Spring-in prediction capability for large integral wing structure [SAT]


Composite material manufacturing process induced deformation such as spring-in may cause severe tolerance challenges for the assembly of aero-structures. This phenomenon becomes a major issue for large complex structures such as an integral wing box. The objective of this topic is to provide an approach to be able to analytically predict the spring-in phenomenon for an integral 7 meter wing box structure. A small scale integral demonstrator (1.2-1.5m) manufactured by the topic leader will be used to help calibrate and verify the approach. Please refer to the full topic descriptions document published in this call.
