How do you pronounce NACA?
I'm doing a presentation on aerodynamics tomorow and part of it will be about NACA ducts.
But is it pronounced like NAKA or NASA? I always thought the C was soft, but aparantly the organisation NACA was renamed NASA. And surely the american
government wouldn't spend thousands of dollars on a name change when the company sound stays the same? 
So, seriously, any thoughts?

From Wikipedia

NACA was pronounced as individual letters, rather than as an acronym.

but they won't work there................or if they do, they won't work as they should.
they're designed to be in laminar flow on a wing for example, to create a pressure differential without disturbing the flow rather than in that
puddle of turbulent air behind the screen.

NACA duct - often pronounced "knacker".' race and rally car sourcebook - allan staniforth

No worries Tom - they are there for water drainage and heat venting from the engine bay at standstill

NACA prounounced Nacka
NACA is not the same as NASA.
NACA was the acronym for National Advisory Committee for Aeronautics a fairly small research establishment based at Langley which was founded in WW1.
NACA did a lot of fundemental research in the efficiency of aerofoil sections and sections for jet engine compresor and turbine blades.
In 1958 following the Sputnik mass hysteria in the US it was absorbed into to NASA.
