Increasing the temperature at which jet aircraft engines operate would significantly improve thrust and fuel efficiency with reduced emissions. However, current engines operate within 50 degrees of the inherent melting point of the conventional materials used in engine construction. Thus, new materials capable of operating at higher temperatures for prolonged times must be developed and manufactured.
Ceramics and ceramic matrix composites (CMCs) can operate at temperatures in excess of 2000°F but are difficult to fabricate into the complex shapes required for jet engine use and consequently, novel manufacturing processes must be developed and processing conditions optimized for routine production of complex components.
To support the development of these innovative manufacturing processes, AltaSim Technologies has applied COMSOL® Multiphysics to the simulation of manufacturing processes for the production of CMCs. The software has been used to develop specialized multiphysics simulation technologies that describe the infiltration of molten material into a ceramic preform.
