Interesting stuff. I've just one question: what was
the Standard probe,
IOW was it a non-swiveling Smolik probe or something
else?

Thanks for the interest. I asked Dr Smolik your good
question and here is his reply:

Hi Paul ,

quick answer, yes the reference probe was an identical
one, more then that, it was indeed the same one,
that means 3 way and yaw free.
By the first measurement I used it as a swiveling probe
and measured the velocity and the TE-low pressure as
a function of yaw angle.
Then I taped the small air foils to the CFK main tube
and made the same measurements with such fixed probe.

In case you have not yet watched the short youtube
video of the 3-way probe in question...

Hope this helps. Dr Smolik is going to start posting
soon to this group, and will be able to answer questions
quicker and better than I.
