System of tail fin is formed by horizontal air foils (41a, 41b, 43) and vertical air foils (42a, 42b) made to form ring structure containing ring fixed on fuselage. Traction engine is held in the ring formed by system of tail fin. Central vertical stabiliser is used to form two rings in the ring structure. Versions of aircraft are characterised by tail fin features and mounting of one or two engines in the ring zone.EFFECT: higher safety of operation.13 cl, 4 dwg |
