Chapter 302 Take-off and landing test, the powerful performance of the aircraft!

The first step in the flight test of a gravity aircraft is the take-off and landing test.

Takeoff and landing means take-off and landing.

According to the flight test plan, the first step requires the aircraft to slowly rise to a height of 100 meters, and then slowly descend until it relies on the aircraft's octagonal support to land on the ground.

Because it is just a warm-up for the flight test, it can also be understood as an early test and still belongs to the internal testing stage.

The only superior who came was Mr. Zhao, who was the leader of the military's scientific and technological research and development and the direct manager of the project.

When the takeoff and landing test was about to begin, Teacher Zhao rushed over in time. He hurried to the square and immediately asked, "How are the preparations going? Is it about to start?"

"It's about to begin." Zhang Shuo said as he looked at the huge monster in the distance.

Teacher Zhao also looked at the gravity aircraft.

He had looked inside the laboratory before, but he had always gone to the second floor and looked down. This was the first time he had transported it to an open area, and he was also shocked by the huge size of the thing.

The diameter of the annular pipe of the main body of the gravity aircraft is more than 2 meters, which is equivalent to the length of the wings of a B- bomber when they are spread out.

There is still a big gap compared with large passenger aircraft, but the problem is that the main body of the gravity aircraft is a ring-shaped pipe, not a thin wing. The material used is solid, and the overall shape is hemispherical and can give people a great shock.

"With such a big creature, taking off... is there any problem?" Teacher Zhao asked again in shock.

"no problem!"

Meng Zhilin said very confidently, "Teacher Zhao, don't worry, we are all ready, and all the tests have passed."

"I dare to issue a military order! The test will definitely pass successfully!"

Teacher Zhao nodded slightly towards Meng Zhilin, but his solemn expression did not relax, and he still looked at Zhang Shuo.

Zhang Shuo nodded and said, "It should be possible to pass normally..."

"Whoo~~~"

Teacher Zhao let out a sigh of relief, his expression visibly relaxed.

Meng Zhilin stood aside feeling depressed. He even shouted for a military order, but in the end, it was not as good as a word from Zhang Shuo.

In Teacher Zhao's mind, his words were obviously not very convincing.

"Ah~~"

Meng Zhilin was feeling depressed and simply went over to prepare for the testing work.

The take-off and landing tests were still commanded by Meng Zhilin. He was the overall person in charge, so he was allowed to participate in the testing work on the front line.

Among all the personnel involved in the test, others are responsible for monitoring data and reporting the status of the aircraft at any time.

These include gravitational intensity, coverage range, actual gravity values, as well as speed, altitude, power operation, operation of electric motors in various parts, and so on.

The direct operator of the gravity vehicle is Zhang Jianxin, and there are two substitutes, Deng Yan and Liu Jinling.

They are all professional drone operators.

Zhang Jianxin is the first operator. He has more than 2,000 hours of experience in operating large UAVs and remotely operating large aircraft, so he can be said to be experienced.

Even so, Zhang Jianxin still felt tremendous pressure.

This operation mission is completely different from drone operation. He needs to stand dozens of meters away and operate a device connected to the information center.

The operating software on the equipment is modified based on the drone operating software, and the operating methods are similar. However, because the flying methods of gravity aircraft and drones are completely different, and the flight test is extremely important, it still brings a lot of pressure.

Zhang Jianxin sat upright in front of the equipment.

Meng Zhilin stood aside, and various data were constantly reported in his earphones.

After all the data was reported, he connected to Teacher Zhao and reported, "Everything is normal, please give instructions!"

"let's start!"

Following Teacher Zhao's words, Meng Zhilin announced, "Get ready!"

"Ten seconds left..."

"10, 9, 8..."

"3, 2, 1!"

"Connect the gravity system!"

The energy part of the gravity drone, that is, the hydrogen bomb battery, is always in operation.

To take off, electricity is connected to the gravitational system to stimulate the gravitational field and officially start the blades of the large electric motor.

Once the gravitational system is connected to electricity, it will instantly create a huge gravitational field.

The gravitational field strength on the gravity aircraft exceeds 1.1 of the earth's gravity. After the gravitational field is turned on, the aircraft will be subjected to an upward gravitational force. Some devices above the aircraft will not be covered by the gravitational field, which can also balance the force of the aircraft and prevent it from flying directly under the action of gravity.

