fastga.models.aerodynamics.components.compute_cn_roll_rate module

class fastga.models.aerodynamics.components.compute_cn_roll_rate.ComputeCnRollRateAircraft(**kwargs)

Bases: openmdao.core.group.Group

Computation of the increase in yaw moment due to a roll rate. Assumes the coefficient at aircraft level can be obtained by summing the contribution of the individual components. Some of these computations depend on the aircraft flying conditions, see the warnings in each file. The convention from [Ros85b] are used, meaning that for lateral derivative, the reference length is the wing span. Another important point is that, for the derivative with respect to yaw and roll, the rotation speed are made dimensionless by multiplying them by the wing span and dividing them by 2 times the airspeed.

Based on [Ros85b] section 10.2.6

Set the solvers to nonlinear and linear block Gauss–Seidel by default.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Build this group.

This method should be overidden by your Group’s method. The reason for using this method to add subsystem is to save memory and setup time when using your Group while running under MPI. This avoids the creation of systems that will not be used in the current process.

You may call ‘add_subsystem’ to add systems to this group. You may also issue connections, and set the linear and nonlinear solvers for this group level. You cannot safely change anything on children systems; use the ‘configure’ method instead.
