Computing noise contours

This example shows how to compute ground level noise contours around an existing trajectory.

import os
import pdb
import numpy as np
import openmdao.api as om
import pandas as pd
import matplotlib.pyplot as plt

os.environ["pyna_language"] = 'python'
from pyNA.pyna import pyna

# Load default pyna settings
pyna_settings = pyna.load_settings(case_name = 'nasa_stca_standard')
pyna_settings.save_results = True

# Compute noise contours
x_lst = np.linspace(0, 15000, 5)
y_lst = np.linspace(0, 4000, 2)
py = pyna(settings=pyna_settings)
py.compute_noise_contours(x_lst=x_lst, y_lst=y_lst)

# Plot
py.plot_noise_contours()
