An in-flight airframe vibration data sample taken from a propeller driven cargo aircraft is viewed in the wavelet and frequency domains, with an emphasis on propeller blade activity. Close examination in the wavelet domain reveals a mechanism by which this activity is shared between adjacent resolution levels, with subsequent wavelet packet decomposition demonstrating alternatives with fewer basis functions.Published
