B-4 - Croatian military multipurpose unmanned aerial vehicle developed by «Soko ZI».

The unmanned aerial vehicle was developed by Croatian engineers and aircraft designers for military applications. Despite the relatively narrow scope of its operation, the unmanned aerial vehicle has very wide functionality, in particular, this drone can be used for reconnaissance missions, operated as patrol and observation means, used for targeting and adjusting artillery systems, etc. The main feature of this drone compared to similar unmanned aerial vehicles of European and American production, is its low cost, which led to the rapid promotion of UAV.

Croatian UAV model B-4 has a rather impressive and large dimensions, in particular, the length of the fuselage of this aircraft means is 4,2 meters and wingspan drone is 6 meters. Nevertheless, this factor did not have a negative impact on the aerodynamic properties of an unmanned air tool, which contributed to the optimized design of the UAV.

Multipurpose military unmanned aerial vehicle equipped with the power ustanvokoy includes a piston internal combustion engine, which is having a large enough capacity, can accelerate the drone to a maximum airspeed in 120 km \ h., At the same time, the effective radius of the air means the action is 200 kilometers, and duration of stay in the autonomous flight reaches 10 hours.
