I have been thinking of making these for a while and by reading the discussion forums there seem to be a couple of options outlined here
There seem to be 4 options
a)A rotary vane connected to a Hall effect sensor/low friction pot
b)A diode laser(not a clue about this)
c)A 5 hole probe(Seems interesting and doable)
d)Mark Drela's idea of having pressure taps on the top and bottom of the wing to figure out AOA
Has anyone tried these options? I am starting a new topic because the above link is about a year old.
a)How would a rotary vanes position be affected by aircraft attitude or rotation. I would think that these effects need to be removed before measuring AOA/ sideslip
b)Seems most elegant,
c)How would this be calibrated?
d)If i don't know the exact airfoil shape, this is a bit complicated.
Have any of the RC folks had success with these methods?
