Vulnerability?

Is the Pleuger rudder as vulnerable as the Bowater link implies? has it sufficient power to propel the ship without the main engine running? Expert help is needed on that part of the topic. Fiddle Faddle 23:03, 30 April 2006 (UTC)[reply]

I can't answer the vulnerability question, but I can answer the question about Pleuger rudders being able to move a ship without the main engine running. Keep in mind that marine engines are not high horsepower engines, the way one might think they'd need to be to move something the size of a ship. Many tugboat engines, such as the Detroit Diesel 12V71N, produce only a few hundred horsepower, but very large amounts of torque. Torque is going to determine the ability to turn the boat's screw, or in this case, the screw on the Pleuger rudder. My recollection is that the Pleuger rudder motor is on the order of 125 horsepower, which assuming lower RPMs for peak horsepower (see the section on the relationship between horsepower and torque) should be enough torque to turn the propeller on the Pleuger rudder and move the ship.

If you can figure out how to put all that information into this article, have at it. If you need still more help, drop me a note. Tall Girl 12:32, 20 May 2006 (UTC)[reply]

So ... are we happy now? -- Tall Girl 22:17, 25 May 2006 (UTC)[reply]

Happy :) Fiddle Faddle 22:38, 25 May 2006 (UTC)[reply]

Cool beans! I can't think of much of anything else this page needs, so I'm going to remove the tag looking for an expert. If anyone can think of any additional research that needs to be done, put a note on my user page. -- Tall Girl 19:03, 26 May 2006 (UTC)[reply]

The pleuger rudder is meant to be assisting in the fast maneuverability of ships, in tight harbor operations. Thus,it is only an improvement of rudder by controlling the water flow pattern passing a rudder and thus giving it an artificial flow and thus an extra power to steer even in slow engine r.p.m.  It is absolutely not a substitute of propeller, without which, the mammoth energy required to make a ship move over water  is hard to generate.(http://sailors-club.com/wikishipping/index.php/PLEUGER_RUDDER)  —Preceding unsigned comment added by 117.200.144.238 (talk) 17:56, 17 October 2010 (UTC)[reply]

On the subject of horsepower vs torque, Tallgirl is absolutely correct, as horsepower isn't a real and direct measurement, it is a calculation from measurable variables. — Preceding unsigned comment added by 209.210.20.2 (talk) 21:11, 16 July 2011 (UTC)[reply]

Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request it's removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

Below is a list of links that were found on the main page:

Resolved This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.—^{cyberbot II}_{Talk to my owner:Online} 00:08, 4 July 2015 (UTC)[reply]
