Development of productivity started in 1981

Chapter 262: The Canglong large carrier rocket is successfully manufactured and launched at an appropriate time
Wang Jiankun stood on a small hill in the small town of Katongani and looked to the south, where there was a vast blue ocean.

The weather was clear and several small islands in the outer sea were vaguely visible in the morning mist.

There are already many fishing boats fishing at sea.

Most of them are small fishing boats with iron frames and wooden hulls. They dare not sail too far and only wander around the mouth of the Irrawaddy River to fish. Only a few steel fishing boats under the Four Seas Fisheries are fishing in farther and deeper places, where the fish are bigger.

After several days of investigation and visits, Wang Jiankun discovered that this was indeed a suitable place to build a large space launch base.

First of all, the foundation is relatively solid.

After removing the 2-meter-high layer of loose soil in an area of ​​30 square kilometers around the hill, the hill will be blown up, and the rocks can serve as filler for the lower layer.

In this way, the area of ​​the entire main launch site will reach 3 square kilometers.

This area is enough to build 3 to 4 large transmission towers and supporting facilities.

Secondly, there are few people living around here, and it will not affect the main channel, because the hill is on the side of the peninsula far away from the Irrawaddy River, about 8 kilometers away. At this distance, even if there is danger at the launch site, it will not affect the ships entering and leaving the Irrawaddy River.

Finally, there are only a few small islands with low altitudes in the southern part of the peninsula, and further south is the endless sea.

In the future, when large carrier rockets are launched, they will fly southward over the equator, and the first stage will only fall into the sea, not onto land.

After he finished the survey, he gave the topographic map of the town of Katongani that he had explored using his superpowers to Sophon on the spot, and asked him to design and plan it according to the standards of a large-scale space launch base.

When he boarded the ship from the dock in the small town of Katonggani and was halfway to the Yangon Shipyard, Tomoko had completed the design of the entire space launch base and thoughtfully made the scene animation.

He carefully reviewed Chieko's design on the ship. It was indeed perfect, taking into account everything he had thought of and not thought of.

The entire main launch site was built on the original site of a hill that was flattened. The first phase of the project is a comprehensive launch site. The launch tower can support rockets of different specifications ranging from 2 meters to 8 meters in diameter.

In addition, an assembly plant has been set up about 2 kilometers away from the dock.

In the future, rockets manufactured at the Yangon Rocket Manufacturing Base will be divided into several sections and shipped to the assembly plant at the port.

After the rocket completes vertical assembly at the assembly plant, it will be transported to the launch position of the launch tower via a heavy-load railway of about 3.5 kilometers.

Then various fuels are loaded there and wait for launch.

The second phase of the project is to build two dedicated launch sites.

One is used to test the recoverable launch vehicle. It has no launch tower, only the American launch pad.

The other is a launch site for solid rockets, used for rapid launches.

Because Wang Jiankun had not yet made a final decision on the third phase of the project, only the corresponding site was reserved.

After reading the design, he looked at the construction plan and workload, and found that in order to complete this first phase of the project, a large amount of large-scale construction machinery and corresponding engineering personnel would need to be dispatched.

Fortunately, after more than a year of construction, the large-scale engineering equipment manufacturing plant in the old base has been completed and has begun to produce some engineering machinery.

There is a severe shortage of construction workers. The Miyang Railway is still under intensive construction, provincial and national highways across the country are also under intensive construction, and various factories are also being built in various places.

Therefore, the engineers needed for the construction of the space launch site can only rely on himself to create a group of new human engineers.

After reviewing the design drawings, he sorted them into different levels of confidentiality and uploaded them to the central computer.

Some preparatory work can be started first, such as the removal of earth from the launch site, the construction of infrastructure roads, and the expansion of the dock.

When he arrived at the Yangon Shipyard, the Myanmar Ministry of Foreign Affairs had already established an aerospace engineering working group within the ministry, with his uncle Cen Yong as the group leader, responsible for coordinating the support of various departments for aerospace engineering.

The working group members read the relevant materials one after another, and then passed the tasks down one level at a time.

Responsible for helping to allocate resources such as cement, sand and gravel, giving priority to aerospace engineering construction work.

The person in charge of steel and nonferrous metals distributed the tasks to various factories. For example, Gaoya Steel City was responsible for specially producing a batch of super-heavy steel rails for the rocket transportation tracks of Gatongani Space City.

The three super-large railway transport platforms have a static load-bearing capacity of 3 tons and can withstand the impact force of a 5-ton rocket taking off.

The heavy engineering equipment manufacturing plant is responsible for manufacturing super-large rocket transport vehicles. The length of a single vehicle must reach 80 meters, the diameter of the transported cargo must reach 8 meters, and the carrying capacity must reach 800 tons. The internal code name is "three eights".

The Ministry of Chemical Industry issued the manufacturing requirements for various fuels to the factories that were being put into production one after another, asking them to complete the trial production as soon as possible according to the process, and to expedite the production of a batch for the launch of test rockets after the tests were qualified.

