Fan containment cases for jumbo jet engines

摘要

Alliant Techsystems (ATK), USA, has received a five-year, multi-million dollar contract from General Electric, USA, to produce fan containment cases made of fibre reinforced plastic for the GEnx aircraft engine. The GEnx engine - described by its maker as the world's only jet engine that incorporates both a front composite fan containment case and composite fan blades - is designed to provide lower operating costs and greater fuel efficiency for the Boeing 747-8 passenger aircraft. The use of composites will reduce the aircraft's weight, increase its payload capacity and extend its range, ATK says.
