    So the pipe that feeds compressed air to the ballast tank to allow the sub to surface can get iced up if this "feature" is not controlled. Was that the problem with Thresher?

  • @lcl7wrkr
    @lcl7wrkr2 ай бұрын

    I've been trying my hand at designing a autonomous midget drone sub and have been reading a lot of Ulrich Gabler's writing on the subject...he designed the Type XXI sub during the war along with several other types, plus several post war designs...and Mr. Gabler indicates that the top vents should be placed as far back as possible when engineering the ballast tanks, or else the sub can dive at an awkward angle. He goes on to mention those slits at the bottom as a source of eddy currents between the pressure hull and outer hull, the energy creating those currents has to come from somewhere: your propulsion system. So a lot of care is usually taken in their design. Those valves connected to the "captain's flask" I think are shuttle valves...the act like normal hydraulic valves until you add pressurized air on the far side of the valve, which closes of the hydraulic input and shoots compressed air to whatever piston the hydraulic fluid was driving. Combat aircraft back in the day had a similar system in case the hydraulic lines were compromised or the engine driving the hydraulic pump was no longer running. It was a last ditch effort to lower the landing gear and flaps. Usually would result in the entire hydraulic system having to be purged a refilled later...better to have to do that than to write off an expensive plane!

    Great video, learned a lot :) Never would have guessed that a sub was so near zero bouyancy it could be hard getting one to submerge.. A question for you, or anyone who feel inclined to answer: What if the submarine submerges with say 10% of the ballast still being air, when it gets deeper I'm assuming that airpocket gets smaller and smaller as it gets compresssed, letting more water in and increasing weight. Can this lead to an uncontrolled dive? Or am I fundamentaly wrong?

  • @johncage5368

    Some questions (might be enough for a part 2, if you collect questions for a couple of days): 1. The obvious one first: If those are the "main" ballast tank there are obviously more. Do the others work on the same principle? 2. Are the main ballast tanks (or probably the others?) linked into pitch control? 3. How do you service these "have to be closed to the inside" tanks your life depends on? Is there some screwed close hatch to the inside or the top to do maintenance in port? 4. Good there are backup systems for the valves on the top. I assume there are also backup systems for the hatch on the top?, because if that stays open ... My guess (for 1 and 2) would be: Main ballast tanks only to get it perfectly balanced at your target depth with all controls zeroed and all the other ballast tanks and control surfaces to angle your boat however you want. BTW: Thanks for bringing back whi... bla.. whatever colored board. Really liked that series.

    Main ballast tanks are only flooded or not flooded. They do the bulk of the work to get the submarine to submerge/surface. Then you have multiple smaller trim tanks around the sub. These trim tanks are used to finetune buoyancy, and balance the pitch/roll. Then additional ballast tanks to compensate for the loss of weight when weapons are launched. As for servicing, I have no Idea, but I would suspect they are only really serviceable in drydock.

    On 688's, 637's and 594's you can access the MBT's through the grates on the bottom when you are inport. To do that your ships divers or divers from the repair facility go down and let themselves in. Then they do what ever needs being done in there. This brings up a whole discussion about subs and divers and safety and tagouts. Also I am not saying that the other boats don't have grates. I am saying I never touched a boomer or anything older than the Gato (except to take a tour on a museum ship).

    Fascinating. Subscribed. Do subs have plimsoll lines to ensure the ballast is correct before leaving port? Does the water slosh about in the tanks or is it full to the brim? If it can slosh then do they have baffles to quieten them? Why do they have trim tanks if you could potentially do it all with the main ballast tanks? Is trimming done automatically? Is everything the same in a double skinned sub?

    Very interesting, thanks for making the vid. But this leads to further questions about the compressed air and where it comes from. I assume there are multiple rotary screw compressors on board to replenish the ballast tank air tanks but where does the air come from? One cubic metre at multiple barr pressure inside the ballast air tanks would mean multiple cubic metres of uncompressed air to source the compressed air. Air would be at a premium in a sub I would assume and no one wants to work in a vacuum (literally). Big gulp at the surface?

  • @jhonbus
    @jhonbus2 ай бұрын

    It makes sense to me that you'd have a fixed opening at the bottom of the ballast tanks rather than a valve. There is no reason you'd ever want them closed. (I guess unless the whole sub is upside down, but I'd say you're already screwed if that's happened!) Being able to close off the tanks would mean they can be at a different pressure to the exterior which I'm guessing they are not designed to handle and they would either rupture or crush, depending on which direction the pressure differential goes.

    A couple of questions. With the drain grates are how do you keep the grates from making noise when the sun is underway. And you mentioned the ballasting of your boat, if the trim is that sensitive with full forward and aft tanks full, how do you account for the salinity of the water and when you are transitioning from high to low such as going into the Gulf Stream from the Caribbean Sea?

  • @MarkLawrenceKiefer

    @MarkLawrenceKiefer

    2 ай бұрын

    The grates are not loose, they are fastened to the ship so that they don't rattle, but are removable. Salinity changes is most common in the Arctic (ice freezing or melting). Temperature changes are more common (Gulf Stream, or depth). We have what are called Trim tanks that let us bring water in or out and move it around.

    I had a couple uncles that served on WWII subs. I've been on a couple old subs, not part of the crew. WWII grates had valves. When the valves were left open on the surface they called it riding the vents, It was for faster dives. I wonder if the design change from then to current subs had to do with the Thresher and Scorpion? With no grate valve, air pressure would have to be maintained on the surface. So what happens during fitting out and overhaul? Or mothballing?

    Did the USS Connecticut lose it's full front ballast compartment when it hit the undersea terrain? Looked like the whole front of the ship ripped off. I assume they were scared for their lives hoping the rear main blow would get them to the surface. Now to answer your question, torpedo tubes, the main sonar array, and maybe an anchor system? (runner up, some kind of concealed/retractable thruster?)

    Can you get rid of the lead weights off the submarine while submerged? The three things: * Heat exchangers * Watermaker intake (sort of) * Antennas

    Bottom ballast plates that offer some armor protection also would be much safer than lead weights. They could be remotely jettisoned in an emergency.

    Question: How air cylinders are refiled?

  • @ziggystardust4627
    @ziggystardust46272 ай бұрын

    When the tanks are blown at great depth (high pressure), are they blown until the water is completely driven from them, or just partially blown, and the air bubble allowed to expand as you go to shallower depth?

    Torpedo tubes, bow sonar and vertical launch tubes may go through/ be in the ballast tanks.

    So if a ballast tank gets damaged you can only control the water level in it down to the point of damage, right?

    To refill the compressed air for the ballast tank, does the submarine have an air compressor?

    3 things inside of a ballast tank that are not a part of the ballast system? If it's a 688i or newer then it be Torpedo tubes, Active sonar array, and VLS tubes.

    do the ballast tanks get grungy/ have barnacles from the sea water? how are they cleaned?

    I can't speak for now, because now may be different. But Subs go into overhaul (in a drydock) 2 or 3 times over their lives, but also go into drydock every few years for upkeep or repair. When they do this the hull get blasted clean and the tanks also get a good going over.

    Another idea for a discussion, most subs have forward and stern diveplanes, could you explain when each is used, are they always used in tandom, thx

    The bow plane are for main debth control. Stern planes mainly control the bubble or angle of the ship. At higher speeds, stern planes can control debth. Rudder is use to stear the boat and control the coarse.

    So, if a sub is upside down or on its side, it can't blow ballast to surface since the air would just escape through the grill, yes?
