 |
|
I have a Dynon D10A. Would be nice to use the AOA feature. Already have a
pitot/static under wing of my Europa.
I am thinking a probe high up on the rudder may work and not complicate
rigging the wings or hurting anything when wings go on trailer.
Dynon sells a boom mount AOA/pitot, part number is 100532-000 but it is 1"
in diameter and has a pitot.
I am thinking something like a thin wall 5/16" or 1/4" tube, with 1" of
the tip turned up, flattened, and plugged up and a hole drilled.
Has anyone mounted a AOA on rudder?
Know where to buy one?
Made one?
Thx.

Hi Ron,
The AOA technique used by Dynon appears to be to measure the differential
pressure between the pitot tube port and an angled reference port in their
AOA probe. As the angle of attack changes so will the pressure
differential. So you would need two tubes (if using tubes) one aligned with
the longitudinal axis of the aircraft and one at an angle (I am not certain
but I think Dynon's angle port is at about 45 deg from the pitot port axis).
Since the Dynon system is set up for this angle difference in their
computation, it would be important to try to duplicate this angular
difference as close as possible. Also, the airflow around the tip of a tube
can result vortex generation as opposed to a hole drilled in a nominal
airfoil shaped probe which can cause pressure fluctuation. If I were to
choose to build my own probe for the Dynon system, I would attempt to copy
the Dynon probe as close as I could.
I have designed and built an AOA system using a similar approach - works on
the bench with a air blower but have not installed it in the aircraft as
yet.

The only problem you will have is that the Dynon requires their AOA Pitot to function as the AOA function requires a differential pressure variance to indicate the lift potential.
If you use the Dynon AOA Pitot tube it will only take care of the AOA function and you will still have to supply a separate static port for the other Dynon instrument functions.
