On: Autophage rocket engine consumes plastic fuselage ...

[rkagerer]

Is the idea that in a vertical version of this the motive force pushing the stack into the nozzle would be provided from the rocket's own acceleration?

Would that negate some of the controlability characteristics?

And would it need to be carefully tuned to the launch profile? (I assume deviations wouldn't be self-correcting eg. if acceleration is reduced there's less injection force presumably leading to less thrust).

You could probably put some low effort cables from the engine to the top of the stack and add pressure as needed without too much effort
