Most current long haul and heavy duty multi-rotor drones are powered by batteries. However, batteries only have approximately 1% energy density in unit weight of that of commonly used fuels, making long haul and heavy duty flights difficult. Microgas turbine generator is the best solution to the problem.
A variation of the TREx engine developed in the centre is an ideal power source for this application. It has much higher power to weight ratio than a piston engine and higher energy density than batteries.TREx has features in its radical design and advanced air bearings.
