<p> diameter shortened by 48%, greatly reducing the frontal area and drag, thrust-weight ratio and therefore higher than the turbojet -5 more. Our second generation of engines with turbojet and turbofan 7 -9 representative. -7 Turbojet engine which is technical information P- �-300 engines manufactured by the former Soviet Union provided, mainly for the F-7 aircraft. 7 turbojet engine performance than the turbojet 6 has been greatly improved, the maximum thrust of 38.2 kN afterburning thrust of 55.9 kN, respectively, compared with turbojet 6 increased by 50% and 77%. 1965 to complete the development.</p>

<p> the US EP-3 reconnaissance plane is the use of F-8 characteristics of a short life, and from the former constantly harass,scarpe hogan donna, cause I want to keep the F-8 aircraft to replace the aircraft, to monitor the pressure pole Big. Bottleneck engine has been plagued China, in order to catch up with the world advanced level. To meet the needs of the third-generation fighter, China turbofan -10 project began to be launched, the final completion of the design and development,hogan donna, to achieve the purpose of the thrust-7 and above, to catch up with developed countries,hogan uomo, the level of the mid-1980s, and a lot of equipment in the annihilation - 10, above -11, to some extent, eliminate the country has been relying on imported engine dilemma. Weight ratio / power weight ratio, fuel consumption, service life is a major indicator of the engine, which determines the important parameters of payload, range and economic applicability of the aircraft. And in addition,hogan interactive donna, the surge boundary and flame border is also very important, which determines flight safety and accident rate, while China is the engine in these areas have not yet reached the advanced standards of developed countries. Chinese engine technology and sent to the country in 30 years, the gap is a reasonable estimate,hogan uomo, engine covers theory, materials, processing,hogan rebel outlet, design and other basic industries,hogan prezzi, unable to form an instant beyond. Only steady at every step to make up classes, every five years to catch up with 25-year plan to develop China's industrial sector is sound science. Currently turbofan turbofan -15 and -20 projects have been launched,scarpe hogan, but people should not be too demanding for the industrial sector, the Great Leap Forward thinking often make things worse.

<p> mass production in 1966. Blue empty F-11 fighter fleet off battle F-8FTurbofan -9 complete imitation is carried out, and after realized that the future must be equipped with turbofan aircraft engine,hogan outlet online, China's introduction of the margins of Soviet hegemony British Spey engine according to the British exports to China of Spey engine, "Spey "MK202 type is a British Rolls - Royce in the mid-1960s developed turbofan engine, long 5025 mm, 1093 mm in diameter and weighs 1,hogan scarpe,850 kg, the maximum thrust of 54.5 kN 91.1 kN afterburning thrust,outlet hogan scarpe uomo, thrust- ratio of 5.05,hogan online, the largest military fuel consumption 0.0684 kg / cow per hour,hogan junior, maximum afterburner fuel consumption 0.2 kg / cow per hour, bypass ratio 0.62. With advanced level in the world at that time, the 1960s was introduced into China for imitation,hogan donna, culminating in 2003 became a complete success of China's Qinling engine, which is turbofan -9. Turbofan -9 in the final equipment on the JH-7 Flying Leopard,hogan italia, make Feibao became a combat radius of more than 1000 kilometers, it can be used with most of the fighter planes in combat bombing missions. These engines are taking our generic route,hogan scarpe, my country has no independent research and development capacity of the engine until the turbojet and turbofan -13 -10 appear. Turbojet -13 -7 on the basis of transformation from turbojet, renovation life expectancy of 300 hours, to reach 43.1 kN thrust,hogan rebel, afterburning thrust of 64.7 kN is reached, respectively, compared with WP7 increased by 50% and 15%, greatly improving the surge margin. 13 turbojet engine development work began in full swing from 1978, 1980, the first three engines start debugging test, flight 1985 installed,hogan on line, final assembly of the F-8 on the aircraft. People's Liberation Army Flying Leopard fighter competitionThese engines and the international advanced level compared to the relatively large gap still, even the most advanced turbojet -13 Anglo also a huge gap. 2001 Sino-US South China Sea collision incident.</p>
