 | | 30 Sep 2007 11:10 AM | | 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. | | | "We have met the enemy, and they are ours!" -Commodore Oliver Hazard Perry | |

 | | 30 Sep 2007 12:42 PM | | 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. | | | There are 101 different types of people: those who understand binary, those who don't, and those who just can't count... | |

That is hillarious!!! How much air would such a system require? Would a 20oz do it or is more needed? | | Cheers,

 | | 30 Sep 2007 03:29 PM | | 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. | | | There are 101 different types of people: those who understand binary, those who don't, and those who just can't count... | |

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? | | | "We have met the enemy, and they are ours!" -Commodore Oliver Hazard Perry | |

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. | | | |

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. | | | |
