fastoad.models.performances.mission.segments.hold module

Class for simulating hold segment.

class fastoad.models.performances.mission.segments.hold.HoldSegment(*args, **kwargs)

Bases: fastoad.models.performances.mission.segments.base.RegulatedThrustSegment, fastoad.models.performances.mission.segments.base.FixedDurationSegment

Class for computing hold flight segment.

Mach is considered constant, equal to Mach at starting point. Altitude is constant. Target is a specified time. The target definition indicates the time duration of the segment, independently of the initial time value.

target: fastoad.model_base.flight_point.FlightPoint

A FlightPoint instance that provides parameter values that should all be reached at the end of compute_from(). Possible parameters depend on the current segment. A parameter can also be set to CONSTANT_VALUE to tell that initial value should be kept during all segment.

propulsion: fastoad.model_base.propulsion.IPropulsion

A IPropulsion instance that will be called at each time step.

polar: fastoad.models.performances.mission.polar.Polar

The Polar instance that will provide drag data.

reference_area: float

The reference area, in m**2.
