Hi,
I am planning to simulate a hexacopter drone. I am a bit confused about the way drag coefficient is calculated. In a sample .sdf simulation code there is a parameter called "rotor_drag_coefficient". This value is used in the calculations of 4 rotors in the detailed sample code with .xacro extension.
Front left Rotor drag_coefficient,
Front right Rotor drag_coefficient,
Back left Rotor drag_coefficient,
Back Right Rotor drag_coefficient
These values are the same in the code. I would like to know how drag coefficient is calculated for a multicopter? Is a there a single value for the platform shape as a whole? Or drag coefficients are calculated for each rotor separately? In my hexacopter example how can I proceed with this parameter?
Thanks in advance.
