Trevarthen says the company can now deliver complex geometries while simultaneously achieving double-digit cost and throughput improvements.

Dowty has developed six prototype propeller blades. Now that research through DigiProp is complete, the next step is to move these demonstration products into tests and designs for future aircraft.

Through close collaboration with the U.K.’s National Composites Centre, the DigiProp research program led to development of a new manufacturing process that uses a combination of bladder molding and triaxial braiding of CFRP composites.
