The document discusses several advanced materials processing techniques including powder processing, sol-gel processing, thermal oxidation, sputtering, pulsed laser deposition, and chemical vapor deposition. It also discusses applications of these techniques such as coating ceramic outer air seals on gas turbine blades and depositing optical fibers. MEMS applications are explored including uses in biotechnology, chemical detection, adaptive optics, and miniature sensors and actuators.

2. HPT Airfoil Material Advances Material advances allow the use of higher metal temperatures and/or less cooling air. Ceramic layer Metallic layer Ni or Co base Gary Chaplin, Pratt & Whitney

3. PW4000 Material Technologies Ceramic outer air seals are combined with abrasive coated blade tips to create an abradable system that reduces turbine operating tip clearance. Shown below is the continuously graded ceramic outer airseal segments that have been successfully cut by a sprayed abrasive blade tip system. Brush seals can significantly reduce leakage relative to KE seals. The static seal’s cobalt alloy brush wires are in constant contact with a ceramic coated rotating seal land. Brush wear is determined by the interference load & the surface speed & temperature. Gary Chaplin, Pratt & Whitney

4. Space Port to be Built in New Mexico A core group of 100 “founders’ have paid the initial $200,000 cost of a flight up front. Flights will begin in late 2008 or early 2009. Spaceport construction should begin in early 2007. Virgin Galactic’s Richard Branson has a deal with Burt Rutan to build 5 space craft Gary Chaplin, Pratt & Whitney
