Chapter 150

Subsequently, Wang Bin, Professor Piao and the others, soon came to a special house not far from the test bench in the workshop, which was all made of special glass by Wang Bin and his Tiangong Technology. If anyone looked closely, they would find that, The thickness of each piece of glass in this house built by Tiangong Technology’s special glass reaches 30 millimeters.

It can be seen from this that the defensive power of this room is actually for the safety of the workers in the workshop. After all, this is a test run of an aero engine. Once an accident occurs, it is very fatal.

Let’s not talk about other things, just take the various blades of aeroengines. Because the speed of the engine is very fast when the engine is in trial operation, the centrifugal force generated is also very large. Once the blades fall off, the damage will be caused. It is very scary. Once you encounter people, the result is self-evident, let alone other accidents.

When everyone entered this room, the people in this room also began to close automatically, and at the same time various facilities in the room began to operate automatically, such as exhaust and ventilation systems.

In addition, on the piece of glass facing the front of the test bench, a faint light began to shine, and various lines appeared around the engine, as well as the current state of the engine data and so on.

Yes, the piece of glass facing the engine is not just a piece of transparent glass. In fact, there is a large transparent display in the middle of the glass, a large and ultra-thin transparent display manufactured by Qin’s Industry. Screen.

Of course, the glass of this display is made by Wang Bin and his company’s Tianyuan Optics, and the display technology is Qin’s own technology.

It didn’t take long for the various equipment in the room to be started. At the same time, the various windows in the test workshop, with the help of electric equipment, began to close and covered with a cover.

Finally, the lights in the workshop began to dim, and soon the workshop became very dim. However, due to the dimming of the workshop, the various data and lines on the transparent glass in front of Wang Bin’s room became very dark. It became unusually clear.

“Mr. Wang! Is it possible to start the test drive?” As Wang Bin looked at the data on the front glass, Professor Poke asked Wang Bin.

“Let’s start!” Wang Bin nodded to Professor Poke and said!

After listening to Wang Bin’s words, Professor Poke said to the controller on the side: “Xiao Jia! Start testing!”

“Okay! Poke Professor!” After speaking, the young man named Xiao Jia immediately pressed the button to start the test drive.

Following Xiao Jia’s actions, the engine on the test bench in between began to start slowly.

Of course, because all the professionals present except Wang Bin naturally know that this is not the engine itself rotating, but the power equipment on the test bench is driving the engine to rotate, accelerating the engine to a certain speed. So that the engine ignites.

With the passage of time, the engine speed on the test bench gradually became faster, and at the same time, there was no abnormal data in the detection data of the display screen.

At this moment, several young test drivers who were really observing engine data began to report on the test drive.

“The test run started normally, and the engine turned normally.”

“The engine rotation data is normal!”

“The engine vibration data is normal!”

“…normal!”

“…normal!”

Following the report of the test driver, it was Wang Bin or Professor Poke and the others. Their expressions were very good. Although it is said that it is only the test bench that drives the test, there is no doubt that this is the first step to success. If it fails to pass or there is a problem, then don’t talk about it later. Fortunately, everything is normal now, which makes everyone breathe a sigh of relief.

“Start fuel input to the test target.”

After the report on the test bench was completed, Professor Poke ordered again.

Although the engine test runs, the sound is very loud, under normal circumstances, even if you face to face, you may not be able to hear the other party’s speech.

But it is different in this room. Since this room was built at the beginning, this aspect has been considered. Therefore, although the sound of the engine can be heard in this room, it is not very loud.

“The fuel input is normal!”

“The target is operating normally!”

“The target speed is normal!”

“The target is normal inside!”

Following the report of the engine running situation, soon, Professor Poke finally gave the order to ignite.

“ignition!”

“Understood! Ignite!”

With the order of Professor Poke, the operator of the test bench immediately pressed the ignition switch, and the engine on the test bench immediately heard a low and screaming sound, even if it had been done in this room. It can already be heard in the strictly soundproofed room.

“The target enters the slow turning state! The operation is normal!”

“Twenty percent of the target speed, it is accelerating, and the speed is normal!”

“The target output power is 2%, it is slowly Ascension, the power output is normal”

As the engine speed gradually increased, the output power of the engine soon reached five percent of the theoretical maximum output power and began to maintain at this speed!

