Air Develop Japan (ADJ) https://aerodevelop.jp/ presented an ultra-compact gas turbine generator for large drones at Japan Drone 2022 (June 21-23, 2021, Makuhari Messe).
The developed ultra-compact gas turbine generator has an output of 30 kW for a weight of 30 kg, achieving an output per weight of 1 kW/kg, whereas the output per weight of drone power sources is about 0.2 kW/kg for lithium-ion batteries and 0.6 kW/kg for fuel cells.
When this ultra-compact gas turbine generator is applied to a large drone, it is expected to achieve an on-board weight of 50 kg and a flight time of one hour. “We have already received orders for large drones," said an ADJ representative.
ADJ will continue to develop a larger power output, targeting 500 kW, for use in flying vehicles that can carry multiple passengers. “In addition to large drones and flying vehicles, we would also like to take advantage of the high output per unit weight to develop applications such as portable emergency generators," said the ADJ representative.
