In the arduous course of 50 years, AVIC Turbine has been committed to the independent development of China's aero-engines. It has accumulated professional engine testing technology in the long-term and difficult exploration, which is the verification design and breakthrough technical difficulties for the model under development. Provide technical support and data support. In the past year, at the review meeting of the turbine model development work organized by the superior department, the experts said: "The innovative testing technology of the turbine hospital has continued to advance for the development of these models and opened the way." In order to ensure the reliable operation of the aero engine and its systems, a variety of rigorous tests must be carried out. The design calculation method has developed rapidly, but it is still impossible to take into account all the complicated situations that may be encountered in the actual work of the engine. It can only rely on a large amount of actual experimental experience and data to strongly support the improved design and calculation methods. To this end, AVIC Turbine always insists that “the engine is tried outâ€. In the face of extremely harsh test conditions such as high temperature, high pressure, high speed and high load of aviation engine work, the professional work of testing technology is vigorously carried out in a targeted manner. Test methods, improve equipment testing capabilities, and accelerate the independent development of test equipment. Freeing the foreign blockade of key test technologies and realizing the independent development of test technology will greatly facilitate the independent development of China's engines. Therefore, Turbine has also developed test technology development as a research project task. In recent years, it has developed a series of innovative test technologies such as nano temperature paint, infrared temperature measurement, wireless telemetry, dynamic pressure test, high temperature dynamic stress measurement, etc. He also mastered the development of engine test and test software, and realized engine test information technology, and successfully applied these technologies to the engine model development test. Turbine yard combined with technical research and development needs to develop some test technology and its application, specifically revealing some technical problems, the mechanism of failure, better design improvement and improvement. As one of the four major technical systems of the engine, the test level is directly related to the engine model development process. Turbine testing technology and engine have been developing and progressing together. The accumulation of testing technology for 50 years has enabled the hospital to have a complete engine testing system, and the self-developed testing technology has gradually completed standardization and even productization. Turbine Institute constantly expands the application platform and channels of testing technology, transforms the advantages of testing technology into product advantages as much as possible, and constantly practices the sacred mission of “airline reporting to the country, strengthening the army and enriching the peopleâ€, developing measurement and control products, testing the sensing department, and non-standard Products, measurement and control vehicles, measurement and control engineering contracting, measurement and control technology services in six categories of products, and has a certain market size and stable users. Contracts for measurement and control business outside the hospital are increasing year by year, and users value the advanced testing technology of the turbine. At the same time, it has established cooperative relations with a number of domestic enterprises, universities and research institutes to jointly develop test technology products. Today, the testing technology of the turbine is developing in new directions such as non-interference, non-contact, optical, acoustic and other special tests as well as controller design technology and semi-physical simulation technology. The business philosophy of “conquering technology frontiers, developing military-civilian dual-use products, and creating economic benefits and social benefits†demonstrated by its testing technology business is precisely the landing of the research concept of Turbine Institute in specific professions. Concerned about surprises Expanded metal is sometimes considered an alternative to sheet metal or wire mesh. It combines some of the best features of both-providing a material that is stronger than thin wire mesh and has better air flow and drainage than sheet metal.

Turbine Institute "one type of invention, a number of patents", envy the peers in the domestic testing technology field. A "temperature-based paint testing technology based on isotherm interpretation" has won more than 20 invention patents. The technology solves the technical problem of surface temperature measurement of high-temperature components of aviation engines in China, especially the wall-temperature test of rotating parts such as high-pressure turbine disk, turbine blade and compressor disk. The turbine institute also promotes it to the high-temperature parts of the scene gas turbine. During the test, he presided over the drafting of two industry standards. The infrared temperature measurement technology that has been successfully applied to a certain type of engine is the first in China. The application of this technology on high pressure blades has broken through many key technologies such as cooling design, structural design and emissivity testing. The high temperature dynamic stress testing technology is also a bright spot. In just a few years, the survival rate of high temperature strain gauges has been greatly improved, and the dynamic acquisition and analysis techniques have been gradually improved. The advanced rotor signal wireless telemetry technology has also begun to be applied in trials. . In addition, the design and technology of the sensory part of the turbine hospital has also been inherited and developed. Based on the current advanced design level of the sensory department, the turbine hospital has drawn “the strongest aerodynamic thermal probe research and development center in China, and the benchmarking of high temperature testing technology. The development vision of “leading international level†and “establishing the first complete design, processing, calibration and strength check specification of the domestic sensing department†is just around the corner. In the Turbine Institute, there are still many test technologies that are constantly innovating and developing like this. It has also formed standard test and test specifications, and can quickly promote the application and help the development of the model.
