FIELD: water-jet power plants used for ship's motion. SUBSTANCE: water-jet propeller plant has hinge reciprocating linkage connected with drive and device for creating reactive force; hinge reciprocating mechanism is made in form of fixed bearing elongated member and at least two parallel rods mounted on either side from bearing member and articulated to cross-piece forming movable parallelogram; at one end, rods are connected with drive which ensures their reciprocating along bearing member and at opposite end, rods hold device for creating reactive force which is made in form of bladed wheel with rim and bush for free rotation on rod and radial spokes on which blades are articulated for limited turn; blades fully close cross section of bladed wheel at working stroke of rod outside. During working stroke, blades form cone-shaped closed member whose base is directed outside. EFFECT: enhanced reliability. 2 cl, 4 dwg |
