EmDrive & AwDrive - Wind Speed Measurements

AwDrive = Acoustic Wave Drive, The Analog of Electromagnetic Drive
How It Works.

[MidiMusicKH]

Output Wind Velocity V = 2.A.S.f/s (m/s)
Reaction Force F = 4.δ.A².S².f²/s (Newton)
---
For ether environment example:
A = 9 mm
R = 4.75 cm
r = 1.50 cm
f = 60 gHz = 60 * 10^9 Hz, ---
Ether output speed V = 2.A.S.f/s
= m/s
= 10830000 km/s

I think it is just pushing the air, why not to use a fan instead?
