Duncan B Cox Deceased

Title: Duncan B. Cox: Innovator in Helicopter Rotor Blade Technology

Introduction

Duncan B. Cox was a notable inventor based in Pittsburgh, PA, who made significant contributions to the field of aerospace engineering. His innovative work focused on enhancing the performance and durability of helicopter rotor blades.

Latest Patents

Cox held a patent for a strain-resistant heated helicopter rotor blade. This invention involved a unique process where wire is flat braided into a straight component on a braiding machine. Carrier threads were utilized to prevent deformation as the component was drawn off the machine. Once the carrier threads were removed, the braid component was cut into straight strips with terminals connected to the ends. The braid component, with leads extending from it, was then mounted to or integrated into the surface of a high strain aerodynamic component. Notably, the axis of the heater was designed to be parallel to the direction of applied stress, allowing the wires to lie along directions of reduced strain.

Career Highlights

Cox was associated with Cox & Company, Inc., where he applied his expertise in developing advanced technologies for the aerospace sector. His work not only showcased his innovative spirit but also contributed to the safety and efficiency of helicopter operations.

Collaborations

Cox collaborated with Martin Schuyler, who was a coworker and likely shared similar interests in aerospace innovations. Their partnership may have fostered an environment of creativity and technical advancement.

Conclusion

Duncan B. Cox's contributions to helicopter rotor blade technology exemplify the impact of innovation in aerospace engineering. His patented invention remains a testament to his ingenuity and dedication to improving aviation safety and performance.
