Latest Patents
One of his latest patents is titled "Oscillating air jets for reducing HSI noise." This invention utilizes porous surfaces on an aerodynamic structure, driven by positive and negative pressures, to create an active control system that attenuates shock waves responsible for high-speed impulsive (HSI) noise. The system features an array of apertures that allow fluid communication between the exterior flow stream and the interior volume of the structure. A movable diaphragm pushes air in and out through these apertures, generating oscillating air jets. The drive mechanism is actuated by a controller based on sensor information from the leading edge of the aerodynamic structure.
Another significant patent is "Blade vortex interaction noise reduction techniques for a rotorcraft." This invention introduces an active control device designed to reduce blade-vortex interactions (BVI) noise generated by rotorcraft, such as helicopters. It comprises a trailing edge flap located near the tip of each rotor blade, which is actuated in a scheduled manner during the rotor blade's rotation. This careful azimuth-dependent deployment and retraction of the flap weakens the blade tip vortices, which are the primary source of BVI noise, and pushes them farther away from the rotor disk.
