Chapter 2123

"How much?"

"Let me see?"

“。。。”

The crowd gathered around.

Then.

You see the numbers on the screen and they start to rise.

Three hundred and six.

...

377.

...

three hundred and eight.

...

400.

"Huo!"

They could not help but be surprised. At the speed of 400 per hour, the helicopter hardly had any, and it seemed to be accelerating, breaking through 430 in less than five minutes.

Four hundred four.

...

four hundred and five.

...

four hundred and six.

And then the speed stopped and kept going.

"That's great!"

"So fast."

"It broke through 460."

“。。”

Although well-trained, but also can not help but be surprised by the number, 460 km / h, in the helicopter field, only one more than.

And then.

That one hasn't been in service yet.

"I heard it was very big? Why is it so fast? It's unscientific. Besides, is this cruise speed, or has it reached the maximum speed? "

Highest.

It is generally higher than cruise.

So.

If it's just cruising, then it represents its highest speed, which can exceed 500 km / h. This speed is really a bit shocking.

"I don't know."

"Or

"What are you doing?"

"Ask them." Due to the airspace authorization only, there are no parameters of the aircraft, which will be put on record until the test is completed.

"Kuo Yi."

"It's better to have a picture."

"Mm-hmm!"

“。。。”

They were very curious about what they looked like.

But.

In the end, the plan was not implemented, but in a different way.

Five minutes later.

From their satellite images, it's not easy to apply for this thing, but it's not that they can't apply for it. Anyway, they are usually idle.

"Wow

"Really big!"

"The beast."

"Domineering."

"I finally understand why I can fly so fast, four propellers, four turbine engines, and eight power outputs. No wonder it can be so fast."

"Cow!"

"This design, too bold."

"Yes

“。。。”

Looking at the shape, they realized how "luxurious" it was. Although the specific parameters were unknown, they did not look bad.

"I want to have a close look."

"Mm-hmm!"

"Dreams."

"This is a confidential unit. We can't let the plane come at will, but we can go and watch it. They will have a public test in a few days."

"Unfortunately, we can't go."

“。。。”

They all know that the bustle can not be achieved.

But.

The person in charge here is thinking, take people to observe, it seems that is not a big deal, winter is nothing, when to learn.

Yeah.

There can be.

。。。

Base.

Tower.

"Chairman, the air traffic control department said that he would like to visit and observe it in a few days." After receiving the news, the person in charge should report it immediately. This is not a big deal.

I can agree.

But.

Tang Qing is here. He has to ask for advice.

"Oh?"

"Good."

Tang Qing promised with a smile that, in fact, the military will send people to come in a few days. Although the helicopter plan is bold, it still attracts the attention of the superior.

In addition.

The Ministry of work safety will also come.

After all.

One of the uses is fire fighting. Although it doesn't matter whether you buy Tang Qing or not, you should ask for it. If you have an order, it's better if you don't have an order.

Anyway.

We don't eat on this.

Then.

Tang Qing continued to stare at the screen.

Now.

At full speed, the shape of the whole aircraft has changed. At more than 100 km / h, the four cantilevers are still in X shape.

Three hundred kilometers.

The fuselage became wood.

Four hundred kilometers.

Well!

There is a difference between "wood" and "wood". The horizontal direction of "wood" is gradually replaced by "^". The main reason is that the angle is not so large, and the main reason is the drag reduction.In the atmosphere.

It's easy to say that when the speed is fast, the influence of air resistance must be considered. At the speed of 400 km / h, the resistance will be very large due to the body shape.

So.

That's the design.

。。。

An hour later.

The dual power test is over.

Perfect.

There was no fault during this period. What's next? Flying or flying is still the path just now, but this time, other fault items will be added.

For example.

First item:

"left front rotor power failure."

Then.

As you can see on the screen, the aircraft slightly deviated, a little unstable, but soon recovered its posture, only the speed was lower than before.

Because.

Through the internal connection of the drive shaft, the power of the right front is dispersed. One engine drives two propellers. Of course, it will slow down.

Then.

The second item:

and the front right connecting drive shaft fails.

Left back.

It's broken again.

Right back.

All in all.

According to the design, one engine can drive four rotors to rotate together, that is to say, if three rotors are broken, the speed will be very different.

We can only guarantee that we don't crash, but we have to land quickly.

In addition.

In addition to the rotor, the turbine engine can also play an important role at this time. Eight power, switching and supporting each other brings great challenges.

However.

No matter how hard it is.

In the face of human intelligence, it can also climb. In theory, as long as there are two different outputs in a cantilever.

It won't crash like a kite with a broken string, which is almost impossible to happen unless it is hit by a weapon.

That way.

It is a complete force majeure.

。。。

An hour later.

Base.

The six aircrafts completed complex power switching under various power failure conditions. When they returned to the base, only two rotors were rotating.

And then.

Only one engine is working, and the other seven are all "out of order", although the data show that the pressure of that engine is high.

But.

It still persisted and did not exceed the critical value.

Finally.

Safely parked on the tarmac.

"Hua Hua Hua Hua!"

Tower.

Applause, excitement, this is a complete performance test, the results can only be said to be perfect. Such a complex environment can be overcome.

8. Motivation.

Seven were lost.

But they can land safely, which is the only one in the history of human aircraft design. It can be said that they made history in one year.

Now.

Tang Qing's voice sounded:

"very good."

"This test, very smooth, to the meal point, we go to eat first, the maintenance group to overhaul, the afternoon began to practical project testing."

Then.

Everyone in the tower left excitedly.

Logistics team up.

Check.

Come on.

Then we will transport the pendant out of the factory and arrange the rehearsal in the afternoon. Soon, Tang Qing received a reward: all six aircraft were OK.

In this regard.

Tang Qing is no surprise.

I'm kidding.

The equipment is all in space, and the soldiers use the most sophisticated technology and technology to manufacture, and have done hundreds of experiments before, but the skin is very practical.

It's hard to drive normally.

。。。

Tang Qing didn't know.

At an air force base thousands of miles away, as well as in the capital city, many people who watched the exercise through satellite were unable to calm down for a long time.
