Departure without noise or boom considerations
Just for theories sake, if there were no noise, speed or boom considerations what would be the optimum profile for Concorde to fly after departure ?
In normal service I understand it had to comply with normal noise abatement departures, speed limits and remain subsonic until far enough from land to prevent the boom being a consideration.
But what if it could accelerate immediately, with no restrictions of any kind ?
I imagine you would stay in afterburner, accelerate to VMO and on to M2 in the climb ? or would airframe heating at lower altitudes prevent this ?
Lastly, was this ever done in testing, or for example leaving Barbados ?
