Unmanned aerial vehicles (UAVs), or drones, for defense applications require low-noise propulsion systems comprised of fuel-to-electricity and electricity-to-thrust systems.

Calnetix Technologies’ Magnaforce™ high-speed motor generator systems meet the requirements for these UAVs, providing light-weight turbo alternators for airborne power generation and high-power densities for electric thrust. Calnetix motor generators eliminate the need for bulky gearboxes used to mechanically couple the UAV’s drive train system.  The resulting reduction in weight extends operational endurance and payload capabilities, while also reducing the sound range of the UAV.  Additionally, if the UAV has an energy storage unit, the electric propulsion will allow for an almost salient mode of operation.
