Structural Design Part II—Fail‐Safe Aspects

A Presentation of the Fail‐Safe Concept including the Design as it Applies to a Crack‐Free Life, Corrosion Prevention, Simplified Inspection and Repair, and Safety after Failure. IN designing a new aircraft structure, the principal concern is to ensure that structural failure docs not occur during any stage—taxying, taking‐off, climbing, cruising, descending, landing—of any flight. This concern is not only for the safety and well‐being of the travelling public but also for the economics of airline operation, since the operator demands a long working life from his aircraft, and a good re‐sale value.
