China can be seen from the two graphs so terrible: actually uei jobs Tags: transportation of lithium batteries large aircraft Category: ho-Gazette
Local time at 8:40 on January 16 Xu, over Japan Takamatsu Airport, a large plane dropped a rickety. The aircraft performed ANA Flight 692, this by Yamaguchi Ube Airport uei jobs to Tokyo Haneda Airport, but at 8:45 whipped whipped brain falls head Takamatsu Airport. According to ANA said, this is a Boeing 787 Dreamliner. Flight uei jobs made an emergency landing because of the cabin smoke, uei jobs the incident was a total of 129 passengers on board and eight crew members, a total of 137 people. After the flight made an emergency landing, safely evacuated 137 per capita, of which five people were slightly injured. This is the seventh accident Boeing 787 Dreamliner uei jobs occurred within 10 days. From the probabilistic analysis, such aircraft, is not suitable for flying. In less than 24 hours after ANA Flight 692 made an emergency landing, the Federal Aviation Administration issued an emergency airworthiness directive - Boeing 787 Dreamliner require US users to temporarily stop the type of aircraft operations, and other regulatory agencies to follow up on the recommendations. This means that United Airlines grounded six of the model aircraft. Boeing chairman, president and CEO Jim McNerney (Jim McNerney) uei jobs immediately issued a statement that "provides all the resources offered by the company, assist uei jobs in the investigation." McNerney while apologize. Around the world have heard about the Boeing 787 "off notice" - ANA 17, grounded; Japan Airlines 7, grounded; Air India 6, grounded; Chilean National Aeronautics 3, grounded. In addition, to maintain uei jobs 5 787 Qatar Airways and retain two Polish Airlines announced - cancel some flights, then are all grounded. The last statement is Ethiopian Airlines, Africa's only 4 787 announced grounded. Until January 17, the world's 50 Boeing 787 aircraft parked on the ground all. As for when to resume flying, US Transportation Secretary Ray LaHood, said on January 18, in the aviation security sector "to one thousand percent sure" before the Boeing 787 Dreamliner safety, the aircraft will not be missed, The specific date of the missed unpredictable. The Boeing 787 Dreamliner, the Boeing and Airbus A380 "showdown" flagship uei jobs product, even if a big rookie, in Xiecai state, which in the end is how it happened?
The global production is the first one hundred of the 787 Dreamliner final assembly of the big day, but a chain of accidents occur, so that Boeing feels frustrated. In fact, the Boeing 787 since September 2011 delivery, uei jobs the accident has been continued. Cockpit glass cracks, battery fire, fuel leak, brake failure ?? In most aviation industry analysts as well as aircraft manufacturing experts, this is just the new aircraft in service, uei jobs running normal uei jobs performance period. For example, Chinese manufacturers who fly deputy chief of Zhou Jisheng ARJ21 aircraft to reporters, said: "On the one hand, just put into use new aircraft malfunction is a natural law, in the early life of the new aircraft and the end of life, are the high incidence of failure on the early life of the aircraft are generally required to go through a fault running, uei jobs running-in period accounts for 5% to 10% of the entire service life of the aircraft. 787 in September 2011 to complete the world's first aircraft delivery is currently in the early life of failure-prone, With the increasing uei jobs use of time, the failure rate will gradually decline. "" Xinmin Weekly "from the former chief architect of China Commercial Aircraft 吴兴世 Department learned that the 787 production, uei jobs using the typical" main Manufacturer Supplier "mode, that is, as the main manufacturer Boeing, the global tender, the successful bidder qualified suppliers, which provide parts for aircraft. Our AVIC Shenyang Aircraft Civil Aircraft Company in September 2012 news release, the company to Boeing delivered uei jobs the first 100 Boeing 787 tail and wingtip leading edge products. It is reported that SAC is the world's only supplier of the 787 vertical tail and wingtip leading edge projects. Of course, the accident before 7 January 16 Boeing 787 Dreamliner occurred, have nothing to do with SAC participating components. Boeing on the 787 Dreamliner model, not only with the "main manufacturer supplier" mode, but also architecture leverages supplier of advanced database systems and management systems around the world and keep in close contact, designed to achieve 24 hours. Its use of the time difference around the world to achieve continuous process operation, which greatly enhance efficiency. uei jobs The idea is indeed the beginning of the operation, such as Boeing's vision, making 787 became the fastest