plot_longitudinal_stability#
- plot_longitudinal_stability(results, save_figure=False, show_legend=True, save_filename='Longitudinal_Stability', file_type='.png', width=11, height=7)[source]#
Creates a multi-panel visualization of longitudinal stability characteristics.
- Parameters:
results (Results) –
- RCAIDE results data structure containing:
- segments[i].conditions.frames.inertial.time[:,0]
Time history for each segment
- segments[i].conditions.aerodynamics.angles.theta[:,0]
Pitch angle history
- segments[i].conditions.aerodynamics.angles.alpha[:,0]
Angle of attack history
- segments[i].conditions.control_surfaces.elevator.deflection[:,0]
Elevator deflection history
- segments[i].tag
Name/identifier of each segment
save_figure (bool, optional) – Flag for saving the figure (default: False)
show_legend (bool, optional) – Flag to display segment legend (default: True)
save_filename (str, optional) – Name of file for saved figure (default: “Longitudinal_Stability”)
file_type (str, optional) – File extension for saved figure (default: “.png”)
width (float, optional) – Figure width in inches (default: 11)
height (float, optional) – Figure height in inches (default: 7)
- Returns:
fig
- Return type:
matplotlib.figure.Figure
Notes
- Creates visualization showing:
Pitch attitude response
Aerodynamic angle evolution
Longitudinal control inputs
Trajectory angle history
Time history for each segment
- Major Assumptions
Angles are in degrees
Time is in minutes
Positive deflections follow right-hand rule
Definitions
- ‘Pitch Angle’
Nose-up/down attitude relative to horizon
- ‘Angle of Attack’
Angle between velocity vector and body reference line
- ‘Flight Path Angle’
Angle between velocity vector and horizon
- ‘Elevator Deflection’
Pitch control surface position
