Europa-List: Re: The Obsidian Files - Wing Tips

Some additional supporting images showing employment of a similar version of 
the EL500 style wing tip on a Bushcat STOL  aircraft.

Again something similar also found on a Globe Swift. Notice the leading edge 
slots. This will be addressed in another chapter of the obsidian files.

And some velocity flow images of the EL150 and EL2000 style wing tips showing 
the extended span of Lift generating area further out toward the tip. The 
EL2000 version is unique in experiencing a small dead spot at about 75% span 
that the other versions do not suffer.

Another forward profile view of the EL150 wing tip. It is this thinning of the 
bead between top and bottom chord that reduces the size of tip vortex, and the 
oval form that maintains  reduced vortex size through higher AoA's.

Finally EL2950 velocity flow images showing the outer extremities of the wing 
maintaining laminar flow during both high AoA and On Stall attitudes.
