Quelques vieux liens http: It expects to run the core demonstrator in the second half of next year. The company said it has completed the advanced study phase and is ready to launch the demonstrator program.
Versions of the engine power aircraft in service with operators in countries; more than 6, have been produced and have accumulated more than million flying hours. Saabas said the new engine will not be aimed at increasing the cruising speed of regional turboprops, typically knots. The PW models featured two-spool, two-stage centrifugal high-pressure compressors, the more powerful PW moving to a three-stage axial design.
Both had single-stage low and high-pressure turbines. Tugbopropulseur new engine will benefit, said Saabas, from the same three-dimensional airflow visualization technology used for development of the PWG and other new turbofans. The emphasis will also be on reducing ownership costs through increased component lifetime and longer maintenance intervals.
While the Talon combustor cuts NOx emissions in half, according to the company, overall greenhouse gas emissions will decline at least in proportion to the percent fuel burn improvement on which airlines insist for a new turboprop such as the NGRT. The airframers have got to decide the size of airplane they want.
Once it reaches that milestone, the engine maker hopes to officially launch the program and test the demonstrator core next year. Given those assumptions, it expects it could ready an engine for certification sometime in or The design would offer an optimum range of between and nm, said Dussault, and target a niche that had once belonged to smaller turboprops but has become saturated with less fuel-efficient seat jets. At a certain point in time there were many turbpropulseur platforms, there were a lot of players, it was a growth market and then there was the era of the jet for the longer range, which sort of dominated for a while.
GE, which owns Dowty Propellers and whose Middle River Aircraft Systems subsidiary holds a stake in Nexcelle, says it can develop and supply a complete propulsion system by Bombardier and ATR have each talked about introducing turboprops larger than their respective Q and ATR 72, but neither has offered much detail recently utrbopropulseur its plans.

While the two companies agree that power levels must depend on design cruise speed and aircraft size, both courz studies envision the use of eight blades to address higher noise levels otherwise arising from increased tip speeds of ever larger propellers. The Canadian engine firm began testing compressor elements last year. Overall, the company has established a comprehensive testing program for this year.
C’est un peu se remettre enfin, au niveau des nouveaux turbo-fan.
