Copyright: Tamir Eshel, Defense Update

Details & reference: The Damselfly, developed by Selex Sensors & Airborne Systems is a technology demonstrator of a vertical take off and landing (VTOL) Unmanned Air Vehicle (VTUAV) developed by the company by internal funding. The unique propulsion system utilizes high speed fan with thrust dispersal through four separate nozzles. Each nozzle also have steerable vanes, which adds control trim for stationkeeping and maneuverability. The independently movable are controlled by the flight control system to achieve controlled hovering and transit to forward flight. This propulsion system offers more versatile and survivable operation at low altitude and over cluttered terrain (forest, jungle, ship deck). An electrically powered version has already been flight tested and another version powered by gas turbine is epected to commenc eflight testing in September 2007.

The Damselfly will carry a video camera datalink housed in the wing-tip pods. As the design is resistant to wing gusting, Damselfly will be suitable for maritime and shipborne operations. This model was unveiled earlier in 2007 at the UAV demonstration at ParcAberporth Parc Aberport and again, on the Finmeccanica/Selex stand at DSEi 2007.
