effect of ribs position on aerodynamic behavior
effect of ribs position on aerodynamic behavior
(OP)
Hello everyone,
I was wondering what is the effect of ribs position on a wing on the aerodynamic behavior and especially on the aeroelastic behavior. Does the position of ribs can change the dynamic behavior for a flutter phenomena for example.
I am not an expert in aircraft design so I do not know how the space between ribs is calculated it's just a question that came to me while talking with a colleague.
Hope someone have a point on this topic.
Have a nice day

RE: effect of ribs position on aerodynamic behavior
I guess there may be some affect on stiffness, I mean there'd probably be a difference if you went to the extreme (say rib spacing = b/2), but between normal rib spacings I'd've thought that'd be small.

The plane then sounds like a flying collection of trash cans.

You are judged not by what you know, but by what you can do.
RE: effect of ribs position on aerodynamic behavior
In most cases this oil canning would probably just cause a slight increase in drag and change in properties of the aerofoil like stall angle, pitch moment... probably relatively inconsequential.
However, depending what surface it is on and where in the flight profile the A/C is it could conceivably be catastrophic.
Also could lead to fatigue issues.
