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 From:

Jeffries 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 Resepectfully, Jay

do. Approximations gratefully accepted. Would be helpful. 2 sq ft, 6 sq ft? approx
length and breadth. Hugh
