A landing system for a fixed-wing unmanned aerial vehicle (UAV), the system comprising a parachute arranged in a parachute compartment that is secured to a fuselage tail section, and suspension lines for securing to the fuselage are fixed in four points on a fuselage lower part symmetrically relative to the UAV's center of gravity. The parachute compartment interacts with a detachment mechanism secured on a bulkhead of the tail section and comprises pins that are hinged to rods secured on a central rotatable disc coupled to at least one servomotor by means of a spring-loaded rod, the pins are mounted in guides, free ends of the pins fit into corresponding holes along a parachute compartment perimeter. The system further comprises an airbag coupled to an impeller and arranged in an onboard compartment that is arranged in a fuselage upper part and closed with a hinged hatch cover.
A landing system for a fixed-wing unmanned aerial vehicle (UAV), the system comprising a parachute having a system of suspension lines that comprises suspension lines for securing to a fuselage, a central suspension line that is connected to upper ends of the fuselage suspension lines, and suspension lines of a parachute canopy, the parachute is arranged in a parachute compartment that is detachably coupled to a fuselage tail section and an airbag that is coupled to an impeller and arranged in an onboard compartment of the fuselage having a hinged hatch cover fixed thereon, wherein lower ends of the suspension lines for securing to the fuselage are fixed in four points on a fuselage lower part symmetrically relative to the UAV's center of gravity, the detachability of the parachute compartment is ensured by a mechanism that is secured on a bulkhead of the fuselage tail section and comprises at least three pins that are hinged to rods that are fixed on a central rotatable disc that is coupled to at least one servomotor by means of a spring-loaded rod, and the pins are mounted in guides such that free ends of the pins are capable of fitting into corresponding holes that are provided along a parachute compartment perimeter, the airbag onboard compartment is arranged in the fuselage upper part, and the hatch cover is fixed to the compartment by means of a lock having a servomotor and a detent that are configured to release the hatch cover, and the impeller is configured to be activated after unlocking the hatch cover lock that is configured to be actuated after activation of the parachute compartment detachment mechanism.
