Vertical tail lift coefficient estimation.

Based on : Roskam, Jan. Airplane Design: Part 6-Preliminary Calculation of Aerodynamic, Thrust and Power Characteristics. DARcorporation, 1985. Equation (8.22) applied with the geometric characteristics of the VTP and an effective aspect ratio different from the geometric one obtained as described in section 10.2.4.1.

Store some bound methods so we can detect runtime overrides.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Declare inputs and outputs.

Available attributes:

name pathname comm options

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)

Compute outputs given inputs. The model is assumed to be in an unscaled state.

Parameters

• inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

• outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

• discrete_inputs (dict or None) – If not None, dict containing discrete input values.

• discrete_outputs (dict or None) – If not None, dict containing discrete output values.
