Airleron angle

Airleron angle

Airleron angle

(OP)
Hello,

does someone know where to find how the airleron angle is calculated?
I mean the maximum deflection of the airleron wich is needed.

Hi CastMetal,

thank you for this link! It is exactly what I was looking for.
I used google too, but only found very complicated instructions and a lot of mathematical stuff ;)

RE: Airleron angle

(OP)
I just have a question about the calculation of the airleron deflection angle.

Where do I get this data from?

1. Change in lift with aileron deflection: cldeltaa
2. Airfoil's lift curve slope: cldelta
3. Section drag coefficient: cdo

Is it possible to calculate them? Or do they come from flight tests?

RE: Airleron angle

1) dCl/da ... you should be able to estimate (calculate is too "hi' folutin'") similar to a simple T/E flap ... basic design texts (torenbeek, raymer) or Hoerner (sp?) "Fluid Dynamic Lift"

airfoil Cl is generally available (for the wing airfoil and the aileron airfoil; also Cd.  look up the airfoil data (maybe on the NACA/NASA site).
