Subject: Finite Element Analysis on BS BRD blades V5, V6, and simplified rectangular blade 

Basis structural analysis was completed on models of the V5, V6, and a simple rectangular version of the BS BRD blades. The modesl were simplified to remove the glue layers. The models include stress analysis for individual layers of the blades, stress analysis for the entire blade, and a linearized stress analysis to examine stress discontinuties within the cross-section of the blade. The stresses analyzed include equivalent, maximum principle, and normal stress. The total deformation was also examined in the models. 

There is also attached an excel summary of the results of the models. 

The initial resuts of these models suggest that there is increased structural weakness in the V6 blade as opposed to the V5 blade. However, the results do not match with theorhetical stress analysis for the blades, so further analysis must be completed to refine the accuracy of the models.
