Traditionally turbine blades in aircraft engines have been metal (left). Now, ceramic matrix composite (CMC) versions are being explored (right) enabling higher temperatures and lower weight for more ...

The engine has one CMC component, a turbine shroud lining its hottest zone, so it can operate at up to 2400 F. The CMC needs less cooling air than nickel-based super-alloys and is part of a suite ...

For the first time, GE has tested a ceramic matrix composite (CMC) turbine blade in a working engine. Although the 4h-test is only the beginning in a long series, it means CMC receives credit ...

GE’s first CMC parts to enter service will be the static first stage HP compressor shroud in the LEAP engine. Also called HP turbine shrouds, and reportedly some of the hottest parts in a turbofan, 18 ...

An engine built by GE Aviation and a joint venture partner will be the first featuring ceramic matrix composite material in a commercial setting. High-pressure turbine shrouds, which direct air ...

The project will also develop a continuous process chain and corresponding manufacturing strategy for the production of turbine blades for both CMC and additive manufacturing. Especially for CMC ...

Low-pressure turbine blades in silicon-carbide ceramic matrix composite for F414 adaptive cycle combat engine Lighter rotating parts Advance in CMC for jet propulsion Tests validate temperature ...

The engine builder reported its tests on a GEnx demonstrator engine fitted with GE9X CMC components for the combustor and turbine exhibited impressive durability over long-term service. The first GE9X ...

A new turbine profile was designed based on the engine-side boundary ... The complex blade geometry is a major challenge for the manufacturing process, especially for CMC materials. The up-scaling of ...

The Asheville facility fabricates CMC shrouds for the LEAP engine’s high-pressure turbine section. In addition, GE’s Power and Water business is testing CMCs in its newest and most efficient ...

Current CMC/EBC technologies can withstand temperatures ... (1,482C) to enable higher turbine efficiency and power outputs. Nevertheless, significant efforts to enhance existing EBC systems ...
