Subject: | Next steps - TORSION HARMONICS HISTORY .... |
Hi! All industrious engineers ...!
I would suggest you make an approach to Pat Tunney. He took the BMW Project
under his wing no doubt spent mega bucks in cash and time but I think he
abandoned it as a nightmare. He subscribes to this forum.
For what I know you have a hitherto unsolvable problem since the power
stroke resonance develops a harmonic torsion resonance shock wave to run up
the propeller blades and viewed from a position at the end of the rotating
propeller arc you can see the propeller blade take a shape rather like a
letter "S". (very dangerous place to stand) Europa had an engine c/w
propeller mounted on a car trailer and ran the assembly at a "workshop"
event at Elvington Airfield with minions of customers and potential
customers littered all around waiting for the possibility of certain death!
To my knowledge such a hormonics pulse eliminator needs yet to be invented.
...
..........Perhaps try a "vee" belt final drive to the prop ? .or even
contra-rotating props !!!!!!!!
The Rotax slipper clutch employs a rotary spring loaded cam drive which is
a copy of crank shaft drive situated prior to the primary drive chain on my
single cylinder 1936 Velocette 350 KSS (overhead cam) which maybe goes part
way to effect a solution. Those chaps had wonderful opportunities to
exercise their engineering abilities for the year.
Incidentally ( not to expand on my previous Jabiru experiences) I had a
serious torsion resonance peak induced in the propeller/crankshaft
combination of my Constant Speed MT Propeller which was acceptable since it
could be accelerated though but MT Propeller Engineers placed some
restriction on the operation of the combination. Even, though being a six
cylinder, the torsion graph plotted was scary and clearly defined. With
random propeller mounting extensions the torsion effect can be caused to
develop back along the crankshaft to be between the main bearing journals
and so fail the crank shaft. ( I've seen photographs)

Bob Harrison. G-PTAG

Subject: RE: Europa-List: Next steps -

My understanding is that the Europa work on the R1100 was stopped as they
could not eliminate a torsion vibration problem with the setup. I speculate
that an R1200 installation would have the same problems.
In May 1997 it was being worked on. This was the period when a man called
Adam Kingdom became CEO. Things do not appear to have gone well and he left
in mid/late 1998. News letters in this period are very sketchy.
Other almost certainly know more than I do

Subject: RE: Flyin at Thorney Island.
Hello,
The weather for the weekend is looking great! We look forward to seeing
you at what promises to be one of our busiest fly-ins ever!
Please see updated information attached.
The circuit will be busy please keep your ears open, and eyes peeled
there is no radio and so it is blind calls do communicate with others if
you are unsure! We have found in the past that pilots without a
controller make a good (if not better) job of slotting in together ;-)
You will need to assume that all other pilots don't reach your standard
of airmanship, and so please make allowance for those with skills less
advanced than yours (this is a rule for all pilots ;-) keep a sharp eye
on those who have a different left and right designation than you and if
in doubt give way, we will enjoy watching you flying by a few times
before we brew your tea.
Please feel welcome to fly a low pass on the way in to inspect the
runways if that is your elect, it will be nice to see too! and if in any
doubt Goodwood is minutes away, Sandown and Bembridge less than 15
minutes across the water, make sure you plan these as alternates.
My phone will be on but will be busy so please keep the calls short and
to the point, plenty of time for a chat when you're on the deck ;-)
There are local Army family's who will be interested in your aircraft so
please do take time to show them over your aircraft if your inclined and
if you would like to pop a circuit with them IF you feel comfortable
they will be very grateful I am sure, it is at your elect to offer a
circuit and you should not feel any pressure to do so, we are just glad
to see you.
Thank you for supporting us and SAFFA at this event.
Regards
Daryl
PS: It's not too late to invite your flying friends ;-)

I have only just seen your advert for this weekends flyin at Thorney
Island. Having lived in the area for over 20 years I have always wanted
to flyin so I hope there is still room for me. Can you let me know of
your requirements and availability please.
Thank you.

Subject: | Re: Top fuselage- rear flange gap problem |
Thanks for all the input. Troy, you are right about the top of the firewall bending
forward- mine does that as well. I did however push it back when taking the
photo above. I will certainly try you method to get it straight.
Bottom line is that the gap seems here to stay. It can't really be any other way-
pulling the top further back would only make the tail and FW flange misalign.
Strange that a systematic non conformance like that is not either corrected
(trimming less at the factory) or mentioned in the manual.

Just on the subject of belt drives, one of the australian builders of
scale spitfires and mustangs now too i believe. they use a tooth belt drive
on 350hp V8 engines to stop any harmonic issues arrising between engine and
prop this may be a good soulution to the issue, but will require a bit more
engineering than direct drive, or gearbox i suggest.

I am surprised and disappointed by the number of replies I received to
my query about LEDs packing up. Thankful for the number of replies but
disappointed that so many people have had or are having problems with
this part. At $100 a pop this does not seem right. Has anyone contacted
Ray Allen to ask why?
Thanks especially to Greg for the detail and potential repair strategy.
We will have a look at that more in the UK.

Hi Steve,
I didn't reply to your earlier email, but thought I would this time. We
also had the display go bad and replaced it. It has been OK since. One
thing we notice is that the display is very sensitive to the radio, when
we transmit, the LEDs flicker. It might be that the long wiring run
back to the tail is picking up enough RF to burn the things out. Maybe
the wiring needs shielding. Just a thought.
Regards,
Terry

All,
I'm jumping into the middle of this since I'm located only a few miles from
the Ray Allen Company. I just talked with Scott (one of the owners) and
relayed your problem to him.
His response was that, yes the early "MAC" label had some problems because
they were over-driving the LED's. Some models that were shipped sometime
between ~2004 & 2006 also had some connection problems because of the Lead
free solder they were forced to use for European shipments. The later Model
RP-3 had no problems that they are aware of. The good news is that if
anyone is having a problem, just let Scott know (<Scott@RayAllen.com> and he
will replace it at 1/2 price. ($43.00 US plus ~10.00 Air Parcel Post) No
need to return the failed part.
Hope this helps

Thanks Dale - it is good to see the power of the forum and thanks for
taking the initiative. I will contact Scott.
My lights probably were issued by Europa in 1998 but I have only flown
for the last 4 years (220 hours and smiling).
