Hmmm "illegitimate" maybe you could be specific about which ideas and why? Please try to do some homework as many of the "ideas" i have presented...
If your familiar with that doc you know it basically says, if we ain't seen it before its going to take time! And were going to give it to the guy...
Possibly, but you can think even simpler! You should think of a sub like a surface boat in reverse e.g. the water containment walls extend from...
The inside of the concrete sub has a plastic bag (50%) half shell that will not be damaged by the collision and will retain the air pocket in the...
So when you boat is going zero speed relative to the water the water prop generates zero power / lift and therefore provides zero power to the...
All kidding Asside... This sounds cool... All kidding Asside... This sounds cool... At ~300kg it sounds like something I might be able get...
Hmmmm.... Sounds like a newt suit glider... Those actually work out well due to the very limited internal air volume (lungs) after you fill...
I have helped design a few drift gliders and i can tell you that limiting the dive depth to 120' is a big problem. It takes more "time" than that...
Two great posts Tom! I agree about the top 30'! For us divers I plan to have scuba on board but as a Volunteer SAR I can tell you the...
Trim Ballast Once we have an effective fast response 3D control system we need to address the long term "trim". Like an aircraft sub control...
Propulsion Propulsion and control systems on submaries run a wide gammit from albacore like subs with a single very large slow turning screw for...
I could have been a lot clearer! Tom you sound like you have a lot of experiance with "dive" related "issues". Any sugestions of other ways...
I tend to agree with your statement about US Build and quality control. Much of the cost of "New" designes is in the engineering and materials...
Great Numbers, Thanks! I agree with that! Safety and rescue systems on a sub, even when simple, are stil more complex and costly than on the...
1) Yes I am trying to jump start things with a few provocative seeds. 2) Yes I actually meant that the air entrapped in the sub would change...
Mydauphin, My regular sailboat "if you could call it that" uses composting toilets. You have to remove a "Bucket Size" tray once a month and...
Where should we have discussions about HULLs? I am inclined to start a thread outside concrete submarine since the goal is to evaluate Steel vs...
Mydauphin how would you relate the FIT out complexity of a >70 ton surface vessil with a 200T (<120' operating depth) sub providing a small...
