John B.
The carburettor heat scoop directs external ram air into the carburettor and there
is a good reason why this heat is sourced from cylinder heads and not the
exhaust system.
Simply exhaust heat would be too fierce and would risk detonation of the (now heated)
fuel/air mixture in the supercharger where compression adds yet more heat.
Hence the cockpit inlet temperature gauge (sensor in the scoop intake) has a 10-45C
safe operating range and it's hazardous for the inlet temperature to become
>60C for the detonation reason given above.
This leads to an important pre-flight check to make sure the lower engine cowl
retaining teather hook is in place, if it falls out it can work its way back in-flight
into the inlet air heat scoop opening and (on operation) can jam it in
the closed position ... on a summer's day that can easily take you past 60C.
Also note that it can fall out in-flight with aeros and, on my aircraft (yours
may be different), seems more likely to do so if the hook is installed from the
front facing the rear. Hence I make sure during pre-flight checks that the hook
is installed from the rear i.e. facing forward.
Hope this helps.

Of course, you're talking about the Yak 52, and the 18 T has a similar
system. But Sukhois do have ram cold air to the carburettor, but then this
is allowed to mix with hot air from the cylinders, and there is absolutely
no alternative air available!

| Subject: | Nanchang Magnetic Heading Sensor GHC-2 |
I am looking for information for the compass on my CJ. Why does it have a clear
window by the vertical stabilizer? The paint shop did not cover my compass
window and I am curious what effect that would have.

Try Doug Sapp, George Coy or Jill at M14P.com.
To the best of my knowledge the same size nut is used on all other engines
in this series ( AI14, Huosai and M462). In all probability the strength
specification is the same but to be certain you could take a sample of each
to a test facility for a Rockwell "C" comparison.

Hi Phil;
None!
On the CJ the heading sensor is actually a "master" magnetic compass. It is
calibrated (swung) in the same manner as any other magnetic compass but
whether the window is painted or not you probably could not see through it
in any case. If you want to swing it you would remove the access panel.
I made the cardinal sin some time back by assuming on this list that the Yak
52, etc. had the same antiquated system. Big mistake, they are much more
modern.

Hello Walt,
Thanks for responding. I am curious why the sensor has a window. As of tonight,
my sensor has a clear view thru new plexi.

Take a look at the Web site for ARP racing parts Bolts Nuts metric and SAE.
They make flanged reduced diameter twelve point nuts very high strength
materials
which would make getting a wrench on them much easier.
