fastga.models.aerodynamics.components.compute_cn_beta module

class fastga.models.aerodynamics.components.compute_cn_beta.ComputeCnBetaAircraft(**kwargs)

Bases: openmdao.core.group.Group

Computation of the increase in yawing moment due to a sideslip angle. Assumes the coefficient at aircraft level can be obtained by summing the contribution of the individual components ( fuselage and VT). Wing contribution is negligible up until high angles of attack. The convention from [Ros85b] are used, meaning that for lateral derivative, the reference length is the wing span. Does not take into account the effect of nacelles or propeller lateral forces.

Based on [Ros85b] section 10.2.4.1

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.
