Now we’re talkin’. None of that namby-pamby six million pound thrust childs play anymore; a rocket engine that a man can respect.
The L-24 AH used four of the turbopumps used by the individual 6-million pound thrust L-6H hydrogen/oxygen engines. Chamber pressure was 2000 psi and the expansion ratio was 40. This engine used a toroidal combustion chamber wrapped around a central “plug,” much like an aerospike engine, but with an external bell wrapped around everything.
