UAVOS developed the R22-UV unmanned drone in collaboration with King Abdulaziz City for Science and Technology (KACST), a state-owned scientific institution based in Saudi Arabia.
R22-UV is intended for both military and commercial applications such as aerial video surveillance and monitoring, cargo transportation and delivery, radio relay, and agriculture.
The drone can also be used as a flying research and development laboratory for meteorological and hydrology surveys, and earth monitoring applications.
R22-UV incorporates a conventional rotorcraft design featuring an extended fuselage section, which integrated fixed landing gear, a main rotor, and a tail rotor.
The unmanned helicopter is 8.8m-long and 2.7m-high and features a two-bladed main rotor having a diameter of 7.7m. The tail section has a two-bladed tail rotor as well as vertical and horizontal stabilisers. The wheelbase of the helicopter is 1.8m.
Maximum take-off weight of the UAV is 635kg, the maximum payload carrying capacity is 40kg, and cargo capacity is 280kg.
The R22-UV’s skid type landing gear, with a level surface of 15mx15m, provides safe landing on difficult terrains.
The helicopter’s flexible design allows for operation in severe weather conditions. It also requires less operational life cycle costs. Time between overhauls (TBO) for the maintenance of the UAV is 300 hours.
