Bental Industries Develops Unique Hybrid Motor for Mini and Mid-Size UAVs

Hybrid motor for mini UAV's.

Bental, Israel (SPX) Aug 25, 2006
Bental Industries has developed an innovative hybrid motor for mini to mid-size UAVs. During ignition of the UAV's internal combustion engine, the electric motor acts as a starter and activates the internal combustion engine.

The internal combustion engine becomes an alternator that charges the UAV's batteries and supplies electric energy to all the UAV's systems, such as: payload, servo-actuators, telemetry, and all other electrical components.

Leveraging the Operational Advantages of Electric Motor and Internal Combusting Engine Upon arrival at the target - in order to assure a quiet flight and a low thermal signature - the system disconnects the internal combustion engine and changes the alternator to an electric motor that maneuvers the UAV quietly over the target area.

After accomplishing the mission, the internal combustion engine is ignited by the electric motor that changes itself back to a starter, and after ignition to an alternator, and once again charges the UAV's batteries. Benefits of this advanced hybrid motor include fuel savings, quiet operation, reduced weight and size, and high survivability due to the low thermal and noise signatures during mission implementation.

A Full Range of Unique Solutions for UAVs

Bental offers a full range of on-board and payload systems for mini-UAVs. The company's solutions have an exceptional track record on the Heron, Searcher and Harpy platforms produced by Israel Aircraft Industries, and other mini-UAVs.

Bental's systems for integration into mini-UAVs include Motion Systems, Stabilized Gimbal Payload Systems for observation, Miniaturized Payloads, Auto-Pilot, Electronics for Navigation, Communications, Video Transmission, Location and Positioning.

Bental cooperates with Teleflight for the development of the Smallest Stabilized Gimbal Payload Systems in the world - 2.75", 4", and 8". These cutting-edge systems enable day and night operation and offer a system stabilization range of 50 to 200 micro radians and miniaturized payloads and electronics.

Addressing the challenges of mini and micro-UAVs, Bental's solutions provide exceptional stabilization, high resolution observation, small size and low weight. Bental recently released its newest line of unified Starter Generators (SGs) which start the UAV's main motor and other systems. Unifying two functionalities into one unit, the SGs substantially reduce weight and volume, while increasing the platform's endurance, safety, and ease of operation by ground operators.
