The ARDA Flying wing v1.0
Advanced Reduced Drag Aircraft

The ARDA Flying Wing v1.0 is a light weight flying aircraft which uses an EHD (Electro-HydroDynamics) configuration based on the T.T. Brown effect for reducing significantly the air drag on the wings during the fly, this increases significantly the flight performances and generates a thrust during the flight
The wing surface is covered by a thin conductive layer ( a thin aluminum sheet ) and is connected to the
positive potential of the High Voltage Generator (+28kV). A thin wire, used as the negative electrode (connected to zero potential of the High Voltage Generator), is placed just in front of the leading edge of the ARDA Flying Wing and above the center line as shown in the diagram below ( for more informations see also the ARDA computer simulation)

The hydrostatic pressure induced by the non-uniform E-Field around the ARDA v1.0 Flying Wing is lower on the upper surface ( extrados ) than on the lower surface of the wing ( intrados ). This differential pressure due to the EHD Effect is the direct cause of the additionnal lift of the wing. The unbalanced low pressure on wing extrados produces an additional thrust, so an ARDA v1.0 Flying Wing is able to create its own lifting force and its own motional force...

Now, I can say that the ARDA Flying wing v1.0 works as the simulated model...

The ARDA Flying Wing v1.0 has been specialy designed for the EHD propulsion. The wings are aluminum covered, the fuselage is made of a non-conductive material (dielectric), only the nose is covered with aluminum. The wings are connected to High Voltage ( + 28kV ) and a thin copper wire placed in front of their leading edges is connected to the nose and to zero volt (or grounded). The leading edge of the wings is covered by a thin layer of dielectric (see below).

This model is a proof of concept mock-up, it aims at demonstrating force generation through the combination of the Biefeld-Brown Effect and a EHD regime.

Experimental test : The ARDA v1.0 Flying wing has been suspended with a nylon tether on its center of gravity. When the High Voltage is applied, the device begins to lift off and moves forward by itself SILENTLY at high speed. The resulting EHD thrust is undeniable (see the video below).

The ARDA Flying wing v1.0 is a simple demonstrator but it shows that the EHD propulsion is now a reality....
