Pratt & Whitney’s EcoPower engine wash for the F117 turbofan is helping the worldwide C-17 fleet achieve an 85-percent mission-capable rate, despite the aircraft routinely operating in harsh conditions. EcoPower reduces fuel burn by 1.2 percent, as well as carbon dioxide emissions and exhaust gas temperature.

The Europrop TP400 engine that has been fitted to a C-130 testbed at Cambridge, UK, by Marshall Aerospace ran at full power for the first time last week. But unanticipated problems integrating the 11,000-shp powerplant on the C-130 have further delayed the A400M program.
GKN Aerospace has delivered Blended Winglets for 767-300ER aircraft to Aviation Partners Boeing (APB) for certification flight tests in support of launch customer American Airlines.
The contract has involved the design and development of an 11-foot-tall winglet and will include manufacture of some 450 shipsets, with forecast peak production of up to 16 shipsets per month.
Powering the A400M was always going to be a challenge, requiring the development of the Western world’s biggest turboprop, the 11,000-shp TP400-D6, and integrating a host of highly complex systems and associated software. “The complexity of the integration task on the TP400 has been bigger than it was for the Airbus A380,” said Nick Durham, president of Europrop International (EPI).
One of the biggest problems for those designing the next generation of unmanned combat air vehicles (UCAVs) is how to define, choose and incorporate a powerplant. Rolls-Royce believes it has the answer in a new type of engine system that has a much hotter core and provides not only power to the airframe, but also manages the entire power requirement of the UCAV. However, it doesn’t have the money for the program–at least, not yet.
Sukhoi Civil Aircraft hopes to make the first engine runs on its PowerJet SaM146-equipped Superjet 100 this week as it awaits authorization to begin flight tests that it now says could take place in about a month’s time. A second aircraft, now undergoing completion, could fly before June, according to Sukhoi.
The debate about the design of future commercial aircraft engines broadened this year as concerns mounted over the effect aircraft engines may be having on global warming, while the cost of aviation fuel rocketed and noise became ever more of an issue.
The Royal Saudi Air Force has chosen General Electric (Stand C410) to re-engine its Boeing F-15S fighters with the F110 powerplant. Deliveries of 65 of the F110-GE-129C engines are to begin in 2008. Including logistical support, the contract is valued at more than $300 million.
The Elisra Group is showcasing a wide range of specialist products, from UAV sensors and IR protection systems to a new immune satellite navigation system at its exhibition in the Israel Pavilion. Seventy-percent owned by Elbit Systems, the Elisra Group consists of three principal constituents: Elisra Electronic Systems, Tadiran Electronic Systems and Tadiran-Spectralink.
It seems there is no slack left in the Europrop TP400-D6 turboprop engine program for the Airbus A400M military transport.
