Super Weapon Swap System

What should an engine look like after 150 hours of experiment?

In the test run, there will be all kinds of faults. For example, if an oil pipe breaks, the lubricating oil will be everywhere, but now the engine is clean.

Did you clean it?

Hearing this, the person in charge suddenly thought of something, his face showed a trace of panic, and later calmed down: "yes, we heard that our superiors were coming to visit, so we cleaned the engine."

It's all to welcome the superior and show our clean and tidy work style. How about it, can't it?

"Then you're really clean. You're not only cleaning the shell as new, but also cleaning the inside."

With that, Qin Guan put on his new white gloves, then put his hand in the tail nozzle, touched the turbine blade inside, and then took out his hand. Then, he raised his arm and stretched out his fingers to let everyone have a clear look.

I didn't even touch a dust!

How is this possible?

You know, even if it is cleaned, after 150 hours of test run, the temperature on the turbine blade is more than 1000 degrees. In this case, the turbine blade can still shine with metal luster and look like a new one?

You put a nail in the stove and burn it red, and then take it out, it will change. After 150 hours of combustion, there must be traces of combustion on the surface of the turbine blade. Now Qin Guan uses white gloves, there is not even a dust on it, let alone the black product after combustion.

Even if the aviation fuel of this era is pure, it is impossible not to smoke black smoke, right?

Seeing here, the air force officers present have understood something.

If you say that the engine has been tested for 150 hours, that ghost will believe it!

"Lao Gu, what's going on?" General Zhang's face turned black. Where did the engine burn? Can it go through a 150 hour long test run? Is this a fool?

President Gu's face was also very ugly: "you fools, are you wrong? This engine is a new engine we intend to equip Xinjian and produce from the factory. Where is the one we test? Take out the one we test!"

President Gu is already in a state of anxiety.

Who had a bad idea? Put this brand-new engine in front of everyone and think it can make a good impression?

Look for our test machine!

"Yes, yes, it's my fault. I've been on the test bench every day for a long time. I've shocked my head." the person in charge said.

"Where is the test driver?" General Zhang asked.

"Yes, yes..." the person in charge was incoherent. In this way, it seems that there is a problem.

"Hum." it must be on the test bench.

General Zhang has been here several times. Of course, he knows where the test bench is. Without the person in charge, general Zhang has gone out.

For engine test run, it needs to be on the test bench. This thing can't be in the room. Otherwise, huge noise can't be transmitted, and it's not easy to control in case of an accident.

For example, in the engine experiment, the blades of tens of thousands of revolutions may break, break for a period of time, and fly out. It is definitely a sharp knife that can cut everything. If it is in the laboratory, it will cause great damage.

Therefore, the test bench is built outside the open space, and it should be lifted in the air.

Outside the factory, on the test bench, the engine has been put on the ground. Several operators are scrambling to screw the nuts on the shell. In the experiment a few days ago, the blades of the primary compressor broke again. They want to assemble the new engine. Therefore, the blades here have not been replaced.

However, the new engine in the factory was recognized as a problem. They had to replace the broken blade quickly.

The shell hasn't been opened yet. A large group of people have come.

The engine is greasy, and the tail nozzle is smoked black. This engine is what it looks like to have been tested, but what are these people doing?

General Zhang strode over and looked at the front blades. Several of them had been broken. The location of the fracture was quite clear. It must have been broken recently.

Even the blades of the compressor can be broken. In this way, can it be said that it has passed the 150 hour test run?

Generally speaking, this 150 hour endurance test run means that the engine can run continuously for 150 hours without stopping. Even if you cheat and temporarily stop for a few hours due to overheating in the middle, that's OK.

However, in the test, the failure of compressor blade fracture also occurred, which means that the engine does not have the conditions for continuous operation at all. If it is broken when installed on the aircraft, the rear fuselage will be interrupted, and the pilot will definitely die!

That's it. Do you have to match the Raptors?

General Zhang's face was very black.

"The engine has been running for more than 150 hours, and the blades have withstood strict tests, and finally broke due to metal fatigue." at this time, the person in charge quickly introduced.

Qin Guan frowned, and his face was not good-looking.

Yes, as I expected.

Turbofan VI is a dystocia project. The scientific and technological personnel of the Han country have great hopes for it. However, there is a saying that the greater the hope, the greater the disappointment.

Because the project indicators are set high.

Think about it. At present, even the F100 engine made by the eagle people is still in trouble. Can the Han country's own scientific research ability be compared with the eagle people?

If the project index is too high and exceeds the scientific and technological level, various faults will inevitably occur.

This was also Qin Guan's initial concern. For the engine, what was needed was reliability.

Now, things are getting worse.

Qin Guan can understand the mood of scientific and technological personnel. Turbofan VI is like their children. They absolutely don't want to see problems in this project or even miscarriage.

They want to keep the project and keep it going.

The original intention was good, but I was afraid of going to hospital in an emergency. Finally, I began to engage in this kind of heresy.

Even if it can run continuously for 150 hours, there can be no such major accident of compressor blade fracture, which shows that there is a problem in the design.

Qin Guan said, "this one has been running for 150 hours. It seems that it can't be used for the time being. Well, isn't there a brand-new one in the workshop? Put it up and let everyone see if it can run for three hours."

Qin Guan's proposal is very simple. It doesn't matter if this one is broken. Take out the new one and put it up. Let's have a look.

"Mr. Qin, you don't know. The engine has just been built and needs various tests before it can be put on the stage. It won't work without ten days and a half months." the person in charge is still delaying.

Of course, it can't be dragged out. It's really dragged out. It's on the stage. Needless to say, it's been three hours. There should be a fault in less than half an hour. Thank God for running for half an hour.

Yes, the reliability of this engine is still very poor, and there are still many problems. Now if these are exposed, the consequences will be very serious.

"Really?" Qin Guan said, "after leaving the factory, this kind of engine will be sent to the army as a spare engine. It will take ten days and a half months to change the engine under field conditions."

"Let's go and see Spey. When we get off the production line, we can turn it with oil. It won't take half an hour," Qin Guan continued.

"When we develop the engine, the performance indicators should be put aside. At least, it should run stably, which is related to the life safety of pilots."
