fastoad.models.geometry.profiles.profile module

Management of 2D wing profiles

class fastoad.models.geometry.profiles.profile.Coordinates2D(x, y)

Bases: tuple

Create new instance of Coordinates2D(x, y)

property x

Alias for field number 0

property y

Alias for field number 1

class fastoad.models.geometry.profiles.profile.Profile(chord_length: float = 0.0)

Bases: object

Class for managing 2D wing profiles :param chord_length: :param x: :param y:

chord_length: float

in meters

property thickness_ratio: float

thickness-to-chord ratio

set_points(x: Sequence, z: Sequence, keep_chord_length: bool = True, keep_relative_thickness: bool = True)

Sets points of the 2D profile.

Provided points are expected to be in order around the profile (clockwise or anti-clockwise).

Parameters

• x – in meters

• z – in meters

• keep_relative_thickness –

• keep_chord_length –

get_mean_line() → pandas.core.frame.DataFrame

Point set of mean line of the profile.

DataFrame keys are ‘x’ and ‘z’, given in meters.

get_relative_thickness() → pandas.core.frame.DataFrame

Point set of relative thickness of the profile.

DataFrame keys are ‘x’ and ‘thickness’ and are relative to chord_length. ‘x’ is from 0. to 1.

get_upper_side() → pandas.core.frame.DataFrame

Point set of upper side of the profile.

DataFrame keys are ‘x’ and ‘z’, given in meters.

get_lower_side() → pandas.core.frame.DataFrame

Point set of lower side of the profile.

DataFrame keys are ‘x’ and ‘z’, given in meters.

get_sides() → pandas.core.frame.DataFrame

Point set of the whole profile

Points are given from trailing edge to trailing edge, starting by upper side.
