The French Safran Group recently signed an agreement to adopt advanced resin composite materials on LEAP aircraft engines. CFM International, a joint venture between Safran and GE, specializes in the manufacture of air engines for Airbus, Boeing and COMAC projects. .
According to the agreement, composite technology will be used to manufacture key structural components of the engine, including fan blades, fan casings, acoustic panels and packing grooves. The composite material was developed and produced by Solvay. Solvay is in Germany in 2016. A state-of-the-art resin plant in Stirling, which mainly serves the LEAP aero engine program. Some materials will be produced by Solvay from Osterling, Germany, and Solvay is also investing in and supporting the LEAP program.
Safran is a high-tech multinational corporation, a Fortune 500 company with four core disciplines: Aerospace Propulsion, Aerospace Equipment, Defense Security and Communications. The Group has 62,000 employees in more than 30 countries around the world. The company has a reputation of more than 11.3 billion euros. The Safran Group's subsidiaries are also well-known for their independent development or cooperation in the world or Europe. They also undertake the design of some European rocket and liquid booster propulsion systems. And development work.
Founded in 1863, Solvay is a multinational company headquartered in Brussels with a focus on key social challenges. The main applications of Solvay products include aircraft, automotive, batteries, smart medical equipment, high efficiency in mineral and oil extraction. And sustainability.
Thierry, vice president of materials procurement at Safran Group, said: 'Solvay has been a long-term trusted supplier to Safran, providing advanced composite materials in multiple engine and cabin programs. The agreement emphasizes not only continuing to strengthen the collaborative LEAP program, It will also strengthen another larger portfolio of linkages between the two groups.
Carmelo, president of Solvay Composites Global Business Unit, said: 'Safran's composite technology, expertise and safe supply chain will continue to support Safran's production of this highly innovative aero engine in the next few years. LEAP engine The design takes advantage of composite materials to reduce fuel consumption, CO emissions, noise and maintenance costs.
The resin composite material has light weight, and the specific strength is based on the development of aerodynamic design, structural design and composite technology. The composite fan blade can be further improved, and the specific stiffness is large, which can replace the traditional titanium alloy and other materials applied to the aeroengine. High aircraft thrust-to-weight ratio and fuel efficiency, reducing noise and harmful emissions, increasing comfort and economy. Composite materials can reduce fan and engine quality, improve specific stiffness, fatigue performance, damage and defect tolerance. Advanced composite materials are the only way to achieve higher bypass ratios and weight reduction at the same time, which also provides an opportunity for composite materials to be widely used in aeroengines.
