some consensus in aircraft engines and weaponry industry: the engine is the bottleneck in the development of military systems; aviation engine is the most complex integration of high-tech products, its research and development capabilities represent a comprehensive scientific and technological strength of the country; Aero Engine R & D will ultimately depend on the level of the test and the test level, especially on the ground capable of simulating altitude simulation test and test the level of air working conditions. Ability and technical level of the country’s high-altitude simulation has become the country independently developed an important symbol of advanced aviation engine capacity and the level of altitude simulation is an important means and tools for independent research and advanced aero-engine integral, high-altitude station is the country’s strategic resources .
altitude simulation test technology and ability role and influence, not only in the fighter force and other military aircraft engines, transport aircraft and civil aircraft engines as well as unmanned aerial vehicles power is now also altitude simulation technology more and more urgent. The more prominent is the the current hypersonic vehicle research and development has begun to enter the stage of engineering applications, Development of hypersonic combination power even without the technical support of the high-altitude simulation test. Because of American leadership in the technical aspects of the high-altitude simulation test, creating the thriving situation hypersonic vehicle research areas in the world today.
2008 “5.12″ Wenchuan earthquake brought serious damage to the earthquake fault Key Laboratory of core equipment – high-altitude station, plant, equipment and infrastructure have been affected to varying degrees . Play its due and a huge strategic role in order to ensure that the country’s strategic resources, in accordance with the important instructions of the party and the state, the Central Military Commission and a higher authority, and with many years of use maintenance instructions spirit, Key Laboratory of experience in the design and construction of tenaciously extraordinary combat, carry forward the “Bearing in mind the great love to straighten the backbone of the party loyal to fulfill our mission,” the spirit of earthquake relief in challenging conditions independently launched a limited restoration of the old base and the new base for planning the design and construction work in 2010, the successful completion of limited restoration of the old base design, to restore the building and completion of the inspection work to ensure that the current key model simulated altitude capability of engine development and technical research models, the limited restoration design and recovery effect has been a high degree of recognition of superior authorities and completion of the inspection team. At the same time in 2010 planning argumentation, the overall design of the equipment size and ability level will reach the world’s third Mianyang new aviation engine altitude simulation test base. The construction work of the new base is progressing on schedule.
laboratory on the basis of the results achieved previously, further deepening the turbojet, turbofan, turboshaft engine and core engine altitude simulation test technology, aviation engine development should be carried out of the test subjects, working environment simulation methods, test processes, test performance/characterization and evaluation methods to supplement and improve basic altitude simulation technology system with independent intellectual property rights. Altitude simulation technology system initially built to provide direct technical support for China’s own development and the development of the aviation engine, so that laboratories really play the role of escort for our own development and the development of the aviation power.
With Mianyang test base built and put into operation, its testing capacity and scale to reach world-class level, advanced testing and test platform will provide engine technology. After the completion of Mianyang test base is bound to become a world-class aero-engine altitude simulation Key Laboratory.Share:
