Flops based hybrid powered turboprop aircraft battery builder

[jpaelu]

Hello
Im part of team trying to develop a hybrid electric turboprop aircraft concept using aviary. I saw in the discussion posts that currently an electrified aircraft are incompatible with the 2DOF and i just wanted to clarify if it will work for a height energy based mission?
Assuming that is the case would it be possible to optimise a dual throttle setup (one combustion one electric) using the current aviary features or would this require creating our own external subsystem (or some other work around) for this?

Thankyou for any help it is greatly appreciated

Hi jpaelu, apologies for the very late reply. We've been actively working to get fully electric and hybrid electric aircraft working for every combination of subsystem methods and equations of motion, so things have been changing relatively quickly! Hybrid-electric and all-electric should work with both the energy and 2DOF methods, although we are still building our example models to showcase that capability.

If you are using engine decks to represent your dual-throttle engine, then you can use Aviary as-is. We have a hybrid-electric model that is currently only used for internal testing (so it is undocumented) you can take a look at as an example: https://github.com/OpenMDAO/Aviary/blob/main/aviary/models/aircraft/test_aircraft/aircraft_for_bench_FwFm_with_electric.csv.

That model only tests that electric power and fuel consumption both get tracked correctly, so it is missing some important features like a battery! The electric power is basically "free" and the aircraft is not meant to be realistic, which is why it only exists for testing purposes. Hopefully it is helpful!
