hobo twisted the electrons to say:

At http://www.eurofighter.starstreak.net/ there is a picture on the
first page of a Eurofighter from below. Above dorsal intakes is a long
panel with marks on it that appear to be grills. Other airplanes with
dorsal intakes such as the F-16 don't have the long panel and I am
curious as to what it is for.

Isn't the panel just a splitter plate for the air intake? In which case,
the F-16 does have such a feature - it's just implemented by having the
air intake sufficiently vertically seperated from the boundary airflow?
(ie: The F-16, like the Eurofighter needs to avoid getting air from the
boundary layer into its air inlet, however it achieves this in a slightly
different manner.)

I am also curious as to whether what appear to be grills are so, and
if so what is their purpose?

GHowever, I'll confess to being totally stumped as to what those grills
might be ...
