Concorde Orange/Brown Exhaust?

Sun Mar 03, 2002 2:39 am

I've watched the Concorde take-off twice now and the exhaust appeared orange or brown.

Am I seing things?

Is this the result of the four afterburners or just cheap jet fuel?  Wink/being sarcastic

The Concorde doesn't use afterburners during take-off.

What you are seeing are the Concorde's old smoky engines in action.  Smile

...ah yeah, they do use afterburners.

Read-up on them.

It's the afterburners, AND the engines as well...they're extremely noisy and dirty, but sound really cool.

I've seen footage of the TU-144 taking off, and it has the same orange-brown exhaust as the Concorde. I would assume this is from the afterburners, as well as the engines themselves, which to be sure, are of a FAR different type used on any other airliner!

It's from the afterburners, and Concorde is exempt from noise regs due to it's tiny fleet.
Along with the noise-abatement procedures on t/o, (15% engine throttle-back and when required, avoiding populated areas-as happens after t/o from JFK).
Also Concorde has limits on the times it can operate out of airports.
Actually the noise abatement procedures are what beat the movement to keep it out of JFK, and other noisey jets around in the late 70's, such as 707's, also adopted a similar procedure.
At first the anti-Concorde lobby said Concorde had 'cheated', but shut up when other noisey aircraft reduced their noise too.
