Hello everyone,
Doing some thinking lately. I would like to try building a space-plane launch stack using only solid boosters. Naturally this would have to be somewhat asymmetrical, due to the demands of properly placing a spaceplanes CG onto the stack.
My original idea was somewhat like this:
But as you can see, the centers of thrust and mass are misaligned, perhaps heavily.
So the obvious solution is...
But does that really work? Offset propellant tanks & engines are fairly trivial with liquid fuels, since all you really need is some pipes. With an SRB though, would it be possible to constrain the exhaust exit from the larger diameter of the propellant casing, or would this shape be prone to rupturing on the side opposite the exhaust exit?
