Maneuvers

.. code:: python

    from scipy.constants import kilo
    
    from orbital import earth, KeplerianElements, Maneuver, plot

Here, we define an orbit and then plot it with several different
maneuvers applied.

**Note:** Plotting an orbit with a maneuver doesn't apply the maneuver
to the original orbit.

.. code:: python

    orbit1 = KeplerianElements.with_altitude(1000 * kilo, body=earth)

.. code:: python

    man1 = Maneuver.set_apocenter_altitude_to(10000 * kilo)
    plot(orbit1, title='Maneuver 1', maneuver=man1)

.. code:: python

    man2 = Maneuver.set_apocenter_radius_to(22000 * kilo)
    plot(orbit1, title='Maneuver 2', maneuver=man2)


.. image:: output_6_0.png


.. code:: python

    man3 = Maneuver.set_pericenter_radius_to(6800 * kilo)
    plot(orbit1, title='Maneuver 3', maneuver=man3)


.. image:: output_7_0.png


.. code:: python

    man4 = Maneuver.set_pericenter_altitude_to(500 * kilo)
    plot(orbit1, title='Maneuver 4', maneuver=man4)


.. image:: output_8_0.png


.. code:: python

    man5 = Maneuver.change_apocenter_by(1000 * kilo)
    plot(orbit1, title='Maneuver 5', maneuver=man5)


.. image:: output_9_0.png


.. code:: python

    man6 = Maneuver.change_pericenter_by(-500 * kilo)
    plot(orbit1, title='Maneuver 6', maneuver=man6)


.. image:: output_10_0.png


.. code:: python

    man7 = Maneuver.hohmann_transfer_to_altitude(10000 * kilo)
    plot(orbit1, title='Maneuver 7', maneuver=man7)


.. image:: output_11_0.png


To apply a maneuver, simply use the following method:

.. code:: python

    orbit1.apply_maneuver(man7)
    
Now orbit can be plotted to show its new state:

.. code:: python

    plot(orbit1, title='Applied Maneuver')
