--> Yak-List message posted by: "Jay McIntyre" <jayatnowra@hotmail.com>
Does anyone out there have any spare Nose Oleo seals (P/N H2-4210-17). Doug has
been able to provide 1, but I require another 2. Please contact meoff listif
you can help. Thanks...
I might be mistaken, but the first 'drop-tank' style auxilary fuel tanks were made
by Greg Ryan and the boys at Aerotech in Auckland, New Zealand back in 1997.
They were fitted to ZK-OIIand were seen at 'Warbirds Over Wanaka 1998"- See
the photgraph in 'Classic Wings Downunder' Magazine(Vol 5, No 3). (BTW, this
issue has a brilliant feature article on the CJ (featuring our machine ZK-WOK).
Contact me at the above address if you are interested in a back issue!)
I have not seen them fitted for a long time, (whether or not they had problems
or not I do not know), but of course we don't have great distances to cover down
here in NZ! They do look fantastic and, if I remember correctly, did not have
a great effect on cruise speed.
Regards, Jay

| Subject: | Nomex or .. Kermel |
--> Yak-List message posted by: "Stuart Mackereth" <stuart@bramptonyork.com>
Hi
Does anyone know about a material called Kermel? I've been told it is as
effective, or better, than Nomex - but lighter and crease free - i.e.
better for warmer climates. Apparantly it comes from France.
A local flightsuit manufacturer has tossed Nomex in favour of Kermel -
and I was wondering if anyone had experience with this new stuff, before
committing to an unknown fabric.
Thanks

Stu,
Just found this:
Kermel fibre does not melt, nor form molten droplets, and therefore will
not stick to the skin. Instead, it will slowly carbonise. If Kermel fabric
remains in a flame, it will blacken and become slightly more rigid, without
shrinking or forming droplets. The textile structure loses its mechanical
properties but maintains its structure, which is an essential point for use
in protective clothing. These characteristics allow Kermel to ensure a high
level of protection, even after exposure to an intense heat flux.
Kermel fibre maintains its mechanical characteristics well beyond the
melting point of most synthetic fibres. It is necessary to reach a very high
temperature to notice a complete degradation of the fibre. At 400C, only a
5% loss of weight can be registered with a thermogravimetric analysis at 5C
per minute.

Shucks Walt, I admit publically that I owe you a beer, maybe even two. But never
having flown the Yak-18A, I certainly couldn't comment on the docility its
stall characteristic (or lack thereof).
But I love loading up the CJ in a steep bank and then holding it in there at the
edge of an accelerated stall.

The idea of fuel behind the rear seat is interesting. The structure is clearly
designed to carry the load of the avionics and their power supplies. That is
a couple hundred pounds. Replacing that weight with fuel makes a lot of sense.
If you design the shape of the tank properly the problem of unporting during
large pitch excursions could be minimized. Generally it is better to extend
the tanks laterally rather than longitudinally since we don't really fly the
airplane in uncoordinated flight that often.
The only down side is that the CG will move substantially foward as you burn off
fuel.

Here's a source for Kermel flightsuits. Priced about the same
as new Nomex (not e-bay).
http://www.airwear.co.za/productpage_fireresistant.php
Here's some interesting comments from their web site:
"As a minimum protection with a closed cockpit, avgas or jet fuel driven
aircraft/helicopter, we recommend to wear a suit made in 100% cotton. The
best protection is a fire resistant Kermel or Nomex suit. With the correct
fabric weight, a suit of this type will give excellent protection in the
event of a flash fire or to a person having to run through a fire.
"Over the years, we at Airwear, have found that a 230gr/m (~7 oz) is the
most effective fabric thickness to use. It offers very good fire protection,
retains a reasonable amount of body heat in winter and is very acceptable in
summer.
"Incidently cotton socks or at least a high cotton content pair of socks and
leather shoes, preferably boot types, are of utmost importance. Sneakers are
a definite no-no."
Have fun,
Roy

No resistance to wearing one. I usually wear one. I am exhibiting
resistance to be told I *must* wear one.

I will say that when burning fuel out of my CJ's aft-mounted aux tank I
have to adjust trim "back" as the fuel is used (every 10 minutes or so).
Your point on weight is well taken. When the fellows installed the aft
tank they weighed the bulky radio gear that came out of that area and
determined the fuel weight that would replace it at the same w&b station.
I forgot to mention previously that I never take off on the auxiliary
tank due to the same porting issues related by Jim Griffin. I have
never experienced it but the previous owner told me it would be a good
idea to operate this way. Also my bird has an electric fuel pump
instead of a wobble pump along with a new front-rear selector for the
fuel system in place of the original valve (here we go being test pilots
again). I also have the Cessna vents in one wing tank that has had the
seeming effect of equalizing fuel burn between tanks. I threw that last
one in just to poke at the ant hill with a stick (I have memories of
long-ago discussions on this list about fuel venting).
Variety is the spice of life. Or death.

I had one more insight into the aft-mounted internal aux fuel tank vs.
the external centerline tank. I'll take a gear up any day with the
internal tank vs. the external tank(s).

If a internal tank is installed behind the rear seat is there any room for
baggage ? I all ready have a smoke tank back there. Getting 1 hr extra fuel
would be great for crosscountys.
any one have any experence with the center mounted external tank or any
pictures.
