Zala Aero Group manages a growing stable of Russian-engineered Unmanned Aircraft Systems (UASs). The ZALA 421-20 series is one such offering intended for tactical service use. The product is marketed as a long-loiter Intelligence, Surveillance, Reconnaissance (ISR) platform and geared towards various industries including military, law enforcement, border protection, the oil sector, fire service and the like.
The 421-20 features a 50 kilogram payload capability, mounting various optics and sensor sets as needed. The platform can be used to laser-designate precision-guided munitions for accompanying attack aircraft, offer InfraRed (IR) high definition camera functionality and provide real-time over-battlefield data collection / transference to ground forces / commanders for further interpretation.
Available optics fits include a High Definition camcorder, thermal zoom and photo / video camera, all gyro-stabilized for maximum picture / video clarity.
Operational ranges reach out to 400 kilometers with a mission endurance window between six and eight hours. Maximum operating altitude is 5,000 meters with power provided from an internal combustion engine driving a bladed propeller unit in pusher configuration, giving the vehicle a speed up to 220 kilometers per hour. Onboard navigation is handled by an INS-corrected GPS / GLONASS system with electronic telemeter.
The overall design arrangement of the aircraft is of twin-boom allowing the central fuselage nacelle to house all pertinent mission equipment and the powerplant itself. The wing mainplanes are straight and shoulder-mounted to the fuselage. From the trailing edges the booms take shape and lead to vertical tail fins supporting a single horizontal plane. The fixed tricycle wheeled undercarriage arrangement allows for rough-field operations in both launching and retrieving the air vehicle.
