Durable, Efficient Hybrid Drone Engines & Propulsion Systems for Commercial UAVs

UAVHE is a leading developer of hybrid propulsion systems for commercial UAVs (unmanned aerial vehicles). We are committed to developing more environmentally-friendly unmanned aviation solutions that deliver significant savings to our clients not only in fuel costs but also in time, enabling drones to fly further and get more done in a single flight.

Our hybrid electric propulsion solutions deliver longer flight times for the same takeoff weight compared to purely electric systems, and consume less fuel than combustion-only aircraft. UAVs equipped with our engines are easy to control, making them accessible to pilots with a wide range of skill levels and experience.

All our engines are precision-machined from aerospace-grade materials, and have been engineered with a two-stage fuel injection system and an electric starter and booster. With a durable, low-vibration design, they are highly resistant to collisions and extremes of weather. Other key features include:

• Advanced autotuning
• CANbus control
• Extensive telemetry and self-diagnosis capabilities
• Electronic torque control and in-cycle torque compensation

Integration support for custom drone designs

UAVHE provides expert design and integration support for drone developers creating new concepts and prototypes for commercial, industrial and public safety UAS.

We can help you select the best hybrid propulsion solution for your new platform, and can customise our existing products to suit specific requirements and withstand harsh conditions such as moisture, dust, and extremes of temperature.
