Trim

class sharpy.solvers.trim.Trim

Trim routine with support for lateral dynamics. It usually struggles much more than the StaticTrim (only longitudinal) solver.

We advise to start with StaticTrim even if you configuration is not totally symmetric.

The settings that this solver accepts are given by a dictionary, with the following key-value pairs:

Name	Type	Description	Default
print_info	bool	Print info to screen	True
solver	str	Solver to run in trim routine
solver_settings	dict	Solver settings dictionary	{}
max_iter	int	Maximum number of iterations of trim routine	100
tolerance	float	Threshold for convergence of trim	0.0001
initial_alpha	float	Initial angle of attack	0.0
initial_beta	float	Initial sideslip angle	0.0
initial_roll	float	Initial roll angle	0
cs_indices	list(int)	Indices of control surfaces to be trimmed	[]
initial_cs_deflection	list(float)	Initial deflection of the control surfaces in order.	[]
thrust_nodes	list(int)	Nodes at which thrust is applied	[0]
initial_thrust	list(float)	Initial thrust setting	[1.0]
thrust_direction	list(float)	Thrust direction setting	[0.0, 1.0, 0.0]
special_case	dict	Extra settings for specific cases such as differential thrust control	{}
refine_solution	bool	If True and the optimiser routine allows for it, the optimiser will try to improve the solution with hybrid methods	False
