Snecma and GE Aviation are developing new materials to make future engines lighter and improve their efficiency. In the works are alloys using exotic metals such as niobium, and composites using organic, ceramic or metal matrices. The two companies will employ these technologies for the Leap-X engine they are developing under their CFM joint venture (Hall 4 Stand B13) and possibly for other projects.
Bombardier Challenger 300 operators now have a choice of replacing the jet’s original nickel-cadmium main ship battery with a new Concorde RG-441 lead-acid battery. The FAA has awarded Concorde (Booth No. 2039) a supplemental type certificate (STC No. ST01488WI) for installation of the RG-441 lead-acid battery.
