fastga.models.aerodynamics.components.wing.compute_cl_pitch_rate_wing module

class fastga.models.aerodynamics.components.wing.compute_cl_pitch_rate_wing.ComputeCLPitchVelocityWing(**kwargs)[source]

Bases: openmdao.core.explicitcomponent.ExplicitComponent

Computation of the contribution of the wing to the increase in lift due to a pitch velocity. The convention from [Ros85b] are used, meaning that, for the derivative with respect to a pitch rate, this rate is made dimensionless by multiplying it by the MAC and dividing it by 2 times the airspeed. The reference point for the CG was taken to be equal to the wing quarter chord to match what is taken for other coefficient. If another reference point is to be used, this coefficient should be multiplied by (1.0 + 4.0 * x_w / l0_wing) with x_w the distance between CG and wing quarter chord, negative when CG is in front of the wing quarter chord.

Based on [Ros85b] section 10.2.7

Store some bound methods so we can detect runtime overrides.

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)[source]

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.

compute_partials(inputs, partials, discrete_inputs=None)[source]

Compute sub-jacobian parts. The model is assumed to be in an unscaled state.

Parameters

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

  • partials (Jacobian) – Sub-jac components written to partials[output_name, input_name]..

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