Planing hull submarine possible? (Closed)
Ok so If I am not mistaken the submarines that are for sale are planing hull submarines AKA they do not use propellers on the keel as normal in game submarines might... There must be a trick to balancing and water flow around different shaped hulls if anyone has any ideas about this then I would love to hear them.
Answer from: Teodor90
Think of the water as air. It behaves similarly. if a 1-2hull would push air down it will do the same with water. REMEMBER: ACTION = REACTION. that means the hull i was talking about will push water down but it will push you up. Also density is important. Get it close to 1

Thank you for the reply tedor09 I will give you a brief rundown of my submarine that I currently am building it is 150m length 15m beam and4 blocks tall it has two small boilers on it that are placed horizontal within the hull using the 360Â° glitch. It is exactly 1.0 dencity only the slightest bit of the top is showing out of water. Now the problem is that no matter how many 1/2 huls or 1/2 armor or 1/2 ballast I put on it doesn't seem to make it a planing hull... The dencity obviously changes and the area with the 1/2 block sits either higher or lower in the water but there is no noticable effect of water flowing over the block and pushing the boat down... (Ex: when you turn with a rudder there is a highly noticable change in direction where when I use the 1/2 block it seems to change no other variable than dencity) yet again your comments are much aprecieated

If you have seen plane flaps during landing try and imagine those. now think that they push air down, giving the plane lift. put that wing upside down and it should do the opposite. example: buy the uboat. Try it. it will go under easily. now delete the 2 fins at the front and try it again. it wont go down or it will go slowly. and you said that if you use 1/2 blocks to turn nothing happens. try putting that block at the very back and make the wedge larger. now try. it should go the way you want. the idea is that if you put the inverted wing at the middle you wont probably notice. put it at the front and it should push the front down when moving. propellor placement is important. put the props higher than the middle and they should make the sub pitch towards the front slightly while moving. anyways, to summarize this in one word EXPERIMENT. You will find a good design. PS: try some ballast too.
Now go to a door. push it from the doorknob. its easy right? now push with your hands near to the hinges. its much harder. Thats because of this F=f*d Where f is the force you apply. d is the distance to rotation point which is usually half the total distance. F is the resulting force. So lets say i push your sub from the front with a force of 10 newtons. (pushing it down) 10*75=750 ... Thats a lot. if we push it from closer to the middle we get a smaller force.therefore less effect. Teodor90.. Employing physics in gaming.Since 1862.

Still for some reason can not seem to get this to work I wish someone could make a YouTube video on how to make a decent submarine you know 50+ kys submerged planing hull balancing etc... Unlike the silly videos on there right now where it's basically a sinking box with s*** loads of propellers...
Answer from: Teodor90
I made i sub using armor free and it it a box. but it makes up for the looks by using its weps. it doesnt matter if your sub is a box. if you can make a torpedo wall in 1 tap and your sub sinks then consider it a good design. also read the sub usage manual posted by me. most effective when having few torp tubes
