<p> CCTV reported the focus of Li Feng driving unpowered landing deeds in the J-10, Li Feng first received the alarm immediately after the engine began to turn down encores; in the process he was kept at the premise of the necessary flight altitude of the engine speed to a minimum, in order to delay the engine air parking. When six kilometers from the airport, appears the second engine revolution drop alert; to 3.8 km,2014 hogan scarpe italia, the engine completely stop. The exclusion of the accident has not yet concluded outside,http://211.86.128.2/gjjl/Review.asp?NewsID=595, since the development of the J-10 crash in all, except one is due to inter-cloud illusion caused the pilot, the whole issue is caused due to the engine. According to the Navy engine professional publications, has repeatedly consulting our design and production units in Russia on lubrication defects AL-31F series engine. The Russian side said that they carried out to improve the design, but is not limited by the funds to carry out test verification, measures to address the failure from the design principle can not be given. After all, the Russian people for the lubrication defect AL-31F series engines are two attitudes: I do not care so much about myself,hollister milano, improvise on the line; you want to improve, acquire money. One of the key reasons for this one, is the reliability of the AL-31F on a high-performance single-engine J-10 fighter so prominent,hogan junior,http://usr.cc/home.php?mod=spacecp&ac=blog&blogid=, but the impact on the Su-27 platform has been far smaller. Data Figure: March 31, 2013,hogan sito ufficiale, the Air Force Su-27 fighter plane in flight training accident in Rongcheng City, Shandong Province, Shan mayor will head north east port bridge 200 meters a beach,hogan baby, two pilots unfortunate death,scarpe hogan outlet,http://www.xmarks.com/s/site/www.tadayumi.sakura.ne.jp/apeboard_plus.cgi/uopingcha/, without causing collateral damage ground.Three: J-10 engine brought demanding,scarpe uomo hogan, far beyond the expected AL-31F design And Su-27 compared to the J-10 platform, in addition to different single engine, this late-type three generations of machines also abnormal emphasis on high agile flight. Content flying high agility are many.</p>
<p> but popular explanation is that by allowing them to encourage pilots more brutal,http://www.ezjlh.com/forum/showtopic-78275.aspx, more wild, more violent extreme sexual manipulation,hogan, the maneuverability of the aircraft to the limit. For example, in entry,hogan donna, exit large overload state aspect,http://fy529.com/forum.php?mod=viewthread&tid=1879784&fromuid=77051, high speed much greater agility aircraft - three generations of machines needed early 3-4 seconds to enter the limit maneuvering state from level flight,scarpe hogan outlet, or withdraw from the limit maneuvering state, and the high agile aircraft only need two seconds or less. F-14, F-15, Su-27 earlier this three generations of machines roll performance than the poor, while the aircraft design specifications such as the J-10 is not only to reach the maximum rolling speed of 270 to 300 degrees / sec such human resistance that limit; and with particular emphasis on the ability to reach maximum rolling speed and abrupt exit in the shortest possible time.</p>
<p> the fighter on the use of Russian-made engines.In fact, although the presence of these defects, but mainly about the performance and impact indicators; include engine thrust size, lifetime, and so the overall weight of the engine. AL-31F family maximum reliability bottleneck from its support structure and lubrication system design based on this deployment. Turbofan engine rotating components acting as a gas turbine rely on its core moving parts include a fan, low pressure compressor,outlet bologna woolrich, high pressure compressor, turbine are mounted on a rotor; the rotor itself should be passed to the entire engine load box,http://dsechemistry.com/bbs/forum.php?mod=viewthread&tid=2722505&fromuid=256935, it support structure and the bearing to achieve through. During operation of the turbofan engine,hogan spaccio, supporting high-speed rotation of the rotor bearing has been in a heavy load (equivalent to 7 to 9.2 tons), high-speed, high temperature (up to 260 degrees) of the state. So much pressure on the bearings are lubricated.</p>
<p> high flow, reduce friction and remove heat to reduce the temperature of the engine becomes the basis for protection work premise. Once the bearing without adequate lubrication, rotational resistance rapidly increase the temperature rises rapidly; local frictional heat will appear microscopic friction surface deformation and friction welding, and even partial melting,http://www.clarityenglish.com/englishonline/index.php?item/create_form/1,woolrich prezzi, and these small joints It will be followed in the rotation of the tear. Adhesion between the bearing parts - tear - sticking to the last cycle of development, is bearing the loss of rotational accuracy,http://www.cxdby.net/home.php?mod=space&uid=76392, the final card cling shaft,hogan on line, the engine also bound to follow parking. In the more backward engine design,scarpe hogan online, lubrication system reliability is not high is a common phenomenon. For example,hogan scarpe donna outlet online, in 1985 the army of the engine air parking accidents, accidents caused by engine lubrication system failure accounted for 43%. US TF34 engine accident occurred 90 times in 1983, accounting for 28% of lubrication failure. The AL-31F engine design is more complex due to the support,outlet hogan online italia, for example, it uses a dual-agency bearings, four bearing low-pressure rotor design; bearing lubrication reliability has been very poor, while over the same period RD33 engines such problems are rare. To solve the problem of lubrication reliability AL-31F's very difficult, because completely changed the design of the support,hogan scarpe uomo 2014, it is tantamount to redesign the engine. In the design of the AL-31F engine lubrication system pressure drop is too low turn after protection operation; therefore turn once the engine down alarm occurs, it means that AL-31FN engine shaft lubrication has been a serious shortage of air parking will be very is coming to. For example.</p>
