Chapter 493 Regional Airliner MT90 and MT60
Chang'an, the capital of the west, as the ancient capital of thousands of years, Chang'an has too many places of interest and historical sites worthy of admiration, to feel the glory and magnificence of the majestic China in the past.

Chen Huaiqing came to Xidu at this time, naturally there was a reason.

Mota Aircraft is in Xidu.

In the field of aviation, Murta Aircraft seems to belong to that kind of standard newcomer.

However, those who are familiar with the Murta aircraft are very clear that in the field of research on large transport aircraft, the Murta aircraft is the number one in China.

Mota Aircraft took over the design and development team of Y10 in its entirety, and also took over all the aircraft design and development personnel from Xidu Aircraft Factory.

Xidu Aircraft Factory is now focusing on the field of aircraft manufacturing, and the research and development is carried out by Mota Aircraft.

Xidu Aircraft Factory is one of the major shareholders of Murta Aircraft.

Mota Aircraft not only studies civil aviation airliners, but also conducts research on military transport aircraft.

The Gulf War allowed everyone to see the powerful global deployment capabilities of foreign powers. In a short period of time, hundreds of thousands of troops were directly deployed in place.

In addition to the army, various weapons and equipment were transported over.

Among them, the role of transport aircraft can be extremely huge.

In the Xidu Aircraft Manufacturing Plant, Chen Huaiqing looked at the aircraft in the factory room being slowly pulled by a professional aircraft trailer.

This is a regional airliner.

Compared with the mainline airliner, this aircraft is naturally a little inferior in terms of passenger capacity.

It can carry 98-114 passengers, plus 6 crew members.

The entire aircraft is designed and manufactured in accordance with the standards of European and American civil aviation airliners.

In terms of the development of civil aviation airliners, it has been decided before that it will not take the route of large airliners, but focus on the regional airliner market first.

Accumulate the experience of manufacturing civil aviation airliners first, and then carry out the research and development of large airliners.

In 2010, realize independent research and development and independent production of civil aviation large passenger aircraft.

Including avionics, engines, aircraft materials, etc.

The ultimate goal is to achieve independent control of the entire aviation industry chain.

"Chen Dong, this is the second prototype we have assembled. After passing various tests, if everything goes well, we can apply for airworthiness certification test flight after one year."

The plane is flying in the sky, so all kinds of tests must be strictly carried out.

European and American civil aviation aircraft standards are indeed high, but under the requirements of high standards, higher requirements are put forward for design and manufacturing.

Huaguo's R&D personnel are not afraid of high standards.

With the support of sufficient research and development funds, the aviation industry has made rapid progress in these years.

Chen Huaiqing flipped through the booklet in his hand, the booklet was still very beautifully made.

A basic situation of the aircraft is marked above.

Regional airliner code: MT90
Length of the fuselage: 36.2 meters

Wingspan length: 28.72 meters

Fuselage height: 10.28 meters

Internal height: 2 meters

Engine: Mota KE (Kua'e) A1 engine
The Mota KE-A1 engine is a high bypass ratio turbofan engine with a thrust of 63.74 kN (6.5 tons force) and a total of 1.75 tons.

This is an engine specially developed for the MT90 aircraft. Since the establishment of the MT90 project, the development of this engine has also begun.

Previously, in addition to receiving the Y10 R&D team, Mota Aircraft also took over the Y10 supporting turbofan 8 engine R&D team.

This engine research and development team has gone through the complete process of aircraft engine research and development through the research and development of Y10 supporting engines.

In other words, they are an experienced aircraft engine research and development team.

After taking down the aircraft engine research and development team, the Rongcheng Aircraft Engine Factory was acquired.

The research and development strength in the field of aircraft engines has been strengthened.

In the past few years, there has been a constant search for aircraft engine talents.

Of course, self-cultivation is also carried out.

Therefore, although there are still great difficulties in the development of the Mota KE-A1 engine, it is still done.

The condition of the KE-A1 engine is quite good, and the performance of the static test is stable after 1000 hours of continuous operation.

To be able to develop the KE-A1 engine, we must also talk about the progress of the Metal Materials Research Institute of the Mota Technology Research Institute in high-temperature alloy materials.

Engine turbine blades generally operate under severe conditions of 1500°C and close to 15000 rpm, which is a huge centrifugal force.

Turbine blades have high working temperature, heavy load and complex stress.

It is also required that the material has strong thermal strength, impact resistance, fatigue resistance, corrosion resistance and damage tolerance characteristics.

The material is like rice!

Make bricks without straw.

The avionics system was developed by Mota Aircraft itself, and the chips used in the aircraft are all technically supported by Sixiang Technology.

A lot of data about the MT90 aircraft can only be determined after testing.

For example, the maximum take-off weight, the maximum load, the minimum take-off runway distance and so on.

There will be a gap between the design data and the actual data that can be achieved due to various reasons.

If it is said that one day the design and actual error can be made very small, then it will be very powerful.

At that time, Huaguo's aviation industry really entered the room.

This is not just a small gap, but also involves many problems behind it.

Many things seem simple, but there is a system behind them.

Just like cars, the production of cars can be done easily in Huaguo at this time.

But on a global scale, there are not many countries that can produce cars.

There are even fewer that can do a good job in the automobile industry.

No way, this belongs to a whole set of industrial systems.

Chen Huaiqing: "How is the flight test of MT60?"

The MT60 is not a jet, but a twin turboprop aircraft.

In terms of design standards, it is also in accordance with the standards of European and American civil aviation airliners.

MT60 is not just about wanting to compete only in the Chinese civil aviation passenger aircraft market, but to go to the international market and obtain European and American airworthiness certificates.

Obtaining European and American airworthiness certificates at this time, basically Europe and the United States will not restrict the MT60. After all, the two are now focusing more on large civil airliners.

For such a small aircraft, look down on.

After all, small planes don't make money at all. They worked so hard to sell one, and eventually earned hundreds of thousands...

How profitable it is to sell large planes, at least tens of millions or even hundreds of millions per plane.

Compared with the localization of the engine on the MT90, the engine of the MT60 is outsourced.

The development of turboprop engines has been quite long, and the long period of time has naturally led to the maturity of technology.

Therefore, there are quite a lot of options for MT60 outsourced engines, and I chose an engine manufacturer in the United States.

It belongs to a not too well-known engine manufacturer.

The engine is outsourced, but the avionics system of the MT60 is still self-developed.

Except for the engine, everything else is localized.

At this time in Huaguo, the only domestic civil aviation passenger aircraft was the Yun-7 aircraft, which was a copy of the Soviet An-7 aircraft.

MT60 is developed on the basis of Yun-7. Of course, it has been improved in many places.

In fact, compared with Yun-60, MT7 is completely different.

In terms of design standards, they are all very different. In addition, the technology adopted by MT60 is more advanced.

Although the time interval between MT60 and Yun-7 is not too long, it must be known that Yun-7 was put into the field of civilian passenger transport in 1986.

In just a few years, technological progress has been so great?
It's a very normal thing, Mota Aircraft has this technical strength at this time.

Murta Aircraft recruited many aircraft design experts from Ulank to take up positions.

In fact, this year, it has become much easier for Murta Aircraft to recruit aircraft design experts from Ulank.

I'm going to be hungry, so naturally I have to find a way to continue my life.

Xidu Aircraft Manufacturing Factory and Wulanke still have a lot of cooperation, so under such circumstances, it seems very normal to want to recruit some people.
