Concept of the WAV

The WAV is an attempt to improve on the VeeBee in the construction method, and controlled flight glide path.

When I started to build this type of construction was to continue with the foam to generate the shape.  Keeping with the face concept whelped with cutting the shape, and hence a new shape emerged. This model was hand launched to identify if I was on tract. A discovery with the launches was similar to the launches done with the VeeBee. It had a tendency of dropping when the speed was reduce. So the Canard control surfaces where added after seeing the movie STEALTH. With the launches an improvement was noted, but not as reliable as predicted.

Here I began with exploring the structural frame design. Some good came out of this, using bamboo skews as the frame material.

The "A" frame is born.  Using the bamboo skews and resizing them to 1/16 dowels made it possible to build with. I also crated the Duct-Vanes at this scale 1/40.  I had a chance to use my magnet set to build with

The picture above are on the second version. Her is were I realized that the body foil was at a different angle of attack then the wings.  This definitely contributed in the dropping at lower speeds.  By raising the tail center I created a deceptive foil that would correct the angle of attack and add to the  V stabilizer. Also a closer look at the inlet was worked out on the third version.

In this process, I discover what may have prevented a steady glide path in my test flights.
The VeeBee has two type of airfoils built in.

• The body (lifting body)
• The winglets

The thicker body line represents the outer sides of the WAV body where the duct-vane is located.

At different speeds the foils react differently. With the VeeBee the two body foils share the same trailing edge, and behave with different angle of attack, not mentioning the winglets, this contributed to an unstable glide path.

So goes the theory.

In this diagram displays the correction used with the WAV. This will compensate for the different foils. The main (center) foil trailing edge is complimentary to that of the winglets, and sharing the same angle of attack.

The line up.  I is not with several tries that a good outcome is derived.

The final composition is happily concluded.   Now to build the flying model for testing 30"W x 29"L.
It is almost believable by just looking at it that it will fly.
