Chapter 2122

Generally speaking.

This is a factory test.

So.

If it is officially put into use in the future, we should take care of it. On the instruction manual, I will never suggest: Park at random, if it breaks down, I will lose.

It's bullshit!

In fact.

Wind.

Rain.

Snow.

Ray.

...

it is competent in all kinds of environments.

However.

In the manual, it will definitely write:

1. It is not recommended to take off without preheating after parking for more than an hour at zero.

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

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

...

the matters needing attention in tens of items and hundreds of pages should not be vague. Just like various military equipment, it can work in various harsh environments at the beginning of design.

But.

No one dares to write in the operating manual: this thing is rough, you can do it!

。。。

The next day.

In the morning.

It's a pity that it's still very cold when standing in the sun. It's cool to absorb a lot of heat when the snow melts around.

Canteen.

After a delicious breakfast, everyone went back to their posts. Today, they are going to start a rehearsal of the whole project. They are very nervous, for fear of something wrong.

Ten o'clock.

Tower.

Top floor.

The decoration here is quite sci-fi, three arc-shaped console, dozens of people sitting next to the computer, busy up, computer screen is glass.

Yeah!

It's like the movie, transparent, touch screen, but it's still mainly operated by the mouse to avoid accidental touch. It can't be too handsome.

Some things are good.

But.

Also need to consider the reality, as well as the problem of docking with external data, many professional software only support the mouse, change will take some time.

。。。

They have a lot of tasks.

Scheduling.

Command.

Contact.

Although this kind of take-off is only at medium and low altitude, and it is a place where people can't reach, it still needs to obtain the flight permission from the airspace management department.

Among them.

Only 300 meters above the base area is not required to apply.

Cumbersome.

But as long as you can fly.

"Report, permission for rehearsal has been obtained!" The liaison officer reported that this is not a civil aviation control area. Therefore, it is necessary to apply to the air force unit.

Generally, they will not refuse.

Unless.

There are missions and other special circumstances in this area, but it is very remote here. Even if there are fighter cruises, there will be no conflict with helicopters.

The heights are different.

So.

So far, it has not been rejected.

"Good."

"Start the first item."

"Yes."

Give me an order.

Suddenly.

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

。。。

"Speed 50, normal."

“。。。”

"Speed 80, normal."

“。。。”

"Speed 100, normal."

“。。。”

The information kept coming, and it soon broke through 200 kilometers. Because it was empty, such a speed did not reach the limit of this aircraft.

It's still increasing.

"Speed two hundred three, normal."

“。。。”

"Speed two hundred seven, normal."

“。。。”

"Speed 300, normal."

“。。。”

Finally.

At this time, they disappeared into the view of the tower. According to the plan, they would fly 120 kilometers at 300 meters low altitude.

Then.

Climb.

One thousand meters.

Two thousand meters.

Four thousand meters.

Six kilometers.

A total of four altitudes, each flying for 20 minutes. Previously, only one altitude was tested each time. This time, the projects were tested together.

Six kilometers.

Lower than the height of civil aircraft is the limit of design. It's not that you can't fly higher, but it's unnecessary. The main purpose of this thing is not shipping.

There's no need to go to the sky, side by side with the airliner.

。。。

"Speed 360, stable flight, normal state!"“。。。”

"Speed 360, stable flight, normal state!"

“。。。”

Report every minute.

At this point.

In front of the huge glass screen, Tang Qing stood with his hands down and stood still. On the screen were the running positions of six aircrafts, which were guided by GPS.

No way.

I want to use Beidou.

It's going to be years. In 2000, the Beidou series of satellites began to be launched, but in 2007, the first Beidou navigation satellite was launched.

Then.

Two years later.

The second Beidou navigation satellite was launched in April this year, and at least three satellites are needed to achieve precise positioning of a point.

Longitude.

Latitude.

Height.

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

So.

Beidou really has the function of high-precision positioning. We will have to wait until the end of next year and launch two more to form a basic positioning array.

。。。

On the screen.

You can only see the location of the map, but not the object.

But.

In Tang Qing's eyes, however, he could see that the real-time images from his own satellites in the sky were extremely clear and could even be traced at high speed.

I can see the driver. It's pretty good.

At the same time.

Countless information flashed through the corner of the eye, that is the operation of the equipment.

Normal.

Normal.

Normal.

There's not a single alarm.

"1000 meter 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 it had to go the same way again.

But.

We need to speed up this time.

"Start the second item, no load, full power ahead."

"Yes."

With the command, the aircraft goes back on the road, climbs very fast to the propeller powered cruise speed, and then, in the middle of the boom.

"Buzz!"

The vertical turbine engine starts to spin and becomes horizontal.

"Buzz!"

“。。。”

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

"Secondary power, output 10 percent."

“。。。”

"Secondary power, 30 percent output."

“。。。”

I see.

Six more aircraft in the sky.

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 difficult without Boeing's aero-engine, and the aircraft is hybrid. Therefore, the performance requirements of aeroengine are much lower.

It's powerful.

Light weight.

That's enough.

It's OK to be rough, stable output and meet the requirements. Under extreme simplification, the engine parts are reduced by two thirds.

All in all.

If you can use it, you can use it.

。。。

A thousand miles away.

An air force base.

Tower.

Airspace control center.

"The speed is still very fast, 360, in the helicopter field, is also considered to be the best, but very strange, why is the application speed of 500 km?"

"Who knows."

In fact, they did not have a heavy task in one day. They suddenly appeared civil test flight. They were very curious. They all looked at the moving light spots on the screen and talked about it one after another.

In this regard.

Most of them are fresh.

After all.

How to say it was designed by Tang Qing, military? Forget it. It's too big, too conspicuous and an absolute target, even if it's not suitable to transport materials.

Suddenly.

The screen flashes.

"Speed up!" One was surprised.
