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

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

However, compared to the miniature turbojet used in the model airplane, the size of this engine is much larger.

How big is a typical micro engine? It's about 25 centimeters, and the net weight is nearly two kilograms.

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

The one in front of him is different, it is 90 centimeters long, and the total weight has reached 120 kilograms, and what about the thrust? That's 1.4 tons!

With such data, it has been out of the ranks of model aircraft turbojet engines.

Compared with the miniature vortex jet used on the model aircraft, this is the difference between cloud and mud, the thrust of one is still kilograms, and the other has entered the ton!

The two engines he built produced a thrust of 2.8 tons, and the aircraft he designed was 3.5 meters long.

How long is a VW pineapple? Four meters! With a weight of 1060 kilograms, a single engine can carry a small pineapple to the sky, so you can imagine how powerful this engine is.

His model aircraft is 3.5 meters, and the final total weight will definitely not exceed 1.2 tons, with a total thrust of 2.8 for the two aircraft, and 1.6 tons of other things can be attached to the aircraft.

Now that the engine has been built, it will inevitably have to go to the ignition test. Although it has been tested in the laboratory, it still needs to be tested in reality.

He didn't have a test bench, so he asked people to build a simple one in the summer town factory, on a vacant land that had not yet been built.

Eight meters of piles were driven to the ground, and the highest grade of concrete on the ground made a two-meter high platform.

A vertical weighbridge was made on the high platform, and how much thrust the engine could produce was shown by this weighbridge!

This is Li Zhenhua's own self-built simple test bench.

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

The two of them reasonably loaded the more than 200 pounds of engine into a small truck with anti-shock measures, and then the two of them moved towards the location of the test bench.

When Liu Xiaodong saw this cylindrical engine, he accepted it very calmly, because he was no longer surprised.

Since the three of them came back from the Military Museum, Li Zhenhua in his eyes has been working hard towards the aircraft engine, the first time he made a star engine, and then he made a white tiger motorcycle.

Even if it was a turbojet engine this time, he was not too surprised, but he was very happy.

Fortunately, it was a turbojet engine, which had no market in the civilian market at all, so he didn't have to worry about how much of an impact it would have on him.

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

After the iron chain connecting the weighbridge and the engine are secured, and all preparations are made,

Only then did a barrel of aviation kerosene be pushed to the side of the test bench, and the oil pipeline was directly inserted into the oil drum, and some oil was manually pumped into the engine.

At this point, all the preparations are done, and the rest is the ignition test.

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

As the engine was put into operation, the engine emitted a screech sound unique to a turbojet.

And with the increase of fuel injection, the tail flame of the engine's tail nozzle is also lengthening!

The tail flame also changed from red at the beginning, 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 2,000 degrees at this moment.

In the observation, the engine runs very smoothly, and when the oil is increased to the maximum, it is only after the data displayed by the weighbridge that it begins to see.

1400kg。

When he saw this display data, Li Zhenhua's face also showed a smile,

And Liu Xiaodong, who was following him, also followed, saw the data above, didn't understand him, and searched on the Internet for what level of 1.4 tons of thrust was.

After such a search, he also knew what the thrust-to-weight ratio was, and when he thought of the engine weight he got before, he calculated that the thrust-to-weight ratio reached 12!

I went to search for the highest level of the Buddha 22 fighter in the mold country, and the thrust-to-weight ratio of this engine is 10~11.5.

Compared with the 12 in front of him, it is actually stronger than the thrust-to-weight ratio of the F119, which makes him feel terrified.

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

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

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

A few years ago, on the list you gave me, there was a furnace and a lithography machine, and you played too big!

As far as the engine in front of me is concerned, I know that it is not simple, I just searched for it,

The thrust-to-weight ratio of this thing has reached 12, which is 12, which is higher than the thrust-to-weight ratio of the engine of the Buddha 22.

