DEMONSTRATE - DEMonstration Of Novel fuSelage sTructuRAl inTEgrity
Overview
Objectives:
DEMONSTRATE will realise an adaptable test rig, suitable for the full-scale testing of aircraft curved panels of variable geometry, at increased accuracy, reliability and cost-efficiency, through the advancement of innovative metrology technologies, simulation and optimisation, as well as application of innovative but cost-effective methodologies to reduce uncertainty, cost and time on aeronautical sub-components testing.
The objective of DEMONSTARTE, aligned to the ‘Innovative light metallic and thermoplastic airframe section full scale testing’ (JTI-CS2-2020-CFP11-AIR-03-10) topic is the full-scale testing of three airframe section demonstrators, two metallic and a thermoplastic fuselage panel with an integrated stiffening structure, to demonstrate their structural integrity, supported by advanced simulation methodologies correlated with experimental data.
Methodology:
A number of enabling technologies have been planned to be developed and matured within the duration of the project, which will result in the realisation of an efficient, reliable, and cost-effective test bench suitable for the full-scale testing of curved aeronautical panels, including:
- the development of a virtual testing methodology for the definition of the stiffened panels boundary and loading conditions;
- the further development of an innovative, cost-efficient, easily adaptable fuselage panel full-scale test bench concept;
- the development and/or adaptation of a wide range of novel measurement techniques; and
- the development and application of advanced simulation methodologies.
The developed test bench will be used for the execution of static tests on advanced metallic and thermoplastic curved integrally stiffened full-scale panels, representative of a business jet fuselage structure and the execution of an endurance test on an integrally stiffened 4th generation Al-Li curved panel.
