Typical vibration modes of aircraft braking systems are discussed. Special attention is given to squeal vibrations of carbon brakes. From flight tests, a wide range of response amplitudes are analysed to determine the nature of the motion. Fourier analysis indicates the presence of a high amplitude limit cycle which seems to be iniciated by a transient chaotic region. A singular system approach based on a time delay embedding confirms this finding. Time delay analyses makes it possible to construct model equations via which intrinsic dynamics of the system can be recovered, and opens up the possibility of preventing large amplitude vibration by controlling the chaotic motion.
