FIELD: creating of lifting force and thrust and supercharging under pressure. ^ SUBSTANCE: proposed latticed-and-slotted system contains several working members-wings or blades or vanes which are fastened together and are connected with article by means of coupling components. relative position of working members in space is dictated by their successive forward and upward shifts in way of motion in medium and angle of turn around longitudinal axis, angle of attack beginning with first lower component. Parameters of relative position of each working member may be similar or different from member to member; they may be rigidly fixed by coupling members or may be changed by means of drive in case of considerable change in motion modes: takeoff, landing, acceleration and deceleration; provision is made for mechanically changing the angler of attack relative to medium of motion. Profiles and geometric sizes of each working member are similar or are partially different or different. Working members may be arranged in sections in one row or in modules consisting of two and more sections. ^ EFFECT: enhanced operational efficiency. ^ 4 cl, 19 dwg |
