Simulation of aircraft noise sources enables noise considerations early in the design process when noise reduction concepts can still be easily included. Current empirical and semi-empirical methods rely on database, analytic analogies and simplified assumptions that do not take into account the full complexity of the aircraft noise generation mechanisms and the interaction between the various components. Even wind tunnel tests can only provide a limited assessment of simplified components and cannot easily assess the interaction between noise sources, e.g. landing gear/flap, and jet noise/wing at realistic conditions. Traditionally therefore, noise is evaluated conclusively during flight tests which is already at a late design phase and is associated with high costs and risks of late-design changes and potential delays.
SIMULIA’s aircraft community noise solutions on the 3DEXPERIENCE platform enable the assessment of noise from an entire aircraft in realistic flight conditions, taking into account all relevant airframe noise sources and including engine sources, and propagating the noise simulated in the near field to the ground to determine the environmental impact. We offer a complete, mature, world-class solution for this process on a single business platform, with an easy-to-use user interface, and with state-of-the-art solver technologies for fast and accurate simulations. Additionally, the tools are scalable and deployable to experts ranging from designers to engineers and to researchers.
