Options for propulsion model #376

Open vinx012 opened 3 years ago

vinx012 commented 3 years ago

Hello,

Is there a way to pass a variable from the configuration file to the propulsion module? Just to be more specific, imagine I want to pass the "bypass_ratio" variable of the "RubberEngine" class as an option of the perfomance module. Is this possible?

In my case I have a variable that triggers the choice of the fidelity level of the propeller model to be used in my turboprop_engine class. I'd like this variable to be an option in the configuration file.

Thanks, Vincenzo

Hello,

indeed, the mechanism of propulsion wrapper does not allow to pass options from configuration file, unlike the standard modules. That would be a nice feature to add, I guess. In the meantime, the workaround is to do the choice at compute() time, on the basis of variable values, but I understand it may be not satisfactory.

That is the workaround I've been using but I think being able to do it from the configuration file would make much more sense. I've tried to find a solution, but I couldn't find a nice and proper way to do it.
