The concept of large aircraft

Large aircraft generally refers to the total take off weight of more than 100 tons of transport aircraft, including military, civilian large transport aircraft, but also above the level of the Route 150 aircraft. The world only the United States, Europe and Russia has the ability to manufacture large aircraft, while the occupation of the international routes, only the United States civil aircraft market, Boeing and Airbus in Europe. China's development of large aircraft can be described as twists and turns. As early as age 70 in the last century, ou
r country has to start big plane "brought 10" of the development, but due to various reasons, eventually dismount in 1985.

China's large aircraft research, the market with two hands

As the international civil aircraft market is enormous and the competition fierce. At present, China has become the world's second largest civil aviation market in the next 20 years alone, the domestic aviation market will need 3,000 new planes, about 390 billion U.S. dollars of the market space. Among them, the upper and lower single channel 150 aircraft will account for Qi Cheng. International Route civil aircraft market is currently almost entirely Boeing and Airbus have been monopolized by two companies, China's large aircraft in the aviation market in order to occupy a place, they must face the fierce market competition. China's large aircraft achieved first flight in 2014, 2016 commercial. To achieve commercially available, there should be market awareness.

The so called market awareness is the need for cost conscious and brand awareness. The value of China's manufacturing industry figures LAW 100 hui, large aircraft manufacturing in the industrialized mass production, we must comply with the requirements of mass production, there must be cost consciousness and efficiency awareness. According to market analysis, China's large aircraft C919 fuel consumption than the current 15% lower than similar aircraft. The future, is published with the letter C at the beginning of China's large aircraft, performance, and price will certainly be better than the Boeing 737 and Airbus 320. R & D production and marketing strategy has already been synchronized so that Chinese companies have made fly's initial market returns. Maiden flight at the end of last year success of regional aircraft ARJ21 700, has gained 208 orders. As long as we stick with Chinese characteristics, reflecting technological advances of civil aircraft development, adheres to R & D and market both hands, the future, China will be able to fly large aircraft, blue sky, and will bear fruit in the international aviation market.

Developing large aircraft, the engine of China's industrial upgrading

Large passenger aircraft is the world's most complex and high tech products, known as "flower of Industry", Optical components alone 3000000 6000000 much. And because the safety of civil aircraft, durability requirements are much higher than cars, trains and other civilian products, the operational life of up to tens of thousands of hours, as long as several decades, so the materials, electronics, equipment, and metallurgical industries in the upstream demand is very high, by engaging in large aircraft, is bound to raise a country's overall strength, promote industrial upgrading, promote scientific and technological progress, the formation of new economic growth point and so on greater significance.

China's industry is characterized by a complete range, seem to require large aircraft can provide complementary products internally, but the overall strength of basic industries because of the restrictions, coupled with civil aircraft to satisfy the airworthiness requirements, so really for large aircraft supporting ready made products is very limited. For example, China has now completed its first flight of the regional jet ARJ21 700, in the engine, electronic control systems and other key components, because the domestic product is temporarily not meet the technical requirements, so the localization rate is very low.

China's future large aircraft targets is to achieve 30% localization rate, which for domestic materials, electronics, airborne equipment, processing and manufacturing, and other related industries made an urgent upgrade requirements. Therefore, the development of large aircraft is undoubtedly one of the best engine for promoting China's industrial upgrading. Zhang Qingwei that industrial upgrading all these years we have been mentioning, but if you do not have a large aircraft such as the national project driven, due to a lack of clear direction, often very slow speed. On the contrary, if the project has led to upgrade the traditional industries have a specific targets and standards. For example, it appears inconspicuous machine chair coat, carpet and other textiles, to be used for civil aircraft must have fire resistant, which made the traditional textile industry upgrade.

Large aircraft project led groups of breakthroughs in key technologies

Large Aircraft project involves fluid mechanics, solid mechanics, computational mathematics, thermal physics, chemistry, information science, environmental science and many other basic disciplines, through the large aircraft, such a major science and technology projects driven by these basic disciplines of the development will be greatly accelerated. At the same time, because the big planes are modern high tech, highly integrated, driven by large aircraft development is also related to science and technology breakthroughs in key technology groups.

Development of large aircraft to carry out less than a year, has launched a number of key technologies and has a number of key technology breakthroughs. For example, in our low speed aerodynamic research is very difficult to test technology: turbo fan dynamic simulation technology has been successful. The success of this test technique, so that our country has joined the United States, the European Union after the first in the world to have mastered the technology of the pilot countries.
