aero_fileplot

aero_fileplot#

Generates 3-D surface plots of an AeroDatabase — one figure for stability derivatives and one for control derivatives at a reference beta.

Plot AeroDatabase tables as 3-D surface plots (port of aero_fileplot.m).

avl_aero_tables.aero_fileplot.aero_fileplot(aero, beta_ref=0.0)[source]#

Plot stability and control coefficient tables from an AeroDatabase.

Produces two sets of figures:

Stability figure — 2×3 grid of 3-D surface plots showing each of the six total-force coefficients vs. alpha and beta.
Control figures — one figure per coefficient, each containing one subplot per control surface, showing the coefficient vs. alpha and deflection at beta_ref.

Parameters:

aero (AeroDatabase) – AeroDatabase built by aero_filewrite().
beta_ref (float) – Sideslip angle (deg) at which control-surface subplots are sliced. The nearest available beta breakpoint is used.

Returns:

Stability figure first, then one control figure per coefficient. Returns an empty list for any set that cannot be plotted (e.g. no control surfaces).

Return type:

list[plt.Figure]

Example

>>> from avl_aero_tables import avl_sweep
>>> from avl_aero_tables.aero_filewrite import aero_filewrite
>>> from avl_aero_tables.aero_fileplot import aero_fileplot
>>> results = avl_sweep(
...     "examples/bd.avl",
...     alpha=[-5, 0, 5, 10],
...     beta=[-5, 0, 5],
...     ctrl_sweeps={"elevator": [-10, 0, 10]},
... )
AVL sweep complete → ...  (36 cases)
>>> db = aero_filewrite(results)
>>> figs = aero_fileplot(db)
>>> len(figs)  # stability + one figure per coefficient
7
>>> figs[0].get_suptitle()
'Stability coefficients'
>>> figs[1].get_suptitle()
