Imagine: an aircraft, like a bamboo dragonfly as light takeoff, but has far more than the multi-rotor UAV safety and load capacity; it is quiet enough to shuttle between urban buildings, energy consumption is much lower than traditional electric aircraft; it does not need a runway, precision landing on the roof or the field... This is not science fiction, but based on the mature rotating rotor technology of electric rotating rotor aircraft concept design!

Core design concept: simplify, safety first
Wingless lightness, self-rotating lift: Abandon the fixed wing completely, three non-powered self-rotating rotors are the only source of lift. The structure is greatly simplified, the weight is significantly reduced, and the core of safety is: even if the power fails completely, it can automatically enter stable gliding (lift-resistance ratio ≈ 4:1)! Safety redundancy far exceeds multi-rotor drones.

Electric silent, independent propulsion: the tail high power density motor drives a three-blade low-noise propeller (diameter 1.4m), without mechanical coupling with the rotor. Specially designed for electric optimization of the blade design, combined with the rotor low speed characteristics, the overall noise is 15-20 dB lower than the traditional helicopter, to meet the most stringent urban environmental protection requirements.
Vertical take-off and landing, accurate control: rely on the hybrid tilt system to achieve vertical take-off; use the full-motion rudder surface in front of the propeller (propeller slip flow enhancement) and rotor cycle variable pitch control to achieve pitch, yaw, roll and zero speed soft landing without runway!

High efficiency and energy saving, convenient maintenance: the rotor has no power loss, and the cruise power consumption is only 60-70% of the same level of electric helicopters. There is no complex transmission spindle and tail rotor system, the failure point is reduced by 40%, and the maintenance cost is significantly reduced. The modular battery (50 kWh) supports hot-swappable replacement and fast charging to ensure high-frequency tasks.
Target Performance & Wide World:
• Maximum takeoff weight: 600 kg
• Cruising speed: 120 km/h
• Flight time: 90 minutes (with 15% contingency reserve)
• Rotor diameter: 8.5 m
Core application scenarios:
Urban air traffic (UAM): vertical take-off and landing + extreme silence, perfect for short commuting between buildings and air taxis.
• Emergency material delivery: no runway, accurate landing in the field, disaster areas, roofs and other complex environment, race against time.
Environmental monitoring/agricultural operations: low noise characteristics have little impact on the environment, suitable for fine operation tasks.
