compute_rotor_noise(microphone_locations, rotor, segment, settings, rotor_index=0, previous_rotor_tag=None, identical_propulsors=True)

This is a collection medium-fidelity frequency domain methods for rotor acoustic noise prediction which computes the acoustic signature (sound pressure level, weighted sound pressure levels, and frequency spectrums of a system of rotating blades

Assumptions: None

Source: None

Inputs:

rotors - data structure of rotors [None] segment - flight segment data structure [None] results - data structure containing of acoustic data [None] settings - accoustic settings [None]

Outputs:

Results.

blade_passing_frequencies - blade passing frequencies [Hz] SPL - total SPL [dB] SPL_dBA - dbA-Weighted SPL [dBA] SPL_1_3_spectrum - 1/3 octave band spectrum of SPL [dB] SPL_1_3_spectrum_dBA - 1/3 octave band spectrum of A-weighted SPL [dBA] SPL_broadband_1_3_spectrum - 1/3 octave band broadband contribution to total SPL [dB] SPL_harmonic_1_3_spectrum - 1/3 octave band harmonic contribution to total SPL [dB] SPL_harmonic_bpf_spectrum_dBA - A-weighted blade passing freqency spectrum of
