1. A computer-implemented method for determining vehicle noise physical characteristics, the method comprising:
defining a computer-based model of a vehicle capable of flight;
automatically determining aerodynamic performance and propulsion performance of the vehicle based on the defined computer-based model;
responsively performing a flight-dynamics simulation of the vehicle using the determined aerodynamic performance and propulsion performance, wherein performing the flight-dynamics simulation produces flight status data;
automatically and probabilistically down-sampling the flight status data to generate a reduced dataset;
performing a high-fidelity flow simulation of the vehicle using the reduced dataset, performing the high-fidelity flow simulation determining in-flight aerodynamic and aeroacoustic performance of the vehicle; and
based on the determined in-flight aerodynamic and aeroacoustic performance, determining noise physical characteristics of the vehicle and storing an indication of the determined noise physical characteristics in computer memory, wherein the performing a high-fidelity flow simulation and determining noise physical characteristics are automatically implemented by one or more digital processors.