The communications department delegated the manufacturing of communications equipment used in various aerospace projects to the Northern Myanmar branch of Xingyao Group.

There, the most advanced 0.5-micron lithography machines will manufacture the latest aerospace-specification chips for rockets.

……

Wang Jiankun's visit to the Yangon Shipyard was not long. He mainly came to see the technical level of the workers here and whether the shipbuilding equipment could support the manufacture of a variety of specialized ships.

After looking around, he decided to use his superpowers to add some senior engineers and automated equipment to the shipyard.

Under the leadership of the military government, the Yangon Shipyard had a very low level of technology and could only manufacture small boats of 3 or 4 tons. It had never built any larger ships.

Before deciding to launch the war of unification, the Quanjiezhen began to invest in the shipbuilding industry and purchased a number of advanced equipment from countries with first-class shipbuilding capabilities such as the United States and Japan.

However, due to concerns about the military government, the equipment arrived shortly before the war of unification.

Large-scale investment began only after the war of unification ended and the shipyard was taken over.

However, infrastructure projects are very time-consuming, and the initial stage mainly involves building larger docks and larger lifting equipment.

It was not until the beginning of 85 that qualified engineers began to move into the shipyard and began to build larger ships.

They started with a 3-ton bulk carrier and built a larger ship every two months.

It was not until the end of 85 that the keel of the first -ton ore carrier was laid.

After Wang Jiankun chatted with the person in charge of the shipyard for a long time, he basically understood the manufacturing capabilities of the shipyard at that time.

If we don't add a new group of senior engineers and a batch of better-performing shipbuilding equipment, it will take at least three years to manufacture rocket transport ships, special rocket fuel transport ships, and space tracking and control ships.

This is assuming that there are no problems with the shipbuilding technology and drawings provided by Wang Jiankun and that the construction goes smoothly, otherwise it will take even longer.

So after inspecting the shipyard, he took a special plane from Yangon Airport to the Ningdiben base.

There, he asked Tomoko to look up information about several shipyards in Japan and South Korea at that time.

Then, Zhizi made some improvements based on his experience on several equipments that can improve the efficiency and quality of shipbuilding, such as welding machines, 3D full-freedom bending machines, and CNC cutting machines.

A variety of laser measuring instruments have also been designed to improve measurement accuracy.

After using his super powers to manufacture these devices, he created a team of 120 senior engineers in the medical center.

This group of engineers was specially prepared to build several types of ships dedicated to aerospace engineering.

They took a large number of advanced shipbuilding equipment and boarded a C-800 transport ship, starting from the upper reaches of the Irrawaddy River and sailing downstream directly to the Yangon Shipyard.

After preparing talents and equipment for the shipyard, Wang Jiankun devoted himself to the manufacturing of the "Canglong" large carrier rocket.

The Soryu rocket was designed by Wang Jiankun with reference to the American Hercules rocket and the Soviet Proton rocket, and then with the help of Sophon and the assistance of rocket engineering designers.

Zhizi mainly played the role of error checking and design program development and maintenance.

The specific parameters of the "Canglong I" rocket are as follows.

Spacecraft I does not have boosters on the sides, only the core stage in the middle.

The core stage is a 3-stage rocket.

The first and second stages use liquid oxygen + kerosene fuel, and the third stage uses liquid oxygen + liquid hydrogen fuel.

First stage: 4 Gangau (Northern Myanmar Mountains) class engines, thrust 2 kN (sea level), burning time 800 seconds.

Second stage: 3 Gangao engines, thrust 820 kN (vacuum), burning time 210 seconds.

Third stage: 1 Minjin (Northern Myanmar Mountains) engine with a thrust of 120 kN (vacuum) and a burn time of 600 seconds, and 4 attitude engines with a thrust of 5.2KN for attitude control.

The diameter of the first level is 4.8 meters, the diameter of the second level is 3.6 meters, and the diameter of the third level is 3.6 meters.

The take-off mass is approximately 750 tons.

Carrying capacity:

Low Earth Orbit (LEO): 20 tons

Geosynchronous transfer orbit (GTO): 6.1 tons

There are also Canglong II and Canglong III.

The Soryu II is a model that has two solid rocket boosters bundled together.

Based on the Soryu II, the third stage of the Soryu III will try out nuclear engines to carry out deep space probe launch missions.

There is also the "Tyrannosaurus Rex", which uses the same engine as the Canglong, but its shape is very special.

The first stage below is a booster with 12 engines in parallel, with a diameter of 8 meters. The second stage above uses 6 engines and can be started multiple times and adjusted in attitude. The third stage can be installed depending on the different mission options.

The Tyrannosaurus Rex class consists mainly of the first and second stages at the bottom, which will be tested as a platform and will undergo recovery tests.

If the recovery test is successful, it will carry out launch missions of super-large spacecraft such as large space stations, lunar landers, solar probes, Pluto probes, etc.

With his and Tomoko's constant participation and guidance, the design work was completed in less than three months.

