[edit] Ship Efficiency
"Controllable pitch propellers or CPP for marine propulsion systems have been designed to give the highest propulsive efficiency for any speed, at any loading condition ... By controlling the pitch of the blades, the optimum efficiency can be obtained and fuel can be saved." This is in direct contrast to; "at full power a fixed propeller will have a slighter better efficiency then a CPP."
How is it that Controllable Pitch Propellors can be more efficient in terms of power and fuel, whilst being less efficient that fixed pitch propellors? What is the difference at "full power"? Kirby Rourke 09:17, 20 June 2006 (UTC)
