Boeing 787 Dreamliner Battery Problems
In 2013, the second year of service for the Boeing 787 Dreamliner, a widebody jet airliner, several aircraft suffered from electrical system problems stemming from its lithium-ion batteries. Incidents included an electrical fire aboard an All Nippon Airways 787 and a similar fire found by maintenance workers on a parked Japan Airlines 787 at Boston's Logan International Airport. The United States Federal Aviation Administration (FAA) ordered a review into the design and manufacture of the Boeing 787 Dreamliner, followed by a full grounding of the entire Boeing 787 fleet, the first such grounding since that of the McDonnell Douglas DC-10 in 1979. The plane has had two major battery thermal runaway events in 52,000 flight hours, which was substantially less than the 10 million flight hours predicted by Boeing, neither of which were contained safely. The National Transportation Safety Board (NTSB) released a report on December 1, 2014, and assigned blame to several groups: * GS ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Lithium Iron Phosphate Battery
The lithium iron phosphate battery (LFP (lithium ferro-phosphate), or Li-IP) is a type of lithium-ion battery using lithium iron phosphate () as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of Q1 2021, LFP type battery market share reached 24.1%, with Chinese manufacturers holding a near monopoly, and is expected to rise further to surpass NMC type batteries in 2028. The energy density of an LFP battery is lower than that of other common lithium ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA), and also has a lower operating voltage; CATL's LFP batteries are currently at 125 watt hours (Wh) per kg, up to possibly 160 Wh/kg with improved packing techn ...

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Airworthiness Directive
An emergency Airworthiness Directive (EAD) is an airworthiness directive issued when an unsafe condition exists that requires immediate action by an aircraft owner or operator. EADs are published by a responsible authorities such as FOCA, EASA or FAA related to airworthiness and maintenance of aircraft and aircraft parts. It contains measures which must be accomplished and the related periods to preserve their airworthiness. Technical information is addressed to operators and maintenance organisations of affected aircraft only. EADs become effective upon receipt of notification. Notable incidents that have led to emergency airworthiness directives * On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC-10 crashed after takeoff from Chicago O'Hare Airport. An engine separated from the plane, damaging electrical and hydraulic systems, causing the left wing's slats to retract and stall that wing. This led to the type being grounded in June 1979. *On August 20, 2007, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
