[002]~ Aeroelastically tailored blades
~~~ Using composites of glass fibers and graphite fibers fused with epoxy,
~~~ Howard is developing rotor blades that are "aeroelastically tailored":
~~~ Layers of fibers are placed upon more layers in a cross-stitch type of pattern,
~~~ strengthening the blade in any direction of motion.
~~~ By changing the orientation of the fibers, she can control how the blades bend and twist in flight
