Research, development and technical objectives to be achieved within the project scope and addressing JTI-CS2-2017-CFP06-AIR-01-26 main objectives may be summarised as:

  1. Experimental validation of different stiffener run-out configurations as a result of testing 6 general and 4 optimized configurations.
  2. Analysis of failure criteria based on results of the first experimental campaign. Therefore, generation of a prediction tool and methodology for the optimization of stiffener run-out. Finally, this objective will improve the reliability of optimization processes in stiffener run-out design.
  3. Up-scaling of the methodology developed for multi-stiffener panels’ optimization. Thus, the weight reduction expected for optimized multi stiffened panel is around 10%. Similar percentages apply to lead time improvement and cost reductions.
  4. Stiffener run-out design optimization using the methodology developed. Expectations about increasing run-out optimized configurations performance are around 20% higher.
  5. Demonstration of the methodology by experimental testing of optimized solutions and multi-stiffener panel to correlate results with predictions. Expectations of improving demonstration lead time and cost reduction raise to up to 50% because of using this methodology. This improvement is directly related to the lower number of configurations tested to validate a design with the new methodology.
