Parafoil aircraft applicable to cylindrical space loading

The invention discloses a parafoil aircraft applicable to cylindrical space loading. The parafoil aircraft applicable to the cylindrical space loading comprises a parafoil body and a nacelle; the nacelle is entirely cylindrical, and comprises a control cabinet, a power cabinet and a load cabinet which are fixedly arranged in a laminated manner; two rope winding plates are arranged inside the control cabinet; an operation rope in the parafoil body is coiled on each rope winding plate; a main parachute cord is fixed with the both ends of a supporting rod which can be unfolded in the left-right direction and be mounted on the control cabinet; the parafoil body is unfolded by unfolding the supporting rod; and a steering engine controls the rope winding plates to rotate, so that the steering posture of the parafoil aircraft can be controlled. A motor for driving propellers arranged outside the power cabinet to rotate is mounted in the power cabinet, so that the parafoil aircraft climbs out and falls down. The load cabinet can be configured with various types of mission loads aiming at the parafoil aircraft. The parafoil aircraft applicable to the cylindrical space loading, provided by the invention, has the advantages that the high use ratio of the cylindrical space loading the aircraft can be realized; the large-area flexible punching parafoil is used as a lifting surface, so that the lower flight speed can be obtained, and the parafoil aircraft applicable to the cylindrical space loading is applicable to a long-term fixed-point reconnaissance mission; and meanwhile, the parafoil aircraft applicable to the cylindrical space loading has good vertical and transverse stability.
