Rapid growth in the demand for high temperature alloy industry and policy favorable aviation development
Power first, two machine special, leading materials. Policy support superimposed demand pull, the high temperature alloy industry will usher in rapid growth.
High temperature alloy industry since its inception, always focus on aviation engine performance improvement needs constantly, engine evolution from one generation to the four generation machine machine, high performance, low fuel consumption, higher durability is the trend of its development. The thrust weight ratio as an example, in the premise of engine turbine and fan design level under the same inlet temperature increase for each 100 cards, 15% increase in thrust. High temperature alloy engine occupies 40%-60% of the total weight, improve the engine performance forecast in the future, new material contribution rate will reach 50%-70%, and the contribution of materials and manufacturing technology of engine weight loss will be 70%-80%.
1, trends, and breakthrough single crystal ceramic composite A new force suddenly rises. base material
High temperature alloy can be divided into casting, deformation, three new types of alloys. The breakthrough of single crystal material in casting alloy will determine the development trend of the next generation engine. Ceramic matrix composites (CMC) and other non-metallic materials break through the temperature limits of metal alloys, is the future development trend. GE in the GE9X has made a successful attempt, CMC new material can maintain the same intensity under the temperature of 2200oF, the whole 500oF higher than metal, and metal weight is only 1/3, so that the engine fuel consumption efficiency of the world's leading. In June this year, GE new plant to produce CMC, the material is expected to be the future demand for rapid growth, but the current domestic costs are not subject to promotion. High temperature alloy industry has the characteristics of oligopoly and anti economic cycle, and the domestic long-term supply in short supply, the localization rate of 50%-60%, the gap between supply and demand showed an increasing trend.
2, hundreds of billions of funds is about to start, policy support and technical upgrading to promote the outbreak of industry demand
Policy, navigation policy release, "flying hair separation" landing, major aero engine and gas turbine will start in the second half of the year, hundreds of billions of funds will be flooded; technology, Taihang series engine variants launched, equipment is expected to f -11 and -10, in the domestic demand continues to accelerate, the civilian aspects of C919 in the second half of the first flight, the fastest delivery in 2017, marking the field to break the foreign monopoly, to fill the gaps, the engine demand will skyrocket. According to public data projections, the next twenty years, the field of high temperature alloy aviation demand of about 300 thousand tons, the market size of nearly billion over the next ten years; gas turbine field scale at around 5 billion, the field of atomic energy demand of 6000 tons, the size of 1 billion 300 million vehicles, 5000 tons of demand, the scale of 1 billion 200 million. On the whole, the industry will maintain a growth rate of over 15%.
3, a special machine two hundred billion funds to start soon, the first to take the lead in high temperature
In order to enhance the ability of independent innovation of China's aviation engine and gas turbine industry, in 2013 the State Council approved the establishment of a major aero engine and gas turbine projects of national science and Technology (the "two special"), the establishment of the Committee of experts to carry out feasibility studies on the specific implementation plan, in July 2014 two formally submitted to the State Council to implement the program of special machine.
The forthcoming special two machine will focus on turbofan, turbojet engine, and at the same time, there is a certain market demand of turboshaft and turboprop and piston engine, the main R & D high bypass ratio turbofan engine in large, small turbofan / turbojet engine, high power turboshaft engine and other key products. In addition, the special action will also be arranged for a number of industrial demonstration projects, including commercial aviation engine operations, aviation engine intelligent production lines, etc.. Advanced high bypass ratio fan system, high pressure compressor and other key parts, key technology and long-life turbine, advanced aviation composite materials, also is one of the key points of the special action.
Benefit from the two special machine of hundreds of billions of funds start, high temperature alloy industry will usher in the explosive growth opportunities. In accordance with the two machine special implementation plan, in 2020, the state will invest hundreds of billions of funds to support the development of aviation engines and gas turbine industry. The development of aviation, power ahead; the motive force of the development of materials, leading, we know that the "two machine special star of aircraft engines and gas turbines accounted for nearly 75% of high temperature alloy materials for downstream applications, mainly to promote the demand for high temperature alloy materials industry, the expected high temperature alloy industry ushered in the great historical opportunity period.
