SHERLOC- ADVANCED TOOLS AND SYSTEMS FOR STRUCTURAL HEALTH DIAGNOSTICS OF ROTORCRAFT CRITICAL COMPOSITE COMPONENTS
is a partnership between Critical Materials S.A., PoAF-Portuguese Air Force, CEIIA and with the collaboration of OGMA, for the development of a new generation of systems for SHM-Structural Health Monitoring operations in aircrafts.
Research and development in the field of structural health monitoring and non-destructive inspection of critical composite aeronautical components.
The SHERLOC project consists of research, development and functional testing of advanced tools for the diagnosis of the structural integrity of composite components of rotary wing aircraft. The project's end result the creation and validation of advanced aerostructures diagnostic tools composite components that, consider the whole life cycle, namely:
a) potential manufacturing defects (manufacturing quality);
b) structural loads applied to aircraft in mission;
c) its structural condition throughout their use in service;
d) structural condition inspection and maintenance operations.
In the context of the SHERLOC project, several innovative techniques and methodologies will emerge, namely:
i. NDI-Non Destructive Inspection technique based on the EMI-Electromechanical Impedance measurement for the detection of defects and damages in composites for:
a. quality control of the manufacturing process of composite components,
b. detecting damage during inspection and maintenance operations;
ii. Advanced NDT technique for the diagnosis of structural damage (detection, location and damage severity estimation);
ii. Advanced SHM technology for the assess of structural condition, testing it during service, with flight data;
iv. Integration of NDT tools and SHM techniques in a single structural condition evaluation tool.
