HAMR Unmanned Aircraft Drone

After four years of development, Advanced Aircraft Company (AAC) has launched its first long-endurance hybrid-electric UAS.

Known as the Hybrid Advanced Multirotor Unmanned Aircraft System, or HAMR, the system features a multi-rotor configuration with a hybrid gas-electric propulsion system, AAC Founder/CEO Bill Fredericks said. Because fuel injection is computer controlled, the aircraft always receives the appropriate amount of fuel. The system automatically injects extra fuel for takeoff and then leans out during flight, making the long endurance drone more fuel efficient. It also features an aerodynamic frame design.
