Washout - Twist in VariEze wing

Recommended Posts

The LEZ and Cozy identify the amout of Washout (twist) in the wing on the wing drawing ....

On the Cozy - Chapter 19 - page 10 ....

 

Drawing shows .6 degrees washin at the strake interface and 2.7 degress washout at the wing's tip.

 

If you have a drawing of the VariExe's wing - could you please share what Burt identified as those values.

Thanks.

 

I have that document and have studied it.

 

It does not state the amount of washout.

 

The wing section has the following statement:

 

Tip Incidence, deg = -1.8

 

I take that as a measurement of the actual aircraft - not the design criteria.

 

If that is correct, then the VariEze had a washout of 1.8 degrees and the LEZ/Cozy has a washout of 3.3 degrees over it's wing span.

 

Does anyone know what the design criteria was?

The Long-EZ wing design is different than the Vari-Eze.

The Long-EZ was the basis for the Cozy design.

This would explain the difference between them.

It does not state the amount of washout.

Sure, it does. Root incidence and tip incidence are both given. Washout is 3 degrees.

could you elaborate ? will that change the water line ?

can you see the 3.3 or can it be measured?
