For the second time, the Estonian Aviation Academy’s student team, Blue Sparrow, participated in the international unmanned aircraft competition, the IMechE UAS Challenge, held in the UK. Amidst growing competition, the team proved themselves by taking home two special awards.
The UAS Challenge, held for the 11th time, took place from 30 June to 3 July in Buckminster, UK, featuring a record 32 teams from around the world, including entries from China, Turkey, Portugal, the Netherlands, and more.
Blue Sparrow received recognition in two special categories:
🏆
Innovation Award
🏆
Operational Supportability Award
The concept for this year’s drone, developed by the 23-member Blue Sparrow team, originated over a year ago as part of the spring semester course “RPA Construction, Systems and Design”. The design was further refined and optimised during the autumn in accordance with the competition rules, with initial test flights taking place in November-December of last year.
According to participants, the EAVA’s drone attracted considerable attention, sparking curiosity among many. Comments from representatives of other universities and competition judges praised the design as bold, innovative, and forward-thinking. The drone’s technical solutions, assembly and production quality, as well as its operational readiness, were also highly commended.
This year’s Blue Sparrow drone features a hybrid configuration, combining a biplane airframe with a quad-rotor multirotor system. During takeoff, it operates like a multirotor, enabling vertical lift. To efficiently cover longer distances at higher speeds, the entire aircraft transitions to a horizontal position and uses its two wings to generate lift. This configuration results in a relatively simple and lightweight aircraft, capable of extended flights as well as vertical takeoff and landing (VTOL).
The maximum takeoff weight for the aircraft competing in the challenge is limited to 10 kg. It is designed for specific flight missions, with an autonomous system that performs tasks such as area search, waypoint navigation, precise delivery of a payload, and return to base along a designated route.
The Blue Sparrow project is funded by the Estonian Business and Innovation Agency (EAS) and KredEx joint support scheme for student engineering development projects. The students’ aircraft development has also been sponsored by Threod Systems and Origin.
