Submodules

pytornado.fileio.cpacs.aircraft module

Functions for conversion of CPACS aircraft definition to native model

Developed at Airinnova AB, Stockholm, Sweden.

pytornado.fileio.cpacs.aircraft.get_aircraft_airfoils(aircraft, settings, tigl, wing_uid, segment_uid, idx_wing, idx_segment)

Extract the aircraft airfoils

Args:

aircraft:Aircraft model settings:Settings object tigl:Tigl handle segment_uid:Name of the segment idx_wing:Index of the wing idx_segment:Index of the segment

pytornado.fileio.cpacs.aircraft.get_aircraft_controls(aircraft, wing_uid, idx_wing, tixi, tigl)

Extract the controls surfaces

Args:

aircraft:Aircraft model wing_uid:Name of the wing idx_wing:Index of the wing tixi:Tixi handle tigl:Tigl handle

Warning

• CPACS3 changed the control surface defintions!
• In Tigl 3.0.0 some fuctions for controlSurfaces are missing (currently we use a workaround, see PATCH_* functions)
• In CPACS3 relative coordinates can be defined based on a ‘section’ or ‘componentSegment’, currently we assume the old definition (based on ‘componentSegment’)

pytornado.fileio.cpacs.aircraft.get_aircraft_name(aircraft, tixi)

Extract the aircraft name from CPACS and add it to the aircraft model

Args:

aircraft:Aircraft model tixi:Tixi handle

pytornado.fileio.cpacs.aircraft.get_aircraft_refs(aircraft, tixi)

Extract the aircraft reference values

Args:

aircraft:Aircraft model tixi:Tixi handle

Warning

• ‘rcenter’ is same as ‘gcenter’
• Currently there is only one reference length in CPACS

pytornado.fileio.cpacs.aircraft.get_aircraft_wing_segments(aircraft, settings, xpath_wing, wing_uid, idx_wing, tixi, tigl)

Extract a wing segment for a given wing

Args:

aircraft:Aircraft model settings:Settings object xpath_wing:CPACS wing path idx_wing:Wing index tixi:Tixi handle tigl:Tigl handle

pytornado.fileio.cpacs.aircraft.get_aircraft_wings(aircraft, settings, tixi, tigl)

Extract aircraft wings including airfoils and controls

Args:

aircraft:Aircraft model tixi:Tixi handle tigl:Tigl handle

pytornado.fileio.cpacs.aircraft.load(settings)

Get aircraft model from CPACS

Args:

aircraft:Aircraft model settings:Settings object

pytornado.fileio.cpacs.aircraft.write_airfoil_files(settings, tixi)

Extract airfoil data from CPACS and write airfoil files

Args:

settings:Settings object tixi:Tixi handle

pytornado.fileio.cpacs.results module

Write VLM results back to CPACS

Developed at Airinnova AB, Stockholm, Sweden.

pytornado.fileio.cpacs.results.save_aeroperformance_map(state, settings)

Write aeroperformance map results back to CPACS

Args:

state:(object) data structure for operating conditions settings:(object) data structure for execution settings

pytornado.fileio.cpacs.state module

Import of CPACS aeroperformance maps (flight states) and export of results

Developed at Airinnova AB, Stockholm, Sweden.

pytornado.fileio.cpacs.state.load(settings)

Load the flight state from the CPACS aeroperformance map

pytornado.fileio.cpacs.utils module

General CPACS functions

pytornado.fileio.cpacs.utils.XPATHS

alias of pytornado.fileio.cpacs.utils._XPaths

pytornado.fileio.cpacs.utils.add_vector(tixi, xpath, vector)

Add a vector at given CPACS path

Note:

• Values will be overwritten if paths exists

Args:

tixi:Tixi handle xpath:CPACS path vector:List or tuple (vector) to add

pytornado.fileio.cpacs.utils.close_tixi(tixi, cpacs_file)

Close Tixi and save to file

Args:

pytornado.fileio.cpacs.utils.get_segment_mid_point(tigl, idx_wing, idx_segment, eta, xsi)

Return a mid point for a segment

Args:

tigl:Tigl handle idx_wing:Wing index idx_segment:Segment index eta:Relative segment coordinate xsi:Relative segment coordinate

Returns:

mid_point:List with mid coordinate

pytornado.fileio.cpacs.utils.modify_cpacs(cpacs_file)

Context manganger for handling CPACS files

Args:

cpacs_file:CPACS file path

pytornado.fileio.cpacs.utils.open_tigl(tixi)
