AIRCRAFT WING LEADING EDGE Russian patent published in 1994 - IPC

FIELD: aircraft industry. SUBSTANCE: guiding groove 6 of each rail 2 is made with additional area 14, located in front of stationary block 3 of wing leading edge slat 1 hanging. Front block 12 of hanging of fold 11 is engaged with guiding groove 6 of rail 2. In the case, program mechanism of fold 11 movement has cam, that ensures engagement of front block 12 of hanging of fold 11 with additional area 14 of guiding groove 6 rail 2 during extending leading edge slat 1 into taking off position. During extending leading edge slat 1 into taking off position, simultaneous movement of fold 11 takes place on front and rear blocks of hanging, that are located on wing leading edge slat 1 and on wing 5 and so slit free configuration is achieved. As wing leading edge slat 1 is under action of program mechanism with cam extended by big angles, fold is retracted. Aircraft wing leading edge is used in system of wing leading edge slats control. EFFECT: improvement of aerodynamic features of wing, simplification of structure, decrease of weight. 8 dwg
