FIELD: mechanical engineering. SUBSTANCE: proposed device has turnable doors which can integrate into outer wall of gas flow channel behind fan at forward thrust and turn under action of movement control to form obstacle to gas flow deflection at reverse thrust. Each door as rear member in its rear portion in direction of gas flow. Rear member is hinge-connected with door and is furnished with mechanical tie with door made for displacement of rear member from position, corresponding to forward thrust operation when inner surface of rear member forms outer wall of channel so that forces acting onto rear member from flow side tend to hold door in non-open position, into position corresponding to operation of device at reversing when rear member is in retracted position beyond the limits of gas flow behind door. EFFECT: enhanced reliability and safety. 8 cl, 8 dwg
