"Yang Shao, the position of our command station enclosure is close to the bow, which makes the rudder efficiency of the enclosure rudder higher, the vertical plane maneuverability is better, the height of the command station enclosure is lower than that of the previous model, and the positive and transverse area is also smaller than before, which is also the result of our many experiments, which has improved the underwater speed of the Yuan-class submarine and the sound concealment of the ship.

In addition to the improved sonar system, the Yuan-class submarine uses a new type of photoelectric detection mast in the enclosure of the command station, and is equipped with CMOS cameras, infrared thermal imagers, laser rangefinders and other observation equipment, of which the cameras and infrared thermal imagers are provided by the Huaxing Group Company.

All sonar, reconnaissance, radar, electronic warfare and weapon controls on board are also connected to a digitally integrated integrated control system.

After entering the interior of the submarine, Yang Jie also saw that the instruments and equipment inside were highly integrated, canceling a large number of traditional instruments and dense buttons, and finally caught up with the military electronic technology level of Western countries.

The submarine is now also a technical backbone sent by the military to be familiar with the operation of the ship, and the selection of submariners is second only to the pilot, who is not tall, and his skin is tanned, and he looks strong and strong.

However, what surprised Yang Jie was that the deputy commander of the submarine was more than 1.80 meters tall, a few centimeters taller than Yang Jie, and his body was more burly.

"Deputy Chief Liao, isn't it very inconvenient for you to get on the boat like this?" Yang Jie also asked the deputy chief surnamed Liao.

"Hehe, it was inevitable to cross the hatch at first, climb up and down and hit my head, but then I also mastered the skills, and when I crossed the door, I bowed my head and lifted my legs with one action. ”

This Deputy Commander Liao showed a mouthful of very neat and strong teeth when he laughed, and the other crew members were also in this situation.

Yang Jie later asked about this situation, and then he learned that the submariners had a very special requirement, that is, their teeth should be very neat and strong-

Submariners are able to hold on to their underwater missions or when they leave the boat, and if they get out of the boat, it will be very dangerous.

A new submarine like the Yuan class costs more than 400 million Chinese dollars, and each post may face some simple electronic display interfaces, but behind it is a series of high-tech, in order to understand these high-precision instruments and equipment, from the captain to the crew below are constantly learning, Yang Jie also noticed that these crew members have pen and paper and operation manuals in their pockets at any time.

Because of the installation of fuel cells and permanent magnet motors, how to repair and maintain the old business non-commissioned officers of the motor compartment and propulsion compartment must learn from scratch.

In addition, in order to improve the living space of the crew, Yang Jie also deliberately installed an air conditioning system in the Yuan-class submarine.

When the submarine is navigating underwater, the heat dissipation of each compartment is different, especially when navigating underwater in the southern sea area, due to the high outboard water temperature, the air temperature in this type of cabin can reach 40 degrees Celsius or higher, and the relative humidity can reach 90%~95% When navigating in the northern sea area, the cabin temperature can be as low as a few degrees Celsius, and when on the water, it can even be as low as zero degrees Celsius, and the ambient temperature and humidity that are too low or too high will seriously affect the health and work efficiency of the crew, and at the same time will have different effects on the whole life of the mechanical devices and electronic equipment in the boat.

Therefore, the air conditioning device of the submarine is a must, and it is also a guarantee of combat effectiveness.

The air-conditioning system keeps the temperature and humidity of each cabin in a very suitable range, and at the same time, the system separates the carbon dioxide exhaled by the crew, and the carbon dioxide reacts directly with the hydrogen stored after the electrolysis of water to produce water and methane, which is directly discharged from the boat, and the artificial water is used for water recycling or re-electrolysis to produce oxygen.

Other harmful gases, such as ammonia, hydrogen sulfide and dangerous gases produced by the work of the instrument, are completely filtered out, and the circulating gas produced by this device is close to the relatively clean air in nature, so that the air in the submarine is no longer hypoxic and choking.

