Silent Falcon Solar Electric UAV


Bye Aerospace provides design, research and engineering support for the Silent Falcon UAV being developed by Silent Falcon UAS Technologies.  The Silent Falcon is a solar electric UAV utilizing stored electric power, thin film solar photovoltaic (PV), high efficiency 6 blade propulsion system and other technologies to enhance its very long endurance, quiet operations and zero emissions.

An efficient electric motor provides the Silent Falcon with appropriate climb rates and efficient cruise which facilitates access to areas requiring surveillance.

The easily transportable Silent Falcon system is very quiet with low thermal signature to reduce detection. The Silent Falcon carries a proprietary sensor gimbal, “Falcon Vision,” with electro-optical and infrared camera on a lightweight mechanically and digitally stabilized gimbaled payload allowing the operator to keep eyes on target. With very long endurance the Silent Falcon provides multi-fold the value and capability of competitive systems.

Silent Falcon began initial customer deliveries in 2015.  The combination of remarkable persistence, payload and reduced acquisition and operating cost over similar-sized systems gives the Silent Falcon a significant advantage over competitors.
