Ground Testing of a CMC Engine Exhaust Nozzle on R-R Trent 1000
Ground testing of an engine exhaust nozzle made of ceramic matrix composite (CMC), which is designed to make engines quieter, lighter and more efficient. Boeing Research & Technology led the test team, which included engineers from Commercial Airplanes and Rolls-Royce. The CMC nozzle is installed on the back of a Rolls-Royce Trent 1000 engine at the engine manufacturer’s test facility in Stennis, Mississippi. The test focused on three areas: validating and correlating temperature predictions, demonstrating installation of the CMC nozzle on the engine and accumulating run time on an engine to qualify the nozzle for flight testing. New-generation engines on commercial airplanes are more efficient, but require materials capable of withstanding higher temperatures than previous engines. Ceramic matrix composites offer the potential of better thermal and structural performance while helping to reduce weight and acoustic footprint. The work is in support of the Federal Aviation Administration’s Continuous Lower Energy Emissions and Noise (CLEEN) Program. The CLEEN Program is a cost-share program with the FAA to conduct ground and flight demonstrations of airframe and engine technologies with the potential of reducing greenhouse gas emissions and community noise.
