Descrizione del progetto
Un dispositivo di prova per pannelli curvi della fusoliera
Il progetto DEMONSTRATE, finanziato dall’UE, ha come obiettivo lo sviluppo di un dispositivo di prova adattabile utile a testare pannelli curvi di aerei a grandezza naturale di geometria variabile, con elevata precisione e a basso costo. Nell’ambito del progetto saranno applicate tecniche avanzate di metrologia, simulazione e ottimizzazione che consentono di risparmiare tempo e costi sui collaudi di sotto-componenti aeronautici. In particolare, l’obiettivo è testare l’integrità strutturale di tre dimostratori di sezione della cellula, due pannelli di fusoliera metallici e uno termoplastico con una struttura di irrigidimento integrata. Il banco di prova di nuova concezione sarà utilizzato per eseguire test statici su pannelli curvi metallici e termoplastici avanzati, rappresentativi delle strutture della fusoliera dei business jet, e test di resistenza su un pannello curvo in Al-Li di quarta generazione integralmente irrigidito.
Obiettivo
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.
A number of enabling technologies have been planned to be developed and matured within the duration of the project, which will result to 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; 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.
