BUZCO
Rotor tested- Payload313 kg
- Endurance5 min at full payload
- Size6 m rotor
- Weight28 kg
- PowerJet fuel, tip turbines
A flying crane that rides to the job on a small truck.
- Lifts 11 times its own weight; DARPA asks for 4.
- No gearbox, tail rotor or swashplate: one fixed-pitch rotor.
- No pitch links to rig: rotor upkeep is just balancing the blades.
- Designed to cost about $175,000.
- Two people launch it where the load is.
For wildfire crews, disaster relief, construction, energy, offshore, farms and remote sites.
BUZCO: Blade-tip Uncrewed Zero-swashplate Cargo One-rotor. In Ukrainian, бузько is the stork. Legend says it was a man who let a sack of snakes escape, and gathers them still.
Technology
Why it is different
- Big props, few moving parts: direct-drive electric
- No swashplate: fixed-pitch blades
- Three 1 m prototypes built; one delivered to NASA Glenn
