Planar vibrating airfoilcould this idea work?

Click For Summary
The discussion revolves around a proposed concept for a planar vibrating airfoil that could enable vertical take-off, hovering, and multi-directional flight. The idea is based on Bernoulli's Principle, suggesting that oscillating the airfoil could create lift by manipulating air pressure. However, participants express skepticism about the feasibility, noting that the oscillatory motion may not generate sufficient lift due to the complexities of airflow dynamics and the need for a stable pressure gradient. Concerns are raised about the airfoil's backward movement during oscillation, which could hinder lift generation. The conversation also touches on alternative methods, such as electrostatic airflow manipulation, but doubts remain regarding their practical effectiveness.

Regarding the OP's idea: rather than having the wings oscillate back and forth, why not just attach them to a central pivot point and rotate them around in a circle...?
