What is the level of sound of 72 decibels?

The normal voice is slightly louder.

In the airplane, such decibels are acceptable.

“The noise at the rear and front is slightly less.”

When riding on the plane, the middle part has the greatest noise, so there is no need to say more, because the engine is there.

It must be noisy when it is close to the engine.

Han Songlin nodded gently. It is already good that this regional aircraft can achieve this level.

"Considering that our Xinzhou 700 is just a regional passenger plane and generally has a short flight time, we try to reduce other spaces in addition to the toilet and improve the efficiency of space utilization on the plane."

Above the large passenger plane, the flight attendant also has a special seating area and a place to prepare meals for passengers.

Sorry, there is no one on Xinzhou 700.

Xinzhou 700 must reduce operating costs as much as possible for airlines.

As for the flight attendant, there are two flight attendant positions on Xinzhou 700.

Moreover, the flight attendant's location is in the cabin, facing the passengers.

If the airline can get a flight attendant in order to save money, and then sell the ticket for another flight attendant.

Naturally, there are no first-class business seats or other things on the Xinzhou 700.

Regional planes usually fly to small cities, and these are not available.

“In the seat, we made it more spacious considering the comfort of the passengers!”

Han Songlin sat down and felt it. With his height, he didn't feel the crowd.

To be honest, the comfort of taking a plane is really worse than that of high-speed rail.

The seats on the plane are too dense, giving a sense of urgency.

"We also configured a personal entertainment system on the plane, with a headphone jack here, which allows you to listen to music and play music out."

Han Songlin looked at it curiously and said, "Is there a TV?"

I don't seem to see the TV!

"This, because considering that this is the application scenario of Xinzhou 700, it usually takes short flights, and the flight time is not long, and it is only more than an hour at most. It can't be watched a movie, so there is no TV configured."

It would be great to be able to configure music. Do you still want a TV?

over thinking.

This aircraft cannot require too many functions, the more expensive it is.

The airlines that operate such regional aircraft are generally not wealthy airlines.

Han Songlin opened the suitcase above his head and looked at it, and was able to hold some packages that he had with him.

As for big suitcases, I naturally have to check my luggage.

The design and layout of the entire cabin are relatively good, and the taste of a modern passenger aircraft.

Han Songlin also went to see the cabin layout of Xinzhou 60, and the whole feeling was a bit rough.

Xinzhou 700 completely got rid of this and seemed particularly tall and outstanding.

The first impression is that this plane is very good.

The domestic production rate of the entire Xinzhou 700 reaches 100%, which means that all the components of the aircraft can be produced.

The avionics and control systems of each unit are domestically produced, which is particularly important.

After flying west from Xinghai to Rongcheng, Han Songlin went to Xinghai helicopter to take a look. The official name of the guy is Xingzhi-20, which means that he can carry 20 tons.

Xingzhi-20 sold well, and the army loved it very much, so they bought four Xingzhi-20 one after another.

The price of Xingzhi-20 is not cheap either, it costs 60 million per aircraft.

In addition to Xingzhi-20, Xinghai helicopters also produce medical rescue helicopters.

Chunmang helicopter was also formally finalized and Shuchuan purchased ten Chunmang helicopters to support the development of Xinghai helicopters.

A fleet of air medical rescue aircraft has been established, but the frequency of use is slightly less.

These helicopters were distributed to cities below Shuchuan, and were usually used to transport critically ill patients to Chengdu.

Rongcheng can concentrate the best medical resources in the entire southwest region.

Chunmang helicopters are not only sold in the country, but also abroad, for example, some people need to use helicopters to transport patients.

For example, in some countries where there are a large number of islands, it becomes necessary for employees with inconvenient transportation to transport patients with helicopters.

Chunmang helicopter's performance in exports is pretty good.

Next, Han Songlin went to Fuxinghang to power again.

Fuxing Dynamics has always had a very good financial situation before.

Since entering the field of aircraft engines, Fuxing Power has begun to suffer losses.

Moreover, there is a tendency to increase in the range of losses.

This is a bit troublesome.

Han Songlin had to consider whether to separate the power of Fuxing Airlines from Fuxing Power.

After all, Fuxing Power has developed so well, there is no need to affect the development of Fuxing Power because of Fuxing Power.

At this time, Fuxing Airlines' power is becoming more and more busy, and the factory is producing the Manniu-2 engine.

As an improved version of the Manniu engine, the Manniu-2 engine can be developed so quickly, which is inseparable from experts from Eastern Europe, especially from Ukraine.

I have obtained too many various engine technologies from Ukraine. Over the years, Fuxing Airlines has been continuously absorbing its power.

While absorbing, research is also being conducted.

Fortunately, China has no shortage of Russian talents, so there is no problem in understanding the technical information they get.

In addition, China and the former Soviet Union also have a consistent meaning to a certain extent, and it is really fast to learn it.

As a good student, learning from one example and introducing new things is a necessary skill.

Obviously, China has always been a good student, not only learning from a certain country, but learning from the whole world and then integrating it.

For example, the engine in front of you!

Dynamic-10 engine!

This engine was specially developed for the Xinzhou c190.

Now the pneumatic performance experiment of the Dynamic-10 core machine and fan have completed, and the first verification machine will be installed in the future.

The research and development progress is quite fast, because there are not so many restrictions within the power of Fuxing Airlines.

The Dong-10 engine project is a project directly approved by Han Songlin. The R&D funds of the entire project can be guaranteed, and the entire R&D team will focus on R&D without considering other things.

In addition, there are sufficient staff in the entire project team, and there are also many tools to assist in R&D for each project.

For example, supercomputer.

Supercomputer is built with Luwu chips. It is not the fastest in the world in terms of computing speed, but it is still possible to meet some research needs.

Supercomputing was developed by the Supercomputing Institute of Xingchen Academy. As for the location where supercomputing was established, it is in Rongcheng.
