The Beluga whale, with its distinctive bulbous head, is the inspiration for this modular, multi-mission UAV.

Since its founding in Rome, Italy, in 1994, Eurolink Systems has been known primarily as a value-added distributor and integrator of mission-critical electronics for defence applications. Its customers include companies such as Leonardo, MBDA and Elettronica Group, along with other defence firms such as Thales.
In recent years it has also been drawing attention for its growing range of uncrewed vehicles that undertake missions across land and in the air, by reselling other companies’ systems and developing autonomous solutions in-house. As well as drawing on its own electronics r&d, including expertise in DSPs, GPUs, FPGAs, CPUs and power management boards, Eurolink has also worked with universities on r&d into advanced fluid dynamics, AI and other areas.
This combination of skills has been key to developing the Beluga UAV, Eurolink’s signature quadrotor craft for modular, multi-mission applications. The Beluga measures 980 x 630 x 450 mm, has a 10 kg MTOW (with 3 kg maximum payload), and an endurance of up to 60 minutes when carrying 1.5 kg of payload. Power comes from a 3.8 kg lithium-ion battery with 1 kWh of energy capacity.
The craft is notable for its distinctive hull shape, as it closely resembles a Beluga whale. While this provides some aesthetic appeal, the unique shape is a result of Eurolink’s approach to enhancing the UAV through bio-inspired aerodynamics.

Development timeline

Before starting development of the Beluga, Eurolink had established itself as a supplier to European militaries of US-manufactured electronics from numerous companies. That won it a contract in 2011 with the Carabinieri, one of Italy’s main law enforcement agencies, and which carries out primarily domestic and foreign policing duties.
After that, it agreed partnerships with several uncrewed systems companies, such as Slovenian UAS manufacturer C-Astral Aerospace (see UST 11, December 2016/January 2017), to distribute its Bramor and Atlas UAVs; this agreement has been extended to include sales of C-Astral’s new SQA eVTOL UAV. Another deal is with Edge Autonomy, which makes the Penguin series of UAVs (UST 1, November 2014 and UST 33, August/September 2020). “Soon after becoming a UAV reseller, we started some work of our own in robotics, developing UGVs for counter-IED work by the Italian army in Afghanistan,” says Pietro Lapiana, president of Eurolink Systems.

“The idea to create our own UAVs came 3 years ago, when we observed in the market that although there were thousands of drones being used around the world, most of them were essentially just bricks with arms. Add to that all their surrounding electronics, antennas and so on, and you find that many drones are rather inefficient aerodynamically.” As luck would have it, about a year ago a northern European military customer approached Eurolink with a request for a UAV capable of airspeeds of more than 100 kph and autonomous take-off and landing, for delivering blood for operating theatres potentially only 2-3 km from the front line. Another request was a flight endurance of an hour while carrying 1.5 kg of blood.

These provided Eurolink with a number of key specs that it needed to take from the concept stage through to prototyping. “As far as physic
