Generally speaking.
This is a factory test.
So.
If it is put into use in the future, we should take care of it. On the instruction manual, there is no suggestion: Park casually, if it breaks, I will lose.
That's bullshit!
In fact.
The wind.
Rain.
Snow.
Ray.
...
it is competent in all kinds of environments.
However.
It will definitely be written in the manual:
1. It is not recommended to take off without preheating after parking for more than one hour in zero degree environment.
2. It is not recommended to park outdoors for a long time.
3. Take off in dusty weather is not recommended.
...
the notes of dozens of articles and hundreds of pages should not be ambiguous. Just like military equipment, it can work in various harsh environments at the beginning of design.
But it's not.
No one dares to write in the operation manual: this thing is rough, you are free!
。。。
The next day.
Early in the morning.
It's a pity that standing in the sun is still very cold. When the snow melts around, it needs to absorb a lot of heat and cool.
Canteen.
After a delicious breakfast, everyone went back to their posts and started a preview of the whole project today. They were very nervous for fear that something might go wrong.
Ten o'clock.
Tower.
The top floor.
The decoration here is quite sci-fi. There are three arc-shaped control panels. Dozens of people sit beside the computer and get busy. The computer screen is glass.
Yeah!
It's like in the movie, transparent, touch-screen, but still mainly using the mouse operation, to avoid false touch, Shuai can't be too much.
Some things are good.
But.
We have to consider the reality and the problem of data docking with the outside world. Many professional software only supports mouse, so it will take some time to change.
。。。
They have many tasks.
Dispatch.
Command.
Contact.
Although this kind of take-off is only at medium and low altitude, and it is a place rarely visited by people, it is still necessary to obtain a flight permit from the airspace management department.
Among them.
Only 300 meters above the base area does not need to apply.
Cumbersome.
But as long as you can fly.
"Report, preview permission to take off has been obtained!" The liaison officer has come to report that this area is not under civil aviation control. Therefore, he needs to apply to the air force.
Generally, they don't refuse.
Unless.
There are missions and other special situations in this area, but it's very remote here. Even if there are fighter cruises, it won't conflict with helicopters.
The heights are different.
So.
So far, it has not been rejected.
"Good."
"Start the first one."
"Yes."
Give me an order.
All of a sudden.
Six helicopters started to power, straight up into the sky, and then, four huge propellers began to tilt, driving the aircraft forward.
。。。
"Speed 50, normal."
“。。。”
"Speed 80, normal."
“。。。”
"Speed 100, normal."
“。。。”
Information kept coming, and soon broke through 200 kilometers. Due to no-load, this speed has not reached the limit of this aircraft.
It's increasing.
"Two hundred and three, normal."
“。。。”
"Speed 27, 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 a low altitude of 300 meters.
Next.
Climb.
One thousand meters.
Two thousand meters.
Four thousand meters.
Six kilometers.
There are four altitudes in total. Each altitude flies for 20 minutes. Before that, only one altitude was tested at a time. This time, the project was connected.
Six kilometers.
Being lower than the height of a civil aircraft is a design limit. It's not that you can't fly higher, but it's unnecessary. The main purpose of this thing is not shipping.
You don't need to go to the sky, side by side with the airliner.
。。。
"Speed is 36, flight is stable and normal!"“。。。”
"Speed is 36, flight is stable and normal!"
“。。。”
Report every minute.
At this point.
In front of the huge glass screen, Tang Qing stands with his hands in the air, standing quietly. On it are the running positions of six aircraft, using GPS navigation.
No way.
I want to use Beidou.
It's going to take years. Beidou series satellites were launched in 2000, but the first Beidou navigation satellite was launched in 2007.
Then.
Two years later.
In April this year, the second Beidou navigation satellite was launched. To achieve accurate positioning of a point, at least three satellites are needed.
Longitude.
Latitude.
Height.
Generally, there will be one more for correction and standby.
So.
Beidou really has the function of high-precision positioning. It will have to wait until late next year to launch two more satellites to form a basic positioning array.
。。。
On the screen.
You can only see the location of the map, but not the real object.
However.
In Tang Qing's eyes, however, he could see that in the sky, his own satellite had sent real-time images, which were extremely clear and could even be tracked at high speed.
I can see the driver. Pretty good.
At the same time.
Innumerable information flashed by the corner of the eye, that is the operation of the equipment.
Normal.
Normal.
Normal.
Not a single alarm.
"The 1000 meter fixed cruise is completed, the speed is 36, the whole journey is normal, and there is no equipment alarm."
“。。。”
"The 3000 meter fixed cruise is completed, the speed is 36, 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.
However.
We need to speed up this time.
"Start the second, no-load, full power forward."
"Yes."
On command, the aircraft is on its way again, climbing very fast to the cruise speed of propeller power, and then, in the middle of the cantilever.
"Buzz!"
The vertical turbine engine starts to spin and becomes horizontal.
"Buzz!"
“。。。”
The sound is getting louder and louder. In the end, it's almost roaring. It's inevitable that there is such a noise. The sound of vortex shaft + turbine and air friction is not small.
"Secondary power, 10 percent output."
“。。。”
"Secondary power, 30 percent output."
“。。。”
I can only see.
Six more vehicles 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's not as difficult as Boeing's aero-engine, and the aircraft is a hybrid, so the performance requirements for aero-engine are much lower.
It's exciting.
Light weight.
That's enough.
It's OK to be a little rough, stable output, and meet the requirements. Under the extreme simplification, the engine parts are reduced by two-thirds.
All in all.
If you can use it, you can use it.
。。。
Thousands of miles away.
An air force base.
Tower.
Airspace control center.
"The speed is very fast. It's 36 kilometers. It's also a leader in the helicopter field. It's just very strange. Why is the application speed 500 kilometers?"
"Who knows."
In fact, their mission was not heavy one day. Suddenly, they had a civil flight test. They were very curious. They all looked at the moving light spots on the screen and talked about it.
In response.
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. It's not suitable even for transporting materials.
All of a sudden.
The screen flashed.
"Speed up!" One was surprised.
