Title: Hormoz Tadghighi: Innovator in Rotorcraft Noise Reduction

Introduction

Hormoz Tadghighi is a notable inventor based in Scottsdale, AZ, who has made significant contributions to the field of rotorcraft technology. He holds a total of four patents, focusing on innovative solutions to reduce noise and vibration in rotorcraft systems. His work is particularly relevant in the aerospace industry, where noise reduction is a critical concern.

Latest Patents

One of his latest patents is titled "Tapered/segmented flaps for rotor blade-vortex interaction (BVI) noise and vibration reduction." This invention involves an active control device designed to minimize BVI noise generated by rotorcraft, such as helicopters. The device features a segmented trailing edge flap located near the tips of the rotor blades, which can be independently actuated based on specific operating conditions. This innovative approach effectively weakens blade tip vortices, which are the primary source of BVI noise, and increases the separation distance from the rotor disk, resulting in a quieter operation.

Another significant patent by Tadghighi is "Oscillating air jets for reducing HSI noise." This invention utilizes porous surfaces on an aerodynamic structure, driven by positive and negative pressures, to attenuate shock waves responsible for high-speed impulsive (HSI) noise. The system includes an array of apertures that allow fluid communication between the exterior flow and the interior of the structure. A movable diaphragm creates oscillating air jets, which are controlled based on sensor feedback, enhancing the aerodynamic performance and reducing noise levels.
