- No one has mentioned using a cylinder of aluminum with perhaps a star
- shaped core and spraying LOX down it. The aluminum is both the fuel
- and structure. Running it until much before burn through is probably a
- bad idea, but it may be cheaper than importing steel shells from earth.
-
- Doing casting in an unknown enviroment with bulky molds could be a
- problem. Instead it might be possible to build up a cylinder from
- a lightweight aluminum frame on the moon in layers by either aluminum
- liquid or vapor. Oxygen tanks might be made this way as well.
-
- I guess this would be a solid/liquid hybrid motor of which I have heard
- little about. Are there serious problems with hybrid motors or with
- what I've outlined above?
