class suboptimumg.vehicle.aerodynamics.aerodynamics.Aero(vehicle_model)[source]#

Bases: object

Parameters:

vehicle_model (VehicleModel)

drs_disabled_override()[source]#

Force DRS off for the duration of a with block.

Return type:

Generator[None, None, None]

drs_is_active(drs_threshold)[source]#

Check whether DRS is currently active, honoring the disable override.

Parameters:

drs_threshold (float) – Current lateral acceleration threshold (m/s^2)

Returns:

True if DRS is equipped, not overridden off, and within threshold.

Return type:

bool

get_drag(v, drs_threshold)[source]#

Calculates the drag force based on the current velocity. Varies the output based on the DRS active state.

Returns:

Drag force (N)

Return type:

float

Parameters:

  • v (float)

  • drs_threshold (float)

get_lift(v)[source]#

Calculates the lift force based on the current velocity without DRS.

Returns:

Lift force (N)

Return type:

float

Parameters:

v (float)

tire_lift_forces(v, drs_threshold, pitch=None, roll=None)[source]#

Calculates the lift force on each tire based on the current velocity. Varies the output based on the DRS active state.

Returns:

Front and rear lift forces on each tire (N)

Return type:

tuple

Parameters:

  • v (float)

  • drs_threshold (float)

  • pitch (float | None)

  • roll (float | None)
