The control of rocket fairing interior noise with a networked embedded system
Numerous investigations have been conducted with the purpose of attenuating the acoustic environment within rocket payload fairings. These, to date, theoretical and experimental laboratory studies have demonstrated a great deal of success. However, practical applications to this, and other large-scale noise control problems, have been limited in their success. These limitations are due to nonscalable control systems, weight constraints and comlexity. This work seeks to address these limitations by investigating the use of an array of networked embedded processors to control the interior acoustics of a rocket fairing. This networked embedded system consists of numerous computationally elements, paired with appropriate sensors and actuators, that communicate with each other over a wired or wireless network. The goal of the network is to minimize the interior acoustic level while expending a minimum amount of energy. Results from the simulation of such control system will demonstrate the effectiveness of such an approach. These results will also be compared with those obtained by traditional, centralized control architectures.

Abstract

Numerous investigations have been conducted with the purpose of attenuating the acoustic environment within rocket payload fairings. These, to date, theoretical and experimental laboratory studies have demonstrated a great deal of success. However, practical applications to this, and other large-scale noise control problems, have been limited in their success. These limitations are due to nonscalable control systems, weight constraints and comlexity. This work seeks to address these limitations by investigating the use of an array of networked embedded processors to control the interior acoustics of a rocket fairing. This networked embedded system consists of numerous computationally elements, paired with appropriate sensors and actuators, that communicate with each other over a wired or wireless network. The goal of the network is to minimize the interior acoustic level while expending a minimum amount of energy. Results from the simulation of such control system will demonstrate the effectiveness of such an approach. These results will also be compared with those obtained by traditional, centralized control architectures.
