[PSUBS-MAILIST] Dart 37 diesel electric concept drawings...

[lawrie-psubs@environics.com.au]

GoodyaDay to all,

Like the idea of those light weight batteries.  Have you also seen the 
development of flexible solar panels, some are so flexible that you can 
wrap them around a mast.

The Dart project, heres the concept...

The mid-ship section has a large bounancy section that when surfaced 
doubles as a accessway between the pilot/crew pods and the aft engine 
room.

Have the new drawings on the home page www.psubs.engineer.net.au

I have desiged it in such a way that linkages between controls and 
planes and rudder are mechanical.

Reasonable freeboard, may need some wave deflection foward of the 
mid-ship viewport.  Perhaps something that can fold away when submerged.

Also a snokel arrangement which is isolated from within the mid-ship 
bounancy compartment.

For trim, two oil tanks fwd and aft with a 2-way pump.

Looking closely at the diesel/electic arrangement i.e. one diesel and 
generator + compressor, two permanent magnet motors, and two battery 
pods, one for each electric motor.

Drop weight, still working on two idea.  One drop a section of the keel 
directly below CofG, or have two rails that all cannon balls of steel 
roll out from the bow the stern.  Only problem with the second option is 
if your in a nose down attitude when you need to drop weight.  I figure 
that all the components that could possibly result in a leak are astern 
to the midship pilot pod. Thus a leak results in stern down.  Hope that 
makes sense.

Anyway comments and ideas always welcomed.

Cheers,

Lawrie.
