Noise Reduction for Military Airfields and Surrounding Areas

AVID proposes to develop software that determines takeoff and landing operational parameters for advanced military aircraft that result in trajectories that reduce noise in populated areas surrounding military airfields. This software will utilize GIS technologies to make the analysis site-specific for a given airfield and to automate the input. The project will make use of AVID’s suite of aircraft modeling and simulation tools, and build on noise methodologies that have been developed in the government over many years. A direct approach to optimization of flight trajectories and aircraft controls will be taken and both gradient-based and genetic-algorithm optimization methodologies will be employed to determine the set of operational parameters which reduce a cost function based on perceived noise level at observer stations on the ground.
