Posted: Sun Jun 10, 2007 8:01 am Post subject: Air venting

Does anyone know of  air vents that are available to be fitted to the side of the cockpit skin to  direct outside air on the pilot and passenger,  I am looking for the type  that have a flange on the outside to cover a rough cut opening.  Metal or  plastic of good quality is desired. If so, I would like to see some pictures or  be directed where I can see pictures.

      In trying to solve a  problem of high cockpit heat, I installed heat shield materiel on the firewall  and wrapped some tape around the exhaust pipes made by Thermo Tec.   This reduced the amount of heat signifently, however it's still too warm for  summer flying here in Central Texas

Do you mean in addition to the factory NACA  vents?

  

 How about a vent in  the canopy? Spruce p/n CC3251 or 05-01179. Cut the hole by hand with a  fly-cutter in under an hour. Pictures attached of a vent installed on Doug  Dugger's plane.

Hi  Robert/Tracy Stone:

Check out Vans. They have a vent that fits in the wall, and puts a scoop 

out into the slipstream. I got two, installed one, but haven't flown 

with it yet.

They also have adapters for the plastic eyeballs, and cheap air hose.

*Tracy,

You can make your own channel for the inside behind a NACA opening and 

add a louvered adjustable air vent out

of a GM auto for very little.  They work very well so long as you 

position the NACA intake at or forward of the leading

edge of the aircraft.  Air vents over the wing can actually suck air 

from the cabin or minimize the flow due to wing lift.

I built my own and it only takes a little time.  There are commercial 

equivalents, but most get into your panel with a

spherical vent.  The GM vents are cylindrical and have adjustable 

louvers.  About $3.00 for both. See links,

Craig,

      Yes, I have the factory  NACA vents installed but cant get the airflow adjusted any higher than my  chest.  I just called Aircraft Spruce and ordered a pair of the plexiglass  vents which I will install on the canopy sides so I can get cool outside  air blowing right in my face.  Thanks much for the  information.

Thank you for the compliment Bob.

It was a wonderful process, building from Zenith plans

and I really enjoyed it.

Larry

My foggy memory thinks people used WD-40 with the  hand-turned fly cutter to make the opening in the canopy. But this is  second-hand.

  

 Do your NACA vents lead to eyeball vents in the panel? If  so you might try larger 2 inch eyeball vents:

eye ball vents are just not enough in the noon FLorida sun.

But, the NACA vent blowing up your shorts is the best angle of attack indicator money can buy.  I use it to judge climb speed/angle, to set cruise configuration, and to judge final approach.  Why do you want it blowing on your chest?  You are losing a valuable flight instrument!