This is designed to maintain the stability of the aircraft.

But in fact, the aircraft will still slowly rise into the air under the influence of gravity, mainly because the air will generate upward thrust.

The gravitational field acts on the aircraft and also on the air. The surrounding air is driven upward by gravity, which also brings a certain thrust to the aircraft.

If it is under normal conditions, the thrust brought by the air can even be ignored, but the problem is that the gravity aircraft is in a state of no force, so the air thrust must be taken into consideration.

Therefore, the electric motor fan above needs to run slowly to keep the gravity aircraft stable.

Zhang Jianxin’s control is mainly carried out on each electric motor.

When the motor below is controlled to run, the gravity aircraft will accelerate upward under the thrust of the fan, and the speed is very fast. The calculations for the aircraft's takeoff have been made very detailed and accurate, but there will definitely be differences in actual tests.

You need to be very cautious in operation.

Zhang Jianxin kept staring at the screen, feeling excited and nervous.

Even though they have a lot of experience in drone operations, the gravity aircraft is too large. For a big guy weighing more than 100 tons, deceleration is a problem when it goes too fast.

Today's gravity-driven aircraft are much more flexible in upward movement than in lateral movement, because the direction of the gravitational field is upward, and autonomous control is not yet possible. Lateral movement depends entirely on the thrust generated by the motor blades.

When the test officially began, accompanied by a "boom" sound, the aircraft was seen slowly detaching from the bracket and slowly floating upwards.

Then I heard a sharp "creaking" sound, which was the sound of metal collision and friction when it was separated from the bracket.

Finally, there was only a buzzing sound coming from the blades of the gravity craft's motor.

"Moved!"

"It's moving, it's already off the bracket!"

A group of people exclaimed.

Everyone was watching the gravity craft.

The scene of this huge monster slowly rising into the air is very shocking.

Teacher Zhao also exclaimed, "It's up! It's flying!"

He clenched his fists tightly.

The faces of the others were also filled with excitement. They watched the aircraft move upwards little by little. Many of them did not even blink, as if they were afraid that something unexpected would happen if they blinked.

Under the gaze of the crowd, the gravity aircraft slowly moved into the air. The scene of the huge metal body floating on the ground was very shocking, as if seeing an alien spaceship. If it were a different scene, many people would surely pick up their phones to take pictures.

It is not allowed here.

They could only use their eyes to record this unforgettable moment.

"Height: 53 meters..."

"Height: 78 meters..."

"Height: 99 meters..."

The gravity aircraft rose little by little and finally reached a height of 100 meters.

When he heard the report of "one hundred meters", Meng Zhilin shouted decisively, "Stop ascending and prepare to descend!"

He shouted loudly without blinking, and was obviously nervous, afraid that something might happen suddenly.

The same thing happened to the others, and everyone watched the aircraft carefully as it began to fall.

The falling process is almost the same as the rising process, both of which are slow movements, except that there is a "small acceleration" process in the middle to test the aircraft's ability to withstand the fall.

'Small acceleration' has almost no impact, but it is a challenge for everyone's heart.

In the eyes of everyone, the aircraft clearly experienced a moment of weightlessness, but in fact it was not weightlessness. The gravitational field was still on, and the coverage of the field was not adjusted. It was just that the electric motor above was turned on at high power.

Its downward acceleration is ten times smaller than that of free fall, but it is still very obvious on the large size of the gravity aircraft, making people feel their heart tremble.

The accelerated descent only takes a moment, and then the power of the upper motor is immediately reduced, and the gravitational field and the lowering of the motor blades are used to help the aircraft return to stability.

When it descended to a height of 30 meters, the aircraft was almost suspended in the air, and the speed of its downward movement made people feel impatient.

Every meter takes dozens of seconds.

This kind of caution is very necessary because the gravity aircraft is too big. Weighing more than 100 tons, it would be dangerous if it collides with the ground with just a little speed, and the gravitational field cannot reduce the strong momentum brought by the collision.

When it descended to 25 meters, the aircraft's octagonal support opened and it slowly moved closer to the ground.

The 'foot' under the octagonal bracket collided with the ground with a sound, and then the bracket body slowly bent.

