NEW APPROACHES FOR THE DYNAMIC RECORDING OF AIRCRAFT NOISE AS A BASIS FOR MODELING

摘要

Airport operators face pressure to reduce the noise of their operations. A proactive approach is to use computer models to predict aircraft noise and identify lower noise alternatives. The more precise the input data used, the better the simulation. In recent years, the Swiss Federal Laboratories for Material Testing and Research (EMPA) has developed an advanced SonAir aircraft emission model. It allows aircraft noise emissions to be calculated as a function of the aircraft's type, position, orientation and configuration (e.g. thrust setting). The development challenges included: 1. Precise synchronizing with GPS time 2. Autonomous energy management 3. COMPLETE REMOTE CONTROL AND ADMINISTRATION With precise synchronization of noise and aircraft data, it is possible to determine noise data for each flight angle, distance and operating state of the aircraft as input to the SonAir model, Figure 1. The collaboration in this project enables EMPA to characterize multiple aircraft types in a variety of flight modes at a reasonable cost.
