    ... the German wikipedia entry as well as some other internet pages (many of them clones from the wikipedia entry though) mention that the flat&wide radiator intakes of the Bf 109 provided some degree of boundary layer control due to their suction effect.

    I know that research in that area was done in Germany since the 1920s and that later (jet-powered) Messerschmidt concepts were to use this principle, but was it really a reason for the shape and placement of the Bf 109 Fs coolers?

    Far as I know, the design utilised boundary layer airflow to allow the radiator baths to be more streamlined, and of lower profile, than those used on the earlier Bf109E.
    There was a thread and diagrams of this somewhere here on the forum some time ago, IIRC.

    Ah, I think you're right Bill.
