mass_rate

This module provides the functionality for creating mass rate settings.

Functions

from_thrust([use_all_thrust_models, ...])	Creates the settings for a mass rate model defined from a thrust model.
custom(mass_rate_function)	Creates the settings for a mass rate model defined from a thrust model.

from_thrust(use_all_thrust_models: bool = 1, associated_thrust_source: str = '') → tudatpy.kernel.numerical_simulation.propagation_setup.mass_rate.MassRateModelSettings

Creates the settings for a mass rate model defined from a thrust model.

Creates the settings for a mass rate model defined from a thrust model. The mass rate model is derived from the associated body’s engine model. It is possible to consider only a specific engine or all engines.

Parameters

• use_all_thrust_models (bool, default=true) – Denotes whether all engines of the associated body are to be combined into a single thrust model.

• associated_thrust_source (str, default="") – Name of engine model from which thrust is to be derived (must be empty if the first argument is set to true).

Returns

From thrust mass rate settings object.

Return type

FromThrustMassRateSettings

custom(mass_rate_function: Callable[[float], float]) → tudatpy.kernel.numerical_simulation.propagation_setup.mass_rate.MassRateModelSettings

Creates the settings for a mass rate model defined from a thrust model.

Creates the settings for a custom mass rate model defined through a mass rate function. The function must have time as an independent variable.

Parameters

mass_rate_function (callable[[float], float]) – Function of time defining the custom mass rate.

Returns

Custom mass rate settings object.

Return type

CustomMassRateSettings

Enumerations

Classes

MassRateModelSettings	Functional base class to define settings for mass rates.
FromThrustMassRateSettings	MassRateModelSettings-derived class to define settings for a mass rate model derived from a thrust model.
CustomMassRateSettings	MassRateModelSettings-derived class to define settings for a custom mass rate model.

class MassRateModelSettings

Functional base class to define settings for mass rates.

Base class for providing settings for a mass rate model, that defines the models to be used to numerically propagate the mass of a body during a simulation. If any additional information (besides the type of the mass rate model) is required, these must be implemented in a derived class (dedicated for each mass rate model type).

class FromThrustMassRateSettings

MassRateModelSettings-derived class to define settings for a mass rate model derived from a thrust model.

MassRateModelSettings-derived class to define settings for a mass rate model derived from a thrust model.

class CustomMassRateSettings

MassRateModelSettings-derived class to define settings for a custom mass rate model.

MassRateModelSettings-derived class to define settings for a custom mass rate model.
