Hi guys,
I've got an RV-10 underway in my garage right now, and one of the things I'd like to do is give it a real air-conditioning system. My specific challenge at the moment is coming up with a good way to ingest and then expel the air for the condenser. The airflow is about 500 cfm and is driven by a high-dP axial fan. I need to be able to get full flow while standing still on the ground (hence the fan), but also add minimum disturbance to the external flow while in the air.
My current thinking is a NACA inlet mounted on one side of the aft fuselage that exhausts to a wedge/ramp outlet on the other side of the aft fuselage. This makes the internal ducting a fairly straight shot, which is good for minimizing pressure drop and maximizing simplicity.
Is this a reasonable idea? Should I be concerned that sucking on one side of the fuselage and blowing on the other will create a problem?
The exit in particular is an area that I've had trouble finding good design resources for. The system may be turned off for a substantial portion of the flight and it would be desirable to not add lots of drag when the system is not in use.
Thanks for any advice or references,
David
