Title: Innovations of Paolo Graziosi in Jet Engine Noise Reduction
Introduction
Paolo Graziosi is a notable inventor based in Clifton Park, NY (US), recognized for his contributions to the field of jet engine technology. With a total of 8 patents to his name, Graziosi has made significant strides in reducing jet engine noise, enhancing both performance and environmental sustainability.
Latest Patents
Graziosi's latest patents include a method and system for the reduction of jet engine noise. This innovative method involves increasing air velocity adjacent to an inlet fan duct outer wall to a greater rate than the typical velocity of an operational engine's ambient inlet airflow. By reducing or eliminating boundary layer and associated turbulence, the refraction and absorption of inlet sound into an acoustic liner are optimized. Additionally, air velocity can be increased by injecting air or exerting a suction force. Another notable patent involves a system for jet engine noise control that features a thermal acoustic shield directed at a non-zero angle relative to the jet axis. This system enhances mixing in the main jet stream and creates a non-circular jet stream through the use of fluidic chevrons.
