The invention provides a novel parafoil and a steering and control method thereof. The parafoil comprises upper wing surfaces, lower wing surfaces, a plurality of wing ribs, two groups of parafoil ropes, two groups of steering ropes, two groups of straphangers and two steering straps. A plurality of flow guide holes are formed on two sides of each upper wing surface symmetrically, a flow guide vane is arranged on the inner side of each upper wing surface and at the position corresponding to each flow guide hole, a plurality of steering rope holes and the steering ropes penetrating the steering rope holes are arranged on two sides of each lower wing surface symmetrically, each flow guide vane is arranged between each upper wing surface and the corresponding lower wing surface, and each flow defector is connected with the corresponding steering rope. The steering ropes are stretched to drive the flow guide vanes to fold and unfold so as to control opening and closing of the flow guide holes, and directional steering and flared landing steering are realized. The novel parafoil has the advantages that aerodynamic performance of the parafoil is changed through the structures of the flow guide vanes, the flow guide holes and the steering ropes, weight of an existing steering mechanism is reduced greatly, steering force is low, the directional steering and the flared landing steering are realized simultaneously, and control accuracy is high.
