Re: [PSUBS-MAILIST] Hey, looky, rocket fuel as ballast!

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

Dewey,

I looked for you in the book '"rocket propulsion elements"from G. Sutton,
what is the bible for rocket engines
He spend a few pages about this subject . In short:
-burn time: 30-300 sec
-temp 800-1600 K
- can be used in steel casings
There is mentioned a variaty of uses from car airbags to (yes, underwater
application) drive missiles out of a submarine.

Seems to me there is a lot of research needed to get it reliable . Isnt
exist a chemical what yust produces gas in contact with water?

regards, Emile