At this time, the engine manufacturing plant was also completed after intensive construction.

He brought engineering and technical personnel, used various mechanical equipment and conventional methods to manufacture the Gangao rocket engine and the Minjin rocket engine.

Although it is a high-end aerospace rocket engine, the equipment used in its manufacturing still relies on basic processes such as turning, milling, grinding and welding.

With the support of a large 5-axis CNC machining center, the large-sized super fuel pump is formed in one piece.

The 5-axis machine tool can turn and mill the titanium alloy steel billet after forging by a 3-ton hydraulic press in all positions with one clamping.

Such a 5-axis machine tool eliminates the errors caused by multiple clamping.

The cutter head, which rotates at a speed of up to 3.6 times per second, can complete the processing of the workpiece from different angles while rotating the other four axes.

If a 3-axis or 4-axis machine tool is used to process such a complex curved workpiece, the processing time may be as long as more than 2 months.

But in this special 5-axis CNC machining center, once the workpiece is clamped, the equipment can work day and night and complete the task in just 3 days.

In order to speed up the manufacturing of rockets, Wang Jiankun used his superpowers to manufacture more than 20 of these 5-axis CNC machining centers.

Titanium alloy and aluminum alloy blanks are brought in one by one, and after an hour or up to three days, the completed workpieces are clamped out by robotic arms or transported out by conveyor belts.

After processing, the parts are taken away by the testers and taken to the high-precision measuring room for comprehensive measurement.

After more than a month of intensive manufacturing, a total of 1 Gangao engines and 8 Minjin engines were produced.

Wang Jiankun asked the testing team to take one each and conduct tests on the upgraded rocket engine test bench.

Another seven Gangau engines and one Minkin engine were sent to the rocket manufacturing plant in Yangon to organize the first rocket.

At this time, the Yangon Rocket Manufacturing Plant was completed with the cooperation of more than 3 engineers.

The entire manufacturing plant is divided into 3 large workshops.

They are responsible for the assembly of the 1st to 3rd stage rockets respectively.

The rocket's aluminum alloy shell, fairing and fuel tank were manufactured at Magao's large box manufacturing plant, where Wang Jiankun helped to manufacture large-size plate bending machines, full-freedom 3D bending machines, carbon fiber forming machines and other professional equipment.

These devices were modeled after the rocket manufacturing plants in the United States and the Soviet Union, and then Zhizi automated them and improved their accuracy as much as possible.

On August 86, 8, the 1st to 1rd stage aluminum alloy shells, internal fuel storage tanks, cryogenic pipes, fuel pumps, engines, and fairings of the Soryu rocket were all delivered.

The Yangon Rocket Factory immediately began assembly work.

Since the equipment used in the manufacturing stage is of extremely high precision, after manufacturing is completed, various testing methods also ensure that the dimensions of these parts are within the design tolerance range.

Sophon has even designed a tolerance combination simulation program, which allows factory engineers and designers to adjust the tolerances of the next process or subsequent workpieces based on the real-time updated dimensional errors of manufactured workpieces, in order to offset the tolerance accumulation that causes the main body of the rocket to exceed the tolerance standard after the final assembly.

While various parts were being transported to the Yangon factory for rocket assembly, good news also came from the engine test bench.

Both engines achieved their design goals, and after combustion tests, they exceeded their expectations by a lot.

For this reason, Wang Jiankun changed some redundant designs when manufacturing the third batch of engines, reducing the weight of the engine and fuel pump again.

In this way, as the rocket was assembled, new engines of different designs were constantly manufactured.

These first few batches of engines are being tested successively to prepare power reserves for more types of rockets in the future.

On September 1985, 9, the first Canglong I rocket was assembled at the Yangon Rocket Factory.

Song Yumin, director of the Institute of Aerospace, excitedly reported to Wang Jiankun on the phone.

In the vision shared by Song Yumin, Wang Jiankun also saw the real Canglong I rocket.

Maybe it's because we're indoors.

The Canglong I looked exceptionally large.

At this point it was erected for static testing.

Painted in cyan, it stands out particularly in the bright white factory.

It is like a real dragon, ready to fly into the sky at any time.

Static testing is very important and the whole process lasted half a month.

During the period, pure water was used to simulate rocket fuel and the rocket was subjected to fuel loading tests.

After a series of tests, it is now fully capable of launching.

Wang Jiankun then reported the situation to the space work leading group and asked them to agree on a specific launch date.

王建昆为他们提供了9月25号，9月28号和9月30号这3天的不同时段供他们选择。

These three days are the time window that is more suitable for launch, calculated by combining weather forecasts and data such as celestial movement.

After several rounds of discussions, the aerospace work leading group informed all middle and senior management of the Quanjiezhen and decided to set the date as September 9.

Although it would be best if the launch was successful on September 9, the second anniversary of the establishment of the new government formed by the National Liberation Front.

But everyone is afraid that the first launch of such a large carrier rocket will fail, which will bring bad effects.

So the final launch date was set at 9:25 p.m. on September 3th at the earliest.
