I am ready to invest myself in any study that will be conducted towards better knowledge of the concept:
My knowledge acquired during 100+ hours of flights, as well as the raw and elaborated datas from 10-day wind-tunnel campaign can be shared free of charge.
In addition I can make my Glasair available, for flight tests of any modifications.
Following projects can be foreseen in wind tunnel:
1- Better knowledge of circulation through the W.V.E
2- Blowing a W.V.E stand alone to:
a- Determine if Poisseuille flow law, could apply?
b- Determine if a typical shapping of W.V.E trailling edge, can reach the Kutta condition?
3- Visualization with LDV (Laser Doppler Velocimeter)
4- FFT analyzer; I suspect an acoustic phenomenon.
5- To examine any suggestion
Foreseen program :
1- Test to be performed with more sophisticated analyzers to collect the data in different flights configurations.
2- Flies to be performed at high altitude where results should be more
significant. Since the equation for induced drag is:
Di = k*(2/P*rho*e)*(W/b)^2*(1/V), higher altitude has lower density (rho), and thus higher induced drag: consequently WVEs are more efficient in higher altitudes.
Concept application in other areas:
Helicopter and airplane blades
Electric windmill blades
Any lifting body that need rapidly dissipated trailing vortices ...
