"Was it so much worse than that of regular jet?"
I remember spending a lot of time at Heathrow in the BA departure lounge waiting for flights to Edinburgh - normally you couldn't hear very much (if anything) from outside. Then the whole place would shake and you'd hear an impressive roar from outside and you'd know a Concorde had taken off.
- NeedMoreTea 8y agoConcorde was only louder than the rest on takeoff and initial climb out - because the reheat was on. Reheat is stupidly loud. Reheat was needed as it was optimised for super cruise (sustained supersonic) - something even fighters aren't, which made it very inefficient at takeoff speeds. On approach and cruise it wasn't that much different from other jets of the era. Modern engines could be far quieter and not need reheat for takeoff.
