Re: [PSUBS-MAILIST] Re: Increasing pressure inside hull
Jay,
Increasing pressure is done in case of an emergency escape from a sub. In
the Busby book page 660 - 665 you can read more about it. It isn't fun. I
doubt if you need to increase pressure in case of a leak. I suppose in most
cases leaks are limmited to water seaping through seals. In other cases you
won't have time to react (crushing viewports, or a pressurehull buckling).
So I don't think it is worth while making a safety system like you discribe.
