Equipped with an 8-motor distributed power system, all motors operate independently during vertical takeoff and landing. The aircraft can maintain stable hovering and achieve safe emergency landing even if one single motor or propeller malfunctions, meeting the strict safety standards of trunk civil aviation aircraft.
Benefiting from the compound-wing aerodynamic layout, the aircraft relies on multi-rotor systems for VTOL and fixed wings to generate lift during cruising. Compared with pure multi-rotor eVTOLs, it features lower stall risk and stronger crosswind resistance, perfectly adapting to complex airspaces such as urban canyons, mountainous regions and islands.
Developed in strict accordance with civil aviation airworthiness requirements, the airframe has passed ultimate static load tests and overload flight verifications to guarantee high structural reliability.
Constructed with more than 85% carbon fiber composites, the aircraft delivers lightweight performance, outstanding structural strength, excellent corrosion resistance and long fatigue service life, effectively reducing regular maintenance frequency compared with metal airframes.
Optimized with a bionic aerodynamic shape, it cuts energy consumption remarkably during cruising, delivering faster flight speed and longer range under the same maximum take-off weight with lower energy consumption per kilometer.
The self-developed fully enclosed air-cooled motors feature an IP67 protection rating, enabling stable operation in rainy, snowy and sandy environments for flexible vertiport deployment.
The versatile 500 kg payload supports quick switching between passenger and cargo missions. Ideal use cases cover urban air mobility, intercity short-distance transit, low-altitude tourism, medical emergency transportation, forest fire prevention, pipeline inspection and emergency material delivery to remote islands.
Operators can maximize fleet revenue via diversified operational scenarios.
The fully-electric propulsion system achieves zero local emissions with far lower flight noise than conventional helicopters, allowing compliant flights over urban core areas and residential zones.
It requires no long runways for vertical takeoff and landing, which can be deployed on rooftop landing pads or ordinary flat vertiports to slash upfront infrastructure investment.
This aircraft adopts high-voltage DC fast charging as the standard operational energy replenishment method rather than rapid battery swap between flight turns.
- Equipped with dedicated aviation fast chargers, the battery can be charged to 85% capacity within 30 minutes and fully charged in 45 minutes.
- Operators only need to deploy charging piles instead of costly automatic swap equipment and large-scale standby battery inventories, greatly lowering vertiport construction costs.
- Operators can also leverage off-peak industrial electricity prices to minimize energy expenditure.
The average power consumption ranges from 70 kWh to 82 kWh per 100 kilometers:
- Off-peak electricity cost: USD 28-33 per 100 km
- Peak electricity cost: USD 84-98 per 100 km
The per-seat energy cost is merely around one-tenth of the fuel expense of traditional helicopters, presenting prominent operational economic advantages.
The battery system accounts for approximately 28% of the total aircraft procurement cost. Under regular commercial operation with 3-4 flight segments per day, full battery replacement is required every 3 years on average.
Routine monthly inspections including visual check, flight control calibration and motor insulation test are mandatory, alongside heavy scheduled maintenance every 500 flight hours.
Free of internal combustion engines, lubrication systems and complicated transmission components, the aircraft has far fewer mechanical failure points. Combined with the corrosion-resistant carbon fiber airframe, the annual maintenance cost covering labor and spare parts is only 20% of that of conventional helicopters, accounting for 2.3%-3.2% of the aircraft's total purchase price.
Costs include professional pilots and certified maintenance technicians, aviation liability insurance (1.4%-1.9% of aircraft value annually), vertiport rental, charging facility maintenance and utility fees. Expenses can be significantly diluted via fleet scaling.
When deployed in large fleets, the comprehensive operating cost stands at USD 0.75-1.4 per seat per kilometer. The aircraft can generate stable positive profits with a daily flight duration of over 3.5 hours, making it highly competitive for air taxi and commercial low-altitude operation.
- The modular electrical architecture supports quick plug-and-play replacement of faulty components, securing an aircraft availability rate up to 99.7%.
- Equipped with IP67 air-cooled motors and corrosion-resistant composite fuselage, the aircraft boasts strong environmental adaptability and low failure rates in harsh regions.
- With self-developed core powertrain and avionics systems, spare parts enjoy stable supply, competitive pricing and short lead times.
- Overseas operators can further cut after-sales costs by building regional spare parts warehouses.
