PROGRESS ON AIRCRAFT INTEGRATED SAFETY HEALTH ASSESSMENT (AISHA)

摘要

The safe use of complex engineering structures such as aircrafts can only be guaranteed when efficient means of damage assessment are available. Whereas aircraft design is based nowadays on a damage tolerance approach and time-based inspection cycles, it is envisaged that the large cost associated with this approach can be drastically reduced by switching to a condition-based maintenance schedule. This does require continuous health monitoring capabilities using integrated sensing technology and autonomous damage assessment. This paper reports on the results of the European project AISHA (aircraft integrated safety health assessment) aiming at aircraft health monitoring technology by exploring the capabilities of ultrasonic Lamb waves as the basic sensing principle.
