The LRI process, especially for large scale structures, requires expensive ‘trial and error’ procedures and wide experience to get the correct infusion set-up. The high cost and risks involved often lead toconservative infusion designs with associated cost and performance penalties; or may lead to alternative, less competitive, manufacturing technologies and materials being adopted.

The development of accurate and efficient infusion simulation tools will contribute to properly develop and industrialize this technology. Two major technological challenges will be addressed in this project: the development of an innovative simulation model for the optimization of LRI processes for large stiffened wing stiffened panels and the generation of an in-depth understanding of the flow phenomena based in accurate experimental data.
