INTRODUCTION

As already described, different sizes and types of aircraft need different

construction. This applies to the mainplanes, or wings, as much as to any other

part. Each wing is basically made up of two parts – the internal structure, such

as spars and ribs, and the skin, which can be of fabric, metal or composites –

although the distinction between structure and skin may not be readily

apparent in modern fast jets or large transport aircraft.

SPARS, RIBS, STRINGERS AND SKIN

Wings are made up of large number of components, even with integrally

machined structures, but the structural part consists of main types of

component:

Spars

Most of the lift, and hence shear force, that occurs on the wing is collected

together into spars. Spars run spanwise, in other words from the root (where

the wing is attached to the fuselage) to the tip. Most wings contain two spars

– the front and rear spars – but it is quite common for wings to have more than

this. This is particularly so with swept wings on transport aircraft, which often

have a short spar, the auxiliary spar or kick spar, which helps to support the

undercarriage, and provides a location for the inboard flaps.
