KR> Antenna Questions/Carbon Fibre/Graphite

[Edward Spyker]

Regarding applying copper tape antenna to a carbon fiber shaft or backing.
This string made me curious and I spent about an hour trying to educate myself. 
http://www.antenna-theory.com/
I learned that I am not that curious, but if anone else is, this appears to be 
a very good resource.
Respectfully,

This is the reply I have been waiting for! Please give me a quote to
manufature, as close to the fire wall as possible. I'll move the battery
inside. The cg is foreward now with the 70 litre tank. Thanks Dene

KR> Swift Fuel

[Dann Johnson]

 
 
The Swift Fuel Web FAQ page ( apparently written about 18 months ago ), stated 
that their goal was  to have Swift Fuel for sale at airplane gas pumps in 
Spring 2010.  Maybe they will be able to make it in time for Oshkosh

I am doing a war replica using my KR plans and need drawings, plans etc to 
make the landing gear as WAR and/or Loehl do. Does anyone have any plans, 
sketches and  ideas on this?

KR> Antenna Questions/Carbon Fibre/Graphite

[Dana Overall]

I know there are a lot of roll your own people on the KRNet and all the best to 
all you:-), however I used a simple store bought whip antenna and it worked 
great.  For my VOR I used a wingtip mounted Bob Archer antenna, see: 
http://www.aircraftspruce.com/catalog/avpages/archer_antennas.php  It worked 
great as I rode many an ILS down using this antenna.  Look at Model 6 on the 
above page if you want a plug and play version for the com in a KR.

KR> Swift Fuel

[erickelshei...@att.net]

    This was taken from the FAQ on the Swift website. For
anyone who is interested in this. They also have a video or two you can
watch. I hope it makes it myself only time will tell.    Eric Von Kelsheimer  




FAQ


  Q: Is there any ethanol in the SwiftFuel?

A: No! The SwiftFuel contains no ethanol.  We 
can use the output stream of a modified ethanol plant to produce SwiftFuel; 
however, there is no ethanol itself in our fuel.



  Q: Is SwiftFuel petroleum-based?

A: No, one major goal of the SwiftFuel project 
was to develop a 100% renewable substitute for petroleum-based fuel.



  Q: Does SwiftFuel come from bio-renewable products?

A: Yes, all components of SwiftFuel can, and 
will, be derived from renewable, natural materials.



  Q: Does SwiftFuel meet the specifications for ASTM D910, grade 100LL?

A: Yes, SwiftFuel
meets the specifications for ASTM D910, grade 100LL, and will soon be
in the process of independent verification and approval by the FAA.



  Q:  Is there any alcohol in the SwiftFuel?

A: No, there are no alcohols of any kind in our 
fuel.



  Q: When can I buy the SwiftFuel to use in my airplane?

A: Our goal is to have our fuel at the pump for pilots to buy in 18
months.  Our deadline is Spring 2010, when 100LL is hinted to be banned
for use in the US.



  Q: What is the MON (motor octane number) of SwiftFuel?

A: The MON of SwiftFuel is 104.1, as compared 
to 100LL, whose minimum is 99.5.



  Q: How much testing has been done on the SwiftFuel?

A: We have done lab testing and static engine testing ourselves, and
have also sent several samples for independent verification through
ASTM laboratories.



  Q: Is there a problem with gumming in SwiftFuel?

A: No.  The potential gum number, as provided by independent
laboratories, is between 0.6 ? 1.8 mg/100mL, which is substantially
lower than the specification of < 6.0 mg/100mL per ASTM D910.



  Q: How does SwiftFuel compare to 100LL with regards to emissions?

A: SwiftFuel actually produces less harmful emissions - NOx, 
CO, and SO2.


   Q: What planes will be able to run on SwiftFuel, and what modifications will 
need to be made beforehand?


A: Any aircraft that is certified to run on 100LL will be able to run 
on 
SwiftFuel
without any STC?s (Supplemental Type Certificates) or modifications of
any kind.  A pilot can taxi their plane to the pump as is and fill up
with SwiftFuel once distribution begins.
Q: Is SwiftFuel produced using the Fischer-Tropsch Method?

A: No, the Fischer-Tropsch Method is not used in our production
process, as we have come up with a practical production process in
order to keep manufacturing costs down.
Q: What is the projected cost of SwiftFuel?

A: The ideal price for SwiftFuel
should be less than half of the cost of current 100LL AvGas; most
importantly, the price will remain stable due to its origin.
Q: Is SwiftFuel compatible with all existing engine parts with which it 
will come into contact?

A: SwiftFuel
is expected to be 100% compatible with all existing engine parts,
gaskets, seals, etc.  To this date we have not seen a problem, but we,
and the FAA, are evaluating all elastomeric seals that are known to be
used in GA.
Q: Is SwiftFuel hydrophilic (does it hold water)?

A: Unlike ethanol, SwiftFuel
does not hold water, which means that the fuel will not freeze at
altitude.  Also, this means the use of biocides, as is done in Jet A,
is not necessary because the lack of water prevents microorganisms from
growing in the fuel.

KR> Antenna Questions/Carbon Fibre/Graphite

[Larry Flesner]

I'm certainly no antenna expert but I would have a concern about 
building an antenna in to any part of the aircraft structure.  You 
are betting that you will never have an antenna or connection problem 
for the life of the aircraft.  Fortunately, I was made a gift of the 
antenna I'm using

(http://www.advancedaircraft.com/  and it works GREAT.  I'm guessing 
a builder could build one of similar design and get similar 
results.  My antenna is tie-wrapped to the second cross member behind 
my baggage bay.  It's length is greater than the vertical height 
available so the top and bottom elements are simply bent in a forward 
direction when they contact the floor and turtle deck.  It passes 
within 6 inches of my elevator cables.  Using this antenna and a 
cheap hand held radio, I often hear radio chatter 75 miles out, have 
talked to approach control and tower 35 miles out, and always get a 
"loud and clear" response.  I've communicated with Langford at 50+ 
miles on several occasions.  If I ever have an antenna problem I 
simply remove the access panel to my turtle deck area, clip two tie 
wraps,  and I have my antenna in hand.  Keep it simple and keep on 
building.  Flying is MUCH MORE FUN. :-)

Well I think the current will be carried on the outside of the tube or
copper spiral (faraday effect) just as I seem to remember reading vaguely it
is in solid wire???.if so then the conductivity of the internal
structure would seem largely  irrelevant unless groundedhmmm
