Snecma plans soon to start another phase of open-rotor engine testing using a one-fifth scale model, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be. The concept, based on contra-rotating high-speed propellers, may not find itself in service before 2025. Nevertheless, trials aimed at cutting noise while retaining the huge efficiency advantage of the open rotor’s architecture are well under way.
The European Aviation Safety Agency has issued type certification for the higher efficiency and thrust “package C” version of Rolls-Royce’s Trent 1000 engine. The approval comes ahead of the anticipated first flight of Boeing’s 787-9 widebody. The 74,000-pound-thrust turbofan is set to power Air New Zealand’s first 787-9 when the new version of the Dreamliner family enters service next year, and it is also available for the existing 787-8.
CFM International—the 50-50 joint venture between GE and France’s Snecma—has started testing the first full Leap turbofan engine, the company announced Friday. The Leap-1A—one of the powerplant choices for the Airbus A320neo—fired for the first time on September 4, two days ahead of schedule.
GE Aviation started testing its new fourth-generation composite fan blades for the new GE9X turbofan, the company announced last week. Chosen to power the new Boeing 777X, the 100,000-pound-thrust-class engine promises a 10-percent fuel burn improvement over the GE90-115B–the engine that powers the Boeing 777-300ER.
Airwolf Filter Corp., a specialist in remote-mounted oil filter systems for piston aero engines, has scored a first. Over the past year, a team from the Middlefield, Ohio-based company has identified has identified every aircraft data sheet on file with the FAA and EASA and added to their approval model list every remaining piston-engine aircraft powered by a Continental, Curtiss-Wright, Franklin, Husoi, Jacobs, Kinner, Lycoming, Ranger, Warner or WSK PZL Kalisz engine.
Aero engines continue to represent “a robust investment opportunity” for those trading in the market for leased spares, according to the International Bureau of Aviation (IBA). However, the UK-based consultancy’s 2013 Engines Value Book, published last week, shows significant variations in engine values and shifts in demand for leased powerplants.
CFM International, the General Electric/Snecma joint venture, expects to begin a second phase of ground testing for its 3-D woven resin transfer molding fan with its Moteur à Aubes de Soufflante en Composite Taille (Mascot) 2 fan-demonstrator engine. The fan is “foundational technology” for the CFM Leap engine that is scheduled to enter service in 2016.
International Lease Finance Corporation (ILFC) has been busy announcing a procession of airframe and engine deals here in Paris. On Tuesday, the company announced it had signed for CFM International Leap-1A engines to power a further 20 Airbus A320neo jetliners. That brought the total backlog to 60 shipsets. With the aircraft scheduled to begin deliveries in 2016, the new order is valued at $510 million.
Russian aviation executives said the Irkut-led MC-21 narrowbody airliner development program is proceeding according to schedule. At a Paris Air Show briefing on Tuesday, program officials said the design is frozen on the first aircraft in the series, the MC-21-300, and parts manufacturing has started.