In this way, the engine has been stably maintained at a 5% thrust for more than ten minutes. After Professor Poke found that there was no problem, he said again: “Increase the speed and enter the cruising state.”

“Yes!”

“…”

As each item of the test run was completed almost perfectly, the faces of Wang Bin, Professor Poke and others were already full of smiles.

Although the first test run of the engine at this time has not yet ended, no matter what, the test run of the engine can go here, which has proved that the design of this engine has no fatal flaws, at least it is feasible.

Of course, whether the specific performance of the engine can meet the design requirements or not will be known after subsequent test runs and more test runs in the future!

As the test items of the engine are going on, and finally after a series of test runs, this test has reached the final test. If the final test items are normal, then today’s test can be said to be perfect, and at the same time, at the end The test is also a major test for the aero engine on the test bench.

Because the final test is the maximum working state test of the aero engine, that is, the afterburner working state of the aircraft during flight, this working state is a huge test for the state of the various parts of the aero engine, and it can even be said to be a test. The limits of each part of the engine.Of course, in the maximum working state, the combustion temperature inside the engine will continue ascending until it reaches the limit that the engine can withstand. At the same time, the pressure inside the engine will also reach the limit that the blades can withstand. The professor said that the special high-temperature resistant glass of Tiangong Technology could not be used on turbine blades.

Although the special high temperature resistant glass of Tiangong Technology also has a very strong ability to withstand high temperature and high pressure, the high pressure resistance at high temperature is not the professional attribute of this high temperature resistant special glass.

If under normal circumstances, that is, under the cruising state of the engine, it is still feasible to use special high-temperature resistant glass, then their special high-temperature resistant glass is absolutely unbearable under high temperature and high pressure.

As the engine enters the maximum working state, the sound of the engine becomes more and more acute. At the same time, Wang Bin and the others can clearly see the Mach rings on the flames ejected by the engine.

At the same time, on the transparent display in the front, the thrust of the engine was rapidly ascending, and it soon exceeded the maximum thrust on the original drawing, which was a thrust of 120 kN, and finally stopped at 130. The maximum thrust is about nineteen kilonewtons.

However, when Wang Bin and others were a little happy, thinking that the test was about to be successfully completed, suddenly everyone discovered that the thrust data of the engine had a new change, that is, the thrust of the engine had fluctuated greatly.

Seeing this situation, whether it is Wang Bin himself or Professor Poke and others, they are all nervous. Wang Bin and Professor Poke and others all know the bad thing. There must be a problem inside the engine. Otherwise, the thrust of the engine. Certainly this will not happen.

So Professor Poke immediately said decisively and loudly: “Stop now!”

When the controller heard Professor Poke’s words, he didn’t dare to care at all, and immediately pressed the stop button. Just after the controller pressed the stop button, the flame behind the engine disappeared and the sound of the engine began to appear. Changed.

After the controller pressed the stop button, it took a full five or six minutes before the engine stopped completely.

After the engine stopped rotating, there was no sound in the control room for a long time. Even Professor Poke and the others lowered their heads, thinking about what went wrong in this test.

After all, this is the first test run of the first aero engine manufactured by Tiangong Technology, but now it is! Now there was a problem during the first test drive, and the mood of everyone in the control room can be imagined.

Just when everyone was feeling down, Professor Poke raised his head and said to the controller on the side: “The surveillance record of the last maximum power test when we tested just now has been video played again.”

As Professor Poke’s words fell, the screen of the engine’s maximum power test reappeared on the front transparent display, and the engine’s data also appeared on the display. At this time, everyone did not pay attention to the engine. The screen, instead, focused own eyes on the various test data on the display screen.

As time passed, everything in front was very normal. Soon the screen reached about three minutes and sixteen seconds when the maximum output power test was started, which was about ten seconds before the thrust fluctuation occurred.

At this time, Professor Shizha found from the data on the screen that the temperature of the front bearing of the engine turbine had reached a very high level at this time, which was far beyond the normal maximum output power level.

Seeing this poke in Professor’s heart, I have already made a general judgment. This should be a problem with the engine’s bearing or cooling system.
