Scientific paper

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 μ parameter originally proposed by Levin and the fragmentation scale height, Hf, which we have derived from μ. It has been found that this break-up process can only occur for an optimum set of circumstances.
