The VRABAC is a high-wing monoplane made of composite materials. Its fuselage is aerodynamically shaped around the equipment. The nose part contains an 800W DC motor powered by a Li-pol battery while the space below and behind it is intended for electro-optical equipment. The airborne computer is in the central part. The UAV is hand launched and lands with a parachute and an airbag. It is designed to survey and analyze major infrastructural facilities such as pipelines, major roads, bridges, forests, etc.
