- Hydrogen-UAV designers comparing powertrain and mission assumptions
- Worth noticing
- Buffer-battery mass counts toward takeoff weight, but the current model does not count it as added usable mission energy.
Field notes
The input ledger separates non-energy mass, buffer-battery mass, hydrogen, and tank accessories; blank accessory mass remains unknown rather than being counted as zero. Power accounting is shown in four steps, while the mission workflow distinguishes airspeed from ground speed and records only executed samples. The page cautions that transient battery support, actual acceleration, and post-landing energy use are not fully represented.
