Turbines and Diesels On Separate Shafts
Sometimes the engine arrangement of diesel engine and gas turbine with each system using its own shafts and propellers is also called CODAG. Such installations avoid the use of a complicated switching gearbox but have some disadvantages compared to real CODAG systems:
- Since more propellers have to be used, they have to be smaller and thus less efficient.
- The propellers of the idling systems cause drag.

Famous quotes containing the words separate and/or shafts:
“A motionless still balance in the air, then parting, talons loosing,
Upward again on slow-firm pinions slanting, their separate diverse flight,
She hers, he his, pursuing.”
—Walt Whitman (1819–1892)
“Marriage has, for its share, usefulness, justice, honour, and constancy; a stale but more durable pleasure. Love is grounded on pleasure alone, and it is indeed more gratifying to the senses, keener and more acute; a pleasure stirred and kept alive by difficulties. There must be a sting and a smart in it. It ceases to be love if it has no shafts and no fire.”
—Michel de Montaigne (1533–1592)
