Tool Development for Low-Noise Aircraft Design

The German Aerospace Center is developing a prediction tool named parametric aircraft noise analysis module (PANAM), which makes use of a noise component. Such models capture the major physical effects and correlations yet allow for a fast noise prediction. Parametric formulations enable prediction of the various effects on noise radiation caused by the variations of aircraft configuration and operating conditions throughout simulated flight operations. The PANAM framework allows for a straightforward integration of additional or updated noise source models reflecting progress in modeling the physics of noise source mechanisms and their parametrical dependencies. The modular setup allows for either self-contained operation or for direct integration in a multidisciplinary design code such as the code preliminary aircraft design and optimization (PRADO) developed at the Technical University of Braunschweig, Germany. The PRADO integration allows for fully automated low noise optimization of aircraft configurations in the preliminary design process.
