FIELD: thrust reversing equipment. SUBSTANCE: thrust reverser of turbofan engine has rotary shutters 7 integrated during operation of given thrust reverser under condition of direct thrust into external wall of engine nacelle and forming deflecting obstacles for current of gases under condition of thrust reversing after corresponding turn of these shutters under action of driving hoist 8. Panel 20 front along current provides back-up for each shutter 7 from internal side. This shutter 7 and this panel 20 front along current turn about corresponding independent rotation axes 27, 28. Coupling between mentioned shutter 7 and panel 20 front along current is provided with the aid of so-called three-point lever 30 hinged in its first point 31 to some bracket 32 rigidly coupled to panel 20 front along current, coupled directly in its second point 33 to shutter 7 and to end of rod of mentioned driving hoist 8 in its third point 34 so that transfer of any moment of forces emerging due to availability of gas pressure in duct, acting on panel 20 front along current and facilitating opening of given shutter is prevented during operation of proposed thrust reverser under condition of direct thrust. EFFECT: reduced aerodynamic losses thanks to such design of thrust reverser. 1 cl, 4 dwg
