Engine-in-a-Box Will Change How UAVs are Powered

Unmanned aerial vehicles (UAVs) are becoming more and more popular with the military, thanks to their surveillance and air strike applications. Because of this, it was only a matter of time before UAV engine technology would see an outside-of-the-box design. Meet the Engine-in-a-Box.

The size of a mini-refrigerator, the Engine-in-a-Box contains a fully-integrated proprietary propulsion system that includes a small gas turbine engine, filters, a 3 kW generator, a control system, an electronic display and a gas tank.

According to UAV Turbines (UAVT), the company that created the Engine-in-a-Box, aircraft propellers can be powered either directly from the gas turbine or electrically with DC motors.

Ranging from 20 hp to 150 hp, the boxed engine is intended for use with Group 3 and 4 UAVs. The U.S. Department of Defense defines these groups to consist of large and larger UAVs capable of around 1,320 lbs in maximum gross takeoff weight with a normal operating altitude of 18,000 ft. (for example, U.S. General Atomics Predator A and B). … (read more)
