PROBABILITY MODEL FOR IMPACTING DEBRIS,

Abstract

A procedure for determining the expected number of pieces of lethal debris per square nautical mile is given in the study. An example is completely worked out and the computer programs used to obtain the results are included in Appendixes to this report. The method is different from the usual approach in that it accounts for varying crossrange dispersion due to the wide range of the aerodynamic characteristics of the debris. This is accomplished by obtaining a probability density function which has a variable angle theta to account for the crossrange dispersion. The method is applicable whenever a power failure occurs of thrust is terminated while the vehicle is otherwise performing within its nominal flight limits. It is not applicable in cases where a malfunction results in a powered tumbling turn. (Author)
