ARIE EGOZI / TEL AVIV
Rafael plans to flight test its Skylark unmanned air vehicle next month. The Skylark is a man-portable system launched from a canister resembling a shoulder-launched anti-tank missile and is intended for frontline army units.
The electric-engined Skylark is 1.1m (3.6ft) long, has a 1.5m wingspan and a 120mm (4.7in) diameter, and weighs 6kg (13lb).
The UAV is boosted from the launcher by a pyrotechnic charge before the wings and tail are deployed.
Rafael says the UAV requires a "zero time to go" because of its unique launch system, adding that it can be launched from buildings and narrow streets. The UAV lands by flying into an arresting net.
The Skylark follows a series of preprogrammed waypoints during its flight of up to 1.5h. Its operational radius is 10km (5.4nm).
The payload comprises a daylight television camera while an infrared sensor is due to be ready early next year. Rafael claims the Skylark's optical payload is capable of identifying persons carrying arms.
The payload's images are transmitted to a small portable ground station before distribution to palmtop computers carried by unit commanders.
The company says it guarantees 36h of operational flying before an overhaul is required. After landing, the only requirement is to replace the battery and pyrotechnic charge before inserting the UAV into the canister ready for the next launch.
