SHERLOC (Structural HEalth Monitoring, Manufacturing and Repair Technologies for Life Management Of Composite Fuselage, Cleaksky II, coordinated by Imperial, 9.6M€). The overall objective of the proposed project SHERLOC is to combine advanced Structural Health Monitoring (SHM) and smart repair technologies with a probabilistic design philosophy, and hence to develop new maintenance concepts to reduce the direct operative costs without lowering the operational safety of a composite fuselage, as set out in call JTI-CS2-CPW1-AIR-02-03 Advanced Technologies for More Affordable Composite Fuselage.
The main four objectives of the project SHERLOC are:
- The design, manufacture and test of composite curved fuselage panel (5m), Flat Stiffened panel (1.6m), Window Frame, Floor Beam, Pressure Bulkhead aft and fittings, following a building block approach, and of structures with bonded repairs
- The development of advanced technical capabilities for making the integration of sensors in modern composite structures practical and efficient so as to facilitate industrialization and certification.
- The development of a methodology that comprises of advanced large scale modelling tools, validated by structural testing, which use/process the sensor signals to predict the residual strength of a damaged structure at the fuselage scale of a regional aircraft.
- The development and experimental validation of a probabilistic method to propose a robust design that leads to reduction of maintenance costs during service life and overall component cost.
