Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

Then Stian had the counter-rotating concept, and that's where it matched up. An integrated turbine where the generator is part of the solution, not part of the problem. Hans: Tilting, floating ...

Late last year, Safran completed a ground-test campaign with a full-scale counter-rotating open rotor (CROR) engine on an impressive outdoor testbed, almost 10 years after the launch of the ...

POSITAL’s Multiturn Counter Module is a zero-maintenance rotation counter designed to be integrated into motors or other types of rotating machinery to provide their control systems with a reliable ...

Safran Aircraft Engines now has clearly plotted the technological trajectory a counter-rotating open-rotor (CROR) engine can be part of, somewhere between an ultra-high-bypass-ratio (UHBR) turbofan ...