Because the fuel cell can provide sufficient power, coupled with the replacement of the previous two sets of 320 batteries with supercapacitor batteries, each battery weighs 326 kilograms, and the maximum power can reach 4 megawatts in a short time.

That is to say, the fuel cells on the submarine do not need to run at full power all the time, as long as these battery packs are fully charged, they basically run at a very small power, and it is precisely because of such sufficient power that there is enough energy space for the submarine to be equipped with electrolytic hydrogen production devices.

At present, the 30,000 kilowatts of natural circulation nuclear reactors used by domestic nuclear submarines can only generate nearly 10 megawatts of electricity, and now the combination of fuel cells and supercapacitor batteries can exceed the power generation capacity of nuclear submarines in a short period of time.

The price of such a supercapacitor battery pack is more than double that of the battery pack used in the German 209-class submarine, and now the cost of the supercapacitor battery provided by Aode Technology has dropped to $500 per kilowatt, which is four times lower than the price of $2,000 per kilowatt a few years ago, and now the volume is smaller than the lead-acid battery, and the capacity is about 10% more.

In recent years, the use of supercapacitor batteries in various fuel cell power packs has greatly reduced the cost, and the industrial scale and technical strength have also surpassed those in Europe and the United States.

At present, a lot of research and development has been done on the safety of supercapacitor batteries provided by Aode Technology Co., Ltd. to prevent supercapacitors from catching fire when they are short-circuited, which greatly improves the safety performance.

And now the rate of technological advancement in batteries is much slower than that of supercapacitors, and the price of batteries with the same capacity for the same amount of time has basically dropped very little.

Although the price of the battery is more than twice as expensive, the military is very satisfied with the performance of this battery pack, coupled with a set of electrolytic hydrogen and air integrated system, it is also a hard to increase the cost of nearly 30 million, so that the cost soars to 410 million compared with the previous 370 million quotation!

This offer is already the most expensive conventional submarine in China, but compared with the price of $90 million per Kilo-class submarine imported before, this price is acceptable to the domestic military.

Honghu Shipyard also attaches great importance to the order of the third-generation submarine of the Yuan class, because the previous submarine orders were insufficient, and the engineering and technical personnel in the factory were very weak, which was also the reason why the quality had been problematic before.

In order to solve this problem, Honghu Shipyard also sent a group of technical backbones to the Machine Tool Research Institute for further training, and also transferred a group of engineering and technical personnel from Huaxing Group Company to support, which ensured that the quality control quality of the Yuan-class submarine reached a very high level.

Since the beginning of the education reform more than 10 years ago, the system of training skilled workers is basically gone, and now it is difficult to find skilled mechanical and electrical skilled workers in the society, Yang Jie has long been aware of this problem, so he has already signed a contract with many vocational colleges and universities in Central Plains Province and Chubei Province, these colleges and universities have made changes in accordance with the needs of Huaxing Group Company in the content of education, and students will be arranged to train and practice within the company every year, Huaxing Group Company will get a group of engineering and technical personnel with relatively high quality in all aspects every year, and the company's internal training content is a lot, and the speed of technology update is very fastThis also ensures that the level of engineering and technical personnel within Huaxing Group has always been maintained at a very high level.

Students in domestic vocational colleges and universities regard entering Huaxing Group as the first goal, especially to enter the Machine Tool Research Institute for further study is a dream goal——

Now the Machine Tool Research Institute is a palace-like existence in the eyes of all mechanical engineering technicians in China, and it is no worse than the reputation of these famous schools such as Yanjing and Ziguang University.

In recent years, many experts in the Machine Tool Research Institute and the Electrochemistry Research Institute have also published some professional books in this area, many of which have been used as teaching materials for major universities.

And the people who come out of the Huaxing Group will be coaxed by many domestic companies, because the technical level of the people who have received various training within the Huaxing Group is obviously higher than that of other companies.
