Stiffened Panels

[awesomesash]

What do you mean by stiffened panel? and what are its functions in an aircraft?

 

[IRstuff]

Typically, it means that a panel was structurally reinforced and provides some sort of structural strength as its function.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

"stiffened panel" = a panel with stiffeners ...

there are many different reasons to stiffen a panel ... to help the panel carry axial loads (along the stiffeners) or bending loads; or to increase the shear allowable (using the stiffeners to break-up the panel, so called panel breakers).

I'd start with doing my own research (google "stiffened panels" or the like, read aircraft design textbooks (Michael Niu), and come back with a more specific question.

What shape does the panel have and in what capacity is it being made "stiffer"?

For example, a flat metal panel can be stiffened by adding flanges around its perimeter, by forming beads across its length/width, or by attaching structures such as ribs or stringers. A composite panel can be made stiffer by adding a honeycomb or foam core. Panels are often stiffened to increase their buckling capacity, or to alter their structural frequency to improve NVH characteristics.
