Conflux Technology, a leader in additive-manufactured heat exchangers, is developing hydrogen fuel cell cooling systems for AMSL Aero’s Vertiia VTOL (Vertical Takeoff and Landing) aircraft. AMSL Aero, an Australian manufacturer, is designing the world’s most efficient long-range, zero-emissions electric aircraft.
In the initial phase, Conflux created three heat-exchanger concepts to minimize weight, manage heat loads, and reduce drag, allowing for flight distances of up to 1,000 km. The project has now moved into its second phase, focusing on the optimization of a full proof-of-concept assembly to test its performance within Vertiia’s hydrogen fuel cell powertrain.
Michael Fuller, CEO of Conflux Technology, said, “Hydrogen fuel cells are key to Australia’s sustainable energy goals. Our heat exchange technology will improve the efficiency of Vertiia’s hydrogen fuel cells, advancing sustainable air transport.”
The cooling solution is designed for the transient heat loads experienced during Vertiia’s vertical takeoff, landing, and hover operations. Additive manufacturing allows for lightweight, high-performance heat exchangers that fit the limited space available in hydrogen powertrains while minimizing drag.
AMSL Aero Chairman Chris Smallhorn noted the synergy with Conflux, stating, “Conflux’s history of innovation in motorsport and aviation makes them the perfect partner for us as we build the Vertiia aircraft, which will fly at Formula 1 speeds.”
Simon Coburn, Hydrogen Systems Engineer at AMSL Aero, emphasized the importance of this collaboration in advancing clean energy and sustainable aviation.
The partnership further strengthens Conflux’s role in aerospace, as additive manufacturing continues to push the boundaries of thermal management in next-generation aviation systems.
