The Jingwei helicopter was slow on the ground, and it took five minutes to slide out of the test flight field from the workshop.

After all, this is a 130-ton behemoth.

After completing the trial production of the whole machine, the Jingwei helicopter looks huge, just like Chen Shen said before, it is simply a flying train.

Chen Shen and Hang Yucheng watched the helicopter in the test site from a distance in the general control room, while other staff members watched from a distance at the edge of the test flight site, and the fire department and medical team were on standby at the scene.

Waiting for the helicopter to arrive at the predetermined location, Chen Shen heard the voice of test pilot Hu Yuankai from the earphones:

"Tower, the designated location has been reached, please instruct."

"Execute according to the scheduled plan, let's first conduct a preliminary take-off performance test and a hovering performance test." Chen Shen replied on the radio.

"Roger." The other side replied briefly, and then the operation began.

Immediately afterwards, Chen Shen and Hang Yucheng saw the front and rear rotors of the Jingwei helicopter in the center of the test site slowly rotating.

At the same time, there was also a loud noise, and even if the main control room where Chen Shen was located was well soundproofed, the loud sound could be heard clearly.

The sound of a Jingwei helicopter starting is similar to the sound of a jet continuously flying over itself at the speed of sound, with the click of its rotors spinning, more like being around a chainsaw on a construction site......

Even Chen Shen had such a bad feeling when he stayed in the general control room, not to mention the people who were on the edge of the test flight site.

These staff members immediately covered their ears, or took out the noise-canceling earmuffs that had been distributed before to plug their ears.

"It's too loud." Hang Yucheng covered his heart and slightly adjusted to the harsh rotor sound like a chainsaw, which simply added an irritating buff to everyone who heard it.

Chen Shen smiled, "After all, this is just a civilian helicopter, as long as it can be used." ”

That's right, this helicopter was originally designed to transport mechs, and the main use scenario is on the sea, no matter how loud it is, it would be better if you could rely on this sound to make the monster irritable.

Although the people outside felt that the sound was harsh, the test pilots in the cockpit continued to operate the aircraft because of the better sound insulation protection and the noise reduction earmuffs.

After a while, people saw that the helicopter's rotors were getting faster and faster, and soon clouds of dust were rolled up around the helicopter, flying around the helicopter, looking like a small tornado.

At this time, the sound that came out also became a more regular whirring, although the volume did not decrease, but it sounded much more comfortable.

With the roar of the engines and rotors, the huge helicopter was soon lifted into the air with the help of two sets of rotors.

Helicopter take-off is generally divided into vertical take-off and taxi-run take-off.

Vertical take-off is common on TV, the helicopter starts on the spot, and after pulling the altitude, it tilts forward or left and right, changes the flight trajectory and climbs to accelerate.

After the helicopter grows to a certain speed, due to the decrease in the power required by the rotor, there is enough power to increase the pulling force of the rotor and overcome gravity.

It's just that for Jingwei's helicopter, it doesn't need to take off, because its sliding speed is too slow, after all, it weighs 100 tons, and it is not a big truck, how can it be fast.

The huge Jingwei helicopter slowly rose to ten meters in the air, and then entered a state of suspense for a short time, test pilot Hu Yuankai looked at the parameters on the instrument, and the body did not shake violently, "The parameters are normal, the engine is normal." ”

"Let's climb." Hang Yucheng looked at the helicopter outside with a telescope and replied into his headset.

Soon, under the operation of Hu Yuankai, Jingwei switched the climbing angle and began to climb with the nose down and the fuselage up.

The two sets of rotors of the Jingwei helicopter are similar to those of the Chinook helicopter, with the rear rotor positioned higher and parallel to the chassis, and the front rotor positioned lower and tilted forward, so that the helicopter will be more efficient when climbing.

The huge helicopter rose from the ground and quickly disappeared from the sight of Chen Shen and Hang Yucheng, and it could only be seen from the radar.

