Every whistle and recorder I've ever seen, has the airflow coming out of the windway, entering the window area and approaching the blade exactly in a line parallel with the linear length of the tube.
How did you measure this? I mean, otherwise you can’t simply “know” the airstream is directed exactly as you describe.

Has anyone experimented with this? Adjusted the windway angle approaching the blade? Adjusted the windway angle and the blade edge position? Anything work out? No doubt there is only a tiny angle variation available to work with, it would require precision work trying things out.
Yes, recorder makers have experimented with this over the years.
