Research starts with PhD students

Chapter 303 Everyone is paying attention, the comprehensive performance test is completed!

The day before the comprehensive performance test, the senior teacher group arrived at the research base in advance.

The teacher group is very large. There are more than a dozen teachers who can be called upon, and together with the others, there are nearly eighty people in total.

Security has been strengthened around the research base.

The nearby land and air armed forces were arranged to conduct training inspections.

In addition to the team led by the teachers, experts and teams from the Aviation Industry Corporation of China, the Space Administration, and the Navy were also sent. They also came to watch the test after hearing the news.

The arrival of so many people made the base inside and outside very lively, but also brought considerable pressure.

Normally, there wouldn't be so many people coming for flight tests.

The more important the research is, the fewer people will come. This is mainly because they are afraid of problems and also consider the principle of confidentiality.

The situation is different for gravity vehicles.

The gravity aircraft is a combination of new technologies and the essence of new physics technologies. Its technological strategic significance is extraordinary and has a significant impact on national strategy and the international dominance of science and technology.

Furthermore, it is also related to national development, military deterrence, and so on.

Its importance is far greater than gold manufacturing technology.

Teachers from all departments are very caring.

In addition, gravity aircraft also involve issues such as the future development of aerospace and the direction of scientific and technological research and development, so the aerospace, aviation and other departments are asked to send representatives to participate.

The determination of the direction of scientific and technological research and development will also cause some original technologies to be eliminated.

After observing the test of the gravity vehicle, the aerospace, aviation and other departments can clarify the technical direction and make some important turning point decisions.

For example, in the aerospace field, some original research and development projects can be suspended, which can also save a lot of unnecessary expenses.

For example, the aviation field, including military aircraft research and development, air force development, and even civilian carrier aircraft research and development, can all be evaluated and analyzed in a new way. Especially for air force development, it is necessary to build a huge air force force system based on gravity aircraft technology.

With so many people coming to the base, it brought considerable pressure to the test preparations.

The day before the comprehensive performance test, most of the work had been completed, but there were still a few impending tests still in progress.

These tasks often continue until the end of comprehensive performance testing.

Some research-related personnel are still at their jobs, but the working environment has changed. They used to record and report quietly, but now there are a lot of people watching.

Including teachers who came here, as well as personnel from aerospace, military and other fields.

While they observe the work, they also ask for specific information about the tests so they can understand the work involved in the related technologies.

Zhang Shuo also became very busy. On the day before the test, he was often very free and had only to wait for the test to begin.

Now he has no time to rest, as he has to take the teacher team to visit the base and the laboratory, and also introduce the gravity aircraft and his original work, etc.

"We have conducted seven take-off and landing tests, and the main difficulty is landing."

"The total weight of the gravity vehicle exceeds 130 tons. Falling to the ground will bring a great impact force. The design of eight support brackets cannot fully guarantee effective support."

"During the third test, one of the brackets broke, but fortunately it was replaced without any major problems."

"We are also considering new solutions for the landing of aircraft. For example, covering the landing site with thick and fine sand can effectively reduce the impact force."

"For example, building a fixed landing point, but the principle is the same. It is also to place materials that can reduce the impact force at the point so that the aircraft can land stably. But the premise is that the bottom of the aircraft must be solidified in shape so that the overall force can be achieved..."

"The benefit of this is that the aircraft no longer needs to have its landing gear open."

After introducing the take-off and landing test work, Zhang Shuo talked about the comprehensive performance test. "Tomorrow's test mainly includes rapid take-off, fixed flight, lateral acceleration, rapid turning and other parts. However, due to the influence of the shape, the acceleration of the aircraft is still limited."

"However, comprehensive performance testing can still provide a lot of basic data and clarify the stability of the technology..."

"This has great reference value for the design and manufacture of future aircraft."

The teachers were all looking forward to hearing this.

The huge aircraft in the square brought great shock to people. After just one look at it, they all looked forward to the testing work.

……

The next morning, the comprehensive flight performance test officially began.

