Advanced materials research for long-haul aircraft turbine engines
The status of research efforts to apply low to intermediate temperature composite materials and advanced high temperature materials to engine components is reviewed. Emerging materials technologies and their potential benefits to aircraft gas turbines were emphasized. The problems were identified, and the general state of the technology for near term use was assessed.
Low Cost Process for Manufacture of Oxide Dispersion Strengthened (ODS) Turbine Nozzle Components.
Abstract : This final technical report describes a program for producing low cost processes for the manufacture of Oxide Dispersion Strengthened (ODS) turbine nozzle components. The processes established in this program will demonstrate that high pressure turbine vanes, low pressure turbine vanes and high pressure turbine bands can be manufactured from near-net shape components via directional forging and forge bending.
