DEFLECTOR-VORTEX GENERATOR Russian patent published in 1999 - IPC

FIELD: aircraft manufacture. SUBSTANCE: deflector-vortex generator is made in form of triangular plate fitted on fuselage or on engine nacelle. Deflector-vortex generator gas leading edge sweep angle of χ_le = 70^°...76^° and chord b_dvg= (0,5...0,6)b_a,, where b_a- is mean aerodynamic chord of wing; it is fitted on fuselage at angle of ϕ_dvg ≈ 15^°...20^° in position at which longitudinal and vertical coordinates of wing trailing edge are equal respectively to and as related to chord. As a result, more stable flow around wing and side surface of fuselage is ensured, thus considerably enhancing lateral and longitudinal aerodynamic characteristics within range of near-stall of attack. EFFECT: enhanced longitudinal and lateral aerodynamic characteristics. 4 dwg
