With 53% of all 787 orders, the GEnx is the most popular choice with the Trent 1000 accounting for 33%. In addition to the improved fuel burn requirements, the 787 propulsion system also had to meet more stringent noise and emissions requirements. The engine test program incorporated more than 20 dedicated test engines between the two engine manufacturers. Boeing reported to the FAA that the engine manufacturer recently determined that intermediate pressure compressor (IPC) stage 2 blades have a resonant frequency that is excited by the airflow conditions existing in the engine during operation at high thrust settings under certain temperature and altitude conditions. Central maintenance system. Through centralized fault reporting, the 787 onboard maintenance system (OMS) aids the airline mechanic in rapidly isolating faults and guiding the appropriate maintenance action (see fig. A two-year, six-airplane 787 flight test program led to type certification in August 2011 and entry into service in October 2011. The Trent 1000 engine is a three shaft high bypass ratio, axial flow, turbofan with Low Pressure, Intermediate Pressure and High Pressure Compressors driven by separate turbines through coaxial shafts. What is Scheduled and Unscheduled Aircraft Maintenance? So the nozzle must be smaller than that as the engine assembly narrows at its rear end. This PDF (p.5) shows a diagram of the exhaust nozzle of RR Trent 1000 measuring the diameter as 63 inches. Delta Material Services The LP ompressor fan diameter is 2.85m with a swept fan blade and OGV’s. Highlights include: This view of the nacelle shows the inlet, fan cowls, thrust reverser, exhaust plug, and nozzle. Intense engine development and 787 flight test programs contribute to the engines’ service readiness and durability. A secondary parameter goes out of normal operating range. Incorporate an entirely new composite fan case for significant weight savings. Enhancing Suppliers’ In-Service Support to Airlines, New Process for Component Removal Reduction, Securing Airline Information on the Ground and in the Air. • Best engine for the Boeing 787 Dreamliner. This Comment /Replies Record Will Preminentaily Delete ,Are You Sure ? Introduce surface air-oil coolers to compactly reject the VFSG and engine oil heat. 1775 M H Jackson Service Road Incorporate state-of-the-art titanium aluminide (Ti-Al) blades in the last two stages of the seven-stage low pressure turbine. The 787 propulsion system incorporates the latest generation of central maintenance and engine health management systems. The article focuses on how the design achieves fuel consumption, noise, and emissions improvements and discusses operating and maintainability features as well as overall cost-of-ownership reduction benefits. Simplifies the auxiliary power unit (APU) design to be a shaft power-only machine. A proven translating sleeve thrust reverser system that utilizes compact state-of-the-art 5,000 pounds per square inch (psi) hydraulic actuation. Dj's Aviation Recommended for you. Controls bus configuration and engine health monitoring. Managing the power distribution between the VFSGs is the bus power control unit (BPCU). The engine test program was started far in advance of the Boeing flight test program. the highest bypass ratio of any Trent engine 10:1. After 3 superseded AD, EASA issue Airworthiness Directive, The US Federal Aviation Administration FAA has limited Dreamliners Model 787-8 and 787-9 airplanes, certificated in any category, powered by Rolls-Royce plc (RR) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 turbofan engines to.
