System to lower the stresses applied to a wing, especially at the mast-base connection of the wings from a flying aircraft

摘要

The present invention relates to a system for lowering the forces applied to the wing structure and especially the wing root (1) of the wings (2) of an aircraft (3) in flight, comprising means (4) for detection and for measurement of the vertical acceleration gamma of the aircraft, and means (5) for supplying control signals to aerodynamic surfaces (6) linked to the wings (2) of the aircraft, said means of control (5) driving the deflection angle of the said aerodynamic surfaces (6) as a function of the acceleration signals which they receive. …??According to the invention, the said means of control (5) are activated only when the said vertical acceleration gamma exceeds a predetermined threshold gamma s.
