RE: [PSUBS-MAILIST] ambient ballast control

Rick,

My mistake. I was not clear in communicating what is on my mind.

Here it is     http://www.frappr.com/?a=viewphoto&id=269116&pid=1450694

As for cost, this submarine building stuff for any of us is equivelant to climbing Everest. The risks and opportunity costs are nearly the same, with the return on investment being exactly equal , simply....personal satisfaction.

Nothing stupid about it.

I appreciate the effort

Joe

hi joe.

 

    i have given your design some thought which means this post will probably be really!! stupid. 

 

    design constrants

 

    ambient design = the stuff will get wet/ electric is bad or expensive

    minimixe free surface area in ballast tanks = no water sloshing around in the     tanks on the surface.

    cheap = not everyone hit the lotto last night

    dependable = we don't want to die, just are friends think so.

 

flood valves use a flapper design with a rod throught the flapper held with a spring to act as a overpressure relief valve. mount the hinge on the rear so water flow will hold open incase of failure. control system manual psuh pull rod and bell cranks to single lever, the relief springs will help with the rigging here to rods will not have to be exact. just like the overe presuazation valve one a boeing but the spring will be on the outside not the inside with the controll rod going through the flapper.

 

vent valves and blow valves

    run your vents to the sail you can use pvc pipe due to low pressure and mount ball valves there.
