The PoLaRBEAR (Production and Analysis Evolution For Lattice Related Barrel Elements Under Operations With Advanced Robustness) project focuses on reliable novel composite aircraft structures based on geodesic technology aiming at a significant higher Robustness and Technology Readiness Level (TRL).While the global structural behavior of composite geodesic structures is investigated and understood in a top-down approach in EU-ALaSCA, PoLaRBEAR will follow up in a bottom-up approach on local level analyzing the geodesic structures in terms of in-operation demands for higher TRL.The main objectives of this research proposal are:• Industrial highly automated process for cost efficient barrel manufacturing• Advanced reliability of geodesic structures under operational loads• Design rules for robust grid structuresThe aim is to promote a competent cooperation in the development of light, low-cost airframe fuselage structures made with a new generation of composite materials and based on geodesic / iso-grid technologies under operations.The proposal will enhance the cooperation in research and in innovation between the European Union and the Russian Federation in the field of civil transport aircraft.
