The first flight was successful, and where is the cow in China s domestic Qi Fighting Machine C919

C919 is cattle for the following reasons:

1. There are only three companies in the world that can produce C919 passenger aircraft, Boeing in the United States, Airbus in Europe and Tu series in Russia. But the most widely used airliners in the world are still Boeing and Airbus, and basically all the planes in the world are produced by these two companies. If China can produce it, it will be the third passenger aircraft in the world that can be used on a large scale.

Russian airliners have not been used on a large scale for a variety of reasons, including technical reasons.

2. The emergence of C919 makes Chinese aviation aircraft safer. Neither Boeing nor Airbus can guarantee that there is no secret door procedure in the aircraft, and in special cases, the manufacturer can directly take over the control of the aircraft. For example, the disappearance of a Chinese plane in the South China Sea is actually known to all the manufacturers of this information.

Because the flight data will be constantly transmitted back to the manufacturer, but they just don't report it. There are too many such conspiracies. The C919 does not exist at all, because it is produced by itself, and the control system is its own.

3. C919 has the ability to compete with Boeing and Airbus. According to statistics, China will need another 6,000 passenger planes by 2030, which will cost about $1 trillion. If China can produce it itself, then the cost will inevitably be greatly reduced, and China will no longer need to spend so much money to buy planes.

The C919 had already had 570 orders before it was released, which made Boeing and Airbus very unhappy, because these orders were originally theirs.

4. In other aspects, the modification potential of C919 is very large. For example, the American P8 submarine reconnaissance plane was modified from a passenger plane. In the future, China can use the C919 to modify it into the model it needs.

There are not many countries in the world that can build such large aircraft, probably less than 5.

The successful maiden flight of this aircraft is of great significance to our country, which can make our mood better and relieve our mood, and can also make the whole world prove that our economy and our aircraft are not in trouble.

The first flight of the domestic large aircraft C919 was successful, which is very successful for our country, which is developing science and technology and progressing.

Economically, the C919 is a stepping stone. It has helped China's aviation industry squeeze into a market for the world's aviation industry, and this is its greatest significance.

China's C919 large passenger aircraft is China's first mainline civil aircraft with independent intellectual property rights in accordance with the latest international airworthiness standards, designed for short-range to medium-haul routes, and began to be developed in 2008. C is the first letter of China, but also the first letter of COMAC English abbreviation COMAC, the first "9" means forever, "19" represents China's first medium-sized passenger aircraft with a maximum capacity of 190 seats.

The C919 large passenger aircraft is the first jet trunk airliner developed by China in accordance with international airworthiness standards and has independent intellectual property rights, which was established in 2007 and made its first flight in 2017. The C919 large passenger aircraft was successfully developed and obtained the type certificate, marking that China has the ability to independently develop world-class large passenger aircraft, and is an important milestone in the development of China's large aircraft industry.

Features of C919:

In terms of materials, C919 will use a large number of advanced composite materials, advanced aluminum-lithium alloys, etc., of which the use of composite materials will reach 20%, and then through the detailed design of the aircraft's internal structure, the weight of the aircraft will be compressed.

In addition, the C919 will use domestic aluminum alloy, titanium alloy and steel and other materials that account for 20-30% of the structural weight of the whole aircraft, which fully reflects the ability and future trend of the C919 large passenger aircraft to drive the domestic basic industry. At the same time, due to the large number of composite materials, compared with the 80 decibels of the cabin noise of the same type of foreign aircraft, the noise in the C919 cabin is expected to be reduced to less than 60 decibels.

In terms of emission reduction, the C919 will be an advanced aircraft with green emissions and environmental protection requirements, and is expected to reduce the carbon emissions of the aircraft by 50% compared with similar aircraft through the environmentally friendly design concept.

The C919 features a four-sided windshield. This technology is the most advanced technology in the world, only the latest Boeing 787 is used in the trunk airliner, its windshield area is large, the field of vision is wide, due to the relatively few openings, the fuselage processing industry is simplified, and the aerodynamic drag of the head of the aircraft is reduced.

