SixDOF Landing Gear¶
The landing gear block defines the landing gear on a rigid_body_vehicle_type. The main components of landing_gear are ground_reaction_point objects.

This specifies the name of the steering control surface (when NWS is not engaged/active).
- nws_angle_control_surface_name <string>¶
This specifies the name of the steering control surface (when NWS is engaged/active).
- is_nose_gear <boolean-value>¶
This indicates whether or not this ground_reaction_point is a nose gear.
- braking_control_surface_name <string>¶
This specifies the name of the braking control surface. If unspecified, no braking is provided for this ground_reaction_point.
- gear_extended_relative_position_x <length-value>¶
This is the x-location (in object coordinates) of the bottom of the landing gear (or contact point) when extended.
- gear_extended_relative_position_y <length-value>¶
This is the y-location (in object coordinates) of the bottom of the landing gear (or contact point) when extended.
- gear_extended_relative_position_z <length-value>¶
This is the z-location (in object coordinates) of the bottom of the landing gear (or contact point) when extended.
- gear_compression_vector_x <real-value>¶
This is the x-direction (in object coordinates) of the compression vector.
- gear_compression_vector_y <real-value>¶
This is the y-direction (in object coordinates) of the compression vector.

This is the z-direction (in object coordinates) of the compression vector.
- gear_rolling_vector_x <real-value>¶
This is the x-direction (in object coordinates) of the rolling vector.
- gear_rolling_vector_y <real-value>¶
This is the y-direction (in object coordinates) of the rolling vector.
- gear_rolling_vector_z <real-value>¶
This is the z-direction (in object coordinates) of the rolling vector.
- spring_constant_lbs_per_ft <real-value>¶
This is the spring constant in lbs/ft.
- damper_constant_lbs_per_fps <real-value>¶
This is the damper constant in lbs/(ft/sec).
- uncompressed_length <length-value>¶
This is the uncompressed length of the landing gear.
- max_compression <length-value>¶
This is the maximum length of compression.
- rolling_coefficient_of_friction <real-value>¶
This is the rolling coefficient of friction.
- braking_coefficient_of_friction <real-value>¶
This is the braking coefficient of friction.
- scuffing_coefficient_of_friction <real-value>¶
This is the scuffing coefficient of friction.
- ignore_friction <boolean-value>¶
This indicates if friction should be ignored.
- is_landing_gear <boolean-value>¶
This indicates if the ground_reaction_point is a landing gear (true) or a contact point (false).
- is_contact_point <boolean-value>¶
This indicates if the ground_reaction_point is a contact point (true) or a landing gear (false).
