Over the last 20 years, the aviation industry has documented more than 200 incidents in which turbofans have lost power during high-altitude flights, according to NASA.

Rolls-Royce is looking to expand its engine component manufacturing activities in India, possibly adding new product lines and increasing the size of the facilities at its International Aerospace Manufacturing Pvt Ltd (IAMPL) operation in Bangalore, which already makes parts for the Trent 700 turbofan.
Rolls-Royce on Wednesday revealed plans for a new generation of engine designs to replace the current Trent family. The first, called Advance, would reach the market by the end of this decade, burning at least 20 percent less fuel and emitting 20 percent less CO2 than the first generation of Trent engine. The second, dubbed UltraFan, would enter service by 2025 and use a geared design and a variable-pitch fan system capable of delivering at least a 25-percent improvement in fuel burn and emissions.
As CFM International and Pratt & Whitney progress toward the entry into service of their competing engines on the Airbus A320neo, the rival powerplant makers are at odds over which engine will deliver the best performance in terms of turbine temperatures.
GE Aviation this week reported that testing on the high pressure compressor (HPC) module for the GE9X engine that will power Boeing’s 777X aircraft continues to yield “very promising results,” achieving a 27:1 pressure ratio–the highest of any commercial aircraft engine. The tests began in September at the GE Oil & Gas testing facility in Massa, Italy, and the module has accumulated close to 300 hours of testing today.
CFM International is confident Comac’s C919 program is progressing on a sound basis, but the engine manufacturer does have contingency plans for the Leap-1C turbofan it has designed for the narrowbody to mitigate program risks in case further delays arise.
Regional airliner rivals ATR and Bombardier may still be no closer to announcing their long-anticipated new 90-seat twin turboprops, but Pratt & Whitney Canada (P&WC) is determined to be ready with the necessary powerplant for program launches that it views as inevitable. Next month, the engine maker will resume testing of the compressor unit for its proposed New Generation Regional Turboprop engine and it expects to have all testing complete by mid-year.
Rolls-Royce and Cathay Pacific have agreed a TotalCare support contract for Trent 700 engines that power Cathay Pacific group’s 60 Airbus A330 aircraft in-service and on-order with Cathay Pacific group airlines, Rolls-Royce announced in Singapore on Monday. The contract runs for as long as Cathay Pacific and its sister company Dragonair operate the Trent-powered A330s.
Cathay Pacific became the first airline to operate any Trent engine when its Airbus 330s entered service in 1995 and today it stands as the largest Rolls-Royce Trent 700 customer.
Three companies are competing to offer airlines a fuel-saving way to have their aircraft taxi with engines shut down.
As Rolls-Royce (Booth N23) prepares to begin a two-year development and testing phase for the latest Trent engine–the Model 1000-TEN, designed to power Boeing’s stretched 787-10 large twin-aisle twinjet–it has completed three full demonstrators and is building a fourth that will be used in a 500 flight-cycle trial.
