The<br> idea with a<br> conical bearing face on a hatch,<br> if you are not trying to establish a<br> metal-to-metal seal, is to provide a load path<br> through the hatch itself<br> to carry the shell<br> stress that would otherwise require heavy<br> reinforcement around the hole. Thus, the<br> "ideal" hatch would be the<br> same<br> thickness and curvature as the shell it is replacing,<br> aligned to it<br> so the load transfers straight<br> through, with a flange on both the hatch<br> and<br> shell parts to create a substantial bearing face. The<br> conical angle<br> in that case would be set by<br> the hatch diameter, as the ideal interface<br> angle would be perpendicular to the shell at<br> every point. I suspect<br> that in<br> practice, the cone is exaggerated beyond that, because<br> we're<br> talking about very small angles on<br> larger spheres - on a PSub, perhaps<br> it is<br> more important. The other advantage is of course the<br> self-centering.<br> <br> Sean<br> <br> <br> On 2015-11-07<br> 16:26, hank pronk via Personal_Submersibles wrote:<br> > Dr Nuytten thinks he has detail drawings<br> that he is willing to share<br> > with me, if<br> he can not find them, he has given me permission to<br> measure<br> > one of his Pisces in the bone<br> yard.
