Re: [PSUBS-MAILIST] Dive planes



Hi David, I've got to add a bit here.
The Poor Knights was rated by Jaques Cousteau as one of the top ten dive sites in the world.
Keith Gordon is in the Psub group & wrote a book on the Niagra wich I'm half way through. (great stuff)

Hugh,
 
  I will continue working on our hybrid hydrophone to work out any kinks. 200 meters is over 600 feet deep! It must be able to travel this far down and reliably perform once there. No matter how many times its needed.
 
  I am not familiar of the wreck of the Niagara. Enlighten me, and pray tell, where is Tutukaka? Is this in the salty sea?

Hi David,

There is only a depth sounder  on board and it needs a passive Sonar of some sort so I want to fit that microphone to it.  Would be good to have something. I am wanting to get it out from Tutukaka and dive on the Niagara with a bit of help from Keith Gordon who is the resident expert on the wreck and wrote a book on it.  He has got some sort of rights to it as there is still some gold on board.  I will be triying it out somewhere safer first though.  Have to have dreams.  I’ll be in touch on the build though.  Count on it.   Hugh

Hugh,
 
  Very good submarine! It seems as if you have more room than a standard psub. Well kept. I like your angle indicators...just aquired one simular.
  Once operational, where do you ihtend to get her wet?
  Any sonar be it passive or active aboard? Ever thought of building one? I can help.

Jay ‘n’ Vance. 

Thks that is helpful stuff.   I was thinking of putting some planes on the Comsub.  It has had a rudder retrofitted about 12” x 24” high but it is in the prop wash.  I am just reconnecting the aft lateral thruster and reconditioning all the hydraulics.  AThe hydraulic pump is really noisy so I’m thinking of putting a pulse suppressor on and a 5 litre accumulator with a pressure switch.  Otherwise I think it will drive me nuts.  I want to go down for some peace and quiet. 

 

I have uploaded a few photos of the internals and bits on the projects page under “Hugh Fulton”   Comsub.

 

Regards, Hugh

Hugh,

I am still working on my presentation for the upcoming Conference and need to figure the various increases in size for the control surfaces for the Seehunde.  Just remember in the back of my mind the large tail surfaces on some Perry submersibles...I may be wrong but it just sticks in the back on my mind.  Some of the images in Busby’s Manned Submersibles might be of assistance.

 

After writing the previous email and recollecting on the classes I attended over lunch while at Electric Boat, for larger Navy subs that have the capability to operate at higher speeds, the control surfaces are relatively small when compared to the size of a hull (effectiveness of control surfaces goes up with speed).  The minimum effective speed for these surfaces was 3 knots.  For a PSUB, the control surfaces are larger in area compared to hull size so may be more effective.  Unfortunately for us, there is very little in the way of published naval architecture references for submersible design and even less for subs the size of the typical PSUB.

R/Jay

For the uninitiated what size were they?  Mm or inches will do. Approximations gratefully accepted.

Would be helpful.  2 sq ft,  6 sq ft?  approx length and breadth.  Hugh
