[PSUBS-MAILIST] Composite pressure hull?

[Bob Duncan <katsurencho@yahoo.com>]

I'm afraid i probably won't be ready to start the design of my own submarine for another year.

Alvin the deep sea research submarine designed by Al Vine of Woods Hole Institute uses a titanium pressure hull.

I have an intrest in designing a similar pressure hull, but using a relatively thin sheet or layer, of pure aluminum (1100 alloy), and wraping it with layers of roven woven (fiberglass cloth), and using epoxy resin. Which has been used in the marine industry for years.

High pressure gas containers (both sphere and cylinders), have been around for years. They hold an internal pressure of 10,000 psi (working pressure). I would think this would be very feasible for an even higher external pressure.

The areas of concern are the places where electric or hydraulic connections go thru the pressure hull.

Two guiding principles govern Israel Naval Commando doctrine:

1.Every defense system is vulnerable.

2.The enemy can deal with weapons and operational methods that are known; for that reason, naval commandos use imagination, daring and initiative, to create situations which cannot be anticipated.
