Bernuoli's principle states that as a fluid moves over an airfoil the pressure above it is less than the pressure below causing a net lift. It does not matter if the fluid flows from left to right...or from right to left. It would seem possible therefore to move the airfoil itself relative to the fluid back and forth at a high enough frequency to approximate a speed greater than the stall speed of the wing/load combination....This would seem to create lift. Push - Pull solenoids could move the airfoil 1/4" side to side at 4.32 KHz to approximate a 60 mph relative airspeed to airfoil (stall speed of a small plane)
Re: If an airfoil is vibrated horizontally, will it creat lift?
