Have been noodling on a platform that would use a small high revving but quiet motor, some sort of rotary generator, a battery array, and a combination of electric motors.
My complete lack of understanding electrically in generator/alternator technology needs some guidance. So I was hoping someone could run through how to size a generator/alternator specification to a power source (internal combustion engine) and to a battery array and an electric motor for different mission profiles so I can play what ifs with available technology.
Right now I am trying to work backwards from existing electric prop drive motors like Joby and forward from existing generator technology like aviation and automotive light weight alternators/generators either 12v or 24v.
This could apply to both high efficiency aircraft and roadables.
My first pass is that you could put say 4 or more alternators on an accessory belt drive on the front of a small modern 2 stroke and get a ton of continuous output power for very little weight.
For now I am talking about only off the shelf stuff with maybe a custom power controller in between all the components to make it all work.
