SLIDE 2

Function of Ribs

Maintain aerodynamic profile

f wing

Transfer aerodynamic & fuel loads on skin to structure Provide stability against panel buckling

SLIDE 3

Function of Ribs

Introduce local load into the structure

i.e. landing gear, engines,

flaps, ailerons, etc Sealing the integral fuel tank

Fuel surge/splashing

SLIDE 4

Function of Ribs

No ribs: Crushing Not enough ribs: Buckling Rib pitch: Typically 0.2 - 1 m

SLIDE 5

Selection of Ribs & Manufacturing Method

Depends on:

Loads
Design philosophy
Available equipment and

experience

Costs

SLIDE 6

Types of Ribs & Manufacturing Method

Form & plate ribs

Stiffening profile
Low loads

Forged or machined ribs

Very high loads

SLIDE 7

Rib-stringer intersections

Three general solutions: – Both rib and stringer not interrupted – Stringer interrupted – Rib interrupted
