First Guidelines Created for Structural Health Monitoring of Commercial Aircraft
SAE International has created the first-ever industry guidelines for structural health monitoring (SHM) of commercial aircraft. The document—Aerospace Recommended Practice ARP6461: “Guidelines for Implementation of Structural Health Monitoring on Fixed Wing Aircraft”—was produced by an SAE technical committee consisting of the world’s leading aircraft manufacturers, systems and equipment integrators, regulators, airlines, and technical experts. The publication of the guidelines was the culmination of six years of work by SAE committee G-11SHM, which was launched by Stanford University professor Fu-Kuo Chang.
The guidelines detail the steps necessary to incorporate built-in sensors on aircraft that can monitor such operating conditions as load and stress, as well as the occurrence and extent of damage. Using advanced sensor technology will enable aircraft operators to improve maintenance practices and...
