Anti-Ship mines that do damage to the ship

Sounds like a good anti shipping weapon. Might be able to tow it and anchor it off into the convoy lanes. Could have a fairly long anchor line so it allows it to drift and not just float in one specific area so its location changes.

 

good thinking rusty!

 

Just make sure you don't tow it too fast or you might trigger it.

 

It will give the option of slower ships to tow the weapon. Either that or it will make it more of a challenge since weapons misfired on occasion during war.

 

wait, didn't you say that you could arm it with a radio? if thats the case just done arm it until its in position. Secondarily... if you are anchoring it you might need a person walk it out.... or throw it.

 

Well I don't have PowerPoint so I cannot view the file, but from what everyone is saying, I can assume that this "mine" is a self-contained floating cannon unit. I have thought about this before, and came up with a potentially very effective design based on advanced Big Gun weapons technology. Each "mine" would consist of a Big Gun cannon, in particular the negative-pressure Cannister cannon (I can share details on that design later). It would have 4 or 8 barrels, spread out in a 360* circle around the cannon, loaded with two 1/4" balls per barrel. For triggering, it would require a remote signal to arm the firing mechanism, then several clippard whisker valves would trigger the system when a ship got too close. They would be deployed in a series of 8-10 mines, to defend shore batteries, disrupt convoy routes, and simply deny areas to fighting ships.

I have also heard of another possibility, that does not require extensive machining and manufacturing to produce a useful anti-ship weapon. Do you know what happens when a bubble of air rises beneath a ship? For the moment that that bubble is in contact with the ship, the ship drops a little because that part is no longer displacing water. Fill the water around a ship with bubbles, and it will drop like a rock until the bubbles stop. Throw in the turbulence involved with a massive release of bubbles, and there is a very significant possibility of capsizing the target ship. There are several possible ways to create a sudden, large influx of cannons in a "mined" area. The first is to use a large tank of pressurized air, an ultra-high-flow valve, and several pipes leading to the target area. The second is to pipe the vent of a vacuum cleaner to the area you want to blast, and turn it on.

 

Recreating the Bermuda Triangle! You are evil!!!!

That is hillarious!!!

How much air would such a system require? Would a 20oz do it or is more needed?

 

I was actually thinking more like a large compressor with one of those huge 30-gallon air tanks. In order to be effective, you've got to put out a tremendous amount of air in a very short time, over a reasonably large area. Suddenly and rapidly venting 30 gallons (volume) of air, at 50 PSI or so, would hopefully do the trick. I did an experiment several years ago, involving a MAT-2 and MJV-2 valve underwater, and just that little bit could probably capsize anything smaller than two feet long. Bigger ships would require significantly more, and if they have a good deck seal then you're even less likely to have success.

hey Carl,

I like your idea about the bubbles simulating an underwater minefield..... its not only cheap but relatively easy to do to.

Anthony has submitted a short writeup for the Scuttlebutt about his mine, would you like to submit a short writeup on your idea?

 

With a grid of pipes you could cover a good bit of area.
A pain to set up but really fun to execute.

 

There needs to be a big gun variation eventually.

 

I would think you would have to use big gun sized shot to get it to travel any distance. A bb won't penetrate the water any distance at all. Not that it really matters with a contact switch.

 

Well, I hope to have a prototype ready for the NYBG battle on 10/13, but thats pretty tight. If so, I'll see if someone will let me test it on their ship.

 

do you have any pictures or can you send me the power point file?

 

Go to the file manager on the rcnavalcombat.com home page and select donanton.

 

Actually the bb would only travel through around 1/4 to 1/8 of an inch of water before hitting the ship.



No progress yet. Too much architectural class homework.

 

What kind of solenoid valves do you guys use? I've heard about "clippard" valves.

Thanks,
Anthony

 

Clippard is a brand of miniature pneumatic parts, not a particular valve. Clippard Minimatic makes is the company that makes the poppets (MAV, SMAV, MJV), actuators (MPA), and air fittings and hose most commonly used in model warship combat. One of their pneumatic products is a solenoid valve. website: www.clippard.com

 

What if the ship goes down, but when you turn the air off the ship rises back up? It also raises the problem of ships returning to the surface upside down. And staying like that.

Yes I am still going to build my mine.
