First Flight of Brazil’s Albatroz Vortex Jet UAV With Domestic Turbine
Brazil’s Albatroz Vortex unmanned aerial vehicle completed its first flight with the domestically developed ATJR 15-5 jet turbine, marking a milestone for the country’s aerospace and defense industry. The test of the jet-powered drone took place at Santa Cruz Air Base in Rio de Janeiro and confirms integration of the Brazilian turbine with the aircraft.
The Albatroz Vortex flight, conducted on December 17, 2025, was publicly confirmed by Stella Tecnologia on January 22, 2026. The UAV is powered by the ATJR 15-5 turbine built by Aero Concepts, and the event was backed by the Brazilian Ministry of Defense and the Brazilian Air Force under a cooperative development agreement from November 2025.
What Happened in the Test Flight
The key goal of the flight was to confirm that the propulsion system operates as expected in real flight and that it works reliably with the Albatroz Vortex airframe. This real-world validation is essential for jet-powered UAV programs because it tests aerodynamic and structural integration that cannot be fully replicated in ground trials.
The flight successfully showed the turbine performing under flight conditions and verified that engine mounts, air intake, and aircraft systems integrate properly with the propulsion system.
Platform Background
The Albatroz Vortex is a jet-powered variant of the Albatroz family of UAVs developed by Brazil’s Stella Tecnologia. The Albatroz line is a tactical fixed-wing unmanned system with a maximum takeoff weight around 150 kg, previously flown with a piston engine. The jet variant adds a propulsion technology layer with higher potential speeds and operational altitudes.
The ATJR 15-5 turbine delivers about 500 newtons of thrust and represents one of the first Brazilian-built jet turbines to fly integrated with an operational UAV platform. Its development, including design, bench testing, and flight validation, was done in Brazil at Aero Concepts facilities in São José dos Campos.
Strategic and Industrial Implications
The first flight underscores ongoing efforts to strengthen Brazil’s aerospace industrial base and reduce reliance on foreign propulsion systems, which are often a bottleneck in advanced UAV development. The project is part of a broader national push to build strategic capabilities in unmanned systems and related technologies.
The cooperation between Stella Tecnologia, Aero Concepts, the Brazilian Air Force, and the Ministry of Defense reflects institutional support for domestic aerospace innovation. Testing will continue with further flights aimed at expanding the operational envelope and refining performance data.
Next Steps
Stella plans continued flight tests on the Albatroz Vortex in early 2026 to assess performance across a wider range of speeds and altitudes. Parallel work includes maturing production processes for the ATJR turbine family, intended to span thrust levels up to 5 000 newtons for a range of UAV classes.
