Rebirth

To

generally speaking.

This is a manufacturer test.

So.

If it is officially put into use in the future, we still need to take care of it. In the instruction manual, it is absolutely not recommended: just park it, if it breaks, I will lose.

What a fuck!

Actually.

Wind.

Rain.

Snow.

Ray.

……

It can handle all kinds of environments.

However.

In the manual, it will definitely write:

1. It is not recommended to take off without warming up after parking for more than one hour in a zero-degree environment.

2. It is not recommended to park outdoors for a long time.

3. It is not recommended to take off in sandy weather.

……

Dozens or hundreds of pages of precautions should not be vague. Just like all military equipment, it can work in various harsh environments at the beginning of its design.

But.

No one dares to write in the operating manual: This thing is rough, you are free!

. . .

The next day.

Early morning.

Under the warm sun, it’s a pity that standing under the sun is still quite cold. When the surrounding snow melts, it will absorb a lot of heat and it will be chilly.

Canteen.

Eat a perfect breakfast, everyone returned to their posts. Today, a preview of the whole project is about to begin. They are all very nervous, for fear of any problems.

Ten o’clock.

Tower.

Top level.

The decoration here is quite sci-fi, with three curved consoles, dozens of people sitting next to the computer, getting busy, the computer screen is glass.

Yeah!

It’s like the kind in the movie, transparent and touch screen, but the mouse is mainly used to avoid accidental touch, and it can’t be too handsome.

Some things are good or good.

But.

We also have to consider the actual situation and the problem of docking with external data. Many professional software only supports the mouse, and it takes some time to change.

. . .

They have many tasks.

Scheduling.

Command.

Contact.

Although this kind of take-off is only at medium and low altitudes, and is a deserted place, it still needs to obtain a flight permit from the airspace management department.

Among them.

Only 300 metres above the base area, no application is required.

Trivial.

But as long as you can fly.

“Report, the rehearsal takeoff permission has been obtained!” The liaison officer reported that this is not a civil aviation control area, so it needs to apply to the air force unit.

Generally, will not refuse.

Unless.

There are special situations such as missions in this area, but it is very remote here, even if there is a cruise of a fighter plane, it will not conflict with a helicopter.

The height is different.

So.

Have not been rejected so far.

“Good.”

“Start the first item.”

“Yes.”

Order it.

Suddenly.

Six helicopters started up their horsepower and went straight up into the sky. Then, four huge propellers began to tilt, driving the aircraft forward.

. . .

“Fifty speed, normal.”

“…”

“The speed is 80, normal.”

“…”

“The speed is 100, normal.”

“…”

Information kept coming, and it quickly broke through 200 kilometers. Because it was unloaded, this speed did not reach the limit of this aircraft.

Still increasing.

“The speed is two hundred and three, normal.”

“…”

“The speed is 270, normal.”

“…”

“Three hundred speed, normal.”

“…”

Finally.

Stabilized at the cruising speed-360 kilometers. At this time, they disappeared from the tower’s sight. According to the plan, they would fly 120 kilometers at a low altitude of 300 meters.

Next.

Climb.

1000 meters.

2000 metres.

Four 1000 meters.

Six 1000 meters.

There are four altitudes in total, and each altitude is flying for 20 minutes. Previously, only one altitude was tested each time. This time, the items were connected together to test.

Six 1000 meters.

Below the height of a civil aviation aircraft is considered a design limit. It is not that it cannot fly higher, but it is unnecessary. The main purpose of this thing is not shipping.

There is no need to go to heaven, side by side with the airliner.

. . .

“The speed is 360, the flight is stable, and the state is normal!”

“…”

“The speed is 360, the flight is stable, and the state is normal!”

“…”

Report every minute.

At this time.

In front of the huge glass screen, Tang Qing stood with his hands behind and stood quietly. On it are the operating positions of the six aircraft, using GPS navigation.

No way.

I want to use Beidou.

We have to wait a few years. The Beidou series of satellites began to be launched in 2000, but in 2007, the first Beidou navigation satellite was launched.

Subsequently.

Two years have passed.

In April of this year, the second Beidou navigation satellite was launched. To achieve precise positioning of a point, at least three satellites are required.

Longitude.

Latitude.

Height.

Generally, there will be one more for correction and backup.

So.

Beidou really has a high-precision positioning function. You have to wait until late next year to launch two more to form a basic positioning array.

. . .

On the screen.

Only the map location can be seen, not the actual object.

However.

In Tang Qing’s eyes, he can see, in the sky, his own satellite, real-time images are sent, which are extremely clear and can even be tracked at high speed.

I can see the driver, very good.

At the same time.

Countless messages flashed through the corner of my eyes, that was the operation of the equipment.

Normal.

Normal.

Normal.

Not a single warning.

“The 1000 meters fixed cruise is completed, the speed is 360, the whole journey is normal, and there is no equipment alarm.”

“…”

“The 3000-meter fixed cruise is completed, the speed is 360, the whole journey is normal, and there is no equipment alarm.”

“…”

One hour and twenty minutes later, the aircraft hovered over the base, and did not come down, because I had to walk the same way again.

However.

I want to speed up this time.

“Start the second item, no-load, full power forward.”

“Yes.”

Get the order, the aircraft got on the road again, climbed to the propeller-powered cruising speed at a very fast speed, and then, in the middle of the cantilever.

“weng weng!”

The vertical turbine engine began to rotate and became horizontal.

“weng weng!”

“…”

The sound is getting louder and louder. In the end, it is almost roaring. Such noisy is inevitable. The vortex shaft + turbine, the air friction sound is not small.

“Secondary power, output 10%.”

“…”

“Secondary power, output 30%.”

“…”

See you.

In the sky, the speed of the six aircraft increases again.

It jumped out. At the beginning of the design, Tang Qing used two kinds of power, one is the propeller, the other is the turbine located in the middle of the cantilever.

Of course.

Technically, it is not as difficult as Boeing’s aero engine. The aircraft is hybrid. Therefore, the performance requirements for aero engines are much lower.

Energetic.

Lightweight.

Suffices.

It’s okay if it’s rougher, stable output, and meet the requirements. Under extreme simplification, engine parts are reduced by 2/3.

In short.

It can be used, and the skin is solid.

. . .

A thousand miles away.

An air base.

Tower.

Airspace Control Center.

“The speed is quite fast, three hundred and six. In the field of helicopters, it can be regarded as a leader, but it is very strange, why the application speed is 500 kilometers?”

“Who knows.”

In fact, they did not have a heavy task in a day, and suddenly there was a civilian test flight, they were very curious, and they all looked at the moving light spots on the screen, discussing spiritedly.

About this.

It’s mostly fresh.
