Question:
I need information about NACA scoops.



Replies:
I believe that a NACA scoop is used to accelerate air into the intake of a race car. I saw one once on a car that won a motor cycle engine class speed competition at Bonneville. Basically the scoop is shaped to provide a lower pressure leading to the intake manifold. It is shaped like an inverted airfoil in the side of the car. The drop in static pressure results from an acceleration in the flow so you get a supercharger effect (I suppose at the expense of a slight increase in form drag). The design was developed by NACA, the predecessor of NASA, so you could probably dig up a NACA report in a well stocked engineering library.
