Latest Patents

One of her latest patents is titled "Contoured Flexure Strap for Helicopter Rotor System." This invention relates to an improved helicopter rotor system that includes a contoured flexure strap with a simplified geometrical configuration. The flexure strap connects the rotary hub assembly with the rotor blades and is constructed from fiberglass. The primary load-carrying fibers of the flexure strap are designed to extend in the same direction as the spanwise axis, enabling it to withstand the centrifugal forces acting on it. The inboard end of the flexure strap features two separate ends, allowing for overlapping on opposite sides of the rotary hub assembly, secured by a single pin and bolt assembly. Additionally, a cloth wrap of composite matrix material surrounds parts of the flexure strap to prevent delamination during helicopter operation.

Another significant patent is a "Method of Making a Leading Edge Weight Retention Assembly for Helicopter Rotor Blades." This method involves wrapping a prepreg strap around the conical or cylindrical outboard end of each weight segment. The weight segment is then placed in the rotor blade spar and undergoes the spar cure cycle. Primary retention is achieved through adhesive bonding between the weight and the spar, while secondary retention is provided by hoop tension in the strap.
