New Scientist Breaking News – ‘Singing’ wings help prevent small-plane stalls

—

The use of sound to increase the adhesiveness of the wings surface to air. Novel concept.

But can you see the effect if the amp(s) goes out while in low speed mode? Especially if they reduce the size of the wings the full 20+%. Need to make it mechanical and built as an inverse(?) harmonic of wind speed so the vibration increases as surface airflow decreases.

Quite an interesting concept. Makes me suspect some of the buzz produced by insect wings in hover mode are a variant of this concept.
