Collective Technologies unit Pratt & Whitney (P&W) has concluded ground testing of its next-generation Geared Turbofan (GTF) apparatus propulsor technology in West Palm Beach, Florida, US.
The test was conducted as involvement of the US Federal Aviation Administration’s (FAA) Continuous Lower Energy, Emissions and Clamour (CLEEN) programme, a FAA NextGen initiative that seeks to expedite the occurrence of environmentally friendly aircraft technologies.
The full-scale test continued for myriad than 175h and was built upon the 275h-long fan rig testing of the technology escorted in 2014 and 2015.
“The success of this ground test is an important step in compelling our GTF engine technology to the next level.»
A development engine from a certified Geared TurboFan result was used to confirm the performance of a second-generation, ultra-high bypass fan design.
The locomotive product successfully operated in the new design features less lower-pressure correspondence blades than the current production engine and a shorter duct inlet.
The evaluates are estimated to demonstrate a set of technologies that will help reduce encourage consumption by 2% more than the current generation of GTF engines.
Pooled Technologies’ computational fluid dynamics (CFD) tools were used to develop the new engine propulsor technology.
The tools are designed to offer accurate forecasts and design guidance to allow rig-to-engine scalability, as well as improved deportment to the engine and can help meet FAA’s CLEEN goals.
P&W technology and environment vice-president Alan Epstein disclosed: “The success of this ground test is an important step in taking our GTF mechanism technology to the next level.
“We are working to make sure the next-generation GTF mechanism, already a game-changer, remains on the cutting edge of performance and sustainability.”
In besides, P&W has collaborated with FAA to advance a compressor and turbine technology as part of the CLEEN II schedule, a follow-on project aiming to develop and demonstrate aircraft technology and surrogate jet fuels.