Finally, the aircraft landed smoothly.

It was only at this time that everyone breathed a sigh of relief, "Success!"

“Finally landed!”

"When I was accelerating just now, I was too worried, afraid that something might go wrong and I would crash directly..."

"This test was perfect, right? There were no problems. Everything went as planned!"

"Great, it's over..."

Everyone cheered happily.

Meng Zhilin also let out a long sigh, took off his headset and looked at Zhang Jianxin.

Zhang Jianxin stood up, and Deng Yan and Liu Jinling also came over. They stood side by side and saluted. "Report, the test flight operation mission has been completed!"

"very good!"

Meng Zhilin nodded with satisfaction and prepared to use the headset to report to Teacher Zhao.

Teacher Zhao had already walked over. He looked at Zhang Jianxin and the others with appreciation and said, "The task was completed very well!"

"You must be under a lot of pressure. It takes courage to conduct such a test!"

Zhang Jianxin's face was full of determination, but he was obviously still very excited.

The same is true for Deng Yan and Liu Jinling.

They are the backup operators, but it is also remarkable to be a backup operator. With the experience of participating in flight tests, there will be opportunities for operation in the future.

Teacher Zhao affirmed the testing work, and then went into the laboratory with Zhang Shuo and others to discuss the next step of work.

Take-off and landing tests will still be carried out in the future, and some other measures will also be added, such as accelerating during the launch process, increasing lateral movement, etc.

These are all part of the plan and generally there won't be any problems.

The biggest test that the gravity aircraft has to go through is a formal comprehensive flight performance test. At that time, senior teachers will come to watch.

That is the most important test, and everything is a preparation for it.

……

The comprehensive flight performance test is highly valued by senior teachers.

As for the formal test of the research, the main technology of the gravity aircraft can be determined through testing, and gravity aircraft with various functions can be developed based on this.

After the basic flight test was completed, the research team finalized the time for the comprehensive flight performance test, which was scheduled for one month later, and several small tests would be conducted in the middle.

The senior teachers also knew the test time, and many teachers had confirmed their participation. Every teacher attached great importance to the test.

Gravity aircraft are the technological crystallization of the new physics direction, which mainly involves hydrogen bomb batteries and gravity technology.

The two combined will completely change the technological logic of aerospace, and will also enable China to become the overlord in the aerospace field, and it can even be said that there is no competitor.

In the face of gravity aircraft technology, other flying devices can be said to have no competitiveness at all.

For example, military.

The technical advantages of gravity aircraft are too great, because they can be made very large and there is no need to worry about energy issues, so they can be used to create real aerospace motherships.

The huge aerospace mothership can remain suspended in the air and carry a large number of military weapons and facilities.

With large radars, various missiles and weapon systems, and the ability to carry other aircraft, the aerospace carrier will become an invincible warship that can never be shot down.

The advantages of this type of warship are too great. By utilizing its high altitude advantage, ground threats will be destroyed early and ordinary fighter jets will have no chance to get close at all.

The only threat is cruise missiles or long-range missiles, but no matter what type of missile it is, it will be locked and intercepted in advance and will not pose any threat.

The aerospace carrier will definitely be a more deterrent sky fortress than an aircraft carrier on the ocean.

Of course, the aerospace carrier is still a long way off. Even with the basic technology, it will take a long time to manufacture and many technical difficulties must be overcome.

Conventional military gravity vehicles are relatively simpler, requiring only weapons to be carried on the vehicle.

Aircraft fly by getting rid of gravity. The flight itself has nothing to do with the density of the air, so the flight altitude is not restricted.

This is of great strategic significance.

For example, if it reaches an altitude of more than 30,000 meters, it is difficult to be shot down.

Gravity aircraft are not subject to energy restrictions, their combat radius can cover the entire earth, and they can fly directly to the other side of the earth at extremely high altitudes, which directly gives them a powerful deterrent effect.

Theoretically, the aircraft is large and its load capacity is not restricted, so it can carry a large number of advanced weapons, which naturally increases its deterrent power.

and many more.

When thinking about the powerful performance of the gravity aircraft, everyone who knew the news was eager to watch the flight test immediately.

The base is also constantly preparing for comprehensive testing.
