Title: Innovations of James R Zisson in Laser Shock Peening Technology
Introduction
James R Zisson is an accomplished inventor based in Salem, MA, known for his significant contributions to the field of gas turbine engine technology. He holds a patent for a method that enhances the durability and performance of rotor blades through laser shock peening. This innovative approach addresses the challenges faced in treating the leading and trailing edges of integrally bladed rotors.
Latest Patents
Zisson's patent, titled "Laser shock peening integrally bladed rotor blade edges," presents a method for applying laser shock peening to rotor blade edges that are not obstructed by other rows of blades. The technique involves continuously firing a stationary laser beam that produces repeatable pulses at consistent intervals. The laser beam is directed at an oblique angle to the surface of the blade edges, creating overlapping elliptical-shaped laser spots. In the exemplary embodiment, these spots have an overlap of approximately 50% and measure about 11.7 mm by 4 mm in diameter. Additionally, Zisson developed a method for laser shock peening rotor blade edges that are blocked by other rows of blades, utilizing a compound angle for the laser beam to achieve effective treatment.
