The concept is simple (implementation not). I can't imagine that this would be considered constrained compressed air. The only constraint is the inertia of the ball when fan creates pressure to move air and ball.
- The ball is loaded into the barrel and rolls to stops
- Fan motor is energized to a variable voltage (volts determine exit velocity)
- After ball leaves cannon, fan motor is de-energized
