Start with a blacksmith shop

At this moment, there is a turbojet engine 90 centimeters long and 29 centimeters in diameter placed on the shelf in front of him.

Compared with a real aircraft engine, this engine can be said to be very small.

But compared to the micro-turbojet used on model aircraft, this engine is much larger.

How big is the average micro engine? The total length is about 25 centimeters, and the net weight is close to two kilograms.

And how much thrust does the micro-turbojet have? It's about 12 to 15 kilograms.

The one in front of him was different. It was 90 centimeters long and had a total weight of 120 kilograms. And what about the thrust? That’s 1.4 tons!

With data like this, it has already left the ranks of model aircraft turbojet engines.

Compared with the micro-turbojet used on model aircraft, this is a huge difference. One's thrust is still in the kilogram level, while the other has already entered the ton!

The two engines he built can produce a thrust of 2.8 tons, and the overall aircraft he designed is only 3.5 meters long.

How long is the pineapple of a VW? Four meters! The weight is 1060 kilograms. A single engine can carry a small pineapple into the sky. You can imagine how powerful this engine is.

His model aircraft is 3.5 meters long, and its final total weight will definitely not exceed 1.2 tons. The two units have a total thrust of 2.8, and the aircraft can also be equipped with 1.6 tons of other things.

Once the engine is built, it must be ignited and tested. Although it has been tested in the laboratory, it still needs to be tested in reality.

Since he didn't have a test bed, he had someone build a simple one in the summer town factory area, on an open space where nothing had been built yet.

Eight-meter piles were driven below the ground, and a two-meter high platform was built using the highest-grade concrete on the ground.

There is an erected floor scale on the high platform, and the thrust that the engine can produce is shown by this floor scale!

This is the simple test bench built by Li Zhenhua himself.

After the simple test bench was built, he called Liu Xiaodong, who was at home, to the workshop to help.

The two people reasonably loaded the engine, which weighed more than 200 kilograms, into a small truck that had taken anti-shock measures, and then headed towards the test bench.

When Liu Xiaodong saw this cylindrical engine, he accepted it calmly because he was used to it.

Ever since the three of them came back from the military museum, Li Zhenhua in his eyes had been working hard on the aircraft engine. The first time he made a radial engine, and then he made a white tiger motorcycle.

Even if what he got this time was a turbojet engine, he wasn't too surprised. Instead, he was very happy.

Fortunately, what he was doing was a turbojet engine. There was no market for this thing in the civilian market, so he didn't have to worry about how big of an impact it would have on him.

The two came to the open space of the test bench and hoisted the engine to the test bench through the inverted chain.

Fix the iron chain connecting the weighbridge and the engine, and after all preparations are done,

Then he pushed a barrel of aviation kerosene to the test bench, inserted the oil pipe directly into the oil barrel, and manually pumped some oil into the engine.

Now that all the preparations have been done, the only thing left is the ignition test.

Under Liu Xiaodong's gaze, Li Zhenhua started the small turbojet engine in front of him.

As the engine began to operate, the engine emitted the unique scream of a turbojet.

As the fuel is injected more, the tail flame of the engine's tail nozzle is also lengthened!

The tail flame also started from red, slowly changed to orange, and finally formed a blue tail flame.

When you see the blue tail flame, you know that the temperature inside the engine has exceeded two thousand degrees.

During the observation, the engine ran very smoothly. After the oil was increased to the maximum, I started to look at the data displayed on the scale.

1400KG.

When seeing this displayed data, Li Zhenhua also had a smile on his face.

Liu Xiaodong, who was following him, also came over. Seeing the data above, he didn't understand him, so he searched the Internet to find out what level of thrust 1.4 tons was.

After such a search, he also knew what the thrust-to-weight ratio was. Thinking of the engine weight he had obtained before, he calculated that the thrust-to-weight ratio reached 12!

Then I searched for China's highest level Fo-22 fighter jet. The thrust-to-weight ratio of this engine is between 10 and 11.5.

Compared to the 12 in front of him, it actually had a higher thrust-to-weight ratio than the F119, which made him feel horrified.

From this aspect, it also shows the extraordinary power of this small engine!

After Liu Xiaodong learned something, he leaned towards Li Zhenhua.

"Zhenhua, tell me the truth, what are you planning to do?

Years ago, the list you gave me included both a furnace and a photolithography machine. You were overdoing it!

Just looking at the engine in front of me, I knew it was not simple. I just searched it.

The thrust-to-weight ratio of this thing has reached 12. This is 12. It is higher than the thrust-to-weight ratio of the Ford 22 engine.

