 but the share of market segments Growth of demand for the largest models.Yellow white heart: is independently developed it?C919 model project developed position is "independent research, international cooperation,hogan saldi, international standards." Some people have questioned the domestic C919 is "yellow white heart",scarpe hogan scontate, said China only their own design drawings and made a chassis, airborne critical systems including engines,scarpe hogan, avionics systems are the procurement of other countries, and concluded: obviously It assembled goods and touted as independent research, and Y-8,hogan rebel uomo, Y-10 compared to no be proud of.We start with the "shell." The body including the nose, fuselage, wings and tail of several parts, including the British aircraft wing components manufacturer called "aircraft soul".

 especially the large aircraft,hogan scarpe uomo outlet, it is about the honor of a nation. Boeing's former chief executive,hogan donna, said:. "I do not think China has insurmountable technical obstacles, they have twice sent astronauts into space, and some of the world best aerodynamicists is the Chinese people," This aircraft will It is a more ambitious story.In this way, C919 leave in the voices of doubt. Although information from the China Commercial Aircraft showed their determination to become a major world's third largest civil aircraft manufacturer, named C919 can be seen from Airbus and Boeing to work together to become the world aircraft market ABC will,hogan bambini, Airbus English letter "A "Heading (Airbus),scarpe hogan uomo roma, Boeing is" B "(Boeing),hogan donna outlet," C "from China (China) and manufacturer (COMAC) first letter in English. However, objectively speaking, C919 is China following the Y-10 after the second paragraph of self-designed large civil aircraft, aircraft manufacturing industry on the global civil aviation is concerned, not fill the medium and narrow-body aircraft research and development gaps.

 while the use of composite wing - Titanium accounted for about 10% ,hogan scarpe, while competitive models (B737 and A3200) accounted for far less than C919. C919 from the nose, wings to the tail,hogan, the engine,hogan junior, the design is painstaking.2006 21st Century Business Herald reporter specializing visit Boeing, Boeing Commercial Airplanes vice president Carolyn Covey said: Boeing aircraft parts in about 65% of all purchases outside of the Boeing 777 or 767 The entire aircraft fuselage is manufactured at different factories in Japan, and some engines are made in France,hogan, most of the flight control, leading edge devices, electrical and hydraulic systems are produced in North America. This is the moment the aircraft manufacturer mainstream "main manufacturer - supply mode" in order to develop cost and risk-sharing projects.She also told the 21st Century Business Herald reporter,hogan rebel, one complete Boeing 747 aircraft, to be a combination of 4.5 million parts tightly together, the various components at the same time, from around the world collected together and makes up the aircraft, which is more than make it more difficult to fly aircraft. If people can buy the parts to assemble and make it fly, would not the world's only two manufacturers of large aircraft. In particular, she stressed that: Boeing core competence is what? That we have the ability to integrate, including the technology, design and innovation blend 'main supply mode ",hogan interactive, this is difficult to imitate Boeing have but others can not copy something.China Commercial Aircraft also adopted the "main supply mode" Objectively speaking.

 it is the decision of the wing of an airplane take-off weight of the aircraft, the aircraft operator efficiency and economy. If you have previously Airbus rival Boeing in terms of the production of commercial aircraft wing it is Russia and Japan, then China is now catching up.C919 deputy chief designer of China Commercial Aircraft Technology Standing Committee Chen Yingchun, said: the decision of the two decisive factors in aircraft performance is the aerodynamic lift to drag ratio (aerodynamic efficiency) and the weight of the aircraft, at the design stage our goal is to C919 machine weight wing Boeing to go beyond the level of aerodynamic efficiency and to reach the level of Airbus. From China's top aircraft pneumatic professional team of 100 experts,hogan uomo, were designed for the C919 500 airfoil, currently used on C919-101 wing is the result of several rounds of structural testing selecting the best representatives of a number of countries in Europe The wind tunnel test results were highly praised by the international counterparts, the acoustic impedance ratio,hogan rebel, look for flight characteristics, stall characteristics of several important indicators beyond competitive models. (See Chart 2)To reduce weight to reduce fuel consumption,hogan scarpe, C919 used 600 parts in composite materials and aluminum lithium alloys, composite materials used in an amount of 20% by weight of the aircraft structure.
