Fixed-Wing VTOL Drone Makes Successful Flight

ULC Robotics., a leader in developing and deploying innovative robotic technology and processes, announces it has successfully flight tested its newly developed fixed-wing VTOL UAV.

ULC Aerial Services is working with gas and electric utilities across the United States to develop the VTOL aircraft with the most beneficial commercial utility applications. Upcoming test flights and pilot programs utilizing the VTOL area critical step towards the VTOL’s ability to gather valuable imagery and data for enhancing utility infrastructure.

In order to collect specialized data for the divisions’ utility customers, ULC will be integrating a variety of sensor and monitoring payloads into the VTOL platform. The UAV will continue to be flight tested with radiometric thermal cameras and high-resolution DSLR imaging systems and, with the 10-pound payload capacity, more than one system can be included on the aircraft at a time. The company also plans to integrate LiDAR, gas leak detection sensors and other advanced systems onto the payload of the drone.


The UAV was designed and built from the ground up by ULC’s Aerial Services and engineering teams. The platform has a 10-foot wingspan and a sensor payload capacity of 10 pounds for conducting aerial inspections and assessments of a variety of utility structures and properties, including electrical transmission lines, gas transmission pipelines, and right of ways. The VTOL UAV has a set of 8 quadcopter rotors for VTOL. After reaching a predetermined altitude and airspeed, the aircraft transitions into highly-efficient, forward flight combining the practical functionalities of multi-rotor UAV and the speed and range of a fixed-wing aircraft.

The drone is currently running an electric propulsion system with a one to one-and-a-half hour flight time. In the near future, ULC Aerial Services intends to integrate an electric/gas hybrid propulsion system that will allow for a five-hour endurance and 50 mph cruise speed (250-mile range), laying the groundwork for BVLOS flight.

Present electric utility infrastructure inspection methods can be cumbersome requiring utilities to fly helicopters over the inspection site several times a year, which is costly and compromises the safety of the workers due to low airspeed and altitude. By implementing the use of the VTOL UAV, the data gathered will allow utility inspectors to assess infrastructure health from the safety of their desk, rather than in the air.
