<p> the engine changes in a variety of overload, speed and intake air temperature under harsh conditions are in repeated violent change; the engine components subjected to stress cycles changeable several dozens of times to meet the design standards. For Su -27,piumini peuterey, AL-31F not only the failure rate is relatively low; and thanks to the double release innings,nike air max, even if one engine fails, there is still another engine for load balancing. This makes the AL-31F turn down even if there is, the development process is usually completely lost power is relatively slow; even air parking appears to rely on the possibility of the pilot is still a big single engine return. This is also the Russian people do not care about the AL-31F lubrication reliability of the defect cause - since they are not equipped to use their single-engine aircraft in the series engines. But the J-10 as a single machine, the load on the engine itself is formed above the twin machine must; and as stressed aircraft flying high agility, J-10 pilots to the frequency of operation of the engine.</p>
<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,air max pas cher chine, appears the second engine revolution drop alert; to 3.8 km, the engine completely stop. The exclusion of the accident has not yet concluded outside, since the development of the J-10 crash in all, except one is due to inter-cloud illusion caused the pilot,tn soldes, 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.</p>
<p> far beyond the expected AL-31F design And Su-27 compared to the J-10 platform, in addition to different single engine,air max pas cher pour femme, this late-type three generations of machines also abnormal emphasis on high agile flight. Content flying high agility are many, but popular explanation is that by allowing them to encourage pilots more brutal,christian louboutin pas cher, more wild, more violent extreme sexual manipulation, the maneuverability of the aircraft to the limit. For example,escarpins louboutin, in entry, exit large overload state aspect, high speed much greater agility aircraft - three generations of machines needed early 3-4 seconds to enter the limit maneuvering state from level flight,louboutin femme pas cher, or withdraw from the limit maneuvering state, and the high agile aircraft only need two seconds or less. F-14,tn pas cher, 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. This design of pneumatic control and structure of the aircraft have very demanding requirements. Presided over the J-10 flight test work weeks since the whole elaborate structure once during flight test work commented: "Like a sharp longitudinal step operation roll plus sharp braking is the most stringent test of aircraft structures." This evaluation is it does not apply to the engine,nobis femme, but it is in this context, AL-31F performance is substandard,barbour paris, especially in the J-10 platform. In the life of the standard engine, the time is actually a very loose standard, the real key is the use of strength. For example,soldes louboutin, large American F100 engine failure in service initially sudden outbreak that caused F-15 population lying nest, it is because the engine in actual use strength far exceeds the designers envisioned. F-15 pilots at high frequent maneuvers repeatedly push the throttle lever.</p>
<p> The AL-31F engine design is more complex due to the support, 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, 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>
<p> the engine suffered all Species unfavorable flight number and time much higher than the Su-27. Coupling these factors, so that AL-31FN engine J-10 platform on conditions encountered far more severe than the Su-27.</p>
<p> 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,abercrombie paris, improvise on the line; you want to improve,air max, acquire money. One of the key reasons for this one,tn air max 2014 pas cher, is the reliability of the AL-31F on a high-performance single-engine J-10 fighter so prominent,nike tn, but the impact on the Su-27 platform has been far smaller. Data Figure: March 31, 2013, the Air Force Su-27 fighter plane in flight training accident in Rongcheng City, Shandong Province,hogan uomo, Shan mayor will head north east port bridge 200 meters a beach,air max pas cher, two pilots unfortunate death, without causing collateral damage ground.Three: J-10 engine brought demanding.</p>
