BOLIDE FRAGMENTATION PROCESSES : SINGLE-BODY MODELING VERSUS THE CATASTROPHIC FRAGMENTATION LIMIT.

PDF Version Also Available for Download.

Description

The catastrophic 'pancake' fragmentation process, proposed as being generally applicable to very large meteoroid entry in the early 1990's by a number of workers, has been carefully examined. In this effort, the transition from the traditional single-body dynamics and energetics model to a catastrophic 'pancake' fragmentation process has been delineated. The key parameters are the {mu} parameter originally proposed by Levin and the fragmentation scale height, Hf, which we have derived from {mu}. It has been found that this break-up process can only occur for an optimum set of circumstances.