conversion from paper to production processes models, but in the manufacturing sector, the supplier will be a series of problems emerged. For example, partners around the world from where the collection of components to assembly plants, often the problem of excessive size of the error, resulting in the case of the various parts of the body can not be joined to appear. Similar problems have plagued the project to promote the 787, for which Boeing began to learn from their mistakes, and gradually "close right." For example, the acquisition of a stake in Alitalia manufacturer Alenia North America uei jobs in 2009, is considered to be increased in order to strengthen control over 787 parts supply initiatives. Alenia and parts suppliers in the problems the industry is also considered one of the important reasons for poor progress in 787 projects. In fact Boeing uei jobs 787 have been reflecting on the outsourcing project was a bit too much lead to project out of control, the former president of Boeing China Wang, once saying: "Despite the need for more global partners in the manufacture of new aircraft, but how the division of labor in this issue on will reconsider. "
Vice president of the Boeing 787 Dreamliner crux unknown and chief project engineer Mike Sonnett (Mike Sinnett) boasted that the reliability of the Boeing 787 and the company first introduced 777 new products at the same level, he hundredth one hundred assured safe flight 787, you can still questioned 787 experts design flaw. Chairman of the famous aviation experts uei jobs and Boyd (Boyd) uei jobs Aeronautical Systems Research Center, Michael Boyd (Michael Boyd) in an interview uei jobs on CNBC, directed Boeing: "If the lead to make the FAA grounded all 787 battery problem airliner decision, finally proved to be a 'design flaw', Boeing may fall into a lot of trouble, "Boyd next, it seems alarmist:." Now the situation 40 years ago, and whether uei jobs 747 similar situations it? when the new models listed have encountered a big problem, and finally have been solved, or is another extreme example, Lockheed Electra, in fact, lead to the failure of this model Lockheed Germany completely out of the passenger aircraft market! "The problem happened before the Boeing 787, not only in the battery, you can say that the accident were exposed to a variety of problems. Aerospace and defense sector Citigroup analyst Jason Gursky (Jason Gursky) analysis on CNBC television program: "If this is a problem of the manufacturing sector, uei jobs we are able to quickly uei jobs solve the problem if it is a design, You may need more time, but the overall outlook for this aircraft in the short term there will be more damage, "Michael Boyd final judgment, he may not be set up alarmist:" I do not think that would be another 787 an Electra, but if this is really uei jobs a problem of aircraft, Boeing will spend a lot of money, or even the source of future uei jobs losses for years. "Jason uei jobs Gursky recommend holding Boeing stock investment in the program people continue to hold, he said, airlines and customers in the Dreamliner have large investments, "the next month, I think we'll see a good chance for admission Boeing shares." In fact, Mike Sonnett 787 does not adhere to the design problem, not without reason. Sonnett While acknowledging Boeing is working with clients and regulatory agencies at the same time improving the reliability of the 787 active duty, also said that the reason Qatar Airways electronic equipment problems occurred in December 2012 has surfaced uei jobs - United Technologies Corporation's uei jobs aviation potentially problematic electrical uei jobs panel production subsidiary in a number of electronic circuit boards. For 787 ANA fault January 16, the preliminary analysis of the considered battery uei jobs problem concerned, this is not 787 lithium-ion battery for the first time a failure occurs. Some experts believe that, compared with previous models, the 787 higher dependence on electricity, uei jobs so the battery on going higher than previous models, which may be the performance of the battery as well as the stability of higher uei jobs Claim. As the Boeing 787's battery supplier Yuasa Corporation (GS Yuasa), founded in 1918, is one of the five battery manufacturers in Japan, long battery research, development and production. Yuasa 787 provides for the nominal voltage of 3.7 volts, the model for "LVP10", "LVP65" lithium-ion battery. Yuasa company claims that they produce battery first sent to France Thales Group (France's Thales Group), assembled and then sent to Boeing, it is not necessarily conclude that the failure to appear in their company's batteries. Japan's transport ministry uei jobs and the US Federal Aviation Administration began 21 Boeing 787 aircraft battery suppliers uei jobs in Japan Yuasa investigation.
