His work is characterized by a deep understanding of acoustic modes and their impact on machinery.

Latest Patents

Kushner's latest patents include a method and arrangement to minimize noise and excitation of structures due to cavity acoustic modes. This innovative arrangement is designed to intentionally mistune a cavity formed adjacent to an impeller in a turbomachine. It includes at least two bladed elements defined within a perimeter of a casing wall adjacent to the impeller. The configuration of these bladed elements aims to mistune cavity acoustic modes, thereby minimizing acoustic pulsations in the cavity.

Another significant patent is the turbomachinery stationary vane arrangement for disk and blade excitation reduction and phase cancellation. This invention involves a turbomachine that features a plurality of rotating blades adjacent to stationary vanes attached to a stationary casing. The stationary vanes are spaced apart circumferentially with equal spacing around the inner perimeter of the casing. They may also be offset radially and/or circumferentially to enhance performance. The design includes tapered leading and trailing edge angles to homogenize flow and reduce various excitations caused by the interaction with spinning modes of acoustic pressure pulsations.
