Department of Navy Jet Noise Reduction Project Overview
Abstract
High performance military aircraft represent the single largest noise source for Sailors on board aircraft carriers resulting in health issues, compromised operations and costly litigation. Unfortunately, tactical aircraft have not been able to leverage much of the available significant noise reduction technologies from commercial aircraft due to their low bypass ratio jet engines and resulting high temperature, high velocity exhaust streams. Tactical aircraft noise remains a problem from both community noise and personnel exposure perspectives. In response to the problem and recent Senior Leadership direction, the Office of Naval Research initiated the Jet Noise Reduction (JNR) Project as part of the Noise-Induced Hearing Loss (NIHL) Program. The JNR Project's over-arching objective is to realize and transition significant jet noise reduction technologies through coordinated S&T efforts. This objective will be accomplished through establishing a sustained S&T effort in fundamental jet noise understanding, predictive capability and measurement/validation capability and through developing, demonstrating and transitioning jet noise reduction technologies in support of the Warfighter and the Community. In fiscal year 2010, initial funding was allocated to support the basic program structure and for the two main tasks given high priority- developing a physics-based understanding of jet noise and developing standards to facilitate high quality jet noise measurements. An overview of the JNR Project will be presented as well as some preliminary results and a strategic outlook.
