Titanium alloy technology is an important symbol for measuring the advanced degree of aircraft and engine. The Fifth China aviation material and processing technology summit is held in Beijing
In November 30th, the 2017 (fifth) China aviation material and processing technology summit, hosted by the China Aeronautical Society, was held in Beijing.
As the summit invited guests, from Chinese Research Institute of Beijing Institute of Aerial Materials Hangfa titanium alloy Huang Xu made "development trend and application of titanium alloyin aviation products" in the theme of the report at the forum, he from the overview of the application of titanium alloy and titanium alloy for aviation classification, helicopter structure of titanium alloy and titanium alloy for engine the research and development of the situation and the development trend of application of titanium alloy in five aspects introduced the "13th Five-Year" focus on the development of new materials of titanium alloy. He introduced that, with the investment and technology improvement in recent years, many new alloys have their own intellectual property rights, including some key technology, such as extrusion, embryo and so on, which have formed a large number of patents. The Institute of air material will continue to carry out the exploration and research, and continue to open up the innovation of the titanium alloy materials for the titanium alloy engine forgings as a whole.
Precision casting of single crystal superalloy blade has become the key technology of aero engine
The processing of aeronautical materials directly determines the application of aeronautical materials, and the processing technology is closely related to the aeronautical materials. Precision casting and machining process of high temperature materials by China Hangfa Beijing Institute of Aerial Materials has been committed to the research of single crystal blade. China Hangfa Beijing Institute of Aerial Materials deputy director Luo Yu in the forum site with the material properties of single crystal superalloy as the breakthrough point, emphatically introduces the casting process of single crystal blade and present application status. He pointed out that the manufacturing technology of single crystal blade is going forward, and the future of high temperature alloy materials will continue to be low cost and high reliability.
The application of composite materials on aircraft is a trend
In recent years, the amount of the mainstream civil aircraft composite materials has been greatly improved. The amount of the compound material used in the Airbus A350XWB model is about 35%, and the amount of the composite material of the Boeing 787 model is 50%. From the aviation industry the first aircraft design and Research Institute deputy chief designer Wang Qianping in the "design and forecast" large aircraft composite structure theme report describes a flying Aviation Industry Institute in the design of large transport aircraft composite structure research, material foundation, design, development, manufacturing, testing process and other aspects of the trial delivery to do some to explore and try to project. At present, has established a set of large transport node strength design criteria, composite construction method and platform; completed the design specification documents related to nearly more than 100 copies; the process specification, the relevant test specifications, product quality certification and accreditation documents; also established a test planning system based on the requirements of airworthiness verification of composite.
Commercial airliner has been in demand for advanced Al Li alloy materials
The forum second days, Chinese fly Shanghai aircraft design and Research Institute standard material model designer, director researcher Li Hongping introduced the third generation of aluminum lithium alloy in the application of domestic and foreign models in a keynote speech, and the advantages of large aircraft with the third generation of aluminum lithium alloy brings. The future is considered to be applied to the wide body airliner project to improve the weight loss efficiency of the airliner.
The summit attracted hundreds of domestic and international aviation materials industry experts, focusing on research and development of advanced aircraft materials and applications, aircraft interiors, intelligent manufacturing, high-end equipment innovation, aircraft structure design, processing technology, user needs and other aspects of the issues in-depth discussion, promote information sharing and cooperation between enterprises project participants.
