Modern commercial and military aircraft are requiring unprecedented fuel efficiency and performance.  There are many challenges and opportunities regarding the development and deployment of materials for aircraft power systems.  Aircraft power systems are not limited to the advanced turbine engines where increased temperature capabilities, sealing, aerodynamics and aerothermal technologies are being enhanced.  Power requirements for modern and future aircraft are demanding many more systems to be considered for system-wide performance improvements.  Materials that support electrical power and fluid handling are also critical for optimum performance and minimized system weight.  Additionally, power optimized aircraft (POA) require systems to be robust and resistant to environmental effects.
