Research Institution
Safety, reliability, and life-cycle cost are of great concern to the aging aircraft manufacturing and maintenance industries. Acellent Technologies proposes to develop an accurate, reliable integrated system for detection, prediction and mitigation of aging and manufacturing related hazards in civilian and military aircraft. The objective of the proposed program will be to provide the U.S. Air Force with a Structural Health Monitoring (SHM) system for detection and quantification of degradation in aircraft structures specifically stress corrosion cracking. This information can then be transferred to the OEM's predictive models to provide predictions of remaining strength and life, thereby facilitating the development of maintenance strategies to mitigate the effects of the degradation on the aircraft safety and reliability. Most of the current structural health monitoring systems such as those based on vibration analysis focus on detecting the damage at component level and focus less on the failure of the material. Differing from these systems, Acellent’s system will use ultrasound Lamb waves from built-in sensor networks to sense the material change and detect micro-structural material changes. Phase I will focus on demonstrating feasibility of the system to detect stress corrosion cracking while phase II will focus on complete system development.
