In fifty years' hard course, avic turbine courtyard has been committed to realize the autonomous development of aeroengine, accumulated in long-term difficult for professional engine test technology, developed for the validation of the model design, breakthrough technology, provides the technical ideas and data support.For nearly a year, working in the turbine house of superior departments organization model developed review meeting, experts said: "the turbine courtyard innovative testing technology, developed for these models out of the situation to move forward, get through the road."

        In order to ensure the aircraft engine and its system reliable work, must carry out a variety of strict test.Design calculation method development soon, but still could not have the engine may be met in the practical work of all complex situations into consideration, can only rely on a large number of actual test experience and data to improve the design and calculation method for strong support.For this purpose, catic industrial turbine always adhere to the "engine is try out", in the face of aviation engine working in high temperature and high pressure, high speed and high load is extremely stringent test conditions, such as targeted to develop test technology professional work, new test method, and raise ability, speed up the test equipment test equipment independently.
          The blockade of key test technology from abroad, realizes automatic test technology development, will to a great extent, is conducive to China's engine developed independently.Therefore, turbine testing technology development the same as the scientific research project tasks, developed in recent years, such as nano thermopaint, infrared temperature measurement, wireless telemetry, dynamic stress test, high temperature dynamic stress measurement and a series of innovative testing technology, as well as the development of engine test software, realize the engine test information, such as technology, and applies these technologies successfully into engine model development test.Turbine institute combining technical research need to develop some test technology and application of targeted reveals some technical problems, the failure mechanism, better to carry on the design improvement and perfection.
          Turbine courtyard "type of inventions and patents," let the domestic testing technology in the field of envy.A "based on the isotherm interpretation of thermopaint test technology", has won more than 20 invention patents.The technology solves the aeroengine high temperature parts surface temperature field measurement in our country, especially the high pressure turbine disc rotating parts, such as turbine blades and the compressor plate wall temperature testing technical problem, applied to turbine court scene gas turbine test of high temperature components, and presided over drafted two industry standards.Has been successfully used in a certain type of engine on the infrared temperature measurement technology for the first time in China, the application of the technology in high pressure on the blade through the cooling design, structure design, the emission rate test and so on many key technologies.High temperature dynamic stress testing technology is also a major bright spot, just a few short years time, the survival rate of high temperature strain gauge, dynamic data collection and analysis technology is also gradually perfect, advanced rotor signal wireless telemetry technology also gradually on the test.Also, turbine test by the sense of design technology has also got the inheritance and development, based on the sense of the advanced design level, turbine house painted "as China's strongest pneumatic thermal probe research and development center, high temperature test technology on the international leading level", "building a domestic first full of sense of design, processing, calibration, strength check specifications" vision is just around the corner.In turbine house, like this continuously innovation and development of test technology still has a lot of, also has formed the standard test specifications, and can quickly popularized, power model is developed.
          Test as one of the four main technical system engine, its development level directly about engine model development process.Turbine courtyard testing technology development, with progress, with the engine has been 50 years of testing technology accumulation makes the college, with a complete set of engine test system, independent development of testing technology accomplished gradually standardized and even transition.Turbine hospital continuously broaden the application of testing technology platform and channel, as far as possible the test technical advantages into product advantages, constantly practice the "air of patriotism, the motherland prosperous common people" sacred mission, to develop a measurement and control products, test infected, non-standard products, measurement and control platform, measurement and control engineering contracting, measurement and control technology services six major categories of products, and have a certain market size and stability of the user.Courtyard outside the measurement and control business contract order is increasing year by year, the user is more about a turbine advanced testing technology of the courtyard.At the same time, with the domestic companies, universities, scientific research institutes to establish a joint development of test technology product relations of cooperation.
           Now, the turbine testing technique are moving in the interference, non-contact, special test and controller design techniques such as optical, acoustic and semi physical simulation technology, such as the new direction.Its testing technology business display "conquer the technological frontier, develop dual-use products, create economic benefits and social benefits" business philosophy, to fall to the ground in turbine hospital scientific concept in specific professional.(yuh-fang chang wen guang China aviation news)
