Investigation of Failures in Aeronautical Engineering

Abstract

The result of structural failures of air frame, acro engines or propellors can be so serious that Aircraft and Aero Engine manufacturer take every precaution to minimise their possibility. Careful design and rigorous testing of all materials and parts is undertaken with this object in view. However, the rate of development in Aeronautical Engineering is so rapid that a new design may become obsolete even before it has passed the development stage and been put into production.Thus in many cases the final testing stage designs is still during its service and a certain number of failures show up in service life which could not be anticipated in the design or development stage . Fortunately the number of such failures is very small as is shown by the very high degree of reliability obtained from modern Aircraft and aero engines
