SPARROW for Navy Drone Supply

BMT Receives Patent for SPARROW Package Transfer Device

by DRONELIFE Staff Writer Ian M. Crosby

Leading international design, engineering, science, and risk management consultancy BMT has obtained a patent from the UK Intellectual Property Office for its ‘SPARROW’ autonomous air-ground payload transfer device, ideal for military drone delivery in addition to civilian applications.

“BMT’s patent signals a new type of suspended robotic device: a device that takes over responsibility for the final moments of payload delivery, and better suited to challenging and sensitive environments. This small, highly-ruggedised robotic device could even autonomously collect packages as well as deliver them without the need for infrastructure on the ground,” said Phil Metcalfe, Regional Business Director for UK and Europe. “With the development of this autonomous and highly-versatile concept the project team have delivered a great example of how BMT actively applies its innovation to solve its customers’ complex problems. Further, we were super excited to participate in the British Army’s “Army Warfighting Experiment” (AWE) 23, with our rugged technology demonstrating the potential to feed into the army’s plans for a future ‘digital backbone.”

SPARROW addresses the problem of loud, obstructive delivery drones needing to land or hover low over the payload destination. Different from winch systems employed in current trials for delivery drones, SPARROW lowers both itself and the payload at the bottom of a line, with the top attached to the drone above. This offers greater control over the payload and enables the larger delivery drone to remain out of the way at a higher altitude. Significantly smaller than the drone and without requiring lift-generating rotors, SPARROW is ideal for safe and quiet deliveries.

“During 30 years of working in aerospace, I have not seen anything like the surge in new aircraft, systems, and applications that has happened in the last five years,” said Dr Steve Wright, BMT’s development partner from Wright Airborne Computing. “SPARROW is a perfect example of this revolution, fueled by a happy convergence of 21st century technologies harnessed together by computers and software that engineers like me could only dream about 30 years ago.”

Initially developed for defense applications, SPARROW was selected early in its development by the UK Ministry of Defense for the highly competitive “Army Warfighting Experiment”. Its first demonstration was held at HM Naval Base Portsmouth, UK, in November 2022 with the associated ”Exploitation Event” in February 2023.

“As the system is developed further, it will provide a capability unlike anything else known to Defence,” cited the the AWE 23 independent Product Assessment Report. “It would enable the use of UAS to deliver payloads in the most challenging terrain, reducing risk to both the airframe, the payload and personnel on the ground.”

In addition to defense applications, this solution has potential value for manned helicopter operations and in sectors such as Maritime Ship-Shore deliveries, support to maintenance engineers on tall structures, Emergency Services, and e-commerce domestic deliveries. The project is seeking to partner for further Research and Development and license the technology to established operators.
