Extract

When designing an aircraft structure, the structural engineer has to achieve given standards of airworthiness in respect of strength, stiffness and fatigue life while ensuring that the final weight is as low as possible to give operating economy or flexibility. At the same time he must ensure that a minimum of design effort is used, manufacture is as easy as possible, the serviceability is good, the aerodynamic shape is retained, aeroelastic effects minimised and so on. The structural engineer of today has to ensure that the fatigue life is satisfactory, together with the older concept of purely static strength, and if he has resorted to the use of fail safe principles he has to establish those characteristics as well.
