it means that AL-31FN engine shaft lubrication has been a serious shortage of air parking will be very is coming to. For example, CCTV reported the focus of Li Feng driving without power the F-10 made an emergency landing in deeds, Li Feng first received the alarm immediately after the engine began to turn down encores; in the process he was under the premise of maintaining the necessary flight altitude engine speed control 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,nike sportswear, the engine completely stop. 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,parajumpers homme, but is not limited by the funds to carry out test verification,http://115.29.36.128/forum.php?mod=viewthread&tid=1744373, measures to address the failure from the design principle can not be given. After all,air max mujer, the Russian people for the lubrication defect AL-31F series engines are two attitudes: I do not care so much about myself, improvise on the line; you want to improve,http://bbs.superdata.com.cn/home.php?mod=space&uid=53518&do=blog&quickforward=1&id=386403,louboutin soldes, acquire money. One of the key reasons for this one, is the reliability of the AL-31F on a single high-performance F-10 fighter aircraft such as more prominent,barbour, but the impact on the Su-27 platform has been far smaller.
2 tons),doudoune moncler homme,http://www.infocrystal.com/alink/apeboard_plus.cgi?command=read_message&msgnum=620/, high-speed,hogan online, high temperature (up to 260 degrees) of the state. Therefore,louboutin soldes, the lubricating oil for bearing lubrication system to lubricate the big pressure, high flow, reduce friction and reduce the temperature to remove heat,hollister online, has become the basis for the premise to protect the engine. Figure: turbofan engines need to rely on a combination of large and small rotating blade to the normal output power, rotation bearing support required Figure: damaged bearing components cut. In the absence of lubricating bearings running a heavy load, the contact surface will be destroyed into what? That is the answer.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,christian louboutin,http://bbs.wjrlt.com/home.php?mod=space&uid=69767, and even partial melting, 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,nike tn, is bearing the loss of rotational accuracy,woolrich roma,http://www.sujiaowuxing.com/home.php?mod=space&uid=145574, the final card cling shaft, the engine also bound to follow parking. In the more backward engine design, lubrication system reliability is not high is a common phenomenon. For example,barbour international, 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,http://cand.qee.jp/link_p/apeboard_plus.cgi?command=viewres&target/,toms online sale, accounting for 28% of lubrication failure. The AL-31F engine design is more complex due to the support,nike shox, for example,tn, it uses a dual-agency bearings,http://bbs.besbel.com/home.php?mod=space&uid=24670, four bearing low-pressure rotor design; bearing lubrication reliability has been very poor,veste moncler homme,http://www.88822.com/#03666/read.php?tid=980, 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,scarpe nike air force, it is tantamount to redesign the engine. Figure: Design of the lubrication system is followed by the support structure - or the entire basic structure of the engine design and determined to make a substantial change in the future is extremely difficult to determine the engine designIn 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.
