Hi Rick.
Remember those little toy submarines that we used
to put baking soda into to make them rise again? Perhaps you
could have a canister of baking soda that in an
emergency could be exposed to the water so it would
expand, create gas and fill your ballast tank. Sounds a bit safer than a rocket
to do the same thing.
Bill.

Subject: [PSUBS-MAILIST] rocket
fuel
guys
today is rocket day and will
be luanching a 15 lb v2 copy expect to reach an altitude of 6000 ft. i know
this is off subject but i remember the sub that used rocket motors for a gas
generator for the emergency ballast. i was wondering if anyone did pressure
study on rocket motors to see if they were stable under pressure. my thought
is that they are self oxidizing and desinged around an internal pressure of
about 200 lbs. while external pressure should not mater in the combustion, i
have seen enough of these thing go boom that i would like to see some testing
before using. the report from the guy that used this system from a shallow
depth was that it was deafening.
