Use of Periodic Excitation to Enhance Airfoil Performance at Low Reynolds Numbers

Greenblatt and Wygnanski discuss a preliminary wind-tunnel investigation of an airfoil at typical MICRO air vehicle (MAV) Reynolds numbers, subjected to active control by periodic excitation. The investigation demonstrates that periodic excitation is markedly effective in the MAV Reynolds-number ran...

Zusammenfassung:	Greenblatt and Wygnanski discuss a preliminary wind-tunnel investigation of an airfoil at typical MICRO air vehicle (MAV) Reynolds numbers, subjected to active control by periodic excitation. The investigation demonstrates that periodic excitation is markedly effective in the MAV Reynolds-number range.
