Safran spins up new turboprop design

摘要

Safran Helicopter Engines is actively considering the development of a turboprop version of its Ardiden 3 rotorcraft power-plant to challenge the Pratt & Whitney Canada PT6 and GE Aviation Catalyst. So far, no airframer has signed up to the project, but Safran indicates that discussions are ongoing. Any production engine would be built "leveraging on the skills of European partners", it says. Safran will base the design on the Tech-TP demonstrator it is working on as part of the EU's CleanSky 2 programme, says the manufacturer. First ground runs of this engine, which uses an Ardiden 3 gas generator, will take place in the coming months, says Safran. CleanSky 2 presentations identify the Tech-TP programme as being aimed at the development of a new engine for "business aviation or short-range regional [turboprop]" applications. Key technologies identified for research include a small-sized core, advanced propeller, air inlet and gearbox. Safran is working with several partners on the project, including two sister divisions - transmission systems and aerostructures - that are major suppliers for the power and accessory gearbox, nacelle and air intake, as well as Germany's MT-Propeller.
