A mockup of an open-rotor engine has been tested in an Onera wind tunnel since 2010; a full demonstrator is due to run in 2016.

As preparations continue for running a full open-rotor engine demonstrator in 2016 under Europe’s Clean Sky research effort, French engine maker Snecma (Hall 4 Stand B12) sees the program’s participants reaching a consensus as whether or not to proceed in the 2017-to-2019 time frame. Clean Sky, which also involves Airbus, Rolls-Royce and French research center Onera, has provided a relatively unexpected discussion platform, thus facilitating a general agreement.

What turned out to be a big week for Boeing with the formal launch of its new 777X widebody also promises to be a big week for the engine that will power it, the GE9X. Dubai Airshow visitors can get a sneak preview of the 102,000-pound thrust turbofan through a new 3-D representation of the equipment at the GE Aviation exhibit (Chalet A9).

A day after watching Pratt & Whitney’s PW1500G engines lifting Bombardier’s new CSeries airliner for its long-awaited first flight on September 16, Pratt & Whitney Canada president John Saabas told AIN that the new turbofan’s PurePower technology PW800 cousin will soon be delivering the same step change in operating efficiency and low noise to the business aviation sector.

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.

Boeing’s confirmation in March that GE Aviation will provide the new GE9X engine to power its proposed 777X development marked the culmination of three years of preliminary work between the engine maker and the airframer in their quest to be in a position to promise a 10 percent reduction in fuel burn compared with the GE90-115B engines on the existing 777-300ER. Also promised is a 5 percent improvement in specific fuel consumption over rival widebody engines by 2020.

The price of maintaining Rolls-Royce Spey engines, which power the Gulfstream II and III, has dropped dramatically over the last several years, according to MRO shops and operators. Gulfstream made 460 GIIs and GIIIs between 1966 and 1987, but operators increasingly are scrapping them in response to rising fuel prices and more stringent anti-noise requirements that will require the installation of hush kits or restrict operations.
