Chaoshen Technology Trading Mall Chapter 149

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 here 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 aero-engines. 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 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, the glass facing the front of the test bench also began to emit a trace of light, and various lines appeared around the engine, as well as the current state of the engine, 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 ultrthin transparent display manufactured by Qin's Industry. Screen.

　　 Of course, the glass of this display is made by Wang Bin and his Tianyuan Optics, which is a subsidiary of Tiangong Technology, and the display technology is Qin's own technology.

　　 It didn't take long for all the 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 a 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!

　　 Hearing what Wang Bin said, Professor Poke said to the controller on the side: "Xiao Jia! Start test drive!"

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

　　 Following Xiao Jia's movements, the engine on the test bench started 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 on 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!"

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 relieved.

　　 "Start fuel input to the test target."

　　 Just after reporting on the test bench, Professor Poke ordered again.

　　 Although it is very loud when talking about the engine test, under normal circumstances, it is not always possible to hear the other party's speech even if it is face to face.

　　 But it's different in this room. Since this room was built at the beginning, this issue has been considered, so in this room, although the sound of the engine can be heard, 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!"

　　 With a loud report on the engine's operation, soon, Professor Poke finally gave the order to ignite.

　　 "Ignite!"

　　 "Understand! 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!"

　　 "20% of the target speed, accelerating, the speed is normal!"

　　 "The target output power is 2%, which is slowly increasing, and the power output is normal"

　　 As the engine speed gradually increased, the output power of the engine soon reached 5% of the theoretical maximum output power and began to maintain at this speed!

　　 In this way, this engine has been stably maintained at 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 cruise state."

"Yes!"

　　 With the progress of the test drive, each item passed almost perfectly. At this time, the faces of Wang Bin, Professor Poke and others were already full of smiles.

　　 Although it is said that the first test run of the engine at this time has not 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 depends on subsequent test runs and more test runs in the future to know!

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 the various parts of the engine.

Of course, in the maximum working state, the combustion temperature inside the engine will continue to rise 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 it is said that the special high temperature resistant glass of Tiangong Technology also has very strong high temperature and high pressure resistance, 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 absolutely cannot withstand high temperatures and pressures.

　　As the engine enters its 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 also rising rapidly, and soon exceeded the maximum thrust on the original drawing, which was a thrust of 120 kilonewtons, 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 engine thrust data had a new change, that is, the engine thrust appeared to fluctuate 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 the professor poke immediately and decisively said 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 others lowered their heads~www.mtlnovel.com~ wondering where this test appeared. problem.

　　 After all, this is the first test run of the first aero engine manufactured by Tiangong Technology, but now! 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: "Replay the video of the surveillance record of the last maximum power test when we tested just now."

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. Instead, focus on the various test data on the display screen.

　　 Time passed by one minute and one second, everything in front was very normal, and soon the screen reached about three minutes and sixteen seconds when the maximum output power test was started, that is, the first ten seconds or so of thrust fluctuations.

　　 At this time, Professor Time Stamp found from the data on the screen that the temperature of the front bearing of the engine turbine has reached a very high level at this time, far exceeding the level of the normal maximum output power.

　　 Seeing the professor's heart here, he has made a rough judgment. This should be a problem with the engine's bearing or cooling system.
