Re: REFLECTOR: NACA scoop
Aircraft engines are inherently designed for downdraft cooling. Think of the
Cessana, Beech, etc. Ram air comes in the nose by the prop, down through
engine, then out through cowl vents. Most aircraft engines have the exhaust
on the lower side for this reason. With upflow cooling, the hottest part of
the engine may get cooled first, but then that heated air reaches the cooling
fins on the mid to upper parts of the cylinders. The problem? you dont need
to worry so much about cooling the exhaust stacks. The cylinders are what
need to be kept cool.
