[PSUBS-MAILIST] endcap/bulkhead question

["Emile" <2stroke@hetnet.nl>]

Hello all,

 

For my future psub I consider an inverted endcap or bulkhead

See the "drawing"of the pressure part.

At this configuration the sphere shelfs only have a tension loading what is preferrable.

I lookt at almost every psub design on the site but no other sub has this configuration, exept for the Spurdog.

Am I wrong in my toughts and are there high stresses in the sharp transition from the sphere shelf to the circular hull??

 

hope someboy knows,
