Scientific paper

A single-body one-dimensional ablation model has been developed in order to predict the entry behavior of large meteorites during their hypersonic drag interaction with the earth's atmosphere. The entry predictions are compared with multistation photographic data. Typical results indicate that the ablation parameter, sigma, approximately equals 0.02-0.03 sq sec/sq km in the vicinity of the peak ablation altitude.
