Forgive me if this has been covered before but did the Concorde have bleed air wing or fin Anti-Icing ?
The engine intake guide vanes were heated [on selection] by a hot air bleed from the exit of the HP compressor. Other than that there was not hot air bleed for anti icing purposes
Now the leading edges of the intakes and the leading edges of various bits within the intake along with the underside of the wing in front of the the intakes were deiced by a combination of continuous and cyclic electrically heated mats.
All of this electrically heated deicing was infact extened engine deicing so as to ensure that when the ice came off it would be in small enough chunks for the engine to digest without damage. [Another system almost direct from the Bristol Britannia]
The fin nor the rest of the wing had any anti icing system
