[SS-Propellant] Propellant casting schemes

[Rich Nakka]

Greetings, fellow Propellant Development Team (PDT)  members,

I am sure you have all been closely following the interesting 
discussions about proposed propellant casting schemes.

I've summarized the schemes in the following Word document:
http://sugarshot.org/downloads/ssts_propellant-schemes.doc

I would appreciate if each PDT member could read over the document and 
make comments including pro's and con's of the various schemes. Once 
comments  has been compiled, we can then take the next steps in 
assessing the schemes and trying to narrow down one or two that we can 
invest more effort in studying greater detail.

Please return marked up docs to me by Wed. Dec.21st evening, at the 
latest. I will be gone on vacation after that and I plan on taking the 
feedback with me, to peruse and summarize, while on holiday.

cheers & thanks
Richard
