F1 wind tunnel fan blade
ALFGAM Optimering AB has together with FlexProp AB and Fläkt Woods provided a wind tunnel for a formula 1 corporation. The structural design where performed by ALFGAM utilising the ROpt concept designing an optimal weight efficient fan blade.

The fan blade where designed as a strengthened sandwich structure with face of carbon fibres in an epoxy matrix on a PVC foam core. The integrated blade foot where designed in high strength steel.
The ROpt system where used to optimise the face thickness' in each part of the blade and minimise the weight of the blade while keeping the desired eigen-frequencies and strains.
