_DynamicsRigidBodyBaseClass

Helper class that provides a standard way to create an ABC using
class aerosandbox.dynamics.rigid_body.common_rigid_body._DynamicsRigidBodyBaseClass(mass_props=None, **state_variables_and_indirect_control_variables)[source]#

Bases: aerosandbox.dynamics.point_mass.common_point_mass._DynamicsPointMassBaseClass, abc.ABC

Helper class that provides a standard way to create an ABC using inheritance.

Parameters:

mass_props (aerosandbox.MassProperties) –

property op_point[source]#

Returns an OperatingPoint object that represents the current state of the dynamics instance.

This OperatingPoint object is effectively a subset of the state variables, and is used to compute aerodynamic forces and moments.

property alpha[source]#

The angle of attack, in degrees.

property beta[source]#

The sideslip angle, in degrees.

property rotational_kinetic_energy[source]#

Computes the kinetic energy [J] from rotational motion.

KE = 0.5 * I * w^2

Returns:

Kinetic energy [J]

property kinetic_energy[source]#

Computes the kinetic energy [J] from translational and rotational motion.

KE = 0.5 * m * v^2 + 0.5 * I * w^2

Returns:

Kinetic energy [J]

abstract add_moment(Mx=0, My=0, Mz=0, axes='body')[source]#

Adds a moment (in whichever axis system you choose) to this Dynamics instance.

Parameters:

  • Mx (Union[float, aerosandbox.numpy.ndarray]) – Moment about the x-axis in the axis system chosen. Assumed these moments are applied about the center of mass. [Nm]

  • My (Union[float, aerosandbox.numpy.ndarray]) – Moment about the y-axis in the axis system chosen. Assumed these moments are applied about the center of mass. [Nm]

  • Mz (Union[float, aerosandbox.numpy.ndarray]) – Moment about the z-axis in the axis system chosen. Assumed these moments are applied about the center of mass. [Nm]

  • axes – The axis system that the specified moment is in. One of: * “geometry” * “body” * “wind” * “stability” * “earth”

Return type:

None

Returns: None (in-place)
