On 11/11/2021 18:36, Henry Spencer quoted John Carmack:
"Since we can demonstrably
do a TSTO, launch assist only makes any sense if you are assisting a
SSTO vehicle.
disagree - how about the common zeroeth rocket boosters in eg Ariane etc?
[Merely] improving performance by some fraction by adding
some capital and complexity intensive additional system is almost
certainly a losing proposition."
Yep - if the second stage was a cheap (fsvo "cheap") solid it might make
some sense (a bit like a 2-1/2 stager), saving the cost and complexity
of the "first" stage liquid engines - - especially as you could use the
necessarily strong aerodynamic case as a motor case, rather than just
throwing it away.
