take into account the balance, the navy also rarely accepted two design schemes at the same time, which means to form a high and low combination.

At the same time, the military also encouraged Shenfei to increase the scale of exports and learn from Hongdu Group and Huake Aviation Technology Company.
