fastoad.models.performances.mission.base module

Base classes for mission computation.

class fastoad.models.performances.mission.base.AbstractFlightSequence[source]

Bases: fastoad.models.performances.mission.base.IFlightPart

Defines and computes a flight sequence.

compute_from(start: fastoad.base.flight_point.FlightPoint) → pandas.core.frame.DataFrame[source]

Computes a flight sequence from provided start point.

Parameters

start – the initial flight point, defined for altitude, mass and speed (true_airspeed, equivalent_airspeed or mach). Can also be defined for time and/or ground_distance.

Returns

a pandas DataFrame where columns names match FlightPoint.labels

abstract property flight_sequence

Defines the sequence as used in compute_from().

Returns

the list of IFlightPart instances for the mission.

class fastoad.models.performances.mission.base.AbstractManualThrustFlightPhase(*, propulsion: fastoad.models.propulsion.propulsion.IPropulsion, reference_area: float, polar: fastoad.models.performances.mission.polar.Polar, thrust_rate: float = 1.0, name='', time_step=None)[source]

Bases: fastoad.models.performances.mission.base.AbstractFlightSequence, abc.ABC

Base class for climb and descent phases.

Initialization is done only with keyword arguments.

Parameters

  • propulsion –

  • reference_area –

  • polar –

  • thrust_rate –

  • time_step – if provided, this time step will be applied for all segments.

class fastoad.models.performances.mission.base.IFlightPart[source]

Bases: abc.ABC

compute_from(start: fastoad.base.flight_point.FlightPoint) → pandas.core.frame.DataFrame[source]

Computes a flight sequence from provided start point.

Parameters

start – the initial flight point, defined for altitude, mass and speed (true_airspeed, equivalent_airspeed or mach). Can also be defined for time and/or ground_distance.

Returns

a pandas DataFrame where columns names match FlightPoint.labels
