Gents,

Downwash of the Simla?

Study picture of a downwash transmitter mounted on the LE of the stab of the Simla, next year.
for who is interested.

Dual pitot tube, dynamic pressure and static pressure port as normally.
The other two ports (1 and 2) for example under and angle of 45 degrees (to investigate). The pressure of these two ports is depending of the angle of attack but because the difference between these two pressure ports is also speed related I do need a second measurement to compare with and calculate a ratio and relationship. So speed.

The special amplifier is needed to generate a signal in “degrees” to Modis.

In several steps I want to try if this system can be used. A second method can be a rotating vane but damping can be a problem of that method.