What exactly are you going to do? ”

Liu Xiaodong's question, in the screaming sound of the engine, did not make him very clear, but looking at the expression on the other side, he could guess a rough idea.

did not choose to answer him immediately, but calculated the fuel consumption,

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

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

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

Li Zhenhua came to Liu Xiaodong's side, and didn't care whether the ground was dirty or not, and sat down directly.

patted the loess next to Liu Xiaodong and motioned for him to sit down.

waited until he sat down before he spoke: "I didn't plan to do anything, but the last time I went to the Maple Leaf Air Show, I came into contact with Buddha 14,

And sat in the cockpit of the Buddha 14, as for driving it, it was a luxury,

When I come back, I want to get a model airplane to play with, and then I will install a 360-degree lens on the model airplane and make a good console on the ground.

Wouldn't that make my idea of flying a plane come true? That's what I thought, just for the sake of playing, and I don't have anything else in mind! ”

After Liu Xiaodong heard it, he didn't fully believe it, the engine is so awesome, can it be a simple play?

But he didn't have anything to do, who made the family the boss!

During the time they were resting, the engine also completely cooled down.

After the temperature was not so high, Heli removed the engine from the test bench.

Back in the manufacturing workshop, he didn't bother to dismantle the engine.

Check the individual parts inside the starter one by one to see if there is any problem with these parts.

After a check, all parts were within his expectations and performed very well.

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

Now he can start making the second engine, and the second engine will be made a little faster than the first.

Some of these parts have already been machined before, which also speeds things up.

After the two engines were finished, the next step was to make the variable swept wing receiver for the model airplane.

This casing is completely copied from the structure of the Buddha 14 in terms of design, 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 that of Buddha 14,

I believe that the CIA of the mold country will definitely find a way to get rid of him or get him to the mold country.

Lightweight, high-strength alloys are used for the casing parts, and they are also single-crystal metal alloys with particularly stable structures.

Since discovering the benefits of single crystal alloys, the materials he smelted can be made into single crystals, and he is not afraid of high costs anyway!

The casing of the model aircraft was also manufactured by him day and night, and various parts were made out by him.

After the receiver is ready, it is the manufacture of the wing, and the placement of the model airplane fuel tank inside the wing.

The two wings were passed to prevent the necessary parts such as the landing gear, and the rest of the space was turned into fuel tanks.

And some idle and useless places on the model aircraft have also been turned into fuel tanks, which can hold a total of 475 liters of aviation kerosene, that is, about 370 kilograms.

After getting this data, I silently calculated in my heart the take-off weight of the model aircraft with full fuel, which was 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 model aircraft can also lift 1.2 tons of other things.

After half a year of hard work, the mechanical part of the model airplane was finally taken out by him by hand.

And at this moment, the time has also come to June and July, and in the past half a year, he has not taken care of the company's affairs at all.

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

It was also in this half a year that he secretly rubbed out the 2.5-meter-sized engine parts after a lot of hard work.

Now the batch of parts, as long as he wants, can be equipped with two 2.5-meter turbojet engines.

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

In the workshop, after riveting the last piece of carbon fiber skin of the model aircraft with rivets, only the nose position of the aircraft was left unassembled.

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

As long as the flight controller and avionics in the model aircraft are installed, you can now let the model aircraft fly into the sky and find the sun shoulder to shoulder.

But this is not the beginning yet, and the next thing he needs to tackle is the internal control system.

For the control system, he had already thought about what to do before.

And some time ago, he swiped the video of the live flight simulation game on the fast shake,

The simulation game is very realistic, what joysticks, throttles, rudders, etc.,

And there are all kinds of prices, and the lowest price is only 30,000 RMB.

The highest price, the civilian one can be bought on the market, the price is 50,000 yuan,

This is a flight simulation cockpit, which looks about the same as a gyroscope from the outside.

It can be flipped in the cockpit at any angle in the air.

That's what he likes, and he's going to use it to build his console.
