NASA Glenn has been directly involved in the effort to bring these materials to turbine hot section components. The NASA Ultra Efficient Engine Technology program (UEET) is focused on driving the next generation of turbine engine technology. One of the major thrusts is the development and demonstration of advanced high temperature materials which are capable of surviving the extreme environments of turbine combustion and exhaust. In the commercial sector, the Rolls Royce Trent 1000 and Trent XWB engines are being developed for the Boeing 787 and Airbus A350 XWB aircraft, respectively. There are currently 1030 Boeing 787s on order or flying and 814 Airbus A350 XWBs on order. The Trent 1000 was the launch engine for the Boeing 787. These are large markets where the benefit of this technology will have a lasting impact in efficiency and cost. By working closely with Rolls Royce during the early stages of this development program, MR&D has ensured that the resulting products will meet the requirements of future customers. Rolls Royce has expressed a serious interest in this technology and, as demonstrated above, has a sizable market for its application. The aerospace industry is not the only potential beneficiary of this technology. The Department of Energy (DOE) is working hard to improve the efficiency of power generators. Just as with aircraft engines, power turbines' efficiency improves with higher operating temperatures. As an example, current turbines operate at 2600F, which provided a large improvement in efficiency over earlier models operating at 2300F. CMC turbine blades and stators will allow even higher temperature operation and is a topic which the DOE is currently investigating.
