The author:(作者)aaapublished in(发表于) 2014/9/20 11:57:26 Domestically produced large Jet C919 to enter the total still exceed the 3 mark
19th, China's COMAC C919 large passenger plane developed fully into the structure of the final assembly stage, involution of the fuselage in the forward fuselage and kicked off final Assembly began. Is the forward fuselage of the first docking with the fuselage body, other parts will be delivered in two months and shipped to Shanghai for final assembly.
Body docking marks the beginning Assembly
Striving for flight in 2015
C919 Jumbo body construction with a total length of 38.9 meters wingspan 35.8 meters, consists of head, the former in the fuselage, fuselage, Center wing, aft fuselage, rear fuselage behind the front and rear sections, vertical tail, flat-tailed nine segments and associated parts, docking is the final Assembly of the fuselage in the forward fuselage and a first step.
Currently, by in the airlines industrial into fly, and wrote, and West fly, and Shen fly, and hafei, and space special material and the process technology Institute and Zhejiang West aviation industrial limited, units manufacturing of first frame machine Qian fuselage, and in the fuselage, and central wing, and in the Hou fuselage, and Deputy wing has through China Civil Aviation Council of airworthiness check, arrived Shanghai delivered, other Department segment and parts will in two months within gradually entered Assembly.
C919 jumbo jet was developed into the "deep end" iron bird testing, testing and airworthiness of avionics system and other related work is being synchronized, and strive to complete by the end of the first body structure and docking work, 2015 will go airborne systems installation and integration challenges, such as greater development, strive to the end of 2015 to achieve flight.
China's C919 commercial aircraft final assembly manufacturing center will become the incubator. Construction began in May 2011, and is now in use by 2020 will have 150 of the C919 large passenger aircraft and 50 years of ARJ21-700 aircraft mass production capability.
GA is not a simple DIY
Integrates breakthrough three mark
In the era of global sourcing, and none of the aircraft manufacturer making all components, Boeing and Airbus, but also through global sourcing enables integrated Assembly. C919 is also their design, final Assembly, for global procurement. Deputy designer of the C919 Zhou Liangdao said: "the General Assembly is not a simple DIY to do systems integration, improve the performance of the aircraft needs to break the third mark. ”
First pass is designed, the C919 to what performance, meet the requirements under what conditions flights, how the standards of safety, economy and comfort ... ... These are aircraft designers needed to complete the work. C919 is the first Chinese-designed large passenger aircraft.
Second is to break down, the aircraft's overall requirements needs to be decomposed into every part, that requires every component to meet the technical requirements in accordance with this request finding suppliers and ensure that suppliers are required to provide the product, at the same time, you also need to control the production of parts suppliers.
Three conditions are integrated, or C919 to enter the final assembly stage. Best engine does not necessarily make for the best aircraft, this is because the aircraft as a whole, to improve the performance to achieve the best match. Integration is the key to finding problems, and lowest cost solution in order to achieve the expected performance of the aircraft.
