Package Contents¶

class aerosandbox.dynamics.point_mass.point_1D.DynamicsPointMass1DHorizontal(mass_props=None, x_e=0, u_e=0)[source]¶

Bases: aerosandbox.dynamics.point_mass.point_3D.cartesian.DynamicsPointMass3DCartesian

Dynamics instance: * simulating a point mass * in 1D, oriented horizontally (i.e., the .add_gravity() method will have no effect)

State variables:: x_e: x-position, in Earth axes. [meters] u_e: x-velocity, in Earth axes. [m/s]
Control variables:: Fx_e: Force along the Earth-x axis. [N]

Parameters:

mass_props (aerosandbox.weights.mass_properties.MassProperties) –
x_e (Union[float, aerosandbox.numpy.ndarray]) –
u_e (Union[float, aerosandbox.numpy.ndarray]) –

mass_props¶

For each state variable, self.state_var = state_var

For each indirect control variable, self.indirect_control_var = indirect_control_var

For each control variable, self.control_var = 0

x_e = 0¶

y_e = 0¶

z_e = 0¶

u_e = 0¶

v_e = 0¶

w_e = 0¶

alpha = 0¶

beta = 0¶

bank = 0¶

Fx_e = 0¶

Fy_e = 0¶

Fz_e = 0¶

property state: Dict[str, float | aerosandbox.numpy.ndarray]¶

Returns the state variables of this Dynamics instance as a Dict.

Keys are strings that give the name of the variables. Values are the variables themselves.

This method should look something like:

>>> {
>>>     "x_e": self.x_e,
>>>     "u_e": self.u_e,
>>>     ...
>>> }

Return type:: Dict[str, Union[float, aerosandbox.numpy.ndarray]]

property control_variables: Dict[str, float | aerosandbox.numpy.ndarray]¶

Return type:: Dict[str, Union[float, aerosandbox.numpy.ndarray]]

state_derivatives()[source]¶

A function that returns the derivatives with respect to time of the state specified in the state property.

Should return a Dict with the same keys as the state property.

Return type:: Dict[str, Union[float, aerosandbox.numpy.ndarray]]