However, the connection between the helicopter and the tower has not been broken, Hu Yuankai kept reporting the flight status of the helicopter to the tower, and even in the back he was in the mood to chat with the tower about his daily life and his own control feelings.

"The current flight is going well, this helicopter is even easier to control than I expected, and this is probably the best helicopter I have ever flown other than a civilian helicopter." Hu Yuankai said in a relaxed tone while controlling the plane.

"Of course, Jingwei does not have the tail rotor of ordinary helicopters, so it is naturally easier to control." Hang Yucheng said with the same ease.

At this time, the first test flight had been carried out for more than half an hour, and the helicopter had also climbed and hovered at various altitudes around the test site as planned, and as long as there were no unexpected circumstances, it was basically certain that there would be no problems.

The unexpected did not occur until an hour later, and after all the test items were completed, Hu Yuankai successfully piloted the helicopter to the ground.

As soon as the helicopter landed, Chen Shen, Hu Yuankai and others walked up, took away the data of the test, and took the helicopter back to the workshop for disassembly and inspection, preparing for the next test flight.

Generally speaking, the test flight of a helicopter includes hovering, take-off, level flight, climbing, landing, maneuverability, environmental vibration, noise and other aspects.

There are various sub-items in these categories, and the Jingwei helicopter will only carry out a small part of it at present, and it is determined that it has the ability to fly normally and will not suddenly break down.

The rest of the performance tests, including the endurance of the load, will be transferred to the dome base test.

After all, the goal set for Jingwei Helicopter before was to hoist the mecha, so naturally it was necessary to test it in the place where the mecha was built.

And just like that, eight days passed quickly.

All the test flights of the helicopter have been completed, and as expected, there have been no major problems, except for a few minor problems that have been corrected in a timely manner.

The Jingwei helicopter will then fly to the Dome as originally planned for the rest of the tests.

At the same time, the remaining seven trial machines required by Chen Shen are also being manufactured.

As long as they are completed, they will be sent to various environments such as deserts, rainforests, and seas in China for testing as soon as possible, and after passing the test, they will also fly to the dome base to stand by.

In this way, if there is no problem with the load test, you can wait for the mech's mounting accessories to be completed, and wait for the opportunity to enter the deep-sea exploration phase of the Crimson Tempest project.

Chen Shen and the others set off before the Jingwei helicopter, and after simply packing their luggage, they took the high-speed train and embarked on the way back.

The Jingwei helicopter was teamed up by two test pilots after changing its livery and embarked on the road to the Dome Base.

The helicopter took off in the morning, and Hu Yuankai and another colleague flew to the east according to the predetermined route.

Although the flight route was carefully chosen, and there was no man's land below, there were still many people who witnessed Jingwei on the way to the flight.

There is no way, there are too many people in China, even in some seemingly deserted places, there are many travelers to explore, let alone in the densely populated east.

Moreover, because the test flight was not completely completed, Jingwei could not fly high, and the flight altitude was basically maintained within 1,000 meters, or even 500 meters.

In this way, as long as there is no problem with eyesight and hearing, you can basically find the huge Jingwei in the sky.

Of course, if you choose to fly at night, you can avoid this problem, at most there is another UFO legend in China.

But for the previous reason, the plane that is still in the state of test flight is a dangerous behavior to fly at night, the ground is dark, and I don't know how to land if something goes wrong.

Such a huge helicopter appeared in the sky, even if it was deliberately to suppress the heat, all kinds of sighting photos quickly circulated in various circles, all over the forums and chat groups, just like the first flight of Weilong.

In particular, the first eyewitness chat record was widely disseminated.

"You must not know what I just went through! This morning I watched the weather go to climb the mountain, but I only halfway up the mountain when I heard a loud noise in the sky, I thought it was thunder, and I felt like an airplane flying by, so I looked up! ”

"What happened? Don't sell it. ”

"There was a huge helicopter flying in the sky, like a hill! I was stunned! ”

"Don't say something that you don't have, you just need to say whether you have taken a picture or not."

