Turbomeca plans to reduce the specific fuel consumption (SFC) of its turboshaft engines by 37 percent by 2030, and at the Helitech 2011 show discussed the strategies it is implementing to accomplish that change. While the company plans to make changes to the engine machinery, it expects much of the reduction to come from engine-airframe integration and new practices that make more efficient use of the engine.

News and issues regarding all manner of civil and military rotorcraft powerplants.
As the Eurocopter EC145 T2 light twin helicopter has completed “hot and high” testing, the manufacturer has released “promising” performance estimates.
The Pratt & Whitney Canada PW210S, which will power the Sikorsky S-76D helicopter, received Canadian certification on October 14, P&WC announced yesterday. Test engines logged more than 8,700 hours in test cells and flight tests as part of the approval process.
Eurocopter expects that its recently tested helicopter hybrid power concept will enter commercial service, soon perhaps as early as next year.
Eurocopter is upgrading most of its product range, with the goal of providing improved performance and reduced costs. The manufacturer is reporting progress on the developments of the AS350B3e Ecureuil (AStar), EC135T2e/P2e, EC145T2, AS365N3e and Super Puma L1e/C1e. All were announced at Heli-Expo 2011 in February.
The AgustaWestland AW189 medium twin helicopter will be the first civil application for Microturbo’s e-APU, an auxiliary power unit that delivers essentially electric power.
The chairman of Canada’s Transportation Safety Board (TSB) wants a mandatory 30-minute “run dry” requirement on all main gearboxes (MGB) for future helicopters. Wendy Tadros’s remarks came as part of the TSB’s investigation of the March 2009 fatal crash of a Sikorsky S-92A off Newfoundland, 11 minutes after its MGB ran out of oil.
Sikorsky has announced the end of the S-76C++ production run, thus firming up S-76D delivery plans for this year. The S-76D is undergoing flight testing, with a goal for FAA sea-level certification in the fourth quarter.
The European Union market is a “top priority” for Russian Helicopters, and the manufacturer does not want to limit those Russian-made models that are in operation there to rescue and firefighting.
Special conditions for the Pratt & Whitney Canada PW210S turboshaft, which is powering the in-development Sikorsky S-76D, have been issued by the FAA and are now effective, on the grounds that the engine has “a novel or unusual design feature”–engine operation in APU mode. Despite the additional testing required, certification of the engine is still targeted for September.
