Compare weight of a fixed bell expansion nozzle
and a variable geometry expansion nozzle
that covers the the sired expansion range.
Would't you be better of with a large diameter circular
aerospike engine
that hides behind its heatshield cum plug nozzle center?
You would, if you could be assured the trans-sonic performance of the
aerospike engine would be good enough to allow your vehicle to reach orbit.
Static performance and vacuum performance of aerospike engines are well
understood. Performance in trans-sonic airflow is still less so, as
it's very difficult to test that without actually flying a test vehicle
through that speed regime. And after all these years, still nobody has
done that (that I know of.)
