The experimental sub USS Albacore (AGSS-569) was the first US Navy sub built with the now-common teardrop streamlined shape....
The early boomers which carried Polaris missiles were attack boats which were stretched by adding the missile compartment aft of the sail, in...
In the older submarines, like the US Fleet boats of WWII, there was a small pressure chamber built inside the sail, which chamber was separate...
The speed of the engine where minimum fuel consumption occurs and the speed where max. HP is produced are pretty much two different things....
The parlance, like the vessel with which it is associated, has evolved over time: https://en.wikipedia.org/wiki/Sail_%28submarine%29
Yes, they do. The big sticky up thing with the periscopes and whatnot is called a 'sail': [IMG]
It's not clear which class society you were having this argument with, nor are the particulars of this argument clearly defined. In general,...
In the context of a propulsion system, torque is not a static load. It varies, depending on several factors, including engine RPM. The propeller...
Pot-ay-toe, Po-tah-toe Torque and power are two sides of the same coin: what the engine does while it's working. I'm bi-lingual, so I have...
The use of a gearbox doesn't change the power output, except by a few percent for friction losses in the gearbox itself. Essentially, power in...
The point is, for the same installed power, you could have two different torque outputs, depending on which engine is selected. You have to...
P = T*N/5252 where P - power output in HP T - torque in ft-lbs N - RPM Propellers convert the torque of the engine (as modified by any...
I think the US EPA and the environmental authorities of the several states would strongly disagree with your opinion that urine can be discharged...
The El Faro was in the Jones Act trade, that is, its primary route of operation took it between ports located in the mainland US and Puerto Rico,...
That's an interesting river tank barge tow you have. On the Mississippi, tank barge tows are designed sometimes using four barges, but they are...
It's one thing when a ship goes aground at a large list; it's quite another when the ship remains floating in a storm, where the waves cause it to...
Since US towboats are not really engineered in a real sense as you understand it (more like a craft tradition where a new boat copies the...
I must confess, I haven't kept up with Rabah's explanations for his design, except to say he seems to be designing an inland tug, at least, what...
All you have to do is Google "Push boats" and you'll get pictures of all kinds of push boats operating on US waterways. These include the small...
In general, no. There are a lot of single-screw merchant ships out there. When I was in school, I sailed on one, a later model Mariner-class...
