Hijack (split from Idea for a rocket engine)

Seems to be an overlooked problem.

Rockets are meant to operate in "0G". Sort of.

There are solutions to this problem not present in your design. The only thing keeping everything downstream in your design is gravity itself.

The opposite, really. Rockets to escape gravity. Thrusters to move and navigate once you’re more or less clear.

Well I am grossly generalizing but there is zero need for reuse of a rocket fuel on Earth. 

And fuel is a relatively low cost for LEO.

So the implication is its use is for deeper space missions. 

The SCS only ingnitioned in a near 0G environment which is why it was important for the SCS to first Ullage before firing.

You’re also grossly off topic

How? The rocket engine needs to fire in 0g environment and has no operation for ullage.

That's specifically on topic
