fastoad.models.performances.mission.segments.registered.taxi module

Classes for Taxi sequences.

class fastoad.models.performances.mission.segments.registered.taxi.TaxiSegment(name: str = '', target: fastoad.model_base.flight_point.FlightPoint = <object object>, isa_offset: float = 0.0, propulsion: fastoad.model_base.propulsion.IPropulsion = <object object>, polar: Optional[fastoad.models.performances.mission.polar.Polar] = None, polar_modifier: fastoad.models.performances.mission.polar_modifier.AbstractPolarModifier = UnchangedPolar(), reference_area: float = 1.0, time_step: float = 60.0, maximum_CL: Optional[float] = None, altitude_bounds: tuple = (-500.0, 40000.0), mach_bounds: tuple = (-1e-06, 5.0), interrupt_if_getting_further_from_target: bool = True, engine_setting: fastoad.constants.EngineSetting = EngineSetting.CLIMB, thrust_rate: float = 1.0, true_airspeed: float = 0.0)

Bases: fastoad.models.performances.mission.segments.time_step_base.AbstractManualThrustSegment, fastoad.models.performances.mission.segments.time_step_base.AbstractFixedDurationSegment

Class for computing Taxi phases.

Taxi phase has a target duration (target.time should be provided) and is at constant altitude, speed and thrust rate.

polar: fastoad.models.performances.mission.polar.Polar = None

The Polar instance that will provide drag data.

reference_area: float = 1.0

The reference area, in m**2.

time_step: float = 60.0

Used time step for computation (actual time step can be lower at some particular times of the flight path).

true_airspeed: float = 0.0

get_gamma_and_acceleration(flight_point: fastoad.model_base.flight_point.FlightPoint) → Tuple[float, float]

Computes slope angle (gamma) and acceleration.

Parameters

flight_point – parameters after propulsion model has been called (i.e. mass, thrust and drag are available)

Returns

slope angle in radians and acceleration in m**2/s

compute_from_start_to_target(start: fastoad.model_base.flight_point.FlightPoint, target: fastoad.model_base.flight_point.FlightPoint) → pandas.core.frame.DataFrame

Here should come the implementation for computing flight points between start and target flight points.

Parameters

• start –

• target – Definition of segment target

Returns

a pandas DataFrame where column names match fields of FlightPoint

property target: fastoad.model_base.flight_point.FlightPoint

The base class of the class hierarchy.

When called, it accepts no arguments and returns a new featureless instance that has no instance attributes and cannot be given any.
