Battery Mass vs Jet-A Physics

Aircraft Total Weight 25,000 lbs (11.3 t)

Wingspan (Aspect Ratio) 106 ft (High L/D)

Pack Energy Density 265 Wh / kg

Jet-A Specific Energy 12,000 Wh / kg

Motor Powertrain Eff. 94% (Electric)

Turboprop Thermal Eff. 31% (Brayton)

Because battery mass does not burn off during flight, high-aspect 106-ft wings and four distributed electric propellers are essential to sustain minimum induced drag at 25,000 lbs.
