"good! Thank you! " Zhang Brigadier once again extended his big hand to Zhao Lei to shake hands and say goodbye.
The experiment was very successful, and Brigadier Zhao was also very relieved, so he allowed Zhao Lei to go first. After all, they were not soldiers and did not always participate in righteousness.
In the next few days, we will also experiment with 3 thousand kilometers and the farthest 5 thousand kilometers. If they are successful, this national defense will be announced to be put into operation, and several national defense will continue to be built to protect the frontier of the motherland from foreign enemies

On November 2, 2011, Guangzhou Shipyard carried out the first intelligent manufacturing in the field of heavy industry in human history.
With Mo Qingying’s order, two yachts called submarine are automatically controlled from the cutting of the first steel plate to the forging of the 10,000-ton oil mold to form the irregular curved surface of the hull.
Then there is trimming, which is a necessary procedure before the welding process, but Guangzhou Shipyard is a little different. The welding edge is trimmed into a 45-degree inclined plane and needs to be finely polished.
This is, of course, the first reason why the welding is stronger. This is a new type of cold welding technology developed by the Institute of Materials.
No one really knows what this welding is called. It is called cold welding because there is no heat estimation in the welding process.
This is a technology of controllable excitation of microscopic magnetic field. When two welded surfaces are joined together, the original activity is enhanced and then fused with each other to achieve the purpose of welding.
The advantage of this kind of cold welding is that after welding, it is like a whole steel plate without a trace of welding and will not produce metal stress, so the ship’s shell will not be deformed.
Intelligent manufacturing of heavy industry is not to completely eliminate labor, but to replace manual operation of technicians with intelligent automation of important processes that affect quality, which can effectively reduce human errors and produce high quality.
For example, welding technology and all kinds of welding should be automated as far as possible, such as shipbuilding. At most, welding affects the quality most, and welding can solve this problem, which can greatly improve the shipbuilding capacity and ensure the quality.
However, there is a characteristic of heavy industry that the parts to be processed are too big, and the former fixed intelligent manipulator can not solve all the problems.
So Zhu Jun led the scientific research team to make bold innovation on the original intelligent mechanical foundation and developed an intelligent industrial robot that can walk by itself.
This is the greatest innovation in the history of human industry, and ordinary people may not understand the technical difficulties in vain.
Its first problem is to solve its own path judgment problem. With the intelligent transport vehicle technology, it is not difficult to solve this problem, but it is further complicated, from the original plane movement to three-dimensional walking
The most difficult thing is the three-dimensional three-dimensional positioning problem. The robot is not motionless, but it is constantly moving. Then it must first position itself at any time, and then position and observe the parts to be processed.
In other words, it must have a strong positioning system, a visual observation system and a strong artificial intelligence judgment mechanism.
There has been no such industrial robot visible for 21 years, which is indeed a great technological development.
If the robot can move by itself, it can solve many problems, for example, the installer of important equipment in the cabin can’t carry it, and the installation and debugging are very time-consuming, but the industrial robot is just doing things backwards, fast and good.
Guangzhou Shipyard has a long history and was founded in 151. It is a large state-owned enterprise under the banner of the Science, Technology and Industry Committee for National Defense, located in Changxing Island next to Huangpu Military Academy.
In front of Guangzhou shipyard is a military shipyard, which can build submarines, small and medium-sized surface ships and other warships.
However, two years ago, the state decided to suspend the construction of the navy, which made it difficult for the civil shipbuilding technology. It was not comparable to those flexible and convenient civil shipyards, and China and Europe became hostile. The foreign orders of the shipbuilding industry in the whole country were greatly reduced, which caused it to fall into a state of suspension for a time.
It was at this critical moment that Dolphin Technology decided to enter the shipbuilding industry, so it invested heavily in the acquisition of Guangzhou Shipyard.
The board of directors of Dolphin Science and Technology sent the first team from Mark to the shipyard to carry out drastic reforms, dismissed the original shipyard management department and greatly reduced the workforce, leaving skilled technicians.
At the same time, a team of intelligent factory research institute led by Zhu Jun was sent to the shipyard to stay with a team of technicians to study and improve the intelligent transformation project of factory shipbuilding equipment.
In addition, the infrastructure such as the shipyard workshop was renovated and improved to build dolphin technology standards for employees, and Mo Qingying led some dolphin real estate workers to the shipyard.
After Mark completed the integration of the shipyard management technicians, he had to return to Ying Software Research Institute, so the board of directors of the company asked Mo Qingying to be the general manager of this important company.
That’s why Mo Qingying ordered it, and now she has become the general manager of Guangzhou Shipyard.
This new submarine yacht is a small yacht with a displacement of only about 50 tons, which was designed with the help of Liu Meijuan’s intelligent brain.
It has two major innovations. The first is that it can dive into 1 meter offshore waters to visit the underwater world.
Secondly, it makes a small jet ramjet look very different.

Chapter 396 Big plane
Of course, this is still very different from the ordinary jet engine. This is the newly established Institute of Aerodynamics of Dolphin Technology. This yacht has specially developed a new engine.
First of all, it has no heavy spindle and complicated compressor turbine blades. Strictly speaking, it is a scramjet.
However, it is different from the scramjet of the rocket. It doesn’t have its own oxidant. After all, it is a yacht that doesn’t need that much power.
It also needs to balance the performance and cost. If it can be simplified, it can be simplified as much as possible. If it can be reduced, it can be reduced as much as possible. It even cancels the external bypass of aero-engine
The outer surface of the main duct distinguishes the cooling of circulating water. Because the temperature of the combustion chamber of the main duct is too high, the external cooling water will vaporize instantly to generate high-pressure water vapor, which will drive the impeller of the generator to generate energy.
This new type of engine is really a mixture of steam engines of jet engines, one engine and two engines, which can not only give driving force to ships, but also generate power, thus omitting a set of huge engines.
Generally, ships need to be equipped with diesel engines. The main reason is that the main power department can’t drive the propeller.
This design of Liu Meijuan solves this problem well, which not only saves energy, but also effectively reduces the weight and volume of the engine compartment. It has many advantages.