The news of the great success of China's first C919 large aircraft in the first flight test of the first user is about to be delivered to the first user has spread all over the country through the Internet, and countless netizens have cheered for it. A large C919 aircraft numbered B-001J took off from the 4th runway of Pudong Airport and landed safely at 9:54 after more than 3 hours of flight。During the whole process, the test pilot and the test flight engineer worked closely together with each other to successfully complete the scheduled tasks, and the aircraft was always in good condition and performance.

What are the advantages of comparing Boeing and Airbus with the same type of large aircraft? In this regard, relevant industry insiders said that relatively speaking, the domestic large aircraft C919 is a rising star, with more advanced technology and a higher degree of automation in the overall design, and at the same time, the market potential in the future is also more advantageous. The cabin width of the domestic large aircraft C919 is looser than that of the Airbus A320 and Boeing 737, the passenger experience and cabin comfort are better, the cargo compartment volume is larger, the cargo capacity is better than that of Boeing and Airbus, or it has more commercial space.

In ten years, if China can make C919 stable and steady, and do a good job in the quality and performance market, it will be a great progress in China's aviation industry. We must take one step at a time, be down-to-earth, make up for the backwardness, lay a solid foundation, accumulate steadily, and look forward to the delivery of China Eastern Airlines this year. At that time, the passenger aircraft market, which was originally dominated by Boeing and Airbus, will also be replaced by China.

Boeing aircraft accidents continued, the reputation of the Boeing Group deteriorated, and the quality of the aircraft was questioned. May China's independent civil aviation large-scale commercial aircraft be more advanced!

Excitedly, C919 finally arrived at the time of delivery, lamenting that this step is really not easy, is the crystallization of countless Chinese's hard work and sweat, paradoxically, this model of aircraft in the country has a lot of controversy, mixed reviews. After a lot of tempering, C919 finally made its debut at this moment, allowing people to see a glimmer of hope in looking forward to China's goal of becoming an "aviation power".

Because this aircraft is not purely domestic, and everyone is afraid that the fuselage structure is not done well and is unstable.

Because our country has made great efforts in this regard, and the final results are not satisfactory, but our country still has a lot of room for progress.

The successful first flight of the domestic large aircraft C919 shows that China's science and technology have been further improved, and I believe that our motherland will become stronger and stronger.

At 15:19 on May 5, 2017, the C919 large passenger aircraft made its first flight at Shanghai Pudong Airport. On its first flight, the C919 flew at a maximum altitude of 3,000 meters and a maximum flight speed of 170 knots.

In July 2017, the second flight test aircraft of the domestic large passenger aircraft C919 carried out on-board functional inspection tests, and the development of the first flight of C919 in the fourth quarter embodies the efforts of hundreds of thousands of scientific researchers in China. According to statistics, 22 provinces, more than 200 enterprises, 36 universities, and hundreds of thousands of industrial personnel have participated in the development of the C919 large passenger aircraft.

On September 9, 2017, 10101 C919 large passenger aircraft carried out taxiing test for the first time on the fifth runway of Pudong Airport. On the same day, at the "Lightweight Materials Industry Development Forum" of the 2017 China Top 500 Enterprises Summit Forum, Cao Chunxiao, an academician of the Chinese Academy of Sciences and a researcher at AECC Aviation Materials Institute, said that the Yangtze River-1000 engine that may be used in C919 in the future is being developed.

1. A major embodiment of the country's economic and scientific and technological strength.

The C919 medium-sized passenger aircraft is a landmark project for the construction of an innovative country, and the airframe has completely independent intellectual property rights. There are 155 seats in the basic mixed class, 169 seats in the all-economy class layout, 175 seats in the high-density layout, and a maximum capacity of 190 seats. The standard range is 4075 km, and the maximum range is 5555 km.

