REFLECTOR: Performance Exhaust

[Scott Derrick]

I've been told NACA's don't don't do much of anything in regards to 
sucking when installed backwards.

they make a cool looking exit duct but thats all.

> Just a thought, since we use NACA'S for our cooling plenum what about a NACA for the exhaust? I would think a NACA with a 1 to 1 width to depth ratio of ramp for the exhaust would act as an augmenter running parallel to the free stream flow to get the exhaust up to the slipstream speed.
