Movie black technology

Everyone in the room held their breath and concentrated on the large monitoring screen in front of them.

The screen is the real-time situation of the test bench, and the computer next to it also displays various parameters detected from the propeller.

"Huh~"

At this time, the propellers on the test bench had started slowly, making the sound of warming up and running, which sounded a bit sharp.

"Gulu~"

The people in the room swallowed nervously when they saw the situation, and Chen Shen unconsciously approached the monitoring screen.

Whether this big thruster can be used depends on its performance later.

If it can't be started, it means that although this big thruster has passed the inspection level, it is still a failure.

The production of nano thrusters has a yield rate, and the production of such large thrusters naturally also has a yield rate.

After all, it is made by learning from the self-assembly technology of human biomacromolecules. The mechanism in the human body sometimes makes mistakes by itself. The propeller needs to be equipped with 500,000 nano-propellers, and it is normal for some mistakes to occur.

But once this kind of big thruster can't work, it is tantamount to useless.

There is no hope of returning to the factory for repair, at least no country in the world can repair it with the current technology in the world.

Its only value may be to send it to the rear for detailed analysis and research to see where the problem lies, so as to avoid mistakes in the future.

Everyone understood this truth, so they were extremely nervous in just a few seconds.

Zhang Li, who was in charge of the plasma propulsion technology group, clenched his fists and exhaled heavily. His forehead was sweating, and he had to support the people next to him to stand still.

at this time.

puff!

Finally, there was an almost inaudible sound from the sound system in the room that collected the sound of the test site, and then the nozzles of the propellers installed vertically on the machine seat began to eject blue plasma. The ejected plasma was not like a plasma cannon. The plasma doesn't travel very far in the atmosphere before dissipating, leaving only a short blue trail on the screen.

It looks sci-fi and dreamy.

There were bursts of exhaling sounds from the room almost at the same time, only Zhang Li was still sullen, and then Chen Shen immediately looked at the parameters on the computer screen.

"29.4KN."

In terms of conversion, the thrust generated by the thruster detected on the test bench is equivalent to 3 tons of force.

This is still the full force of the propeller. According to the design index, the theoretical limit of each propeller is at least about 17 tons.

"Keep pushing harder."

Chen Shen said to the controller on the console next to him.

"Received." The controller immediately increased the output of the thrusters.

After a warm-up sound similar to that just now, the plasma ejected from the tail of the thruster increased rapidly, and the tail flame of the thruster also became longer.

However, the atmospheric environment blocks the plasma too much, and the tail flame does not exceed half a meter no matter how long it is. It seems to match the small body of the thruster very well.

The thrust has been increased to 4 tons, and then quickly advanced to 6 tons. Chen Shen and others have been paying attention to the information on the screen. During this period, all the parameters of the thruster are normal.

"Huh, it seems that we have succeeded this time!" Zhang Li finally let go of his worries and found a chair to sit down.

Chen Shen also nodded, "It has been running for almost three minutes now, and it is unlikely that there will be any abnormalities in the future. Continue to increase the thrust and test its extreme performance."

The controller does so.

Afterwards, the exhaust flame at the end of the propeller on the test bench was like taking medicine. It broke through the previous half-meter barrier in two strokes, and then broke the one-meter barrier in less than three seconds.

When the thrust reached the limit, the tail flame of the thruster had reached a length of nearly ten meters, and the plasma ejected at an extremely high speed hit the ground, leaving traces of dots, and then was led into the pool by the diversion groove below.

Chen Shen glanced at the current thrust monitoring, 17.6 tons.

If it was in the daily cruising state before, then the propeller is now at full power.

"Adjust the angle of the propeller."

As soon as Chen Shen finished speaking, the propeller over there was slowly turned over under the control of the machine.

Adjust the angle from vertical to the ground until it is parallel to the ground, and the tail flame no longer hits the ground, but disappears directly into the air as before.

Under the control of the controller, the propeller has been changing back and forth between vertical and parallel angles. It looks like a naughty child is waving a lightsaber on the test bench.

Generally, the time for a test run of a rocket engine is calculated in seconds, usually around 500 seconds, because the rocket engine only works for so long when it is launched.

However, plasma thrusters are different. They have to work for a long time, so the test run time is naturally longer.

According to the original plan, if there is no problem with this test run, it will last for a full ten hours, that is to say, the test run will be completed from noon to midnight.

Only the thrusters that have completed this test can be installed on the Tibetan Antelope.

The initial test went smoothly, and there were no major disturbances afterwards. From noon to evening, the thrusters on the test bench never stopped working, and the thrust output and direction were constantly changing during the test.

In the monitoring room, the tension was relieved, and the mode of taking turns to be on duty began. Everyone was responsible for monitoring in batches, and some of them took a break to eat first.

Chen Shen didn't go back to the monitoring room directly after eating, but walked to the side of the test bench.

It is already dark now, and the main body of the thruster cannot be seen from this angle, but the plasma ejected when the thruster adjusts the angle can be seen.

Apart from the light sound of the propellers, there was only the sound of the evening wind blowing the fallen leaves on the ground.

Compared with rocket engines, plasma thrusters are quiet and safe to test.

If the current test drive is a rocket engine, he can be sent to the hospital with only sound waves at this distance, not to mention the high temperature and thick smoke...

Looking at the swaying propeller not far away, and looking at the progress bar of the project that has reached 99% in the system, Chen Shen silently took out his phone...

Behind him, the two security personnel looked at each other with helpless expressions.

After shooting a one-minute short video contentedly, Chen Shencai went back to the monitoring room to sit in charge, and took a look at the data recorded on the spot.

After waiting until midnight, the propeller shut down smoothly, and the test was a complete success.

The people at the scene celebrated briefly, and went to the meeting room to analyze the parameters of this experiment without sleeping.

After the meeting, it was already morning. Chen Shen looked at the video he took last night on his phone, and uploaded it on the Internet.

Just add fire to the last 1% progress.
