Hi, Joe and All . . .
Regarding tying in your planes together. You
may want to consider the rationale for keeping them separate in the military
boats: The aft planes are used for depth keeping and the forward ones for trim
(hell, maybe it's the other way around).
In any case it may very well turn out to be more
practical to do as you say and just tie them in together. We'll find out
soon enough.

Joe,
I'm using the same type of system on my sub, I have a sitck and rudder
arrangement like on an airplane. I have foot pedals that contol opposing
side " ailerons" which turn in the opposite directions for banked turns.
The stick controls the rear rudder, which is a side to side motion on the
stick, and for accending or decending the stick is pushed forward ( for down)
and back ( for up ). This is what I have been working on for the
last few weeks on my to scale mock up. Everything is pretty straight
forward linkage, however the side to side motion on the stick, for rudder
control are miter gears so I can change that motion perpendicularly. An
on one of the foot pedals I needed to use two meshing gears to reverse the
motion with a counter shaft, so I could get a better angle (leverage) on the
pedal. All these motions are turning thru hull shafts in a rotating
manner.
Regards
Brian

Subject: [PSUBS-MAILIST] Dive Plane
Mechanical Linkages
Since my boat as designed is primarily a snorkel boat on the
tiny diesel, dynamic flow over dive planes is critical to control.
I have in mind a mechanical linkage system similar to
aircraft control surfaces with either a bell crank and pulley system or
better yet a pushrod and torque tube system.
Individual control of the bow and stern planes as in the WWII
boats is not really practical, so I am planning on an interconnection
via either a single lever or a side mounted wheel. Very simple stuff, no
hydraulics or electric motors.
I welcome comments and suggestions as every time I put
something out, my design is improved tremendously as a result of the
input.
Thanks
Joe
