Quiet Vent

Bumper-
Is this a vent quieter for the side window ?--
Posts suggest that to be the case. If so, I will mail you an order for one.

Ed,

The Quiet Vent kit is relatively new and has not been marketed
commercially. It's only been mentioned on this newsgroup and on the Stemme
and ASH26E groups. I've also sold a few of the first version of QV at
Minden where I'm based. That said, there are enough of the first QV
version in use that you may get a testimonial in response - - maybe.
Please note that the first version was not robust in use and could fail at
sub-zero temperatures. The seal, if not installed exactly right, could
vibrate like the reed in an obo! I'm replacing these at no charge.

The QV is completely clear when installed, so good pictures may be
difficult. If you email me privately, I'll send you a picture that has the
QV colored with a felt tip marker so it shows up well - - I did this for
the instruction sheet.

'Course you could always take a chance and order one, only $5 - -
cheerfully refunded if you're not satisfied.

Hartley,

Yes, that's what it's for.

The standard Mecaplex sliding window usually has a small rectangular
flip-out window. When open, this window sticks out into the air stream, but
it's noisy.

Much of the noise is caused my air turbulence, as some of the incoming air
strikes the back of the vent opening, the small mounting block for the vent
hinge, and finally the handle for the vent.

The QV kit eliminates most of these obstructions by attaching to the inside
face of the vent handle, then continuing forward to seal against the inside
surface of the vent, thus providing a smooth and rounded surface for the air
flow.

It's a simple device and certainly possible for others to copy and make
their own. That's part of the reason I've priced it so low - - so they'll
think, "Why bother, I'll just order one". Besides, I've done lots of testing
and worked out the bugs. Just ask any of the people who purchased the first
version only to have it vibrate like an oboe reed or come off during
super-cold wave flight!

Just for info, I know there is or was a company that manufactures a complete
replacement for the flip-out vent that is supposed to address the noise
issue. I've not tried their product. I googled, but could not locate
them - - as I recall, they are located in CA. So at least the idea of making
this vent quieter is not new.

all the best,

developing a gadget that was to diminish noise from the clearvision
panel vent. I think he called it the Quiet Vent. Any further word on
his venture? Any contact info? THNX Ron W (RW)

To add a bit to the other posts here, John is an inveterate tinkerer
and was rumored to be close to winning the prize for the Stemme factory
adopting 100 of his suggestions when he sold his Stemme for an ASH26E.
More seriously, I can vouch that John is in this for the fun of helping
others. At $5 or $9 each there's no way money is the motivation.

That said, it might help to describe the QV. It's a piece of flexible
plastic with adhesive on one end that makes a smooth curve on the vent
window, eliminating the turbulence of the sharp edges of the existing
vent. That should reduce noise and John made measurements on his ASH
that showed 10 dB reduction. On my Stemme, I'm not sure it's making
that much difference and I was supposed to do a test for John a few
days ago when I was up at Minden, but we got busy with other things and
the test will have to wait til next trip. John's concerned that the
lack of a good exhaust in the Stemme cockpit (it's pretty air tight)
may cause the QV not to work as well, hence the test.

BTW, all this thread is about QV's and the MK-2 yaw string is being
overlooked. I've had one of those for a while and love it. It replaces
the ugly tape with a small clear plastic diamond (again with adhesive)
and makes a beautiful ship just a little bit prettier.

As you can tell from the above, I'm a good friend of John's so you can
discount my comments as much or as little as you want. But if you talk
to the Stemme and ASH26E owners who have benefited from his many
innovations, you'll be grateful he became a soaring pilot.

Just received my QV today. Very quick shipment I'll be installing
it this weekend. Thanks, John RW

hi
is this device removeable? we can't have permanently
fixed stuff on our planes here in europe without a
lot of hassle.

thx

Yes, the QV (quiet vent) and also the MKII "high tech" Yaw String are both
removable. They are attached by first cleaning the canopy or vent plastic
with denatured alcohol, then are installed using a clear acrylic adhesive
that is pre-installed on the QV or MKII.

This adhesive has been weather tested for over two years of constant
exposure in the California sun . . . I wanted to be sure that there was
absolutely no chance of damaging expensive canopies. Removal is simple, pull
off the plastic QV, or MKII top layer, then use finger or thumb to "roll
off" the adhesive. It coves off clean, leaving no residue.

So, if your aviation authority would allow you to put a yaw string on your
canopy without a hassle, or affix a pen holder or other device temporarily
with double sided tape or Velcro, they should have no problems with either
of these.

all the best,
