Special Study of the Environmental Effects on Storage Life
Abstract
The goal of this report is to develop models that predict ammunition shelf life based on the storage facility, location, duration of storage, and previous stockpile exposure. To accomplish the goal, life models were developed based on historical data. Calculations based on ambient temperature, solar radiation, wind velocity, ammunition temperature, magazine and pallet dimensions, and magazine physical property data (e.g., density, specific heat) were used to determine insulation factors between the ambient environment and the ammunition. Once the insulation factors are determined, ammunition temperatures can be predicted solely on ambient temperatures, wind velocity, and solar radiation exposure. Initially, sine functions were developed to define ambient temperatures. These functions relate ambient temperatures to the time of year allowing engineers to more effectively predict temperatures the ammunition will experience. Using this information, shelf life forecasts can be calculated analytically.
