A little off topic, but I've been intrigued by the GA hybrid potential. Electric motor prop drive, enough batts to assist for takeoff and climbout, a gasoline, diesel or gas turbine driven generator. Two props, on wings or tail pods??
Advantage would be in safety, as the batts would allow much better landing options should generator fail.
I think the weight would be a killer using either piston engine, leaving the GT as best option.
GT's bsfc stink, but if optimized at one spot in the performance map, they seem to be "not so bad". On this rig, GT could be left operating at a very small region of the map. The weight saving may give fuel burn more of an advantage than the poor bsfc penalty detracts.
I have had a devil of a time finding out what the bsfc could be if optimized. There are APU's out there, and chopper turbines, but either bsfc data is not published or duty cycle is so different that it's an apples/oranges thing.
What do you guys think?
Total cost is probably a deal killer.
