Do commercial aircraft go into supercruise?

Question

dude, chris. Supercruise means going into supersonic speeds WITHOUT the use of afterburners

Answer 1

If by "supercruise" you mean 1.0Mach+ without afterburner, the answer is no.  Supercruise is some of the very latest in turbofan engine technology, well alongside vectored thrust...

No commercial aircraft since Concorde is supersonic-capable.  There's no real financially sound reason for a 1.0Mach+ commercial jet, as the financial disaster that was Concorde decisively proved.

Answer 2

yes and NO, only one commercial aircraft (passenger aircraft) has ever traveled faster then the speed of sound; that is the Concorde. It cruised at Mach 2.0. Although it did not use afterburners when cruising, it was not classified as an aircraft with super-cruise; only due to the fact that the term super-cruise is new coined in the mid 1990's with the development of the F-22 Raptor as a marketing term. Most commercial aircraft travel at Mach 0.7 to 0.9; and due to noise and environmental problems they will not go faster any time soon.

Answer 3

Supercruise means travelling faster than Mach 1 (supersonic) without the use of afterburners.  Commercial jets cruise at Mach 0.80-0.85, so the answer is no.

Answer 4

No.

Only the Concorde can do this. However, it used afterburners in the 0.80-1.10 mach range because this region of speed is extremely turbulent and after experiments, it was concluded that using afterburners actually saves fuel because the aircraft spent less time in the turbulent speed region.

On a side note, I don't think any commerical aircraft today have afterburners.
