Error Handling¶
The following custom errors are defined in PyProp
-
class
pyprop.MaxCurrentExceededError(component_type, component_name, I_max, I_drawn)¶ An error thrown when the max current that can be handled by one of the components is exceeded.
-
component_type¶ The type of component (“motor”, “ESC”, or “battery”).
Type: str
-
component_name¶ The name of the component.
Type: str
-
I_max¶ The maximum current allowed through the component.
Type: float
-
I_drawn¶ The amount of current trying to be drawn.
Type: float
-
-
class
pyprop.ThrottleNotFoundError(error_type, v_cruise, T_req, final_val=None)¶ An error that occurs when the solver for the throttle value does not converge or the throttle value determined is not possible.
-
error_type¶ The type of error. Either “not_converged” or “throttle_invalid”.
Type: str
-
v_cruise¶ The cruise velocity in ft/s.
Type: float
-
T_req¶ Required thrust in lbf.
Type: float
-
final_val¶ The throttle value converged to (if “throttle_invalid”).
Type: float
-
-
class
pyprop.TorquesNotMatchedError(v_cruise, throttle)¶ An error that occurs when the propeller and motor torques cannot be matched at a speed.
-
v_cruise¶ Cruise velocity in ft/s.
Type: float
-
throttle¶ Throttle value.
Type: float
-
-
class
pyprop.InvalidRuntimeError(runtime)¶ An error that occurs when a negative runtime is predicted.
-
runtime¶ The predicted runtime in minutes.
Type: float
-
-
class
pyprop.DatabaseRecordNotFoundError(command)¶ “An error which occurs when the user tries to pull a record from the database which does not exist.
-
command¶ The sql command which failed.
Type: str
-
-
class
pyprop.PropDataBoundsError(prop, rpm, J)¶ “An error which occurs when the computation falls outside the range of the experimental data for the prop.
-
prop¶ The name of the prop.
Type: str
-
rpm¶ The rpm value which exceeded the data.
Type: float
-
J¶ The advance ratio which exceeded the data.
Type: float
-
-
class
airfoil_db.DatabaseBoundsError(airfoil, exception_indices, inputs_dict)¶ An exception thrown when the inputs to the airfoil database fall outside the database bounds.
-
airfoil¶ The name of the airfoil for which this exception occurred.
Type: str
-
inputs_dict¶ The arguments passed to the airfoil.
Type: dict
-
exception_indices¶ The indices at which the arguments fell outside the database bounds.
Type: list
-
message¶ A message about the error.
Type: str
-
