I devised a simple test to get some clues about this theory. I ran a 1" x 12" air stream at fairly high velocity (100mph or so) with a 1/8" plate ground down to a knife edge and held the knife edge in front of the airstream with the plate parallel to the direction of the air flow. It did...
Could the principle of Edge Tone used to create a frequency in the airflow of a musical instrument such as the recorder be used to impart a frequency on a much larger air stream? Ideally I would use it in something in the range of a 24" diameter fan with around 130 mph velocity and...
Thanks for the explanation! I'm actually trying to impart a vibration by the oscillation of the green bars, so this is the motion I was hoping to get. If I understand correctly, I could get less sweep out of the green bars by shortening the red bars or by lengthening the green bars (or both)?
I've simplified my question to make it easier to explain; I'm trying to find a way to determine the motion of a freely turning body as resultant of 2 counter-weights on rotating arms.
Here's my write-up:
