This Aerospace Information Report (AIR) describes a mathematical model that can be used to analyze particle count data. Particle counts that fit the model can be graphically displayed, converted from one counting size-frequency range to another, and extrapolated to estimate counts beyond the measured range. Derivation, applications and calculations are described.
This document has been determined to contain basic and stable technology which is not dynamic in nature. It is basically a mathematical analysis of particle counts which will not change with the advent of new technology.
