It is also Huaxing Group Company that has been accumulating technical strength in all aspects for so many years, and the outside world cannot directly see many aspects, but now everyone in the blue-collar circle is extremely convinced and yearning for Huaxing Group. ¥ ♀ Eight ¥ ♀ Eight ¥ ♀ Read ¥ ♀ Book, .2 ≠ ◆

There are thousands of expert engineers in Huaxing Group, more than 20,000 senior technical engineers, more than 50,000 intermediate engineers and junior engineers, plus a large number of physicists, chemists and mathematicians in Huaxing Group, these combinations enable Huaxing Group to quickly turn research and development technology into software and hardware products.

Now there are very few problems in mechanical and electrical engineering to stump Huaxing Group, which is also the real reason why Honghu Shipyard has raised its manufacturing level to a very high level in a short period of time.

Previously, these conventional submarine forces were very envious of the nuclear submarine force's air integrated system, but this time this Yuan-class submarine was Yang Jie's insistence on modifying the design drawings and adding this system to it, for which the construction of this submarine was stalled for several months, and it was only launched two months ago.

In addition, Yang Jie also installed a set of intelligent adjustable lighting system in the submarine, when the submarine dives into the water, it may not see daylight for several weeks or months, change the light level, change the color temperature from warm to cold and then to warm, which can simulate natural daylight and help adjust the biological clock in the submarine.

The crew members who participated in the training were extremely satisfied with this, and the captain and deputy commander all grabbed Yang Jie's hand and thanked him repeatedly.

This Yang Shao attaches great importance to the details of the lives of officers and men at the grassroots level, and uses technology to change the living environment of officers and soldiers, which is quite different from the leaders and brains of the military.

"Hehe, I am now one of the bosses of the Honghu Shipyard, and the officers and soldiers of the army are our customers, and we try our best to meet the needs of our customers what they need. Yang Jie said with a smile.

Everyone laughed.

Later, Yang Jie also inspected an indoor slipway salvage ship under production, which has completed the laying of the keel of the 4,500-ton salvage ship. →??? Eight +++ Eight ** Read == Book ^^≥

This is a special vessel for salvaging rocket wreckage in the deep sea, and the deep-sea salvage submersible for the ship is also under construction, this submersible is jointly developed by Huaxing Group Corporation and Ship Design and Research Institute, and the sketch is provided by Yang Jie.

In the workshop, Yang Jie also saw part of the shell of the submersible and a titanium alloy manned ball being processed.

This titanium alloy manned ball was welded like a watermelon petal in the past, but this time the Machine Tool Research Institute in order to reduce the weld, like processing two hemispheres, and then welding them together.

Now the weld in the middle of the welded manned ball is still obvious, and then it will be inspected for flaw detection, polished and polished, and sent to the pressure tank to undergo a high-pressure test to see if it can withstand the pressure of 6,000 meters of deep sea water.

Not only the manned ball, but also the pressure-resistant shell of the submersible are stamped and welded by high-quality titanium alloy materials provided by the metallurgical plant of Zhongyuan Automobile Company.

The submersible weighs almost 18 tons, and how to make the density of this submersible close to the density of seawater, and be able to move easily at different depths, requires a very special solid buoyancy material.

Previously, the core technology of this solid buoyancy material was in the hands of foreign companies, and this material was prepared by hollow glass beads, millimeter-level hollow plastics, millimeter-level hollow glass spheres, and high-strength resin, which could not be bought with money.

Tianma Technology Co., Ltd. is first-class in the preparation technology of microspheres, and this time it also undertook the research and development task with the Institute of Electrochemistry and other R&D departments, and it took almost a year to explore the process of this set of materials.

In order to prepare this material, Huaxing Group Company used almost more than a dozen tons of glass beads, which also met the production task of producing two submersibles.

These materials are also partly used in automobiles, mobile phones and airplanes, and the previous R&D investment has been earned back in half a year.

