FIELD: air transportation of bulk freights; construction of large industrial objects; military-transport aviation. SUBSTANCE: engine-propeller system includes load-bearing structure consisting of beams interconnected in single lattice surface. Engine-propeller units are located in attachment points over entire surface of structure. It may have convex, concave or flat form and any configuration. Number of surfaces carrying the engine-propeller units may range from 1 to 10. Freight is suspended by means of lines articulated with beams with the aid of locking and sliding unit. Resultant lift force Plift formed by sum of elementary components of forces generated by engine-propeller units is selected within the following range: I ≤ (Plift+Pfr):Pfr≤ 100, where Pfr is mass of freight. Motion of freight is effected through change of angle between Plift and Pfr. EFFECT: increased load ratio. 7 cl, 9 dwg
