Braking system and method for a landing airplane in the phase after ground contact of the main landing gear until touch down of the nose wheel

摘要

The present invention relates to a method and brake control device.; The method for controlling the braking of an aircraft (1) during its atterrisage on a track (3) as soon as it has contacted the ground (2) by rolling means (6) of the main undercarriages (7) and previously before the working means (8) of the front landing gear (9) itself has contacted the ground comprises: - determining the value of the pitch angle Δ of the aircraft as soon as it contacts the track (2) by bearing means (6) of the main undercarriages (7) - developing a signal representative of the value of the pitch angle, - controlling the braking by any means of said aircraft as a function of a value representative of the signal to thereby obtain a variation of the angle of nose acceptable. Application to frainage aircraft.
