Subject: [JabCamit] Prop size and blade count survey

I run a 66" Whirlwind 2 blade prop that was suggested by Pete when he ran Jab in the states. I had been offered a 3 blade Warp drive prop from a friend who was upgrading his Rotax powered Kitfox.

Pete warned that this would have too much polar inertia.

I would like to know what props those on the forum are using on their Jab 2200s.

Thanks.

Hi Leo,

 

If you have a 48” pitch prop and turn it 3200 rpm, and it is 100% efficient, you would see 126 kts.  I suspect the pitch you have is higher than 48”.

Re: Jabiru 2200 (Ref 22A31_ _) Winding problem

The parts manual, available online from Jabiru has those numbers, and should also have the sizes.  I believe 19 is a standard aircraft bolt and 24 is a standard screw. (I replaced them with some I had on hand)    https://jabiru.net.au/service/manuals/

I think the Camguard shows up as Phosphorous and Calcium (both of those are also present in the Aeroshell oil EP package). I do not think there is Silicon in either the Camguard or the Oil

In review of 25 hours (400 total hours) we have appreciated movement of the winding. After removing the spider, 3 of the 4 fastening screws were broken. We plan to repair it with new titanium screws after removing the rest of the threads.

Any experience with this breakdown?

Flew my re-built 2200 last week. Did a post-flight check inside the valve chambers. All had evidence of oil and equal ‘tide’ marks.
There is no adjustment to the flow, so is my level typical ?

Sounds like you are right on where your numbers are coming from (initial bedding in on the cylinder walls).  Silicon is an element Si in silt or sand (SiO2) so could be also from some dust getting through your filter.

The report looks good with two exceptions that are slightly over average.

Nickle was 8 and unit average is 2. I am trying to remember what the cylinder walls are coated with. I seem to remember Nicoseal which Blackstone says would account for the higher than normal nickle reading. If not that then it could be valve guide wear.

The other high reading is silicon. Mine reads 16 with the unit average at 8. Blackstone says look for intake leaks if none found could be harmless sealer or lube in the form of silicon.

LATER: Just found the info on the cylinders. "The cylinder barrels are electrolytically coated with silicon carbide (ceramic) in a nickle matrix." So this may account for the nickle and silicon readings.

Re: Momentary black smoke

Kerwyn Stoll
 

Hi Peter,
 My 2200 in Skyranger has done that for many years, but only a couple of times a year.. It does it at wide open throttle, when oats are low. My number four cylinder, which is closest to the carburetor, is typically running at an EGT of less than 1100 F (when it happens). I’ve never had anybody mention black smoke. As a remedy, I always Keep my EGTs avove 1100 f (590 C) with my hackman type device. It certainly isn’t a good feeling when it happens, but it is nice to have a way to stop it (mixture control).
I know it could be other things too, but I thought I’d share my experience in case it hrlps. It is awesome having a Heckman device. I wouldn’t want to fly without one.
Best Regards,
Kerdog

Good evening all. I have an X’Air Hawk with a Jabiru 2200A hydraulic lifter engine. I assembled this machine in 2009 and it has performed well for350+ hours. During lockoff, lockout or whatever it’s called -it has been regularly turned over. I did a maintenance flight of over an hour during February which was uneventful. Yesterday, on the second flight of the day, on climb out, she spluttered and vibrated for a few seconds. Observers on the ground noticed a plume of black smoke from the exhaust until I levelled off after the climb. T’s and P’s were normal.  The engine was warm from the previous flight. The choke was not used and was off. I had new fuel and took a Curtis valve sample (clean) prior to flight.
 After a pleasant, smooth I thirty minute flight I put the aircraft back in its hangar at Daedalus (now called Solent airport)- and went home, 75 miles away!
I’m planning to go back soon and whip the carb’ off to check out a possible rich mixture problem. I have been advised to conduct leak down and cylinder compression checks too.
Does anyone else have experience of this fault - or ideas on where to look?
Kind regards, Peter
