Check jet engine weight and include in the calculation. One weights 2200-3700 lbs according to same source that quotes 45.9 seat miles per gallon. Vs 125 pounds for electric engine.
- tonyarkles 1mo agoI’d guess comparable for a 30-seat regional, you’d probably want to compare with a PT6, especially since this aircraft is prop driven. That’s only about 250lb dry.
- llukas 1mo agoIt seems you're right. Would nice to see breakdown for this plane how it actually maps to real world prototype.
- class3shock 29d agoThe thing I quoted is more for bigger jets with much larger engines (it was the first reasonable looking source I found). In any case their hybrid has four engines, two electric, two conventional, so you are really should think of it as needing to haul two extra engines on top of what a conventional only jet would have.