China is a large subscriber revelation China Boeing uei jobs 787 Dreamliner, currently China's major airlines Boeing 787 orders for about 41, located in Air China, China Southern Airlines, Hainan Airlines, Xiamen Airlines and other companies, but has failed to deliver. Investment Advisor in the transportation industry researcher uei jobs Cai Jianming believes that this may be 787 in China has not yet received official approval concerning flight. There are also direct disclosure media, 787 in China failed to deliver reasons, mainly uei jobs that of the 787 were still in China CAAC airworthiness certification work, and that work had been completed and the granting uei jobs operating licenses, but because the 787 extension Prior to the delivery of documents which led to expire, so the program had to go again. Chen Feng, chairman of Hainan Airlines, said the company even consider, give up the dream of the 787 models, but shorter journey time to change the model of Boeing's 747-8 larger uei jobs aircraft. Airworthiness certification, but in reality is put into commercial aircraft uei jobs could fly a mark. Japan's Mitsubishi Heavy Industries MRJ regional jet development, on account of airworthiness certification issue, once again delayed until the end of 2013; Russia "Superjet" SSJ-100 regional aircraft is at the May 2012 demonstration flight, crashed into Salak mountain crashed. There is concern - China Commercial Aircraft being developed and made large aircraft C919 ongoing trials validated ARJ21 regional uei jobs jet aircraft, has been questioned about the progress and the project itself. (Contained uei jobs "Xinmin Weekly" 2013 Section 4) United Airlines Boeing 787 in late 2012 led to failure of the generator and the power distribution panel, and Hamilton Sundstrand (Hamilton Sundstrand) uei jobs related. Hamilton Sundstrand is not only Boeing's uei jobs partner, is one of China's major suppliers of commercial flying. November 16, 2010, "China Aviation News," said Hamilton Sundstrand to provide electricity for ARJ21, the main switchboard and the ram air turbine emergency power system; auxiliary power systems, including the APS2600 Auxiliary Power Unit; high lift drive system, including flap and slat drives, drive chain, power-driven components and controllers; and fire detection and suppression systems, including engine / auxiliary power unit fire detectors and fire extinguishers, smoke detectors and toilet tanks and fire extinguishers, trash can with a hand-held fire extinguishers and cabin fire extinguishers. uei jobs Hamilton Sundstrand for the ARJ21 various systems provided during the entire life of the program will generate $ 1.2 billion in revenue. China Commercial Aircraft Select Hamilton Sundstrand for the C919 offers a variety of systems, including power generation systems, primary and secondary power distribution system, ram air turbine emergency power system, the pilot control device (including the side stick, rudder pedal brakes, gear control lever plate The control panel and thrust console) and so on. 787 issues uei jobs facing Implications for China-made large aircraft, uei jobs but also in the time window for commercial aircraft listing. In fact, the 787 is Boeing and Airbus compete in a model 380, Boeing 787 and Airbus A380 aviation uei jobs markets represent two different future direction. A380 represents the idea - the future role of large-scale growing aviation uei jobs hub, the airline scheduled flights between uei jobs hubs various convergence conducive to the effective allocation of resources. Requiring larger aircraft during flight hub, this concept was designed based on the large-scale A380. 787 represents the idea that the future of air travelers do not like getting frequent uei jobs transit hub, hoping to achieve no direct transfer between second-tier cities, and therefore requires a capacity not too much, but the journey is long enough performance good enough aircraft. Airbus for 787, developed A350XWB models, and has completed the assembly, so that aviation enterprises have a new object in model selection. (Contained "Xinmin Weekly" 725)
