hey guys john from fly Mykel comets they
were looking at the inner workings of a
turn coordinator so you can see we have
an electric motor inside there spinning
that brass gimbal or that brass weight
around and that is giving us a
gyroscopic force and you can see that
although when we tilt this left and
right we get a little bit of indication
as toward our bank it's really more
about when the whole aircraft changes
its heading showing us the rate of turn
so if I turn this very slowly to the
right I see a small rate of turn but I'm
faster the right see a greater rate it's
just the tendency of that gyro inside
there to resist the turning motion and
in turn turn in towards a tilting motion
that we read on our instruments so it's
an electrically driven instrument we're
relying on electricity to spin our
electric motor there and as I like the
quarter spins it spins that brass weight
which gives us rigidity in space and
that rigidity in space is what gives
this instrument its ability to tell us
our bank or rate of turn information of
course we have the little red flag
showing there because we haven't
unplugged from the electrical source
when we plug it back in the little flag
would go away so it is totally possible
to have that little flag gone have
electricity provided to this instrument
and not have the instrument working at
all because although electricity may be
provided to make that little flag go
away the motor itself could burn up or
basically the brushes could get old and
that's exactly what happened to this one
that's why it's being pulled out of the
aircraft and replaced with a brand new
model and this one just has run for a
thousands of hours from 1991 till now
and had plenty of black dirt from the
worn-out brushes when we pull it out so
basically you can see just your normal
electric motor in there with your
brushes and then your weight on this
side and just that tendency of the
weight to spin around and very fast
creates a gyroscopic force that gives
you your bank information and of course
our ball works regardless that's simply
just a slip skin indicator that as
there's some difficult force or in this
case just normal gravity pulling the
ball one way or another it's going to
indicate so the ball does not need
electric
or vacuum to run and this little
instrument is just as it says on top
there DC electric no pitch information
just bank information hey guys thanks so
