Re: Concorde time spent at max thrust with full reheat

I believe the maximum time in reheat was 15 minutes Is that limited by fuel tank capacity? Probably and perhaps an engine limitation, IIRC that was enough time to allow the acceleration from .95 at mid altitudes to 1.7 Mach around FL 450 after a steady accelerating cruise climb continuing at lower ...