"Who said there was no tone, I took videos and photos, but the helicopter was very fast, and when I took out my phone, it was already flying far away, and there were surrounding woods to cover it......"

Then there is a video, just like the previous one, after clicking on it, you can only see a huge black shadow rotating in the sky, which is not very clear, and it quickly disappears from the camera under the obscuration of the surrounding woods.

However, a huge sound was also captured in the video, just like the one shot under the helicopter, which belongs to the total loss sound quality that can make the headphone party die on the spot.

If there is only one sighting, it would not be convincing everyone, but there are many other witnesses besides this earliest sighting.

All of the reports took place at similar times and locations, and the descriptions and images captured were quite similar.

This makes it impossible for anyone who sees it to believe it.

It's just that some people who know a little about helicopters feel that there is a greater possibility of fraud after analyzing the video.

"The video is a foreign Chinook helicopter, and it has also been magically modified, and the size and shape are a bit mismatched, and my country has not introduced Chinook, and there is no relevant research and development plan, so these videos must be faked."

This statement is not wrong, and many people believe the claim that this video is fake, but it can't stand more and more sighting records.

From morning to noon, there were only a dozen sightings, but by the afternoon there were more than 50 sightings that were widely circulated on the Internet, and each record contained a video record, which could outline a detailed flight path through the shooting location.

Some people have even estimated that at least hundreds of different records have been seen from various chat groups and forums.

If it is only a dozen records, it is possible to forge them, but dozens or hundreds of records are obviously impossible to be forged.

In the face of reality, no matter how firm they are, people who are firm in their beliefs must bow their heads.

"But how could a helicopter so similar to Chinook suddenly appear in China? There was no movement before, and the Chinook is a little outdated now, so why do we want to copy this helicopter? ”

Indeed, although many people on the Internet believe in the Jingwei helicopter, most military fans or aviation enthusiasts cannot understand this matter.

Tandem twin-rotor configuration of the helicopter, due to a large part of the overlap between the two rotors, it will lead to a serious waste of engine power, now even foreign countries have gradually abandoned this design, and replaced with a more advanced and reasonable tilt twin-rotor helicopter.

That is, the helicopter whose rotors are often distributed horizontally on the left and right wings of the fuselage and can also be tilted forward at the same time.

This is where the next generation of helicopters is headed.

If it weren't for the fact that Chinook had already lagged behind, it would have been possible to try to imitate Chinook with the current strength of the country.

Chen Shen naturally knew about this, even if he didn't know, Hang Yucheng would tell him, but this kind of design clashes with the information given by the system, and if it is not redesigned, it will not be changed at all.

Therefore, it is better to build it according to the design of the system first, which is a little easier.

As for the later improvements, let's leave it to professionals like Hang Yucheng.

The most valuable thing in the Jingwei helicopter is its transmission system and energy system, and the other parts are not important, as long as these two systems are changed, you can build whatever helicopter you want.

It's just that no matter how strong the wind and waves in the outside world are, the first Jingwei finally arrived at the end of the flight path - over the dome base after nearly ten hours of flight, and slowly landed at the mecha test site.

"I'll go! What's that behemoth flying in the sky? Is the Great God's newly created flying mech? ”

"That's obviously a helicopter!"

"That's too big, isn't it?"

The loud sound of the helicopter alarmed the entire base, and many people poked their heads out of the windows to watch.

Everyone inside the base was alarmed, and outside the base, let alone naturally.

With such a huge size, the matter of entering the dome base from the air cannot be concealed at all, not to mention that the helicopter chose to come in from the mecha town.

In less than half an hour, there were a lot of eyewitness videos on the Internet, but because Jingwei was preparing to slow down and land, this time it was much clearer.

Someone even photographed the tail of the helicopter, with an angular mecha LOGO printed on it!