Zhang Shuo still stayed with the teachers. They circled around the gravity aircraft and then entered the control room.

A teacher stood up to affirm the R&D work, and then encouraged all the people involved in the testing work.

Finally, a group of people arrived at the operating table.

Zhang Jianxin, Deng Yan and Liu Jinling sat in a row, with their hands behind their backs and their backs straight. They didn't even glance at the arrival of the teachers.

A teacher asked Meng Zhilin and then called out the names of the three people.

"To!"

The three of them shouted in response and stood up to salute.

A teacher stepped forward and said seriously, "Your work today is very important, very important, very important... Do you have confidence?"

"Have confidence!"

The three of them shouted together in determination.

"very good!"

The teacher put away the seriousness on his face and smiled, "Don't be so nervous, relax, even if the task is difficult, we all believe that you can complete it."

Other teachers followed suit, saying, “Keep working on it, boy!”

"Operating this big thing is definitely a delicate job, it's amazing!"

"It'll be fine today. It looks like the three of them are going to do something big!"

The latter part was said with some joking tone.

Zhang Jianxin and the other two maintained a saluting posture, but the expressions on their faces were almost uncontrollable.

Zhang Shuo also walked over and said, "Don't feel pressured."

"I participated in the entire process of developing and manufacturing the gravity aircraft, including the main core technologies and some points that are prone to problems. All the problems have been solved."

"Even if there is high acceleration or deceleration, or strong winds or rain, it will not affect the operation of the aircraft."

"All you need to do is make sure the aircraft doesn't hit the ground, and of course, doesn't collide with other objects."

"If you accidentally hit a bird or something else during flight, don't panic, just slow down normally. In short, as long as you don't fall under normal circumstances, there will be no problem..."

Today's aircraft are still very imperfect. Some lines are directly exposed on the surface, and some equipment above the aircraft is also completely exposed. Without the obstruction of an outer shell, there are certain safety risks.

The biggest safety hazard is the possible appearance of birds in the sky.

Having said that, there will be no birds encountered during the actual test, because birds have been driven away before the test, and there are teams patrolling all the time, so all possible threats will be eliminated in advance.

The teachers' encouragement was just encouragement. Zhang Shuo's few words made Zhang Jianxin and the other two feel a lot more relaxed.

The interior of the aircraft is very strong and is not afraid of high acceleration or deceleration. As long as there is no major collision, there will be no problem.

There is no need to worry too much about this.

As time passed, the preparations were completed.

The teacher team also arrived at the high platform two kilometers away, which was built specifically for watching the test. The left side of the high platform is directly connected to the air-raid shelter passage, so if there is an accident, you can go directly into the air-raid shelter.

The view from the platform is also very good, and you can see the entire picture of the gravity aircraft.

Amidst the attention of many people, Meng Zhilin received the signal and issued the 'take-off' command.

"Countdown..."

"10, 9, 8..."

"2, 1!"

"start!"

Zhang Jianxin held the pull rod with his right hand and pushed downward, and a green logo connecting to the gravity device appeared on the left side of the screen.

At the same time, the various power units installed on the aircraft are also displayed.

Each power unit initially runs at the lowest speed. Even after the aircraft takes off, no power unit will be shut down but will remain in operation.

The control of Zhang Jianxin and others is mainly aimed at the power of the power unit.

For example, if the power of the electric motor below is increased, the aircraft will accelerate and take off.

For example, increasing the power of the left motor can accelerate the aircraft laterally to the right.

Currently, aircraft do not have the function of autonomous adjustment, which means that they will not rotate in the air, nor can they take off while rotating. This is mainly due to the limitations of their appearance. Otherwise, the process of taking off would be more flexible.

Many people are not aware of this problem, and the comprehensive performance test itself has already brought a great shock to people.

Unlike the last takeoff and landing test, the aircraft did not rise slowly after separating from the bracket, but suddenly accelerated and soon reached an altitude of 100 meters.

A hundred meters may not sound low, but because the aircraft is so huge, it feels as if it has just taken off.