Yang Jie opened five observation windows for the manned ball, the glass thickness of these observation windows reached 125 mm thick, and the whole is cone-shaped, so as to ensure that it is not easy to enter the water under the condition of high pressure on the seabed, because in the formal mission, the observation window glass of the submersible needs to withstand about 450 atmospheres of pressure in the underwater working environment, and the three sunshine science factory has also developed a special glass material for this purpose, and the glass sent over has undergone various tests in high pressure and high temperature and corrosion resistance and waterproofing, and it was sent over after meeting the requirements.

In addition, the two submersibles are also designed with adjustable pressurized water tanks and seawater pumps.

The shape of the water tank is like a peanut shell, and the water in it can be adjusted by a seawater pump, because the submersible designed by Yang Jie has to grab hundreds of kilograms of objects with a robotic arm on the seabed for thousands of meters, and in order to maintain the submersible's underwater zero buoyancy state, the seawater pump must pump out hundreds of kilograms of seawater from the pressurized water tank.

If the seawater will be pumped out at a depth of thousands of meters, this seawater pump must be an ultra-high pressure pump, and the machine tool research institute will also use the imitation and improvement of the metal diaphragm compressor.

In addition, Huaxing Group is also equipped with several sets of high-definition digital cameras for the submersible, which can be observed and photographed from different angles, and the pilot inside the manned ball can judge the situation outside the submersible more clearly.

The two manned submersibles have a total of six horizontal and vertical thrusters in various directions, with the stern thrusters producing 20 kilowatts and the flanks producing 5 kilowatts.

The low-power shaftless pump thrust product built by the Machine Tool Research Institute for the Naval University of Engineering has been tested for more than two years, and the performance has stabilized in all aspects, according to the theory, the maximum underwater speed of the submersible can reach 15 knots!

Powering the submersible is, of course, a 100-kilowatt fuel cell and a supercapacitor battery, as well as a 150-liter hydrogen fuel tank that will allow the submersible to work on the seabed for several days.

The School of Robotics of Meixihu University has designed a set of very flexible manipulators for this purpose, and the robotic arm is provided by the Machine Tool Research Institute.

The driver inside the manned ball can control the outside robotic arm and manipulator by wearing a bionic manipulator, and this control system also incorporates a force feedback system.

This system is also the result of research and development of Meixihu University for so many years, and now the bionic manipulator has been able to make some very complex movements, and the force feedback system is also relatively accurate, and the manipulator will rarely crush the egg when grasping the egg.

Several kinds of manipulators trial-produced by the Robotics Research Institute of Meixihu University are now able to play table tennis and pen turning games more skillfully, as well as complex actions such as throwing objects and tying knots with one hand, which are super fast and accurate.

Now Meixihu University has sent a set of table tennis sparring robots to the table tennis national team for trial, and this set of robots has also become the star of the national team, and is also nicknamed the "magic hand", because this guy is too fast, many team members are a little unable to react.

Yang Jie designed and built these two sets of submersibles to salvage the wreckage of the first-class rocket, and the manipulator had to fix the rope to the rocket shell very precisely, which was too poor to be accurate.

In addition to the robotic arm and manipulator, the air pressure inside the submarine is maintained at a constant atmospheric pressure, and the air circulation inside is similar to that of the space shuttle, using lithium hydroxide to remove the accumulated carbon dioxide, and the life support system in the submarine can maintain a single person for hundreds of hours, and a team of 3 people can also reach about a week.

The connection between the submersible and the sea surface is a VhF radio and is equipped with a 250-meter range video sonar device, which can display images of nearby objects and measure distances. It is also possible to measure the distance from the seabed when approaching the seabed, and it is also equipped with a set of laser mapping radars, which can be synthesized to obtain a 3D digital map of the high-definition topography of the seabed.

This kind of accurate mapping of the seabed can be carried out through sonar, radar and other devices, and the system can obtain decimeter-level vertical resolution during the test, which also means that the manned submersible has the ability to search for dangerous targets underwater.

In addition, there is a set of underwater positioning equipment, which allows the submersible to accurately locate and continuously transmit positioning information to the surface mother ship. 11
