Intake naca duct

[Pierre-F]

friends,

do you know if NACA duct in 1/20 or 1/24 exist ?

thanks all

[Tyrone]

I guess you'd need to know which model / car. As there isn't a standard size NACA duct?

[Pierre-F]

well, if I look closely a B188 or a F189 or a MP4/5B , all NACA intake look the same, maybe I'm wrong

[Pierre-F]

MP4/5B , on the real F1

Did you measure the dimensions? I almost don't believe that they are all exactly identical, as Tyronne has already written.
And I don't think there is anything there either.
I made some myself for an M7B.
But I haven't seen it as a "standard element" yet.
But of course a lot is possible.

Well, I would think about a PE sheet with many sizes, I saw a 1/43th scale sheet sometime

You did very very nice parts !

I only know this PE...

but there are just the grilles and the frames.

NACA ducts come in all sorts of shapes and sizes (long, short, wide and deep) dependent on the amount of air needed, thus a small NACA duct in 1/24 scale could work just as well as a larger duct in 1/43 scale. Click on this link:

For an explanation.
To see NACA ducts of different sizes that I have made in 1/12 scale on the nose of the 312B2 Ferrari and on the engine cover of the McLaren M16 click on this link:

Alternatively put “NACA duct design” into the search engine of your choice click and be prepared to be overwhelmed with information.