After rising to 100 meters, the aircraft simultaneously turned on the electric motors at the bottom and sides. Driven by two opposing fan blades, the aircraft quickly and obliquely penetrated the sky.

"Speed ​​up!"

"It no longer took off vertically, but rushed over at an angle like an airplane..."

"The acceleration seems to be very fast. It feels like it has become smaller in the blink of an eye..."

"It's still rising. How high is it?"

"Seven hundred meters!"

"It's still rising. Is it going to reach the clouds?"

As the group discussed, the aircraft slowly turned into a small black dot, but it did not completely disappear from the ground's sight.

When it reached below the clouds, the aircraft was controlled to stop rising and instead accelerated its flight sideways, making a large circle around the research base before accelerating down towards the square.

"It seems to have fallen..."

“It feels almost like a plane landing!”

"This is different!"

"The plane has to land like that. This big guy uses gravity technology. It's better to take off and land vertically to be safe."

"The sideways accelerated descent is also part of the test, right?"

Amidst the numerous exclamations, Zhang Jianxin, who was sitting in front of the operating table, had a serious expression on his face. He strictly followed the procedures and knew that he had entered the final stage, which was also the most prone to problems and the most dangerous stage.

Accelerate falling at an angle!
A gravity aircraft is not an airplane, and due to the limitations of its shape, oblique acceleration will have a certain impact. The air resistance alone is already a considerable problem.

Although the speed is not very fast, the resistance encountered by the gravity aircraft is very large.

The resistance in the head-on direction is better, but the resistance in the oblique direction may affect the path of the gravity aircraft.

He had to control the aircraft to slow down continuously, and also make sure that the aircraft's lateral speed reached zero so that it would almost reach the planned landing site.

The requirements for operational control are very high.

Of course, there won’t be any big problems if the operation is not done properly, but with so many teachers watching and so many important people present, the base still hopes to conduct a perfect test.

Zhang Jianxin is under a lot of pressure.

Deng Yan and Liu Jinling continuously reported real-time data to assist in the operation of the aircraft.

The aircraft gradually slowed down and arrived at the designated landing position. It could be noticed that the veins on Zhang Jianxin's left hand were bulging, and it was obvious that he was exerting a lot of force. His left hand controlled the movement of the pull rod little by little, and at the last moment it returned to the starting position of zero.

"103, 99..."

"Height, 213."

Deng Yan excitedly reported the coordinates of the aircraft.

“The deviation is within the normal range.”

"Whoo~~~"

Zhang Jianxin let out a light breath, his forehead was already soaked with sweat. He glanced at the screen, then looked down at the position of the pull rod.

Everything is fine!
Liu Jinling's face was also filled with joy, and he immediately said, "We can prepare to land now."

The aircraft was already above the designated landing position and was slowly descending at a speed of about three meters per second.

The people on the platform also breathed a sigh of relief and started talking excitedly, "Is this going to be okay?"

"It seems there are still 200 meters to go. There shouldn't be any problem with normal landing!"

"This new type of aircraft is safest when it's vertically up and down. I see there are a lot of equipment on it, even the radar is exposed. It's too dangerous to move it sideways."

Several teachers also asked Zhang Shuo, "Is it almost done?"

"Is this where we are? Can we just land?"

"Okay."

"That's good, that's good. I was too worried just now."

"Yeah, it looks a bit fast, but it's really scary."

"It's still not perfect. It's not a formal aircraft, just a test of technology. A lot of equipment is exposed, but it can still fly so fast. It's amazing."

"In the future, we will build a perfect gravity aircraft, preferably for military use, with weapons attached. Then, it will be interesting to test its performance."

“You think this is a performance?”

"Haha~~~"

Amidst the numerous discussions, the aircraft slowly descended to the ground.

When the octagonal bracket actually touched the ground, Meng Zhilin's report was heard, and the comprehensive performance test was completed! "

"The aircraft has returned to the ground safely, please give instructions!"

The senior teacher immediately gave the order, "Finish the work!"

"Wait here!"

After giving the order, the senior teacher walked down from the platform first, followed by the others.
