Antiskidding device for a brake system

Abstract

Abstract 1. Antiskid device for a braking system wherein the speed of an aircraft to be slowed down and that of the wheels to be slowed down are measured, and comprising : a selection device generating a reference speed from at least one measured value of the aircraft speed when at least one measured value of said speed is acceptable, and generating a reference speed according to a substitution law in the contrary case, and an actuating circuit of an antiskid system producing a reduction of the braking action produced by a braking control system when the speed of at least one braked wheel is smaller than said reference speed, weighted by a coefficient of tolerated skidding, characterized in that the wheels to be slowed down constitute wheel groups comprising wheels arranged symmetrically with respect to the axis of the aircraft, each group comprising an actuating circuit, that it comprises at least two speed measurement devices (A to H) respectively associated with at least two groups of wheels to be slowed down and each comprising a measurement of the aircraft speed and a measurement of the speed of each of the wheels of the group, the releasing of braking occurring only in the groups of wheels where at least one wheel is close to the blocking conditions.
