Title: Innovations by Chris R Fuller in Aircraft Noise Control
Introduction
Chris R Fuller is an accomplished inventor based in Blacksburg, VA (US). He holds 2 patents that focus on innovative solutions for reducing aircraft engine noise. His work has significant implications for the aviation industry, particularly in enhancing passenger comfort and reducing environmental noise pollution.
Latest Patents
One of his latest patents is titled "Active control of aircraft engine inlet noise using compact sound." This invention presents an active noise control system that effectively reduces aircraft engine duct noise. The system utilizes an adaptive filtered-x LMS algorithm to control the fan noise from a turbofan engine. It employs single multi-channel control systems to manage the fan blade passage frequency (BPF) tone and its harmonics. Additionally, a multi-channel control system is designed to control both fan tones and a high-pressure compressor BPF tone simultaneously. The technology incorporates a compact sound source consisting of an array of identical thin, cylindrically curved panels. These panels are strategically mounted inside the inlet duct to minimize aerodynamic losses and prevent leakage. Each panel is driven by piezoelectric force transducers, maximizing the response when driven at its resonance frequency, typically between 2000-4000 Hz.
