Starting Off With A Blacksmith Workshop Chapter 127

A turbojet engine with a length of 90 centimeters and a diameter of 29 centimeters was placed on the shelf in front of him at the moment.

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

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

How big is a typical micro engine? The audience is about 25 centimeters long, and the net weight is close to two kilograms.

And how much thrust does the micro-turbojet have? About twelve to fifteen kilograms.

The one in front of him is different. It is 90 centimeters in length and has a total weight of 120 kilograms. What about the thrust? That's 1.4 tons!

With such data, it has already left the ranks of model airplane turbojet engines.

Compared with the micro-turbojet used on model airplanes, this is a huge difference. The thrust of one is still at the kilogram level, while the thrust of the other has stepped into tons!

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

How long is a VW small pineapple? Four meters! The weight is 1060 kg, and a single engine can carry a small pineapple into the sky. One can imagine how powerful this engine is.

His model airplane is 3.5 meters long, and the final total weight will definitely not exceed 1.2 tons. The total thrust of the two models is 2.8, and 1.6 tons of other things can be attached to the plane.

Now that the engine has been built, it is inevitable 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 someone to build a simple one in the Shuzhen factory area, an open space that hadn't been built yet.

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

A vertical weighbridge was set up on the high platform, and how much thrust the engine can produce is shown by the weighbridge!

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 weighing more than 200 kilograms on the small truck with anti-vibration measures, and then they headed towards the location of the test bench.

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

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

Even if the turbojet engine was produced this time, he was not too surprised, on the contrary, he was very fortunate,

Fortunately, what he got was a turbojet engine. There was no market for this thing in the civilian market, so he didn't have to worry about how much it would affect him.

The two came to the open space of the test bench, hoisted the engine onto the test bench by reversing the chain,

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

Only then did he push a barrel of aviation kerosene to the test bench, insert the oil pipe directly into the oil barrel, and manually pump some fuel into the engine.

All the preparatory work has been done here, 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 started to work, the engine made a whistling sound unique to turbojet.

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

The tail flame is also red from the beginning, slowly changes to orange, and finally forms a blue tail flame,

When you see the blue tail flame, you know that the temperature inside the engine has exceeded 2,000 degrees.

During the observation, the engine was running very smoothly. When the fuel was increased to the maximum, I began to look at the data displayed by the weighbridge.

1400KG.

When seeing the displayed data, Li Zhenhua also showed a smile on his face,

And Liu Xiaodong, who was by his side, also followed. Seeing the data above, he didn't understand him, so he searched the Internet to find out what level a thrust of 1.4 tons is.

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

Then I searched for the highest-level Fo-22 fighter jet in the country. The thrust-to-weight ratio of this engine is 10~11.5.

Compared with the 12 in front of him, the thrust-to-weight ratio is actually stronger than that of the F119, which made him feel horrified.

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

After learning something, Liu Xiaodong leaned towards Li Zhenhua.

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

Years ago, on the list you gave me, it was a stove and a photolithography machine. You played too much!

As far as the engine in front of me is concerned, I know it is not simple, I just searched 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 Fo-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 general guess.

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 injection of fuel and slowly stopped the engine.

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

Everyone saw the weird high platform more than two meters high, and they all saw the cylindrical things 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 yellow earth next to Liu Xiaodong, motioning him to sit down.

After he sat down, he opened his mouth and said: "I didn't plan to do anything, but when I went to the Maple Leaf Air Show last time, I came into contact with Buddha 14,

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

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

Wouldn't that be able to realize my idea of ​​flying a plane? That's what I thought, purely for fun, nothing else! "

After Liu Xiaodong heard it, he didn't fully believe it. The engine is so awesome, could it be purely for fun?

But he couldn't do anything about it, who would let him be the boss!

During their rest period, the engine also completely cooled down,

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

Returning to the manufacturing workshop, he took the trouble to disassemble the engine,

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

After a pass inspection, all parts were within his expectation and performed very well.

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

Now he can start working on the second engine, which will be built faster than the first,

Some of these parts have been machined before, which also speeds up the speed.

After finishing the two engines, the next step is to make the variable-sweep wing receiver of the model aircraft.

The design of this receiver is completely copied from the Buddha 14 structure, of course, some things have been changed.

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

I believe that the CIA in the country will definitely find ways to get rid of him or get him to the country.

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

Since he discovered the benefits of single crystal alloys, he smelted materials that can be made into single crystals, so he is not afraid of the high cost!

The receiver of the model airplane was manufactured by him day and night, and all the parts were produced by him.

After the casing is done, it is the manufacture of the wings, and the installation of the aircraft model fuel tank inside the wings,

In the middle of the two wings, there is a place to prevent necessary parts such as landing gear, and the rest of the space is used as a fuel tank.

In addition, some idle and useless places on the model airplane have also been turned into fuel tanks. The model airplane can hold 475 liters of aviation kerosene in total, which is about 370 kilograms.

After getting this data, I silently calculated the take-off weight of the model airplane 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, that is to say, this aircraft model can also hoist 1.2 tons of other things.

After half a year of hard work, the mechanical part of the airplane model was finally pulled out by his hands.

And now the time has come to June and July. During the six months, he didn't care about the company's affairs at all.

He doesn't even know what's going on in the outside world, and concentrates on building his model aircraft.

It was also during the past six months that he sneaked out and rubbed out the 2.5-meter-sized engine parts after untold hardships.

With the current batch of parts, as long as he wants to, he can assemble 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 the last piece of carbon fiber skin of the aircraft model was riveted with rivets, only the nose of the aircraft remained unassembled.

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

As long as the flight control and avionics in the model airplane are installed, UU Reading www.uukanshu.com can now let the model airplane fly into the sky and find the sun side by side.

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

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

And some time ago, he got a live video of a flight simulation game on Kuaijiu,

The simulation game is very real, there are all kinds of joysticks, throttles, rudders, etc.

And there are all kinds of prices, the lowest price only needs 30,000 RMB,

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

This is a flight simulation cockpit, which looks like a gyroscope in appearance.

The inside of the cockpit can be flipped at any angle in the air.

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