DEVICE FOR TURNING TRACTION VECTOR OF DOUBLE-FLOW JET TURBINE ENGINE Russian patent published in 2011 - IPC F02K1/70 F02K1/11 

FIELD: engines and pumps.

SUBSTANCE: device for turning the traction vector of double-flow jet turbine engine includes central body of gas generator of inner circuit and engine nacelle of fan of outer circuit with annular nozzle at the outlet, which contains reverse and diverting flaps of bucket shape, which are arranged in openings in rear part of engine nacelle along the opening periphery. Reverse flaps are fixed in rear part of each opening of engine nacelle on transverse axes, and each diverting flap is hinged on transverse axis with its reverse flap. Each reverse flap is equipped with an opening in which hollow diverting flap consisting of outer and inner walls with a channel between them is installed. Along longitudinal edges of engine nacelle openings, between engine nacelle and central body of gas generator the path of outer engine circuit is separated with radial pylons contacting reverse and diverting flaps. Each reverse flap is equipped on the outside in front part with fairing made in the form of hollow triangular annular sector. Diverting flap is arranged in reverse flap after fairing and hinged to the drive located in the fairing.

EFFECT: invention allows increasing lateral stability, vertical and transverse aircraft sensitivity at high angles of attack and at low flight speeds.
