Cabin ventilation.

[Aerosport1]

The Aerosport NACA valve controller could be made to open one valve and close the other. Also Our new AEROVENTS seal off the air about 99% or more when closed.

Just an FWIW
I have 2 NACA scoops feeding my overhead and while on the ground with the engine running and valve wide open I do get airflow thru the console and it is better than no air. The air you get is enough for some relief. On hot days I have the valve wide open on the ground and once I get to about 1000 ft AGL I close it down to about have and then adjust eyeball vents to each passengers comfort. I flew my airplane for about 3 months in the winter here in Ohio before installing the valve. I had the valve completed and ready to install before the first flight but I thought maybe I will not need this. Well after flying it for 3 months in the winter I decided to install it. The big difference is in the winter you do not want that cold air inside the overhead console. It really does make the cabin Colder. Being able to shut the system down is very nice. Another advantage is that a couple times (before valve) I had passengers in the rear and they had the vents open and then the next time I flew it was colder out and the cold air was coming in thru the rear vents and it was not easy to try and close them while in the front. With the valve you can close the system down. I find the NACA controller a very necessary item when you have an Overhead console especially if you live somewhere were the temperature does not get above 60 in the winter. I do feel that 2 NACA scoops are better than just one. But that is from my personal experience.

These are just my thoughts and experiences from flying my RV-10 for 7 1/2 years. If I built another RV-10 I would repeat what I have now for the overhead and valve.

I am not claustrophobic but I hate to be in a small hot space without air flowing freely over my face. I anticipate problems in southern latitudes when I eventually get there, especially as my tip-up will be a little more difficult than the slider models to just crack open.

So, I was wondering about putting an electrical fan in-line with the panel vents. There is a kit by Lonestar but at $389, I think I would just put up with the problem. I have 2" pc fans in stock but I doubt if they have enough oomph.

Has anybody experimented with a roll-your-own electrical forced ventilation system? Please tell us how you did it and how it worked out.

I was thinking of doing the same thing. I am a ways out from needing to solve the actual logistics of this though. I live in NC and an extended taxi without AC can get miserable in the summer.

Joe, I've only got one standard Vans Naca vent located just behind and to the top of the baggage door feeding my homegrown overhead console with four Vans Black Plastic vents. No problem with getting enough air even with all vents open. Others have said they've put only one Naca on the starboard side and it's worked well however I can only speak for mine which has been very successful. So successful in fact that while at Oshkosh I picked up a Control Valve from TCW technologies and will mate that to a Shut off Valve from ASpruce (08-07305) to be able to shut off all air to the console when at sub zero etc. cheers from Western Australia