2. Broke the market monopoly of foreign aircraft giants.

The successful first flight of the C919 passenger aircraft will enable China's civil aviation to no longer rely on the import of Boeing and Airbus mid-level trunk airliners from Europe and the United States, break the monopoly of European and American aviation giants, and save a lot of foreign exchange for the country.

3. It contributes to the improvement of the country's military strength.

In the military aspect, the Y-20 is not suitable for conversion into a special aircraft due to its overly fat body and maximum take-off weight of 200 tons. The use of C919 to modify early warning aircraft, high-tech aircraft and other large military special aircraft has great potential.

Although the probability of the C919 being converted into a military fighter at this stage is very small, in the future, after China fully masters all the technology of the C919 and can achieve 100% localization, the possibility of the C919 to achieve dual-use is not impossible.

4. It can produce huge social benefits.

In terms of social benefits, the C919 aircraft project can drive the development of upstream and downstream industries, increase a large number of high-income jobs, and stimulate local economic development.

5. The market prospect is huge.

The C919 is China's first practical large passenger aircraft, and will also be China's first large passenger aircraft to be put into market operation and participate in market competition. From the perspective of strategic industries, this means that the fields of China's industrial upgrading have been further expanded from shipbuilding, high-speed rail, satellites, and nuclear power plants to "large passenger aircraft". As for the significance of the large passenger aircraft market, we only need to see the volume of the two passenger aircraft giants, Boeing and Airbus, to understand.

According to market estimates, in the next 20 years, the market space for C919-class single-aisle aircraft (equivalent to Boeing-737 or Airbus A320) will be about $850 billion, and the total space will reach trillions of dollars considering the cost of maintenance and upgrades. According to the calculations of COMAC (that is, the "mother's home" of C919), in the next 20 years, this market will need about 10,000 single-aisle passenger aircraft.

In China alone, nearly 7,000 passenger planes, worth nearly a trillion dollars, are expected to be needed over the next 20 years, of which about 4,500 are single-aisle jetliners. From a strategic point of view, as well as from an economic point of view, there should be a place for Chinese in this large and lucrative market. The significance of the first flight of C919 lies in the fact that China can share a large piece of the pie from the 1 trillion market.

This model is very popular abroad, and the aircraft uses a lot of advanced technology in the manufacturing process. Therefore, the aircraft is very stable during the flight, and the aircraft is equipped with an anti-collision system, which can fully protect the safety of passengers. So everyone was very happy after seeing the news of the successful first flight of this aircraft.

Many friends choose to take a plane when they go out. Because it is very convenient to do this, and it can also save a lot of travel time, in the process, you can also take a look at the country's great rivers and mountains. However, in the process of taking a plane, many people are more worried about their safety.

Therefore, you will find that many people will also buy an insurance for themselves when buying a plane ticket. In this process, the relevant personnel are also constantly developing new products. Therefore, many people have seen the news that the C919 aircraft made its first successful flight, and this model is very popular abroad.

This is because the aircraft is built using very advanced technology, and in the process you will find that the aircraft also has a lot of specific functions. The aircraft is also equipped with a collision avoidance system, which can also ensure the safety of passengers in the process. During the flight, the navigation performance is also very stable.

Therefore, this aircraft made in China is also very popular in the world. During the test flight, you will find that the cooperation between the engineer and the pilot is very tacit, and at the same time, a variety of different tasks have been completed. <>

So everyone was very happy after seeing the news, and the state and performance of the aircraft were very stable during the test flight. With the joint efforts of the relevant personnel, the aircraft will soon be able to complete the delivery work, so everyone can also wait patiently. After seeing the news of the successful test flight, it also means that the level of China's aviation industry has been greatly developed.

It can not only promote the stable development of China's economy, but also bring a happier life to the masses. If the aircraft can be exported, it can also bring a certain amount of economic income to the country.

It has indeed been welcomed by many people, this aircraft is particularly imposing, and the shape is also very distinctive, which has attracted the attention of many people.

The popularity of this model abroad is very high, and it is also very suitable, with a particularly large popularity.
