Strategic Study of CAE 2013, Volume 15, Issue 11, Pages 67-73
Design,manufacture and maintenance of military fighter engine are particularly a lot more difficult to learn than those of other military aero-engines. Owing to military aero-engine is monopolized by very few countries and its core technology is never transferred, it features high risk,high investment,high barrier and high cost. Currently,design and manufacture of military aero-engine in China have not reached the level of independent research and development,instead,the method of long-term dependence on copying or importing others' military engine is adopted to meet the needs. However,after over twenty years of unremitting efforts of some domestic enterprise,Chinese all fighter engines including engines powered in designing aircraft have completely achieved the level of independent maintenance,whose maintenance technology, ability,quality, efficiency and cost have reached or surpassed those of importing nations,with a change developing from nothing and an improvement from weak to strong. In particular, more than ten projects concerning research and development of remanufacturing technology and the engineering application with the feature of independent intellectual property rights have promoted leapfrog improvement of Chinese military aero-engine independent maintenance level,whose function cannot be substituted.

Strategic Study of CAE 1999, Volume 1, Issue 2, Pages 24-29
It has been only 50 years since gas turbine engines arrived in the early 40´s, however, there have been great changes in gas turbine technology progress. Gas turbine engines has been playing an important role in the development of aviation industries.Turbofan engines are always at the leading edge in technical area. It has become the major power for modern fighter aircraft and transportation aircraft in the trunk airlines. Thrust-weight ratio, one of the most important technical parameters of fighter aircraft engine, has been improved from 2 in the early time to 8, while the fuel consumption has been reduced from 1.0 kg/daN ▪h to 0. 6～0.7 kg/daN▪h.
From late 40´s to the early of 21st century, there have been four generation replacements of fighter aircraft. Fighter aircraft engine with a thrust-weight ratio of 8 was emerged in early 7O´s. It remains the main model on active service for developed countries today, and is still under development.Fighter aircraft engine with a thrust-weight ratio of 10 is in development, and hopefully will be put into service by 2003. Aeronautically developed countries have been applying their aeroengine research and development program since 80´s, in order to provide themselves with military and commercial advantages.The target is to demonstrate engine technologies of a thrust-weight ratio of 15〜20 and a fuel consumption reduction of 30%〜40% . It is forecasted that this type of engine shall be successfully developed by the year of 2020, which double the engine capability. It shows that the development of aeroengine technologies is being accelerated.
Facing the 21st century of knowledge and economy, challenge and opportunity run together, difficulty and hope go in parallel. We must seize the chance, go along with the trend to speed up the aero technology development in China. Views and proposals are given in this paper.
