Quiet Vent

[Ron (RW)]

Some months ago, I read a post from a John Morgan, Minden NV. He was
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)

[bumper]

The Quiet Vent kit has been re-designed. The new design provides the same 10
db noise reduction* as the original design. However it is more robust and
less "fiddly" to install.

To order, send $5 USD and a stamped, self-addressed envelope to:

John Morgan
194 Taylor Creek Rd.
Minden, NV 89460

Money back guarantee if you are not completely satisfied (simply return QV).
Also, any original design QV that proves defective may be returned for a new
design QV at no charge.

* Noise reduction measured with the pop-out side vent fully open (this is
the vent in the sliding Mecaplex window) and was measured at pilot's head
level while at 60 knots in my ASH26E).

Also available, the MKII "high tech" yaw string. Clear turbulator base,
natural wool yarn - $9 USD.

Anybody got a picture of this device? Any testimonials on how well it
works?

Thanks,
Ed

[bumper]

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.

Okay John, you've piqued my interest. Any chance you could send me the

order one?

Ditto for me, both questions. If you don't use it, PayPal is great for
this kind of thing.

I do apologize that the QV kit is so cheap. However, it's not all that labor
intensive to make once the jigs are set up etc.

On the other hand, the expensive ($9) MKII Yaw String is more labor
intensive to make, with lot's of steps:

Hydraulic punch die cuts clear plastic disks and marks center of disk.

Paper cutter, with jig, slices two sides off each disk to make "pie" slice
turbulator shape.

Template used to punch small center hole. (Note that all the above could be
done in one step if a relatively expensive custom made die were used.)

Natural wool yarn is threaded through hole and flayed out. End of yarn
knotted

Base is put on clear adhesive and excess adhesive trimmed by hand.

Index dot punched out and placed on under side of yaw string base for
storage.

I ought'a raise the price (g).

Sorry, no website - - I'm a computer dummy. You'll just have to email me
privately if you want more info.

all the best,

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,

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.

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,

Hi Bumper - I'm very concerned about the price,
being a glider pilot and therefore cheap by definition.
Do you offer volume discounts so we can equip our Duo ?
Thanks,
Best Regards, Dave

PS: Is the special yaw string also affixed at the rear
to improve my flying ?

Dave,

You're not the first to complain, a number of pilots have taken issue over
the inexpensive price, I mean, "How could it be any good if it's so cheap?"
It's cheap because, even though it is made of high tech materials, it's
small and light weight. In fact, it's so light that if I charged much more,
purchasers might hunt me down and hurt me - - I'm basically a coward.

So to please those Duo owners who'd rather spend more, I've come up with a
special deal just for them - 2 for the price of 3 . . . wowser!!

I'm also working on an "always straight" option for the MKII Yaw String that
is sure to please even the most dead footed back seat Duo pilot. It keeps
the yaw string nicely centered no matter what you do with the rudder.

all the best,

You've emailed me twice asking how to order a Quiet Vent kit. I've tried to
reply each time, but the email "from" address is rejected by my service
provider as "not valid within DNS". The email address also doesn't look
"right" to me, but I'm no expert and have no clue what that DNS message
means.

If you'd like to order a QV, send $5 USD and a SASE to:

Dan, Thanks for rapid response ,I recommend these, I noticed the noise without it, also to Iain Baker in the UK who phoned me even more rapidly extra thanks, wow,Steve,

[bumper[_4_]]

Thank you for your kind appreciation of the Quiet Vent.

A lot of good people in soaring!

Due to a back injury, I removed the MKIV yaw string and Quiet Vent from distribution a few years back to try and reduce demand. Paul Remde, with none to sell back then, graciously left them up on his Cumulus website so his customers could order direct from me.

Still too busy. Fortunately, Sean, of Wings & Wheels, purchased the MKIV and QV business last year. Said he intended to make them available to other soaring distributers once he got things up and running. When he did that, I got a free sample - I told him I could not have made it better myself, excellent quality.

For me, the MKIV, QV, SRS (Smooth Ramp Sliders for Cobra trailer ramp), along with half a dozen other parts for Schleicher gliders, have been more hobby than business, a way to share. I am pleased they'll continue to be available as I back out gracefully, well not always so gracefully I guess.

Thank you all for the years of support (the first MKI yaw string was invented 20 years ago!).

Good soaring!

Paul,

Most were designed for my ASH26E, though some have found broader appeal. Briefly:

"Spools" that screw into the Rogger hook canopy jettison pivot, to hold seat belt tangs conveniently out of the way to prevent them from getting behind the chute when entering glider.

Fuel vent overflow system to prevent fuel all over tail wheel fairing when fueling.

Tail wheel springs that improve steering authority by 50% while reducing preload on hinges by a factor of 5.

The Cobra trailer SRS (smooth ramp slider) to stop the grinding and damage (which you already have).

All I can think of now . . . might have lied about "half a dozen" :c)

Second that!

Looks like classic great German engineering - make it with as many parts and as much complexity as humanly possible while still retaining some chance it may function reliably and long enough to make it through the warranty period. Oh, extra points scored if people stand around in slack jawed wonderment to watch the thing cycle.

I remember one rather elegant electric self launch that had me doing that just watching the pylon extend/retract. :c)
