The YUAV Y37 is a long endurance VTOL drone built for the new generation of industrial missions. It represents the latest advancement in long-endurance VTOL fixed-wing UAV design. As industrial applications increasingly rely on electric VTOL drones for mapping, LiDAR survey, powerline inspection, and long-range monitoring, the Y37 delivers a rare combination of efficiency, payload capacity, and regulatory compliance under 20 kg MTOW. It offers the long-range cruise performance of a fixed-wing aircraft while retaining the operational convenience of vertical takeoff and landing, making it a highly capable platform for teams needing a professional long-distance drone for large-area data acquisition.
Industrial operators today often require more than basic mapping capabilities. High-resolution 170 mm EO/IR gimbals, lightweight LiDAR units close to 2.4 kg, multi-sensor payloads, and long-range data links have become standard expectations.
To meet these evolving needs, the YUAV Y37 uses a new aerodynamic wing, a larger 3.7-meter wingspan, and a redesigned fuselage with significantly more internal volume. This allows the aircraft to carry heavier mission equipment without sacrificing endurance or stability.
While the earlier 3-meter YUAV Y30 platform gained popularity for its simplicity and solid mapping performance, the Y37 moves into a higher performance class designed for extended missions and heavier payloads. Key improvements include:
- Larger wingspan: 3.7 m improves lift and lowers cruise power consumption.
- Higher payload capability: 2–4 kg for professional gimbals and LiDAR modules.
- Expanded fuselage: wider nose and longer rear bay for easier equipment integration.
- Increased battery + payload load: up to 12 kg combined capacity.
- Significant endurance increase: tested up to 8.5 hours.
- Greater aerodynamic efficiency: more than 40% lift-to-drag improvement.
For operators upgrading from the YUAV Y30, the Y37 offers substantial gains in flight time, payload options, internal space, and mission efficiency,
while still remaining within the crucial sub-20 kg regulatory class in many regions.
Development Process
- Late 2023: New VTOL propulsion system tested and completed.
- May 2024: First extended-wing test flight, achieving over 8 hours of endurance.
- Late 2024: New battery layout and cruise power system verified.
- May 2025: Larger fuselage completed with additional internal space; endurance re-validated.
Reinforced VTOL Propulsion System
Vertical lift is one of the Y37’s defining strengths. Its VTOL system incorporates several key upgrades:
- Bamboo-node-style internal reinforcement for crack resistance and durability.
- Reversed downward-offset motor mount for reduced thrust loss during hover.
- Transitioned from 8S to 12S power, improving thrust capability and safety margin.
- New 24-inch VTOL propellers with enhanced stiffness and efficiency.
- Up to 13 kg single-axis thrust for stable vertical takeoff under higher payloads.
This VTOL design ensures stable performance even in high-temperature or high-altitude environments.
Extended High-Efficiency Wing
The new thin-profile composite wing brings a major boost to the aircraft’s energy efficiency:
- More than 40% improvement in lift-to-drag ratio.
- Optimized transition airfoil for efficient load distribution.
- Upgraded tail-wing mold using reinforced V-slot composite technology.
- Flight-validated in May 2024.
This advanced wing is a key contributor to the Y37’s long-endurance capability and smooth cruising performance.
High-Capacity Battery Architecture
The Y37 introduces a new CG-adjustable internal battery layout, maximizing energy storage while keeping balance flexible for different payload configurations.
- Total energy capacity: 12S 54,000 mAh (≈2700 Wh)
- Typical endurance with ~4 kg payload: ~5 hours
- Endurance with lighter payloads: up to 8 hours
This architecture also leaves room for future upgrades as battery technologies continue to evolve.
Redesigned Fuselage with Larger Payload Bay
The new fuselage maintains a lightweight monocoque structure while providing significantly more usable volume:
- Nose width expanded to 21 cm for larger gimbals or electronics.
- Large top opening for easier installation and servicing.
- Quick-release mounting for faster mission changes.
- Rear bay extended with dedicated antenna installation positions.
This makes the Y37 more flexible for multi-sensor configurations, long-range radio systems, and additional data equipment from Airmobi’s ecosystem, including long-range video transmission systems and flight control & GCS modules.

The fuselage continues to follow a classic frameless monocoque design.
The nose section has been widened to 21 cm, offering enough internal volume to hold five standard water bottles, demonstrating its increased payload accommodation capability.
A large top hatch is introduced to make equipment installation and maintenance easier.
The battery pack can be inserted directly from the front compartment, and the internal bay includes a quick-release mounting structure to support fast payload changes for different missions.
The rear compartment is also extended to provide additional space, along with a dedicated antenna-mounting area for communication modules.
The chart shows that the YUAV Y37 delivers the highest productivity in all mission scenarios.
Whether it’s long-range return flights, large-area mapping, high-altitude climbs, or payload efficiency, the Y37 consistently outperforms other UAVs by a wide margin.
This means fewer flights, larger coverage per mission, and significantly higher operational efficiency.
