NOISE IMMISSION ASSESSMENT FOR A320 GROUND-BASED FLIGHT SIMULATOR

Kurzfassung

FH Aachen's A320 ground based flight simulator, i the AIXplane, is coupled to DLR's PANAM simulation tool in order to assess whole aircraft noise immission along virtual flights. All required operational input parameters for a PANAM noise simulation are extracted from the ground-based simulator, e.g., speed, altitude, configuration (high-lift and gear Operation), thrust setting, and more data. Additional parameters describing the required details of aircraft and engine design and performance for a noise prediction come from specific aircraft and engine simulation tools, In a first study, the AIXplane is applied to reproduce test flights from a large DLR flight campaign with an A320. Results of the virtual AIXplane flights are then directly compared to measured flight data from the campaign for validation purposes. The DLR campaign also included noise level measurements during the flight tests at multiple locations. The measured noise levels are then directly assessed versus the predicted noise levels based on both measured and simulated flights. The validity and reliability Of the overall simulation process can be confirmed, i.e., predicted noise immission levels along measured and simulated flights are in good agreement to measured noise levels. Ultimately, the novel process is applied to approach and departure test case flights generated by AIXplane, i.e., a noise immission assessment along these flights is realized and can be assessed. The paper presents the methodology and the overall setup, shows selected validation cases, and demonstrates its potential for a realistic application case. In a conclusion section of the paper, potential updates, improvements, and next steps are discussed. Furthermore, future research areas and potential application cases in the context of noise awareness training for pilots or Air Traffic Management are identified and discussed.
