Re: [PSUBS-MAILIST] Thruster ideas

["Lil Brother LLC" <lil_brother_llc@bellsouth.net>]

Well,

It didn't take long....and I've run into a snag.

Here is the problem....and I would like opinions of the best choice....and 
it is a choice.

Props are optimized to thrust in one direction. Which direction would be the 
best for thrusters?

I figure forward for a horizontal thruster.....what about a vertical one?

My thinking is ofcourse thrusting (pushing water) down.....giving you an 
upward movement.

This discussion is for fixed thrusters not movable ones. Movable would be 
optimum, but life doesn't always work that way.

If anyone disagrees please let your ideas be known,

I'm working on some ideas....and would like to know how many people would be
interested in the design.

The thrusters will probably start off small, but they should be the
following (pending research):

1. Approximately the thrust of the ones used on the K-350.

2. Magnetically coupled shaft (reduced shaft pressure)

3. Oil filled. (Greater depth capacity) I know some oils that I believe can
be used that are not environmentally hazardous.

4. Phased type motors, so the controls will be more complex.

Let me know your thoughts,