What are you going to do? "

Liu Xiaodong's question was not clear to him amidst the screeching sound of the engine, but looking at the expression on the other side, he could make a rough guess.

Instead of answering him immediately, he calculated the fuel consumption.

Seeing that it was consistent with the data obtained in the previous laboratory, he then reduced the injection of oil and slowly stopped the engine.

While they were testing, the screams from the engine had attracted the attention of most people in the factory.

Everyone saw the strange high platform that was more than two meters high, and they also saw the cylindrical thing placed on the high platform.

Li Zhenhua came to Liu Xiaodong's side and sat down directly, regardless of whether the floor was dirty or not.

He patted the loess land next to Liu Xiaodong and motioned for him to sit over.

After he sat down, he said: "I didn't plan to do anything. I just came into contact with the Buddha 14 when I went to the Maple Leaf International Air Show last time.

And I sat in the cockpit of the Fo 14. As for driving it, it was a luxury.

After I come back, I want to build a model airplane to play with. At that time, I will install a 360-degree lens on the model airplane and make the ground console better.

Wouldn't that be able to realize my idea of ​​flying a plane? That's what I thought, just for fun, no other ideas! "

After hearing this, Liu Xiaodong didn't completely believe it. The engine was so awesome, could it be just for fun?

But he couldn't do anything about it. Who let others be the boss?

The engine also completely cooled down while they were resting.

After the temperature is not that high, we work together to remove the engine from the test bench.

Returning to the manufacturing workshop, he took the trouble to dismantle the engine.

Check each part inside the starter one by one to see if there are any problems with these parts.

Upon inspection, all parts were within his expectations and performed very well.

After getting these data, a smile finally appeared on his face.

Now he can start making the second engine, which will be made faster than the first one.

Some of the parts have been machined before, which speeds up the process.

After the two engines are finished, the next step is to make the variable sweep wing casing of the aircraft model.

The design of this receiver completely copies the structure of the Buddha 14. Of course, some things have been changed.

Because he also has these doubts, if the casing structure of his model aircraft is discovered by the mold country, it is consistent with the Buddha 14,

I believe that the CIA in Bad Country will definitely try their best to get rid of him or get him to Bad Country.

The receiver parts are made of lightweight high-strength alloy, which is also a single-crystal metal alloy with a particularly stable structure.

Since discovering the benefits of single crystal alloys, the materials he smelted can be made into single crystals. Anyway, he is not afraid of the high cost!

He also worked day and night to make the aircraft model's receiver, and he took out all the parts.

After the casing is completed, it is time to manufacture the wings and install the model aircraft fuel tank inside the wings.

Except for the places where necessary parts such as landing gear are placed, the rest of the space in the two wings has been turned into fuel tanks.

In addition, some unused areas on the model aircraft have been turned into fuel tanks. This model aircraft can hold a total of 475 liters of aviation kerosene, which is about 370 kilograms.

After getting this data, I silently calculated the take-off weight of the fully fueled aircraft model in my mind, and it seemed to be less than 1.6 tons.

For a thrust of 2.8 tons, 1.6 tons is just over half of the data, which means that this aircraft model can also hoist 1.2 tons of other things.

After half a year of hard work, he finally pulled out the mechanical parts of the model aircraft.

And now the time has come to June and July. In these six months, he has not paid any attention to the company's affairs.

He didn't even know what was going on in the outside world and concentrated on building his model aircraft.

It was also during this six months that he secretly and painstakingly dug out the 2.5-meter engine parts.

With the current batch of parts, he can install two 2.5-meter turbojet engines as long as he wants.

But he has always been worried and never dared to get this engine out.

In the workshop, after the last piece of carbon fiber skin of the aircraft model was riveted, only the nose of the aircraft was left unassembled.

This leaves the unassembled nosepiece, which is where the electronics are placed.

As long as the flight control and avionics are installed in the model aircraft, the model aircraft can now fly into the sky and look for the sun.

But all this has not started yet. The next thing he has to tackle is the internal control system.

As for the control system, he had already thought about what he wanted to do before.

And some time ago, he came across a live video of a flight simulation game on Kuaishou.

That simulation game is very realistic, with joysticks, throttles, rudders, etc.

And they are available at various prices, with the lowest price only costing 30,000 RMB.

The most expensive one is available on the market for civilian use, priced at NT$50,000.

This is a flight simulation cockpit. It looks like a gyroscope.

It allows the cockpit to flip at any angle in the air.

He also took a fancy to this thing and planned to use it to build his console.
