[PSUBS-MAILIST] dive plane

[via Personal_Submersibles]

Hank,


The Delta dive plane was moved up for three reasons. 1-to keep it from getting beat up on the surface, 2-to get it out of the pilot's line of sight, and 3-to have more room and make it bigger. It definitely works better.


As a side note, the control lever/penetration arrangement is exactly the same on Delta, with the only real difference being the angle of attack and the upward swept extension rod to the dive plane lever. It's a fix you could do, and might save you having to fool around with thrusters.


Then again, if you are going to be messing around with wrecks...well, fine adjustments at slow and no speed are a  very good thing in my experience.

Tim,
There is one dive plane mounted at the top of the hull just behind the arm.  In 
the fourth picture you posted from the convention you can see the mount just 
above and behind the top of the arm.  There is a rod extending from under the 
deck that controls the plane. The dive plane is smaller than the one on Delta 
and also smaller than the original on Gamma.

 Hank,
 
 This does make sense, control surfaces must
 have water flowing over them (or
 attached
 thrusters) to do anything.  Thrusters alone would work
 unless you
 are gliding the sub up or down,
 then dive planes would do the trick. Would
 you upload a photo or two so that we can see
 how they are installed?

 Big dive day today revealed
 that the dive plane on Gamma is not very
 effective.  It takes a lot of speed to work,
 makes sense.  I am thinking a
 thruster at
 the end of the dive plane might be beneficial.  I am
 planning a
 dive next weekend to look at the
 Anscomb ferry that sank in Kootenay lake.
 The bottom of the ship is about 200 feet or a
 bit less maybe. 
 Onward and downward.
 Hank
