Battery energy density is still a problem for designers who want to create electric aerial vehicles that can carry a decent payload for a useful distance, but the team at Tupan Aircraft believes it has come up with what it feels is a reasonable solution. Tupan’s family of high-speed, vertical takeoff and landing (HSVTOL) drones combines electric propulsion with tiny Jet-A fueled turbine engines to deliver speed, payload capacity, and redundancy in a compact and capable package.
Tupan is a start-up founded by a group of Brazilian engineers with years of experience in propulsion system design, flight testing, aerodynamics, and autonomous flight. The company, based in Jacarei near São Paulo, is working with Turbomachine in São José dos Campos on the development of the small turbine engines that are key to the design of the Tupan-1000, -2000, and -3000 vehicles.
