Descending at 11,000 ft/sec is possible but very unlikely, especially with Concorde 
IRL it would mean grounding the aircraft afterwards and basically discarding of her...... no airframe as of yet is able to withstand such descends at a
normal interval.
As Joey has posted above, you descent at T/D, which is (in Concordes case) pretty far out. To not stress your pax and airframe, I agree on Joeys
3000 fps but no more then 3500 fps
I gives you in Concorde an angle of 10-15 degrees down depending on speed.
The 11,000 fps decent mentioned is a last resort maximum for the airframe
say you are cruising at 45,000 ft and a window cracks.... you have
about 3 minutes before unconciousness and 4 minutes to descent to 10,000 ft before your pax start to die..... thats where the 11,000 fps comes from
as stated in the development and building documents. Still, 11,000 fps means you are going down at an almost 60 degree angle...... eath is closer
then you may think
A Concorde having done an 11,000 fps decent on my fleet is a complete write-off and will be sold for scrap
I fully agree with Joey here
