Today’s design and certification procedures of aircrafts are mainly based on conservative static loading which leads to additional weight and, potentially, to a structurally unsafe aircraft. The overall objective of the DAEDALOS project is to develop methods and procedures to determine dynamical loads considering the effects of dynamic buckling, material damping and mechanical hysteresis during aircraft service. Use of advanced analysis and design principles from DAEDALOS will partly remove the uncertainty and the conservatism of today’s design and certification procedures. DAEDALOS work will hence form the basis for improved common design practices by: 1. Determining accurate dynamic load spectra to be used for structural sizing. 2. Reducing the added weight of aircraft structural components due to conservative design in compliance with quasi-static loads by using more realistic equivalent dynamic loads. This goal will be achieved through improved introduction of the structure damping capacity and detailed analysis. 3. Increasing structural safety using more realistic loading scenarios. 4. Establishing new procedures for the definition of loads to be used during aircraft design and certification by authorities
