Latest Patents

Kibens' latest patents include an "Apparatus to reduce thrust oscillations in a launch vehicle." This invention features a launch vehicle comprising a casing, a solid propellant, a channel, a geometric feature, and a suppression structure. The solid propellant is strategically located within the casing, while the channel runs through the solid propellant. The geometric feature is positioned in the channel, and the suppression structure is situated around the centerline of the channel, upstream in the flow path from the geometric feature.

Another significant patent is the "High frequency excitation apparatus and method for reducing jet and cavity noise." This active noise suppression apparatus aims to reduce jet engine noise and buffeting. It incorporates a plurality of resonant cavities formed in a structural member adjacent to a jet engine exhaust nozzle. Each resonant cavity opens toward an output slot, and a compressed air chamber supplies a pressurized, supersonic jetstream airflow through the inlet port into the resonant cavity. This innovative design generates a high frequency, pulsed, excitation airstream that modifies the shear layer of the exhaust airflow, leading to a substantial reduction in noise and buffeting.
