Latest Patents

Coney holds a patent for the invention titled "Use of flow injection and extraction to control blade vortex interaction and high speed impulsive noise in helicopters." This active control device is designed to reduce high-speed impulsive (HSI) and blade vortex interaction (BVI) noise in rotor aircraft, such as helicopters. The system features a plurality of rotor blades that extend radially from a central hub. Each blade has upper and lower surfaces with an interior volume between them, along with leading and trailing edges. Air intake passages are strategically placed near the leading edge to allow controlled air admission into the interior volume, while air output passages near the trailing edge and outer edge tip enable controlled air expulsion. The system activates the admittance and expulsion of air based on the detection of BVI or HSI noise, effectively minimizing unwanted sound.
