Deployable structures have made an immense impact in the engineering world. The concept of the deployable structure has been able to reduce costs and sizing limits across a variety of use cases. However, sizing and cost reduction are not the only reasons that deployable structures are prominent. There are unique propeller blades that have entered into the world of deployable structures, where the ability to be stowed away and deployed to a much larger diameter can increase launch flexibility, and the engine efficiencies of aircraft. Although, most of the deployable propeller blades that have been designed in studies have the usual hinge mechanism where the down side of a hinge is that it does not necessarily provide any stiffness nor does it change the diameter of the propeller blade when stowed away. However, an unique strategy, that uses the underlying principle of snap through buckling can help to negate the use of hinges. This principle allows the propeller blade itself to be folded and stowed away, where stored strain energy is used in order to self-deploy back into the original shape. This paper will present an overall approach to the structural architecture development, conceptual prototype fabrication, and computational analysis of a foldable propeller blade.
