| Subject: | New/Prototype Grumman front air vent airbox |
Hi,
Update for people who do not use the Grumman Gang email server.
At the Oshkosh AYA forum, John Sjaardema showed his front vent insert that
replaces the old louvers with a pair of eyeball vents for each side ($80 for
the set).
He also displayed a prototype for a new air vent airbox and is looking for
feedback on the design and interest in members for possible production.
More information and pictures on my blog at:

Cheers!

I see two potential problems with these vents from looking at the photos, w
hich granted is not a very good way to make a judgment.
They are made of plastic which is not nearly as durable as the aluminum ven
ts and typically cost much less.
They are relatively small diameter compared to the original vents and most
likely the air velocity will be quite high which is not usually desirable.
Generally you want lots of air flow and low velocity and the original vent
s did a pretty good job in this regard.
Van's Aircraft sells a much larger diameter swivel ball vent that is made f
rom hard anodized aluminum. It has a round inlet and would have to have s
ome adapter duct to connect it with the Grumman NACA inlet, so it would not
be an easy installation. Maybe the new ducts will turn out to be a good a
lternative to the original. I'd like to hear from someone who has installe
d them. Sure would be nice if they were black instead of white.

Cliff, I bought a set of them at the convention. Mine are black. Work and
other commitments have prevented me from installing them yet. I saw Levy had
posted to the Nazi list that he has a set installed and he is pleased with
his. John advised if I am not pleased with them just send them back and he
would be happy to give me a full refund. I'll post once I have mine in. I
hope to get them in next week one day as I want to get them in while it's
still hot...

No-one has reported the 100F outside temperature test yet....:^)
One option is to completely remove the internal on/off control inside
the eyeball and just use the "vent" push/pull knob for flow control.
This should get you much more air flow, but does sort of negate
returning it....
The part is a hard plastic material (ABS?) that is formed in a 3D
forming machine (also called rapid prototyping) - no molds involved.

One clarification on the airbox version. John said this was a prototype, so
the material, color, and finish don't reflect the final product yet. I
understand the final version would be black and some sort of hard
plastic. The forward end is sized to fit the rectangular opening in the
fuselage (same dimension opening as the existing airbox) and will have a
screen built into the airbox.

Ah a cool 85 here in Wilmington but it feels like 90... I bet your 100 feels

I am surprised that Levy would put a part on his plane that does not
have the proper paperwork. As in no PMA or other FAA
requirements....interesting
Any one concerned about the lack of paperwork and the legality of
installing these parts?

Hi, I saw the vents.? My only thought was they are the plastic eyeball vents and
I wonder how long they will last.? Not a bad idea.? I wish they were more .
. . .? professional? looking.
