    Now if they can speed up the mass production of Y 20
    We only have 4 production model sofar
    The Y-20A celebrates its first anniversary in the Chinese Air Force.

    Y20_WS20engine.jpg

    July 16, 2016, China's large domestic transport transport transport -20 "Kunpeng" formally delivered to the Chinese Air Force. In the past year, the outside world from time to time came the news of the Grand Engine. In the transport -20 service on the occasion of the first anniversary of the recent, the Chinese aviation industry, academic journals came the good news: China Yun-20 engine turbo-20 developed to achieve an important time node, from the equipment in the transport - 20 The day of the test flight is not far away.

    According to the report, based on the full technical preparation, the completion of the first domestic channel than the turbofan fan fan dynamic stress measurement test flight to fill the domestic test field of technical gaps, mastered the engine fan blade dynamic stress test flight test technology for China Aircraft engine rotor blade dynamic stress measurement development test flight and airworthiness certification test flight laid the foundation.


    According to statistics from foreign authorities, about 60% to 70% of aeroengine failure is structural strength failure, which, in turn, the highest proportion of blade failure.

    From the large channel than the turbofan engine research and development progress, and the report of the author of the unit is the China Flight Test Research Institute, China Aviation Shenyang Institute of Engine Research, not difficult to judge, the engine is for the domestic transport -20 large military Transport aircraft supporting the development of the turbofan -20 engine.

    Figure: Turbofan-20 engine (the second number of the second) is significantly larger than the D-30KP-2 engine to a circle


    From the above reports can be speculated that the domestic turbo-20 engine has entered the key "design stage", close to the design stereotypes. At this stage, the main task is to carry out key component structural integrity tests, which are important for accessories testing, environmental and swallowing tests, engine external features and fuel tests, engine lifespan life endurance test and altitude test, and throughout the flight bag Line to test, to carry out reliability, maintainability, testability, safety and life assessment. If at this stage, can draw a design can be designed to start a small batch of leading conclusions, then you can turn into the "production stage"

    "Production stereotypes" refers to the engine put into mass production, in order to promote the use of the engine mature, to carry out a small batch of leading use, simultaneously to carry out the engine life test, and the quality of the engine stability and mass production conditions for a comprehensive assessment. Then we will see the turbo fan -20 equipped with the target model - transport -20 transport aircraft to carry out flight test work. At this stage will further assess the engine reliability, maintainability and security and life assessment, if you can, then it means that the turbo-20 will be able to use large quantities of equipment.

    According to public information, the turbo fan -20 is a large channel than the engine, its overall performance is significantly better than the D-30KP-2 engine, Yun-20 dresser fan -20, due to improved engine performance, its range and The load can be effectively improved. In particular, it should be noted that the maximum takeoff thrust of the turbo-20 can reach about 15 tons, this indicator has been close to the United States C-17 transport aircraft 17 tons. In short, the turbo-20 service will provide ample power reserve for the various improved models in the future. It should be said that the turbo-20 is an urgent need for an engine in China, its performance and production capacity will have a direct impact on the future performance of the performance and production capacity. In the future, the engine can not only serve as the engine of China's Grand Canal, but also as a major passenger aircraft, the second generation of long-range anti-submarine patrol aircraft, and even flying wing layout long stealth bombers the main driving force, so its importance can be imagined.

    The same time as the above-
    The Irish 76 transport aircraft with the turbofan-20 engine flew at low altitude

    As early as the 2016 National Committee during the two sessions, the CPPCC National Committee members, transport -20 chief designer Tang Changhong in an interview with the media, said the shipment WS-20 to install the domestic engine has a timetable, he said, "probably next year or next year You can see the loaded with the domestic engine shipped -20.

    In the end of 2016, according to the local media reported in Xi'an Yanliang, a transport Y-20 appeared in the road. The scene of the photo and video shows that compared with the already open to the various transport -20, this test machine engine pence has undergone a significant change, which shows that the first improved model of transport -20 will be decorated with domestic turbofers - 20 engine.

    The same time as the above-
    2016 at the end of a transport -20 appeared in the road, the engine rack is significantly different from the previous

    Prior to this, the turbofan-30 engine has been in the China Flight Test Institute's Il -76 testing machine for many years of testing. In short, combined with a series of public information to see, we see the installation of domestic engine shipped -20 time has been getting closer. (Author's signature: camouflage)
